Patent number: 9177045Abstract: Topical search engines can add contextual keywords to an input query to bias results toward a particular topic or domain. In one instance, query context models can be constructed to facilitate topical search. Upon receipt of one or more topic-relevant sites, a plurality of topical queries can identified automatically. Contextual keywords can be identified with respect to the plurality of topical queries as a function of lexical generality, among other things. Subsequently, a query context model, comprising the identified topical queries and related contextual keywords, can be employed to restrict query results to a particular topic.Type: GrantFiled: June 2, 2010Date of Patent: November 3, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Raman Chandrasekar, Parikshit Sondhi, Robert Rounthwaite

Patent number: 8285706Abstract: Human computation games are provided wherein a player is shown a page, such as a web page. The player is then asked to provide one or more terms that are intended to cause a search engine to return the page in response to performing a query using the terms. The terms provided by the player during game play are then collected, stored, and utilized to improve the performance of the search engine.Type: GrantFiled: June 10, 2009Date of Patent: October 9, 2012Assignee: Microsoft CorporationInventors: Raman Chandrasekar, Christopher Brian Quirk, Sarthak Deepak Shah, Matthew Richardson, Christopher John Champness Burges, Abhishek Gupta, Hao Ma

Publication number: 20120185457Abstract: Domain specific topics, and optionally uniform resource locators (URLs) can be received from a user, and from those domain specific topics and URLs, domain tuned search definitions are generated for a given domain. The domain tuned search definitions are saved and the user is provided with a definition of a domain tuned search interface that is embedded on a site specified by the user. When someone reviewing the user's web site performs a search using the domain tuned, embedded search interface, a search engine is invoked which performs a search on the user's input query, and then returns domain specific search results. The search engine searches for domain specific search results over web sites in addition to the web site that the user is currently reviewing, so the search is more precise than a general web search but broader than a specific site search.Type: ApplicationFiled: March 27, 2012Publication date: July 19, 2012Applicant: Microsoft CorporationInventors: Raman Chandrasekar, Dean A.

Patent number: 8191004Abstract: A user interface display for software has a user satisfaction portion displayed on each page. The user satisfaction portion includes a user selectable element which allows a user to provide a user satisfaction score (or level) with a single mouse click. In response to receiving the user satisfaction level, the context of the software which the user is using is recorded, and the user satisfaction level is correlated to that context. The captured data can be provided to application designers and developers directly or via computed metrics.Type: GrantFiled: August 6, 2008Date of Patent: May 29, 2012Assignee: Microsoft CorporationInventors: Raman Chandrasekar, Dean A.

Patent number: 8086591Abstract: The claimed subject matter provides systems and/or techniques that effectuate combining domain-tuned search systems. The system can include mechanisms that obtain queries, written descriptions, or illustrative web-pages regarding a particular area of interest, and generate a definition related to the area of interest. The definition contains a list of paths with associated weights employed to identify an pre-established first domain-tuned search system related to the area of interest. The first domain-tuned search system thereafter can be combined with a second domain-tuned search system related to another area of interest and presented to a user for utilization in re-ranking generic search results to be specific to the first and second domains of interest if combined, or to only the first domain if weights for the second domain are logically subtracted.Type: GrantFiled: May 30, 2008Date of Patent: December 27, 2011Assignee: Microsoft CorporationInventors: Matthew R.

Publication number: 20110276390Abstract: This patent application pertains to selecting advertisements for presentation with search results. One example includes receiving a user's search query. This example also includes selecting an advertisement that is relevant for presentation to the user with search results for the search query. The advertisement is selected from a set of advertisements by comparing a semantic context of individual advertisements to a semantic context of the user's search query.Type: ApplicationFiled: May 6, 2010Publication date: November 10, 2011Applicant: Microsoft CorporationInventors: Xiaolei Li, Raman Chandrasekar, Dou Shen

Publication number: 20110040751Abstract: An information dissemination system ranks the search results based on a temporal weight assigned to each search result. The temporal weight is an indication of the importance to a user that varies with time. For each search result, the information dissemination system calculates a temporal weight that is based on the temporal proximity of the event that is related to the search result. The temporal weight may be used to re-rank the search results.Type: ApplicationFiled: October 25, 2010Publication date: February 17, 2011Applicant: Microsoft CorporationInventors: Raman Chandrasekar, Dean A.

Patent number: 7756864Abstract: A search and a browse on a single user query is performed. A refined query is selected from the results of the first user query. Thereafter, a list of concepts from a first directory associated with the refined query is obtained. The concepts are defined in a hierarchical relationship with concepts having broader scope being higher in the hierarchy and concepts having a narrower scope being lower in the hierarchy. Additionally, a list of web sites associated with the search concept is obtained from a second directory.Type: GrantFiled: November 14, 2005Date of Patent: July 13, 2010Assignee: Microsoft CorporationInventors: Raman Chandrasekar, James Charles Finger, II, Sally K.

Publication number: 20100088390Abstract: Described is a technology that uses a web service as a proxy for transferring data between mobile communications devices. A short range communication link is established between a source device and a destination device. The source device sends a content identifier over the short range communication link to the destination device, that the destination devices uses to access the content, including when the short range communication link no longer exists. Also described is security for the content via authentication data (e.g., credentials) and policy associated with the content to control its access. The source device may select the destination device or may broadcast the content identifier to any number of destination devices within range.Type: ApplicationFiled: October 3, 2008Publication date: April 8, 2010Applicant: MICROSOFT CORPORATIONInventors: Tian Bai, Eric I-Chao Chang, Raman Chandrasekar, Michael Ying-Kee Tsang

Patent number: 7685199Abstract: An information dissemination system provides users information related to topics extracted from event classes. Event classes can generally be thought of as scripts that specify topics and actions for obtaining information related to the topics. The event classes are executed to obtain information related to the particular event class. The information dissemination system identifies a user event that is of interest to a user. The information dissemination system then identifies an event class that corresponds to the user event. The information dissemination system then performs the actions specified for the event class, obtains the action results, and renders the action results to the user.Type: GrantFiled: July 31, 2006Date of Patent: March 23, 2010Assignee: Microsoft CorporationInventors: Raman Chandrasekar, Dean A.

Publication number: 20100057675Abstract: A component presents access to a recommended search provider via a user interface element. In an example embodiment, a device-implemented method for recommending a search provider includes acts of receiving, ascertaining, and modifying. A search query input is received. A recommended search provider is ascertained at least partially responsive to the search query input. A user interface is modified to indicate the recommended search provider.Type: ApplicationFiled: August 27, 2008Publication date: March 4, 2010Applicant: MICROSOFT CORPORATIONInventors: Ryen W.
