Abstract

The key to effective information filtering is user profiling - the ability to represent and reason about the interests or preferences of a user. This paper briefly surveys techniques for filtering the vast amount of information that is now available on the Internet and other electronic sources, in a variety of media. The non-explicit social information filtering approach is then examined in more detail and a new algorithm proposed which compares favourably with earlier approaches.
