Clustering on the Web

The need to employ various clustering methodologies and practices on the Web increases, due to the exponential growth of data and users interactions over the Internet. Earlier research efforts have focused both on understanding the Web user needs and on organizing web data sources (e.g. pages, documents).
- Clustering methodologies have been proven beneficial in terms of grouping Web users in clusters such that the various information circulation activities can be facilitated. More specifically, similarity measures have been proposed towards capturing Web users common practices whereas effective Web user logs processing has resulted in the definition of user session patterns. Knowledge about such commonalities/differences between users facilitates procedures employed in various fields such as e-commerce, dissemination of information etc.
- Various approaches for Clustering of Web sources have been proposed since the number of web sources has been increasing rapidly. In this context, the idea of compound documents and logical information units has been quite evolving recently. Moreover, the notion of Web page communities has gain ground lately in order to organize web sources and meet web user requirements. This talk will overview the most popular methodologies and implementations in terms of clustering either Web users or Web sources and will present a survey about current status and future trends in clustering employed over the Web.

Athena I. Vakali received a B.Sc. degree in Mathematics from the Aristotle University of Thessaloniki, Greece, a M.Sc. degree in Computer Science from Purdue University, USA (with a Fulbright scholarship) and a Ph.D. degree in Computer Science from the Department of Informatics at the Aristotle University of Thessaloniki. Since 1997, she is a faculty member of the Department of Informatics, Aristotle University of Thessaloniki, Greece. Her research interests include Web data management, focusing on the performance and analysis of Web (as well as XML) data storage, caching and clustering.
