The TREC-6 filtering track : Description and analysis
David A. Hull · 1997
This article describes the experiments conducted in the TREC-7 filtering track, which consisted of three subtasks: adaptive filtering, batch filtering, and routing. The focus this year is on adaptive filtering, where the system begins with only the topic statement and must interactively adjust a filtering profile constructed from that topic in response to on-line feedback.
