The results for a given query are identical, independent of the user, or the context in which the user made the request. An approach is demonstrated that explores implicit contexts as obtained from a document the user is reading. The approach inserts into an original (web) document functionality to directly activate context driven queries that yield related articles obtained from various information sources. http://repub.eur.nl/res/pub/9537/ 2000-01-01T00:00:00Z In this paper we describe an approach to respond to a request for information with the identification and location of the appropriate person as a source of information for answering the question. The expertise of a person is characterized using a weighted profile that has been derived from a series of documents describing the expert's activities. Having these profiles, requests for information can be matched with these profiles. The best matches correspond with the people that are experts for providing information on the request.
