Link prediction in social network: a fuzzy approach

Thakur GS, Yachana Bhawsar

Link prediction in Social Network is an open and challenging problem which has been studied intensively in recent years. There are lots of algorithms available for link prediction. In this paper we applied fuzzy soft concept to predict link in a given social network. Effective methods for link prediction could be used to analyze such a social network to suggest promising interactions or collaborations that have not yet been identified within organization.
