A survey of implicit trust on social networks

Social Networking analysis has recently gained a lot of research interest because of social media like twitter, facebook, blogs or customer review sites. The emerging online environment let people buy and sell goods, play and recommend product to others without knowing the remote partner. In real life, we come to know about others reputation through our social circle. However, it is not always sufficient to depend completely on public opinion, therefore a trust measure is required to give personalized view. Trust is becoming an essential parameter in online environment for recommendation of useful content. Although a majority of social network research deals with explicit trust, however we believe that implicit trust plays a significant role in the overall dynamics of social networks. In this paper, we propose a framework for handling trust in social network which is based on the implicit behavior of the users.
