In this paper we present a system for static and
dynamic information organization and show our eval-
uations of this system on TREC data. We intro-
duce the off-line and on-line star clustering algorithms
for information organization. Our evaluation exper-
iments show that the off-line star algorithm outper-
forms the single link and average link clustering algo-
rithms. Since the star algorithm is also highly efficient
and simple to implement, we advocate its use for tasks
that require clustering, such as information organiza-
tion, browsing, filtering, routing, topic tracking, and
new topic detection.
