Abstract

Thelwall and Wilkinson use crawls of university web sites in the UK, Australia, and New Zealand to generate all links targeted at same country university web sites which they then use to create a graph structure for study. Using Broder's study as a model they identify a strongly connected component, SCC, where one could start anywhere in the set and reach every other page, and an Out component whose pages can be reached from all strongly connected pages but provide no link back to that set. The other components in the Broder model are not accessible except with access to a major search engine database. In link and out link counts for all three university systems in both the Out and SCC components when graphed logarithmically display the linear nature which would indicate that power laws, and a success breeds success phenomena, are generally in effect. However, automatically generated pages, non-HTML web pages, and large resource-driven sites all were associated with anomalies in this observation.
