SYSTEMS AND METHODS FOR DOMAIN-SPECIFIC TOKENIZATION
Systems and methods are provided for identifying a content domain associated with seed information, and searching metadata based on seed information. A processor receives seed information and accesses a database of tokens, each token associated with a content domain and each content domain associated with two or more tokens. For example, the content domain may be “Music” and the token may include “feat,” “with,” or “duet.” The processor determines whether a portion of the seed information matches a token in the database of tokens, and in response to determining that a portion of the seed information matches a token, the processor identifies the content domain associated with the matching token and determines whether at least some of the seed information, including the matching token, corresponds to some of the metadata in a database of data records.

This application claims priority to U.S. Provisional Application No. 61/496,463, filed Jun. 13, 2011 and incorporated by reference herein in its entirety.
BACKGROUNDSystems that catalog metadata about content elements may be called upon to perform two different tasks. The first task is catalog matching, in which records from two or more catalogs (e.g., databases of media content metadata) are aggregated by matching records in one catalog to records in another catalog. The second task is searching, in which a user or client application submits a request for information (often just a text string) and, in response, the system interrogates the catalog to provide appropriate information about media content. In each of these tasks, the system is called upon to compare some seed information (i.e., a metadata field from a first record in the catalog matching task, or a text string input by a user in the searching task) with a corpus of cataloged information (i.e., the records of an existing catalog in the catalog matching and searching tasks). One way of approaching both of these tasks is to search for the identical information within the catalog, but this approach is likely to be very slow when the catalog is large. More sophisticated search and matching methodologies may be used, but these methodologies may impose greater computational requirements.
SUMMARYDescribed herein are systems and methods for improving search and cataloging tasks by identifying the interest domains that are most likely to be relevant to a particular task. These content domains are identified by analyzing and transforming the information (referred to as “seed information”) provided to the search or cataloging task. Seed information may be any data that is used to describe content elements or media attributes of interest (e.g., a text string, an image, or a sound). In some implementations, a first processor receives seed information from a second processor and accesses a database of tokens, each token associated with a content domain and each content domain associated with two or more tokens. For example, the content domain may be “Music” and the token may include “feat,” “with,” or “duet.” The first processor determines whether a portion of the seed information matches a token in the database of tokens. If a portion of the seed information matches a token, the first processor identifies the content domain associated in the database with the matching token, and accesses a database of data records for the identified content domain. This database includes data records representative of content elements in the identified content domain (e.g., titles or genres in the content domain “Books”), with each data record including metadata descriptive of the associated content element. The first processor then determines whether at least some of the seed information, including the matching token, matches some of the metadata in the database of data records. If a data record with matching metadata is found, the first processor may transmit an identifier for that data record to the second processor.
In some implementations, if at least some of the seed information matches some of the metadata in the database of data records, the processor may store an association between at least some of the seed information and the second record. The seed information may be metadata of a first record, in which case storing an association between at least some of the seed information and the second record may include storing an association between the first and second records. The first and second records may represent a common content element, in which case storing an association between the first and second records may include storing the metadata of the first record and the metadata of the second record as metadata of a common record for the common content element. Storing an association between the first and second records may include storing the metadata of the first record as metadata of the second record in the database of records. The seed information may be transmitted from a user device, in which case storing an association between at least some of the seed information and the second record may include displaying some of the metadata of the second record at the user device.
In some implementations, each token in the database of tokens is also associated with an operative expression, which may indicate the meaning of the token within the seed information. In response to determining that a portion of the seed information matches a token, the processor may generate a query based on at least some of the seed information and the operative expression associated with the token. The processor may use the query to search the database of records.
The above and other objects and advantages of the systems and methods of the present disclosure will be apparent upon consideration of the following detailed description, taken in conjunction with the accompanying drawings, in which like reference characters refer to like parts throughout, and in which:
The systems and methods described herein take advantage of the different characteristics of metadata in different content domains to improve existing search and cataloging methodologies. In particular, the systems and methods described herein identify tokens within seed information, which may have specific meanings within particular content domains. For example, in the music domain, seed information may take the form “A feat. B” where A and B are the names of individual artists. Once a token such as “feat.” is identified in the seed information, the systems and methods described herein may use the token to identify the most relevant content domains in which to search, use a particular meaning of the token in forming a search query, or both. For example, once a system identifies “feat.” as a token within seed information, the system may then identify “music” as the most relevant content domain associated with the seed information, identify an operative expression associated with the seed information, including the token, (i.e., “Artist(A) AND Artist(B),” indicating that the “Artist” metadata field in a matching record should contain both A and B), or both. By extracting domain-specific information from tokens, the systems and methods described herein improve catalog matching and searching applications, as well as related applications undertaken in search and recommendation systems.
These systems and methods may be particularly useful in cataloging and searching applications that span multiple content domains. For example, when a user is allowed to enter seed information that will simultaneously search across music, movies and celebrities, it can be difficult to determine in which content domain a user is interested. If the system identifies a domain-specific token in the seed information, the system has a place to start in determining the most appropriate content domains from which to provide information to the user. When the system recognizes a token that is used in different domains (and perhaps in different ways), the system may be configured to disambiguate the token based on additional information, such as a user-specified content domain (e.g., specified via a radio button selection in a web-based interface) or from contextual information (e.g., when the user has been browsing in the “Movies” section of an online media store).
The search and cataloging systems and methods disclosed herein may be readily applied to any interactive application (e.g., interactive software, interactive websites, interactive television programs, and interactive presentations) or static application that includes aggregating data for transmitting recommendations to one or more users (e.g., a magazine feature providing product recommendations to different types of readers). As used herein, the term “recommendation” should be understood to mean information chosen to appeal to a user or group of users. Recommendations may be explicit (e.g., by presenting a particular book in a “Recommended For You” display on a website) or implicit (e.g., by presenting an advertisement for a particular product expected to appeal to a particular user or group of users). For illustrative purposes, this disclosure will often discuss exemplary embodiments of these systems and methods as applied in media guidance applications, but it will be understood that these illustrative examples do not limit the range of applications which may be improved by the use of the systems and methods disclosed herein.
The amount of information available to users in any given search, recommendation or content delivery system can be substantial. Consequently, many users desire a form of media guidance through an interface that allows users to efficiently navigate content selections and easily identify content that they may desire. An application that provides such guidance is referred to herein as an interactive media guidance application or, sometimes, a media guidance application or a guidance application. In particular, the cataloging techniques disclosed herein may be advantageously utilized by guidance applications (e.g., as part of the guidance data source from which the guidance application draws information).
Interactive media guidance applications may take various forms depending on the content for which they provide guidance. One typical type of media guidance application is an interactive television program guide. Interactive television program guides (sometimes referred to as electronic program guides) are well-known guidance applications that, among other things, allow users to navigate among and locate many types of content. As referred to herein, the term “content” should be understood to mean an electronically consumable user asset, such as television programming, as well as pay-per-view programs, on-demand programs (as in video-on-demand (VOD) systems), Internet content (e.g., streaming content, downloadable content, webcasts, etc.), video clips, audio, content information, pictures, rotating images, documents, playlists, websites, articles, books, electronic books, blogs, advertisements, chat sessions, social media, applications, games, descriptions of media assets (e.g., year made, genre, ratings, reviews, etc.) and/or any other media or multimedia and/or combination of the same. Guidance applications also allow users to navigate among and locate content. As referred to herein, the term “multimedia” should be understood to mean content that utilizes at least two different content forms described above, for example, text, audio, images, video, or interactivity content forms. Content may be recorded, played, displayed or accessed by client devices, but can also be part of a live performance.
One of the functions of the media guidance application is to provide media guidance data to users. As referred to herein, the phrase, “media guidance data” or “guidance data” should be understood to mean any data related to content, such as metadata, recommendations, media listings, media-related information (e.g., broadcast times, broadcast channels, titles, descriptions, ratings information (e.g., parental control ratings, critic's ratings, etc.), genre or category information, actor information, logo data for broadcasters' or providers' logos, etc.), media format (e.g., standard definition, high definition, 3D, etc.), advertisement information (e.g., text, images, media clips, etc.), on-demand information, blogs, websites, and any other type of guidance data that is helpful for a user to navigate among and locate desired content selections.
Display 100 may also include advertisement 124, video region 122, and options region 126. The item advertised in advertisement 124 and/or the format of advertisement 124 (e.g., interactive or passive, animated or static) may be selected using the recommendation techniques described herein. Video region 122 may allow the user to view and/or preview programs that are currently available, will be available, or were available to the user. The content of video region 122 may correspond to, or be independent from, one of the listings displayed in grid 102. Grid displays including a video region are sometimes referred to as picture-in-guide (PIG) displays. PIG displays and their functionalities are described in greater detail in Satterfield et al. U.S. Pat. No. 6,564,378, issued May 13, 2003 and Yuen et al. U.S. Pat. No. 6,239,794, issued May 29, 2001, which are hereby incorporated by reference herein in their entireties. PIG displays may be included in other media guidance application display screens of the embodiments described herein.
Options region 126 may allow the user to access different types of content, media guidance application displays, and/or media guidance application features. Options region 126 may be part of display 100 (and other display screens described herein), or may be invoked by a user by selecting an on-screen option or pressing a dedicated or assignable button on a user input device. The selectable options within options region 126 may concern features related to program listings in grid 102 or may include options available from a main menu display. Features related to program listings may include searching for other air times or ways of receiving a program, requesting programs similar to or recommended based on a program, recording a program, enabling series recording of a program, setting a program and/or a channel as a favorite, purchasing a program, or other features. Options available from a main menu display may include search options, VOD options, parental control options, Internet options, cloud-based options, device synchronization options, second screen device options, options to access various types of media guidance data displays, options to subscribe to a premium service, options to edit a user's profile, options to access a browse overlay, or other options.
Another display arrangement for providing media guidance is shown in
In some implementations, a media guidance application is implemented on a client server, which receives data from a media guidance data source (such as media guidance data source 368) and uses that data to provide a media guidance application to one or more client devices. In some implementations, the media guidance application executes directly on the client device; in this case, the client device is itself a client of the media guidance data source. As used herein, the term “client” or “client device” should be understood to mean any device that receives media guidance data (such as recommendations) from a media guidance data source. A user device, then, is a particular example of a client device. Client devices 374 may be coupled to communications network 364. Namely, user television equipment 352, user computer equipment 354, and wireless user communications device 356 are coupled to communications network 364 via communications paths 358, 360, and 362, respectively. Client devices 374 may include client data server 376, which has additional client devices: user television equipment 378, user computer equipment 380, and wireless user communications device 382. Communications network 364 may be one or more networks including the Internet, a mobile phone network, mobile voice or data network (e.g., a 4G or LTE network), cable network, public switched telephone network, or other types of communications network or combinations of communications networks. Paths 358, 360, 362, 388, 390, 392 and 394 may include any of the communication paths described above in connection with paths 370 and 372. Paths 362 and 394 are drawn with dotted lines to indicate that, in the exemplary embodiment shown in
Client devices 374 of
An operator may send instructions to control circuitry 304 using input interface 310. Input interface 310 may be any suitable interface, such as a remote control, mouse, trackball, keypad, keyboard, touch screen, touchpad, stylus input, joystick, voice recognition interface, or other input interfaces. Display 312 may be provided as a stand-alone device or integrated with other elements of client device 300. Display 312 may be one or more of a monitor, a television, a liquid crystal display (LCD) for a mobile device, or any other suitable equipment for displaying visual images. In some embodiments, display 312 may be HDTV-capable. In some embodiments, display 312 may be a 3D display, and the interactive media guidance application and any suitable content may be displayed in 3D. A video card or graphics card may generate the output to the display 312. The video card may offer various functions such as accelerated rendering of 3D scenes and 2D graphics, MPEG-2/MPEG-4 decoding, TV output, or the ability to connect multiple monitors. The video card may be any processing circuitry described above in relation to control circuitry 304. The video card may be integrated with the control circuitry 304. Speakers 314 may be provided as integrated with other elements of client device 300 or may be stand-alone units. The audio component of videos and other content displayed on display 312 may be played through speakers 314. In some embodiments, the audio may be distributed to a receiver (not shown), which processes and outputs the audio via speakers 314. In some implementations, client device 300 may not include one or more of display 312 and speakers 314.
Information from database 414 may be transmitted (by one or more servers associated with database 414) to data mining processor 412. Data mining processor 412 is configured to extract information from database 414 and process the extracted information to reconcile information from multiple sources (e.g., data records from multiple catalog management systems). In some implementations, data mining processor 412 includes a memory device configured as a database for storing one or more tokens used in performing the domain-based tokenization techniques described in detail below. Data mining processor 412 may also transmit the reconciled information to core content relations management (“CCRM”) module 408. As used herein, the term “module” should be understood to mean a processing device executing programming logic, such as source code, or higher-level code (e.g., Java code executed via a Java compiler), stored in a memory device (e.g., RAM, ROM, removable memory media, Flash memory, optical dishes, etc.). In some implementations, CCRM module 408 includes a MySQL database of reconciled data. Systems and methods for reconciling data in an aggregate catalog, which may be implemented by data mining processor 412 in conjunction with CCRM module 408 and the rest of offline component 402, are described in co-pending application ______, entitled “Systems and methods for transmitting content metadata for multiple data records” (Attorney Docket No. 003597-0608-101), which is incorporated by reference herein in its entirety.
CCRM module 408 may also receive information from editorial influence module 410. In some embodiments, editorial influence module 410 receives metadata from human or computer editors, and augments the information that is automatically catalogued with this “editorial” metadata. Editorial influence module 410 includes a server configured to provide a web-based interface between human editors and the database of CCRM module 408. In some implementations, editorial influence module 410 includes a Java application running on an Apache Tomcat web server, but may be executed on any processing device or devices with a user interface. Human editors may interact with the web-based interface using a personal computer connected to the Internet, a hand-held device, or any of the client devices (such as client device 300 of
Information from database 414 may also be transmitted (e.g., by one or more servers associated with database 414) to export/index processor 416. Export/index processor 416 queries CCRM module 408 to extract catalog information from CCRM module 408 and formats this information for use in different modules of real-time component 404 (as described in detail below). Export/index processor 416 may be configured to extract information in batches on a regular interval (e.g., every twenty-four hours) and format and transmit this batched information to a dependent module, or may be configured to extract information as it is updated in CCRM module 408. As shown in
Real-time service processor 418 receives information from domain relations module 420, metadata module 422 and search indices module 424, as described above, and provides recommendation information to client devices (such as client device 300). The components of catalog and recommendation system 400 may be distributed between multiple processing and storage devices; for example, the components of catalog and recommendation system 400 may be divided between media guidance data source 368, media content source 366 and client data service 376 (
Real-time service processor 418 also communicates with profiles database 426, which may include a data storage device configured as a database for storing information about client preferences, client equipment, client event history, or other information relevant for transmitting recommendations and data to a client. In some implementations, profiles database 426 stores profile information individual users (who may be users of an intermediate client service). Media guidance applications (such as recommendation applications) may be personalized based on a client's preferences as stored in profiles database 426. A personalized media guidance application allows a client to customize displays and features to create a personalized “experience” with the media guidance application. The customizations may include preferred sources of content metadata, varying presentation schemes (e.g., color scheme of displays, font size of text, etc.), aspects of content listings displayed (e.g., only HDTV or only 3D programming, client-specified broadcast channels based on favorite channel selections, re-ordering the display of channels, recommended content, etc.), desired recording features (e.g., recording or series recordings for particular users, recording quality, etc.), parental control settings, customized presentation of Internet content (e.g., presentation of social media content, e-mail, electronically delivered articles, etc.) and other desired customizations. This personalized experience may be created by allowing a client (such as a user) to input these customizations and/or by the media guidance application monitoring user activity to determine various user preferences.
Clients may access their personalized guidance application by logging in, communicating with catalog and recommendation system 400 using a designated protocol over path 440, or otherwise identifying themselves to the guidance application. The media guidance application may allow a client to provide profile information for profiles database 426 or may automatically compile profile information. The media guidance application may, for example, monitor the content the client accesses and/or other interactions the user may have with the guidance application, including responses to and feedback based on recommended content. Profiles database 426 may communicate with event database 436, which may store event records that contain information about client interactions with catalog and recommendation system 400. Profiles database 426 may access event database 436 to reconstruct a client's history of use of catalog and recommendation system 400 and to determine content preferences. Additionally, the media guidance application may obtain all or part of other profiles that are related to a particular client (e.g., from other web sites on the Internet the client accesses, such as www.allrovi.com, from other media guidance applications the client accesses, from other interactive applications the client accesses, from another device of the client, etc.), and/or obtain information about the client from other sources that the media guidance application may access. As a result, a client can be provided with a unified guidance application experience across the client's different devices. This type of experience is described in greater detail below. Additional personalized media guidance application features are described in greater detail in Ellis et al., U.S. Patent Application Publication No. 2005/0251827, filed Jul. 11, 2005; Boyer et al., U.S. Pat. No. 7,165,098, issued Jan. 16, 2007; and Ellis et al., U.S. Patent Application Publication No. 2002/0174430, filed Feb. 21, 2002, which are hereby incorporated by reference herein in their entireties.
Real-time service 418 transmits information to and receives information from client devices by way of path 440 and device gateway 434. As described above with reference to paths 370 and 372 of
Dispatcher processor 506 is also in communication with a number of service modules in web service tier 532, including REST v1 service module 520, REST v2 service module 522, and SOAP service module 524. These different service modules provide interfaces and transport mechanisms for accessing the “back-end” processing and data of orchestration tier 532. REST and SOAP are two different ways of packaging input and output data, and any other such protocols may be used. In some embodiments, service processor 500 includes processing and networking hardware configured with a software platform for serving dynamically generated recommendations applications in XML and JSON.
In some embodiments, index/export module 416 (
The types and structure of data specified in a contract may take any of a number of forms. For example, a recommendation system may receive a search or other query and may return pointers to media assets and fields containing metadata about those media assets. Thus, in some configurations of service processor 500 (
The above systems may be configured to perform any of the domain-specific tokenization techniques described herein, which may improve existing search and cataloging methodologies. Although the techniques described below may be described as executed by data mining processor 412 or real-time service processor 418 (
In memory structure 600, each token is a text string. These text strings may include any combination of numbers, letters, symbols, punctuation marks and other textual characters, in any language or character array. In some implementations, one or more tokens are graphical tokens that data mining processor 412 is configured to recognize within images, video, and other graphical content. For example, a broadcaster's graphical logo may be a token that data mining processor 412 can identify within a streaming video. In some implementations, one or more tokens are audio tokens that data mining processor 412 is configured to recognize within audio files, or audio portions of multimedia files. For example, the “NBC chimes” may be a token that catalog and recommendation system 400 can identify within an audio recording.
Content domain fields 604 identify content domains associated with tokens. For example, token entry 608 indicates that any of one of the tokens “feat.”, “ft.” and “feat” is associated with the content domain “Music.” The association between the tokens of token entry 608 and the content domain “Music” indicates that any of the tokens “feat.”, or “ft.” or “feat” may be used in search queries and textual information that describe content elements in the “Music” domain. In memory structure 600, token entries 608 and 610 include content domain “Music,” token entry 612 includes content domain “Movies,” token entries 614 and 616 include content domain “Video,” token entry 618 includes content domain “Books” and token entry 620 includes content domain “Games.” The data in which a token may be identified is referred to herein as “seed information,” many examples of which are given throughout this disclosure. If a same token is associated with multiple content domains (e.g., the token “rating” associated with “Movies” and “Games” in token entries 612 and 620, respectively), memory structure 600 may reflect this by including the multiple content domains in the content domain field 604 associated with the entry for that token, or by including separate entries for the token for each associated content domain.
Operative expression fields 606 identify operative expressions associated with tokens. Operative expressions indicate the meaning of the token within the seed information, and may be used along with the rest of the seed information to form queries for searching a catalog. Operative expressions may include combinations of logical operators, arithmetic operators, search operators, and calls to functions such as signal processing functions, filtering functions, memory retrieval functions, or any other functions. For example, the association between the “duet” token in token entry 610 and the operative expression “STRING1 STRING2 token->Artist(STRING1) AND Artist(STRING2)” indicates that the text string “duet” may be interpreted as meaning that, when a text string is received that includes two sub-strings followed by the token “duet,” that text string indicates a content element in which each text string appears in the “Artist” metadata field of that element. In memory structure 600, token entry 608 includes operative expression “STRING1 token STRING 2->Artist(STRING1) AND Artist(STRING2),” token entry 612 includes operative expression “STRING token->MPAA(STRING),” token entry 614 includes operative expression “token STRING->PrimaryCast(STRING),” token entry 616 includes operative expression “token STRING->SupportingCast(STRING),” token entry 618 includes operative expression “token STRING->Author(STRING)” and token entry 620 includes operative expression “STRING token->ESRB(STRING).” The syntax used in operative expression fields 606 is purely illustrative, and any syntax may be used. When tokens are associated with an operative expression, a token that is associated with multiple content domains may also be associated with multiple different operative expressions (e.g., the token “rating” associated with “Movies” and “Games” and the operative expressions “STRING token->MPAA(STRING)” and “STRING token->ESRB(STRING)” in token entries 612 and 620, respectively). A token may also be associated with the same operative expression across different content domains.
At step 704, data mining processor 412 accesses a database of tokens. This database may include a memory structure like memory structure 600 of
At step 706, data mining processor 412 determines whether a portion of the seed information received at step 702 matches any of the tokens in the token database (e.g., in any of token fields 602 of memory structure 600 of
If data mining processor 412 determines at step 706 that no portion of the seed information matches a token in the database, data mining processor 412 may return to step 702 and wait for additional seed information before invoking the token identification steps 704 and 706 again (and may instead, for example, proceed to analyze the seed information received at step 702 using other techniques). If data mining processor 412 determines at step 706 that a portion of the seed information does match a token in the database, data mining processor 412 identifies the content domain associated with the matching token at step 708, using the database of tokens (e.g., memory structure 600 of
At step 710, after data mining processor 412 has identified a matching token at step 706 and the associated content domain at step 708, data mining processor 412 may store an association between the seed information and the content domain identified at step 708. The location and nature of the storage at step 710 may depend upon the application for which the process of
At step 712, data mining processor 412 accesses a database of data records representative of content elements within the content domain identified at step 708. In some implementations, this database of data records is part of CCRM module 408 (
At step 714, data mining processor 412 determines whether at least some of the seed information, including the matching token, corresponds to some metadata of any of the data records in the database. Data mining processor 412 may use any of the “matching” techniques described above (with reference to step 706) in making the determination at step 714. Data mining processor 412 also looks for matches between different portions of the seed information and two or more different metadata fields within a single data record, which may indicate a stronger correspondence between the seed information and that data record then of only a single metadata field in that data record matched some of the seed information. The correspondence determined at step 714 may also include determining that the corresponding data record is consistent with any operative expressions associated with the token, as described in detail below. Based on the determination of step 714, data mining processor 412 may identify one or more records that correspond to the seed information.
At step 716, data mining processor 412 transmits identifiers for the corresponding data records to the second processor (which provided the seed information received at step 702). The identifiers may be one or more memory addresses for the corresponding data records, a VRL or other identification code that can be used to retrieve the corresponding data records, or the data records themselves. In some implementations, the second processor may use the matching data records to, for example, provide recommendations or populate a display on a client device. In some implementations, the identifiers are transmitted at step 716 to a device other than the second processor (instead of or in addition to the second processor), such as another component in catalog and recommendation system 400 or directly to a user device downstream of the second processor.
In implementations in which tokens are associated with operative expressions as well as content domains, data mining processor 412 or real-time service processor 418 (
At step 804, data mining processor 412 generates a query based on the seed information and the operative expression identified at step 802. To generate this query, data mining processor 412 may follow the instructions provided by the operative expression, as described above with reference to
As discussed above, the
At step 1004, data mining processor 412 receives seed information (e.g., as described above with reference to step 702 of
Using token 1134 and the process described above with reference to
As described above, in some implementations, a token may be associated with one or more content domains. In such implementations, it may be useful to have non-token-based techniques for determining which content domains are most likely to be associated with seed information (e.g., in order to narrow down the number of records that must be searched to identify data records relevant to the seed information).
At step 1202, real-time service processor 418 determines whether a client has selected a domain (e.g., through input interface 310 of client 300 of
If real-time service processor 418 determines that another client input has not indicated a domain at step 1204, real-time service processor 418 executes step 1206 and determines whether a media type selected by the client indicates a domain. For example, if a client device requests information in MP3 format, real-time service processor 418 may determine that the media type (MP3) indicates the “Music” or “Audio” domains. If real-time service processor 418 determines that a selected media type has indicated a domain at step 1206, real-time service processor 418 proceeds to step 1212 and identifies a content domain accordingly. If real-time service processor 418 determines that a domain is not indicated by a selected media type at step 1206, real-time service processor 418 proceeds to execute step 1208 and determines whether an event history indicates a domain. An event history may be any stored information regarding previous actions or requests by the client, and may provide domain information in any of a number of ways. For example, if a client has issued three requests for information in the past few minutes, all of which were identified as associated with the “Games” domain, real-time service processor 418 may determine that newly received seed information is also likely to be associated with the “Games” domain. If a high percentage of a client's previous requests at a particular time of day have been associated with the “News” domain, real-time service processor 418 may determine that new seed information received at that time of day is also likely to be associated with the “News” domain. If real-time service processor 418 determines that an event history has indicated a domain at step 1204, real-time service processor 418 proceeds to step 1212 and identifies a content domain accordingly. If real-time service processor 418 determines that the event history does not indicate a domain at step 1208, real-time service processor 418 proceeds to execute step 1210 and determine whether a client profile indicates a domain. If real-time service processor 418 determines that an event history has indicated a domain at step 1204, real-time service processor 418 proceeds to step 1212 and identifies a content domain accordingly. If real-time service processor 418 determines that a client profile does not indicate a domain at step 1210, real-time service processor 418 may return to execute 1202 and wait for additional seed information before invoking steps 1202-1210 again (and may instead, for example, proceed with any requested operations without relying on an identified content domain).
The following discussion addresses further embodiments of display screens, client devices and systems suitable for use with the asset cataloging, search, and recommendation techniques described herein. As noted above, the following discussion will often be presented in the context of media guidance applications, but it will be understood that these illustrative examples do not limit the range of interactive applications which may be improved by the use of the asset cataloging, search, and recommendation techniques of the present disclosure.
With the advent of the Internet, mobile computing, and high-speed wireless networks, users are accessing media on client devices on which they traditionally did not. As referred to herein, the phrase “client device,” “user equipment,” “user device,” “electronic device,” “electronic equipment,” “media equipment device,” or “media device” should be understood to mean any device for accessing the content described above, such as a television, a Smart TV, a set-top box, an integrated receiver decoder (IRD) for handling satellite television, a digital storage device, a digital media receiver (DMR), a digital media adapter (DMA), a streaming media device, a DVD player, a DVD recorder, a connected DVD, a local media server, a BLU-RAY player, a BLU-RAY recorder, a personal computer (PC), a laptop computer, a tablet computer, a WebTV box, a personal computer television (PC/TV), a PC media server, a PC media center, a hand-held computer, a stationary telephone, a personal digital assistant (PDA), a mobile telephone, a portable video player, a portable music player, a portable gaming machine, a smart phone, or any other television equipment, computing equipment, or wireless device, and/or combination of the same. In some embodiments, the client device may have a front facing screen and a rear facing screen, multiple front screens, or multiple angled screens. In some embodiments, the client device may have a front facing camera and/or a rear facing camera. On these client devices, users may be able to navigate among and locate the same content available through a television. Consequently, media guidance may be available on these devices, as well. The guidance provided may be for content available only through a television, for content available only through one or more of other types of client devices, or for content available both through a television and one or more of the other types of client devices. The media guidance applications may be provided as on-line applications (i.e., provided on a web-site), or as stand-alone applications or clients on client devices. The various devices and platforms that may implement media guidance applications are described in more detail below.
In addition to providing access to linear programming (e.g., content that is scheduled to be transmitted to a plurality of client devices at a predetermined time and is provided according to a schedule), the media guidance application also provides access to non-linear programming (e.g., content accessible to a client device at any time and is not provided according to a schedule). Non-linear programming may include content from different content sources including on-demand content (e.g., VOD), Internet content (e.g., streaming media, downloadable media, etc.), locally stored content (e.g., content stored on any client device described above or other storage device), or other time-independent content. On-demand content may include movies or any other content provided by a particular content provider (e.g., HBO On Demand providing “The Sopranos” and “Curb Your Enthusiasm”). HBO ON DEMAND is a service mark owned by Time Warner Company L.P. et al. and THE SOPRANOS and CURB YOUR ENTHUSIASM are trademarks owned by the Home Box Office, Inc. Internet content may include web events, such as a chat session or Webcast, or content available on-demand as streaming content or downloadable content through an Internet web site or other Internet access (e.g., FTP).
Grid 102 may provide media guidance data for non-linear programming including on-demand listing 114, recorded content listing 116, and Internet content listing 118. A display combining media guidance data for content from different types of content sources is sometimes referred to as a “mixed-media” display. The various permutations of the types of media guidance data that may be displayed that are different than display 100 may be based on user selection or guidance application definition (e.g., a display of only recorded and broadcast listings, only on-demand and broadcast listings, etc.). As illustrated, listings 114, 116, and 118 are shown as spanning the entire time block displayed in grid 102 to indicate that selection of these listings may provide access to a display dedicated to on-demand listings, recorded listings, or Internet listings, respectively. In some embodiments, listings for these content types may be included directly in grid 102. Additional media guidance data may be displayed in response to the user selecting one of the navigational icons 120. Pressing an arrow key on a user input device may affect the display in a similar manner as selecting navigational icons 120.
Advertisement 124 may provide an advertisement for content that, depending on a viewer's access rights (e.g., for subscription programming), is currently available for viewing, will be available for viewing in the future, or may never become available for viewing, and may correspond to or be unrelated to one or more of the content listings in grid 102. Advertisement 124 may also be for products or services related or unrelated to the content displayed in grid 102. Advertisement 124 may be selectable and provide further information about content, provide information about a product or a service, enable purchasing of content, a product, or a service, provide content relating to the advertisement, etc. Advertisement 124 may be targeted based on a user's profile/preferences, monitored user activity, the type of display provided, or on other suitable targeted advertisement bases.
While advertisement 124 is shown as rectangular or banner shaped, advertisements may be provided in any suitable size, shape, and location in a guidance application display. For example, advertisement 124 may be provided as a rectangular shape that is horizontally adjacent to grid 102. This is sometimes referred to as a panel advertisement. In addition, advertisements may be overlaid over content or a guidance application display or embedded within a display. Advertisements may also include text, images, rotating images, video clips, or other types of content described above. Advertisements may be stored in a client device having a guidance application, in a database connected to the client, in a remote location (including streaming media servers), or on other storage means, or a combination of these locations. Providing advertisements in a media guidance application is discussed in greater detail in, for example, Knudson et al., U.S. Patent Application Publication No. 2003/0110499, filed Jan. 17, 2003; Ward, III et al. U.S. Pat. No. 6,756,997, issued Jun. 29, 2004; and Schein et al. U.S. Pat. No. 6,388,714, issued May 14, 2002, which are hereby incorporated by reference herein in their entireties. It will be appreciated that advertisements may be included in other media guidance application display screens of the embodiments described herein.
In an embodiment, display 200 of
As discussed above, the systems and methods of the present disclosure may be implemented in whole or in part by client 300 of
In client-server based embodiments, control circuitry 304 may include communications circuitry suitable for communicating with a guidance application server or other networks or servers. The instructions for carrying out the above mentioned functionality may be stored on the guidance application server. Communications circuitry may include a cable modem, an integrated services digital network (ISDN) modem, a digital subscriber line (DSL) modem, a telephone modem, Ethernet card, or a wireless modem for communications with other equipment, or any other suitable communications circuitry. Such communications may involve the Internet or any other suitable communications networks or paths (which is described in more detail in connection with
Memory may be an electronic storage device provided as storage 308 that is part of control circuitry 304. As referred to herein, the phrase “electronic storage device” or “storage device” should be understood to mean any device for storing electronic data, computer software, or firmware, such as random-access memory, read-only memory, hard drives, optical drives, digital video disc (DVD) recorders, compact disc (CD) recorders, BLU-RAY disc (BD) recorders, BLU-RAY 3D disc recorders, digital video recorders (DVR, sometimes called a personal video recorder, or PVR_), solid state devices, quantum storage devices, gaming consoles, gaming media, or any other suitable fixed or removable storage devices, and/or any combination of the same. Storage 308 may be used to store various types of content described herein as well as media guidance information, described above, and guidance application data, described above. Nonvolatile memory may also be used (e.g., to launch a boot-up routine and other instructions). Cloud-based storage, described in relation to
Control circuitry 304 may include video generating circuitry and tuning circuitry, such as one or more analog tuners, one or more MPEG-2 decoders or other digital decoding circuitry, high-definition tuners, or any other suitable tuning or video circuits or combinations of such circuits. Encoding circuitry (e.g., for converting over-the-air, analog, or digital signals to MPEG signals for storage) may also be provided. Control circuitry 304 may also include scaler circuitry for upconverting and downconverting content into the preferred output format of the client device 300. Circuitry 304 may also include digital-to-analog converter circuitry and analog-to-digital converter circuitry for converting between digital and analog signals. The tuning and encoding circuitry may be used by the client device to receive and to display, to play, or to record content. The tuning and encoding circuitry may also be used to receive guidance data. The circuitry described herein, including for example, the tuning, video generating, encoding, decoding, encrypting, decrypting, scaler, and analog/digital circuitry, may be implemented using software running on one or more general purpose or specialized processors. Multiple tuners may be provided to handle simultaneous tuning functions (e.g., watch and record functions, picture-in-picture (PIP) functions, multiple-tuner recording, etc.). If storage 308 is provided as a separate device from client device 300, the tuning and encoding circuitry (including multiple tuners) may be associated with storage 308.
The guidance application may be implemented using any suitable architecture. For example, it may be a stand-alone application wholly implemented on client device 300. In such an approach, instructions of the application are stored locally, and data for use by the application is downloaded on a periodic basis (e.g., from an out-of-band feed, from an Internet resource, or using another suitable approach). In some embodiments, the media guidance application is a client-server based application. Data for use by a thick or thin client implemented on client device 300 is retrieved on-demand by issuing requests to a server remote to the client device 300. In one example of a client-server based guidance application, control circuitry 304 runs a web browser that interprets web pages provided by a remote server.
In some embodiments, the media guidance application is downloaded and interpreted or otherwise run by an interpreter or virtual machine (run by control circuitry 304). In some embodiments, the guidance application may be encoded in the ETV Binary Interchange Format (EBIF), received by control circuitry 304 as part of a suitable feed, and interpreted by a user agent running on control circuitry 304. For example, the guidance application may be an EBIF application. In some embodiments, the guidance application may be defined by a series of JAVA-based files that are received and run by a local virtual machine or other suitable middleware executed by control circuitry 304. In some of such embodiments (e.g., those employing MPEG-2 or other digital media encoding schemes), the guidance application may be, for example, encoded and transmitted in an MPEG-2 object carousel with the MPEG audio and video packets of a program.
User television equipment 352 may include a set-top box, an integrated receiver decoder (IRD) for handling satellite television, a television set, a digital storage device, a DVD recorder, a video-cassette recorder (VCR), a local media server, or other user television equipment. One or more of these devices may be integrated into a single device, if desired. User computer equipment 354 may include a PC, a laptop, a tablet, a WebTV box, a personal computer television (PC/TV), a PC media server, a PC media center, or other user computer equipment. WEBTV is a trademark owned by Microsoft Corp. Wireless user communications device 356 may include PDAs, a mobile telephone, a portable video player, a portable music player, a portable gaming machine, or other wireless devices.
A client device utilizing at least some of the system features described above in connection with
In system 350, there is typically more than one of each type of client device but only one of each is shown in
In some embodiments, a client device (e.g., user television equipment 352, user computer equipment 354, wireless user communications device 356) may be referred to as a “second screen device.” For example, a second screen device may supplement content presented on a first client device. The content presented on the second screen device may be any suitable content that supplements the content presented on the first device. In some embodiments, the second screen device provides an interface for adjusting settings and display preferences of the first device. In some embodiments, the second screen device is configured for interacting with other second screen devices or for interacting with a social network. The second screen device can be located in the same room as the first device, a different room from the first device but in the same house or building, or in a different building from the first device.
The user may also set various settings to maintain consistent media guidance application settings across in-home devices and remote devices. Settings include those described herein, as well as channel and program favorites, programming preferences that the guidance application utilizes to make programming recommendations, display preferences, and other desirable guidance settings. For example, if a user sets a channel as a favorite on, for example, the web site www.allrovi.com on their personal computer at their office, the same channel would appear as a favorite on the user's in-home devices (e.g., user television equipment and user computer equipment) as well as the user's mobile devices, if desired. Therefore, changes made on one client device can change the guidance experience on another client device, regardless of whether they are the same or a different type of client device. In addition, the changes made may be based on settings input by a user, as well as user activity monitored by the guidance application.
Although communications paths are not drawn between client devices, these devices may communicate directly with each other via communication paths, such as those described above in connection with paths 358, 360, and 362, as well other short-range point-to-point communication paths, such as USB cables, IEEE 1394 cables, wireless paths (e.g., Bluetooth, infrared, IEEE 802-11x, etc.), or other short-range communication via wired or wireless paths. BLUETOOTH is a certification mark owned by Bluetooth SIG, INC. The client devices may also communicate with each other directly through an indirect path via communications network 364.
System 350 includes content source 366 and media guidance data source 358 coupled to communications network 364 via communication paths 370 and 372, respectively. Paths 370 and 372 may include any of the communication paths described above in connection with paths 358, 360, and 362. Communications with the content source 366 and media guidance data source 358 may be exchanged over one or more communications paths, but are shown as a single path in
Content source 366 may include one or more types of content distribution equipment including a television distribution facility, cable system headend, satellite distribution facility, programming sources (e.g., television broadcasters, such as NBC, ABC, HBO, etc.), intermediate distribution facilities and/or servers, Internet providers, on-demand media servers, and other content providers. NBC is a trademark owned by the National Broadcasting Company, Inc., ABC is a trademark owned by ABC, Inc., and HBO is a trademark owned by Home Box Office, Inc. Content source 366 may be the originator of content (e.g., a television broadcaster, a Webcast provider, etc.) or may not be the originator of content (e.g., an on-demand content provider, an Internet provider of content of broadcast programs for downloading, etc.). Content source 366 may include cable sources, satellite providers, on-demand providers, Internet providers, over-the-top content providers, or other providers of content. Content source 366 may also include a remote media server used to store different types of content (including video content selected by a user), in a location remote from any of the client devices. Systems and methods for remote storage of content, and providing remotely stored content to client devices are discussed in greater detail in connection with Ellis et al., U.S. Pat. No. 7,761,892, issued Jul. 20, 2010, which is hereby incorporated by reference herein in its entirety.
Media guidance data source 358 may provide media guidance data, such as the media guidance data described above. Media guidance application data may be provided to the client devices using any suitable approach. In some embodiments, the guidance application may be a stand-alone interactive television program guide that receives program guide data via a data feed (e.g., a continuous feed or trickle feed). Program schedule data and other guidance data may be provided to the client device on a television channel sideband, using an in-band digital signal, using an out-of-band digital signal, or by any other suitable data transmission technique. Program schedule data and other media guidance data may be provided to client devices on multiple analog or digital television channels.
In some embodiments, guidance data from media guidance data source 358 may be provided to users' equipment using a client-server approach. For example, a client device may pull media guidance data from a server, or a server may push media guidance data to a client device. In some embodiments, a guidance application client residing on the user's equipment may initiate sessions with source 358 to obtain guidance data when needed, e.g., when the guidance data is out of date or when the client device receives a request from the user to receive data. Media guidance may be provided to the client device with any suitable frequency (e.g., continuously, daily, a user-specified period of time, a system-specified period of time, in response to a request from a client device, etc.). Media guidance data source 358 may provide, to user equipment devices 352, 354, and 356, the media guidance application itself or software updates for the media guidance application.
Media guidance applications may be, for example, stand-alone applications implemented on client devices. In some embodiments, media guidance applications may be client-server applications where only the client resides on the client device. For example, media guidance applications may be implemented partially as a client application on control circuitry 304 of client device 300 and partially on a remote server as a server application (e.g., media guidance data source 358). The guidance application displays may be generated by the media guidance data source 358 and transmitted to the client devices. The media guidance data source 358 may also transmit data for storage on the client, which then generates the guidance application displays based on instructions processed by control circuitry.
Content and/or media guidance data delivered to client devices 374, such as user equipment devices 352, 354, and 356 may be over-the-top (OTT) content. OTT content delivery allows Internet-enabled user devices, including any client device described above, to receive content that is transferred over the Internet, including any content described above. OTT content is delivered via an Internet connection provided by an Internet service provider (ISP), but a third party distributes the content. The ISP may not be responsible for the viewing abilities, copyrights, or redistribution of the content, and may only transfer IP packets provided by the OTT content provider. Examples of OTT content providers include YOUTUBE, NETFLIX, and HULU, which provide audio and video via IP packets. OTT content providers may additionally or alternatively provide media guidance data described above. In addition to content and/or media guidance data, providers of OTT content can distribute media guidance applications (e.g., web-based applications or cloud-based applications), or the content can be displayed by media guidance applications stored on the client device.
Media guidance data source 358 may make asset cataloging or recommendation applications available to users. Such applications may be downloaded from media guidance data source 368 to a client device, or may be accessed remotely by a user. These applications, as well as other applications, features and tools, may be provided to users on a subscription basis or may be selectively downloaded or used for an additional fee. In an embodiment, media guidance data source 368 may serve as a repository for media asset data developed by users and/or third-parties, and as a distribution source for this data and related applications.
Media guidance system 350 is intended to illustrate a number of approaches, or network configurations, by which client devices and sources of content and guidance data may communicate with each other for the purpose of accessing content and providing media guidance. The embodiments described herein may be applied in any one or a subset of these approaches, or in a system employing other approaches for delivering content and providing media guidance. The following four approaches provide specific illustrations of the generalized example of
In one approach, client devices may communicate with each other within a home network. Client devices can communicate with each other directly via short-range point-to-point communication schemes described above, via indirect paths through a hub or other similar device provided on a home network, or via communications network 364. Each of the multiple individuals in a single home may operate different client devices on the home network. As a result, it may be desirable for various media guidance information or settings to be communicated between the different client devices. For example, it may be desirable for users to maintain consistent media guidance application settings on different client devices within a home network, as described in greater detail in Ellis et al., U.S. patent application Ser. No. No. 11/179,360, filed Jul. 11, 2005. Different types of client devices in a home network may also communicate with each other to transmit content. For example, a user may transmit content from user computer equipment to a portable video player or portable music player.
In a second approach, users may have multiple types of client devices by which they access content and obtain media guidance. For example, some users may have home networks that are accessed by in-home and mobile devices. Users may control in-home devices via a media guidance application implemented on a remote device. For example, users may access an online media guidance application on a website via a personal computer at their offices, or a mobile device such as a PDA or web-enabled mobile telephone. The user may set various settings (e.g., recordings, reminders, or other settings) on the online guidance application to control the user's in-home equipment. The online guide may control the user's equipment directly, or by communicating with a media guidance application on the user's in-home equipment. Various systems and methods for client devices communicating, where the client devices are in locations remote from each other, is discussed in, for example, Ellis et al., U.S. Pat. No. 8,046,801, issued Oct. 25, 2011, which is hereby incorporated by reference herein in its entirety.
In a third approach, users of client devices inside and outside a home can use their media guidance application to communicate directly with content source 366 to access content. Specifically, within a home, users of user television equipment 352 and user computer equipment 354 may access the media guidance application to navigate among and locate desirable content. Users may also access the media guidance application outside of the home using wireless user communications devices 356 to navigate among and locate desirable content.
In a fourth approach, client devices may operate in a cloud computing environment to access cloud services. In a cloud computing environment, various types of computing services for content sharing, storage or distribution (e.g., video sharing sites or social networking sites) are provided by a collection of network-accessible computing and storage resources, referred to as “the cloud.” For example, the cloud can include a collection of server computing devices, which may be located centrally or at distributed locations, that provide cloud-based services to various types of users and devices connected via a network such as the Internet via communications network 364. These cloud resources may include one or more content sources 366 and one or more media guidance data sources 358. In addition or in the alternative, the remote computing sites may include other client devices, such as user television equipment 352, user computer equipment 354, and wireless user communications device 356. For example, the other client devices may provide access to a stored copy of a video or a streamed video. In such embodiments, client devices may operate in a peer-to-peer manner without communicating with a central server.
The cloud provides access to services, such as content storage, content sharing, or social networking services, among other examples, as well as access to any content described above, for client devices. Services can be provided in the cloud through cloud computing service providers, or through other providers of online services. For example, the cloud-based services can include a content storage service, a content sharing site, a social networking site, or other services via which user-sourced content is distributed for viewing by others on connected devices. These cloud-based services may allow a client device to store content to the cloud and to receive content from the cloud rather than storing content locally and accessing locally-stored content.
A user may use various content capture devices, such as camcorders, digital cameras with video mode, audio recorders, mobile phones, and handheld computing devices, to record content. The user can upload content to a content storage service on the cloud either directly, for example, from user computer equipment 354 or wireless user communications device 356 having content capture feature. Alternatively, the user can first transfer the content to a client device, such as user computer equipment 354. The client device storing the content uploads the content to the cloud using a data transmission service on communications network 364. In some embodiments, the client device itself is a cloud resource, and other client devices can access the content directly from the client device on which the user stored the content.
Cloud resources may be accessed by a client device using, for example, a web browser, a media guidance application, a desktop application, a mobile application, and/or any combination of access applications or the same. The client device may be a cloud client that relies on cloud computing for application delivery, or the client device may have some functionality without access to cloud resources. For example, some applications running on the client device may be cloud applications, i.e., applications delivered as a service over the Internet, while other applications may be stored and run on the client device. In some embodiments, a client device may receive content from multiple cloud resources simultaneously. For example, a client device can stream audio from one cloud resource while downloading content from a second cloud resource. Or, a client device can download content from multiple cloud resources for more efficient downloading. In some embodiments, client devices can use cloud resources for processing operations such as the processing operations performed by processing circuitry described in relation to

The system of claim 14, wherein the first and second records represent a common content element, and storing an association between the first and second data records comprises storing the metadata of the first data record and the metadata of the second data record as metadata of a common data record for the common content element.
16. The system of claim 14, wherein storing an association between the first and second data records comprises storing the metadata of the second data record as metadata of the first data record in the database of records.
17. The system of claim 13, wherein the second processor is included in a client device, and storing an association between at least some of the seed information and the second record comprises displaying some of the metadata of the second record at the client device.
18. The system of claim 12, wherein each token in the database of tokens is also associated with an operative expression.
19. The system of claim 18, wherein determining that the seed information, including the matching token, corresponds to metadata of a first data record comprises:
- generating, with the processor, a query based on at least some of the seed information and the operative expression associated with the token; and
- with the processor, searching the database of data records using the query.
20. The system of claim 12, wherein the content domain is music and the token comprises at least one of: feat, with, and duet.
21. The system of claim 12, wherein the seed information comprises a text string.
22. The system of claim 12, wherein the seed information comprises at least one of an image and a sound.
23. A system for searching metadata based on seed information, comprising:
- means for receiving seed information from a processor;
- means for accessing a database of tokens stored in a memory device, each token associated with a content domain and each content domain associated with two or more tokens;
- means for determining whether a portion of the seed information matches a token in the database of tokens;
- means for identifying, in response to determining that a portion of the seed information matches a token, the content domain associated with the matching token;
- means for accessing a database of data records for content elements within the identified content domain, each record including metadata descriptive of a content domain;
- means for determining that the seed information, including the matching token, corresponds to metadata of a first data record in the database of data records; and
- means for transmitting, to the second processor, an identifier of the first data record.
24. The system of claim 23, further comprising:
- means for storing an association between at least some of the seed information and the first data record, in response to determining that the seed information, including the matching token, corresponds to metadata of a first data record.
25. The system of claim 24, wherein the seed information is metadata of a second data record stored in a database accessible by the second processor, and storing an association between at least some of the seed information and the second record comprises storing an association between the first and second data records.
26. The system of claim 25, wherein the first and second records represent a common content element, and storing an association between the first and second data records comprises storing the metadata of the first data record and the metadata of the second data record as metadata of a common data record for the common content element content elementcontent element.
27. The system of claim 25, wherein storing an association between the first and second data records comprises storing the metadata of the second data record as metadata of the first data record in the database of records.
28. The system of claim 24, wherein the second processor is included in a client device, and storing an association between at least some of the seed information and the second record comprises displaying some of the metadata of the second record at the client device.
29. The system of claim 23, wherein each token in the database of tokens is also associated with an operative expression.
30. The system of claim 29, wherein the means for determining that the seed information, including the matching token, corresponds to metadata of a first data record in the database of data records comprises:
- means for generating a query based on at least some of the seed information and the operative expression associated with the token, in response to determining that a portion of the seed information matches a token; and
- means for searching a database of data records using the query.
31. The system of claim 23, wherein the content domain is music and the token comprises at least one of: feat, with, and duet.
32. The system of claim 23, wherein the seed information comprises a text string.
