Algorithms and Models for the Web-Graph

This book contains the revised papers of the Fourth International Workshop on Algorithms and Models for the Web-Graph. It covers a wide range of topics in the study of the Web-graph such as algorithms, PageRank analysis and computational as well as clustering.

The World Wide Web has become part of our everyday life and information retrieval and data mining on the Web are now of enormous practical interest. The algorithms supporting these activities combine the view of the Web as a text repository and as a graph, induced in various ways by links among pages, links among hosts, or other similar networks. The aim of the 4th Workshop on Algorithms and Models for the Web-Graph (WAW 2006)wasto further the understanding of these Web-induced graphsand stimulate the developmentofhigh-performancealgorithmsandapplicationsthat use the graph structure of the Web. The workshop was meant both to foster an exchange of ideas among the diverse set of researchers already involved in this topic and to act as an introduction for the larger community to the state of the art in this area. The workshop program included invited keynote talks by Fan Chung-Graham (UCSD), Soumen Chakrabarti (IITB), Walter Willinger (ATT Research) and Filippo Menczer (Indiana).

Klappentext
This book constitutes the revised papers of the Fourth International Workshop on Algorithms and Models for the Web-Graph, WAW 2006, held in Banff, Canada, November 30 - December 1, 2006. The 12 revised full papers and 3 posters presented were carefully reviewed and selected from 28 submissions for inclusion in the book. The papers address a wide variety of topics related to the study of the Web-graph such as algorithms for the Web-graph, PageRank analysis and computational as well as clustering.
