Abstract :
It is important for us to estimate centrality degree of terrorist networks. In this paper, a novel method was presented by us to evaluate terrorism network centrality nodes. The algorithm is based on network cohesion degree measures used in social network analysis. The advantage of this method is to be considered both degree and position of a node. The experimental results show that this method of efficiency has some advantage over betweenness centrality method.
