A Practical Clustering Algorithm for Static and Dynamic Information Organization \Lambda
 

Summary: A Practical Clustering Algorithm
for Static and Dynamic Information Organization \Lambda

Abstract
We present and analyze the off­line star algorithm for clus­
tering static information systems and the on­line star algo­
rithm for clustering dynamic information systems. These
algorithms organize a document collection into a number of
clusters that is naturally induced by the collection via a com­
putationally efficient cover by dense subgraphs. We further
show a lower bound on the accuracy of the clusters produced
by these algorithms as well as demonstrate that these algo­
rithms are efficient (running times roughly linear in the size
of the problem). Finally, we provide data from a number of
experiments.
1 Introduction
We wish to create more versatile information capture
and access systems for digital libraries by using infor­
mation organization: thousands of electronic documents
