Many studies on the Web graph concentrate on the graph structure, and do not consider textual properties of the nodes. The authors propose that a topic taxonomy such as Yahoo or ODP provides a useful framework for understanding the structure of content-based clusters and communities, and they present measurements that may prove valuable in the design of community-specific crawlers and link-based ranking systems. The experiments are based on ODP data.
