| Abstract | Current approaches to information retrieval over the Web are based on a scenario in which the user enters a query to a search engine. The query is then used by the engine to retrieve a set of documents that best match the query. Using the context to guide the search constitutes a considerable algorithmic challenge. One needs to find ways to extract the amount of context which optimizes the information retrieved, as well as to devise adequate ways to use the extracted context for focusing the response to the user's query. This thesis proposes the basic setting of the search scenario by introducing context as an additional input of the search process. In this scenario, when the user marks an expression in a document and submits it for search, the system captures the context surrounding the expression, and utilizes it to yield focused results. |
