Abstract: A method and computer-executable program is disclosed for graphically rendering information of a database which can be arranged in form of a table, and for extraction associations between database records. An element and/or an arithmetic expression computed from the records in the database can be associated with a graphic representation consisting of instructions, such as setting a fill color, drawing a rectangle, and so on. Graphic renditions can include tables, histograms, bar charts, timeline displays, pie charts, and tree maps, as well as combinations of such displays. The proposed visualization-rendering method is flexible and computationally fast, since at most O(N) graphic instructions need to be generated for a database of N records.

Abstract: A method and system for context based searching of category wise arranged electronic catalog database is provided. The confidence value for each of the retrieved categories is displayed graphically as an indication of the relevance of that category. The percentage impact of each of the query terms on the search result is also shown in a graphical format. Various search strategies and algorithms are used and the output is ranked according to the user relevance. The system is intelligent in the sense that it suggests user with spellings, uses word morphing, synonymous words to user query etc. The user can define weightage to be given to various attributes and also refine his search by searching in particular segments.

Abstract: A location-code system provides user-specific location codes corresponding to locations. A user can provision the codes. When the user accesses a location-based service, the user can then provide the service with a location code. The service, perhaps with the assistance of a location-code provider, can then translate the user-specific location code into location coordinates that can be used to facilitate a location-based service. Further, the location-code system can provide global, or generic, location-codes for particular locations, which any user can use as a basis to indicate a location.

Abstract: The present invention provides a system and technique for initiating, conducting, and managing real-time surveys, in the context of a real-time discourse, such as Internet chat, to provide dynamic, real-time survey results. A surveyor initiates a survey by filling out an electronic form which is processed and submitted to a sorting component of the invention. The invention imposes an additional layer of functionality upon a Live Information Selection and Analysis tool which gathers, summarizes, and indexes chat messages in a real-time discourse. The sorting component matches the collected real-time chat messages from the LISA tool with correlating submitted survey queries to provide raw real-time survey results which are converted into a viewable format for submission to the surveyor. The present invention makes it possible to initiate, conduct, and manage multiple surveys simultaneously to provide accurate, dynamic, real-time survey results within the context of a real-time discourse.

Abstract: There is proposed a technique for counting channels at a node of a multi-channel optical network, where the node is connected to a following node and a preceding node by an optical communication line carrying a plurality of information optical channels. The technique comprises exchanging of information structures between the nodes, such that each of the information structures specifies particular optical information channels which are currently in use at a predetermined network section or node.

Abstract: Searching and matching a set of query strings used for accessing information in a database directory. In this disclosure, a user community administration tool queries a database directory containing user information associated with a user community. In the user community administration tool, there is an input query generation component that generates an input query having a search pattern that includes a combination of attribute names, logical, operators and attribute values. An accessing component accesses a library of queries used for accessing the user information in the database directory. A partitioning component partitions each of the queries in the library into logical units. Each logical unit comprises a combination of an attribute name, logical operator and attribute value. A comparing component compares the search pattern of the input query to each partitioned logical unit for each of the queries in the library.

Abstract: Systems and methods for scoping a search. When a content index for electronic data is built, one or more scope restrictions are included in the content index. The scope restriction may be, for example, a root folder identifier, a mailbox identifier, or a URL. Because the scope restriction is included in the content index random access of the property store to determine the scope is avoided. Rather, the scope restriction is implicitly added to a search that uses the content index. By including a scope restriction in the search query, the search results identified from the content index are limited to results that match the scope restriction. Advantageously, the effect of including the scope restriction in the search is ignored if the search results are relatively small or when including the scope restriction provides little benefit.

Abstract: An apparatus and method for providing access rights information on computer accessible content are provided. The apparatus and method provide a mechanism through which access rights information is provided in association with information and content such that use of the information and content is controlled based on the access rights information. The apparatus and method include access rights information tags being associated with information and content. A web browser is provided with code, either in the web browser, or as a plugin application or browser extension, to process the access rights information and thereby control the usage of the associated information and content. In addition to being implemented as tags, the access rights information may be inserted into a file such as in the file header. In such an embodiment, the file header includes a pointer to the file data and thus, the inclusion of the access rights information into the file header does not disrupt the processing of the file.

Abstract: Techniques for replicating a database object of a relational database managed by a database system from a first node on a network to a second node on the network include determining that the database object on the first node includes a user-defined object. A first routine of the database system is invoked. The first routine performs the step of copying the database object to the second node of the network. The first routine copies a name of a user-defined defined type of the user-defined object from the first node to the second node. The first routine also copies a first definition of the user-defined type from the first node to the second node. The first routine then copies a second definition of the database object from the first node to the second node. The second definition includes the name of the user-defined type. These techniques provide the benefits of peer-to-peer replication in a distributed database to users of object-relational databases that including user-defined objects.

Abstract: A method of clustering data includes choosing an initial cluster point and proximate data points from a set of data points. A revised data set is defined that excludes the initial cluster point and the proximate data points. A cluster point relatively far from the selected cluster point is selected. A revised data set excluding the selected cluster points and proximate data points is then defined. A decision is made whether to choose another cluster point. If so, a cluster point relatively far from the selected cluster points is selected and a revised data set excluding the selected cluster points and corresponding proximate data points is defined. If another cluster point is not to be selected, a final cluster point is chosen within the revised data set. The final cluster point is relatively far from the previously selected cluster points. The selected cluster points are then used to initiate a cluster analysis.

Abstract: A method for querying metadata associated with media, such as multimedia and/or streaming media, on a computer network includes separating the metadata into keywords. The keywords are compared with valid keywords. A score is calculated in accordance with the degree of similarity between the keywords and valid keywords. If the degree of similarity is above a threshold, the metadata is qualified as valid metadata. Valid metadata is available for comparison and correction of other (invalid) metadata.

Abstract: A method and apparatus for implicitly partitioning the storage space available on a storage medium, to a storage medium for storing user data and to a recording device for storing user data on a storage medium. In order to limit the mount/unmount time of a volume like a UDF volume on a magnetic tape for ADR and to limit overall seek times during reading: a) storage space available for storage on the medium is divided into a directory region and a data region, b) metadata are stored in the directory region, c) user data are stored in the data region being implicitly subdivided into data sub-regions, d) file set data for user data stored in a data sub-region are stored in a corresponding directory sub-region being assigned to this data sub-region, and e) borders and size of data sub-regions are variable.

Abstract: This invention automates the most common processes in market research study design and analysis. By combining a database framework designed to hold all the data elements used in a market research survey, codifying heuristics actually used by analysts to make decisions about survey analysis, and building a lexicon to communicate summary results to lay readers. First, this provides a stringent framework for designing a questionnaire and study plan which will lead to clear tab plans and analysis plans. Second, by automating the research design and analysis process, it eliminates the human error associated with the intricacies of questionnaire design, tab plan design, and research report writing. Thirdly, it also greatly reduces the time necessary to rerun an entire report based on simple changes to any study element definitions to a few hours, a process formerly taking days or weeks.
