Abstract: A method to monetize multimedia queries is provided. The method includes receiving a multimedia query from a client device. In response, to the multimedia query a collection of thumbnails representing multimedia files is created. Position information for advertisement information is generated based on multimedia content included in the multimedia files. The position information specifies where the advertisement information should be displayed. Accordingly, advertisement information associated with advertisers that pay above a specified threshold is displayed with thumbnails of the multimedia content or with the actual multimedia content.

Abstract: A method and media are provided for managing feedback data that will be used for ranking search results. A plurality of user feedback data from more than one user can be aggregated into a search index. The user feedback data can be associated with one or more documents within the index such that the one or more documents can be ranked based on the type of feedback data that is aggregated. Once the documents have been ranked, the ranked documents can be provided to a requester.

Abstract: The invention discloses a system and method for managing feedback data that will be used for ranking search results. The invention can aggregate a plurality of user feedback data from more than one user into a search index. The user feedback data can be associated with one or more documents within the index such that the one or more documents can be ranked based on the type of feedback data that is aggregated. Once the documents have been ranked, the ranked documents can be provided to a requester.

Abstract: A system and method for formulating a related content query are provided. A search engine receives queries having terms for content items and stores the queries and user interaction data in a query log. Also, the search engine provides a collection of content items and related content item queries for each content item within the collection of content items, in response the queries. Each content item in the collection of content items includes terms that match the received queries. The related content item queries are generated by an advisor engine that processes the query log and each content item in the collection of content items to select query terms, different from the received query terms, which previously resulted in a specified content item being accessed or selected.

Abstract: A system, method, and computer-readable media are disclosed for providing images in a ranked order. The system can include an aggregation component for aggregating a plurality of images with corresponding text. Additionally, the system can include a name detector a name detector for detecting names within a search query. Moreover, the system can include a ranking component for ranking the aggregated images based on whether the name detector detects a name.
