We therefore introduce a news video retrieval system called NewsBoy which captures the users' implicit interactions with its graphical interface, extracts terms from visited video documents and stores them in user pro?les. The terms are weighted based on the type of implicit feedback, multiple interests are identi?ed by clustering the content of the profile. In this paper, we describe the architecture of the system and introduce our approach of adding the ostensive factor to capture the users' evolving interest. Preliminary results show the acceptance of the system and highlight drawbacks.</ABSTRACT><URL>http://persdb08.stanford.edu/7-PersDB-Paper.pdf</URL></RECORD></RECORDS></XML>
