Graph-Theoretic Nature of Local Web-Spaces

A local Web-space is defined as a sub-graph of WWW whose sites are confined within a particular geographical area. It is naturally conjectured that sites in a local Web-space are tightly connected with each other by means of links because of their geographical, social and human relations. The initial motivation of this paper is to examine the conjecture. In fact, this paper gauges the strength of connection among sites in a local Web-space by plural graph-theoretic metrics. The result is the contrary and reveals that sites in a local Web-space are weakly connected with each other and the concentration to "hub" sites is relatively weak
