  • Community Extraction Method of Road Networks Based on Betweenness Contribution  [in Japanese]

    Fushimi Takayasu , Saito Kazumi , Ikeda Tetsuo , Kazama Kazuhiro

    … To this end, based on a notion of group-betweenness centrality measure, we newly formalize this problem as a k-betweens problem and propose a community extraction method of road networks to identify the influential zones. … Furthermore, by computing the degree of antagonism among communities using the entropy of betweenness contribution rates, we can quantify the effectiveness of installing the same signboards for residents of areas where the influential zones of multiple signboards overlap.</p> …
