Abstract:
The graph structures of three national university publicly indexable Webs
from Australia, New Zealand, and the UK were analyzed. Strong scale-free
regularities for page indegrees, outdegrees, and connected component sizes
were in evidence, resulting in power laws similar to those previously
identified for individual university Web sites and for the AltaVista-indexed
Web. Anomalies were also discovered in most distributions and were tracked
down to root causes. As a result, resource driven Web sites and
automatically generated pages were identified as representing a significant
break from the assumptions of previous power law models. It follows that
attempts to track average Web linking behavior would benefit from using
techniques to minimize or eliminate the impact of such anomalies.
