Information presentation based on individual user interests

Abstract

We propose a method for presenting information based on individual user interests and knowledge. In previous work on recommending information, such as through WWW pages, the user could not always get his/her needed information, since the user's interests were represented only in keywords or key categories, and the contents of the presented information were previously formed by the information presenter; consequently, this information did not necessarily match the user's interests and knowledge. In the proposed method, the system acquires the user's implicit and/or explicit interests and knowledge from a question-and-answer interaction and presents the user with focus-of-interest information based on them. For personalizing the presentation and recommendation of information, the system provides each user with an information retriever using the user's operation records, a personal conceptual space, and control knowledge.
