Web document clustering using hyperlink structures

With the exponential growth of information on the World Wide Web, there is great demand for developing e.cient methods for e/ectively organizing the large amount of retrieved information. Document clustering plays an important role in information retrieval and taxonomy management for the Web. In this paper we examine three clustering methods: K-means, multi-level METIS, and the recently developed normalized-cut method using a new approach of combining textual information, hyperlink structure and co-citation relations into a single similarity metric. We found the normalized-cut method with the new similarity metric is particularly e/ective, as demonstrated on three datasets of web query results. We also explore some theoretical connections between the normalized-cut method and the K-means method. c © 2002 Elsevier Science B.V. All rights reserved.
