Abstract: A system, method, and computer program product are provided for determining information associated with an extracted portion of content. In use, a user is identified. Additionally, content generated by the user is identified. Additionally, a portion of the content is extracted. Further, information associated with the extracted portion of the content is determined. Further still, the determined information is added to a profile of the user. Also, an action is initiated, based on the profile of the user.

Abstract: In an information retrieval method a meta search engine receives a user information query in the form of key words; and submits the query to a search engine, and also submits the query to a snippet database storing previously selected results, indexed by a snippet index of terms included in snippets of the results when they were previously selected. The meta search engine then receives results from the search engine; and receives a response from the snippet database. It merges the results from the search engine with those from the snippet database; and submits re-ranked results to the user. The snippet database processes in parallel with the underlying search engine. The meta search engine also monitors which results of the returned re-ranked results are selected by the user, and updates the snippet index accordingly.

Abstract: In an information retrieval method a meta search engine (4) receives a user information query (qT) in the form of key words; and submits the query to a search engine (2), and also submits the query to a snippet database (6) storing previously selected results, indexed by a snippet index of terms included in snippets of the results when they were previously selected. The meta search engine (4) then receives results from the search engine (2); and receives a response from the snippet database (6). It merges the results from the search engine (2) with those from the snippet database (6); and submits re-ranked results to the user. The snippet database (5, 6) processes in parallel with the underlying search engine (2). The meta search engine (4) also monitors which results of the returned re-ranked results are selected by the user, and updates the snippet index accordingly.
