A Research on Connectivity of Undirected Basic Element Complex Network of Topic-Related Documents

A research on the connectivity of undirected version Basic Element complex network generated from topic-related document set is carried out. Key properties of the network are obtained. The networks are mainly connected except some components involving very small ratio of nodes of the whole network. And the key semantic units do not exist in these small components. The properties will simplify the work if network methods are taken to address some nature language processing tasks.
