experiments using three types of real networks assembled from blog trackbacks,
word associations and Wikipedia references, we demonstrated that the k -dense
method could extract communities almost as eciently as the k -core method,
while the qualities of the extracted communities are comparable to those ob-
tained by the k -clique method. we plan to perform more extensive experiments
using a wider variety of networks in order to clarify relative strength and weak-
ness of the k -dense method.
