Identification of Protein Complexes in PPI Networks by a Fuzzy Method

In this paper, we introduce a novel fuzzy method which is combined fuzzy relation, interaction probability values and hub structure to detect sub-communities in complex networks. We apply our method on yeast proteinprotein interaction network to identify the protein complexes. Compared with traditional method, more protein complexes have been identified by this new fuzzy method. Meanwhile, we evaluate our method on two real social networks. The experimental results show that our method works well and give a reasonable understanding of these communities.
