The growing popularity of Web based social networks has given rise to the need to build
trust communities
that inspire members to share their experiences, feelings and opinions in an open and honest way. In this paper, we propose a framework for building trust communities in social networks using
social trust
. We first introduce the concept of social trust and social capital, and describe the role they play in building trust communities. We then define a
social trust model
for social networks and the corresponding
recommender system
for building trust communities in social networks. The novel idea behind our social trust model is that we introduce the concept of
engagement trust
and combine it with
popularity trust
to derive a
social trust
of the community as well as of individual members in the community.
