Newsgroup Clustering Based On User Behavior - A Recommendation Algebra

Abstract

User models are a tool for guiding system behavior in interactive systems, and their utility and properties, desirable and undesirable, have been investigated in this context. There are several ways of utilizing information about the user that have NOT been implemented, however. In this paper a scheme for users to peek at other users' user models to extract information is proposed, in an information retrieval or information filtering domain. The material used for the study is a set of .newsrc files.
