Identifying cliques in dark web forums - An agglomerative clustering approach

Tarique Anwar, Muhammad Abulaish
2012 2012 IEEE International Conference on Intelligence and Security Informatics  
In this paper, we present a novel agglomerative clustering method to identify cliques in dark Web forums.  ...  The similarity function is employed in the proposed clustering algorithm to group threads into different clusters that are finally presented as individual cliques.  ...  In this paper, we present an agglomerative clustering method to deduce different cliques of a dark Web forum.  ...
