An appraisal mechanism for social marketplace

Social network platforms have been so popularized that they are to be indispensable to daily life. In recent years, the electronic commerce marketplace faces the problems: like searching for product providers and trust issues of product providers. People are used to deal with the guy they are familiar with and more believe their friends' words than unknown comments. In this paper, we develop an appraisal mechanism for social marketplace to search the product requests from buyer's social network and verify product providers based on the experience of friends within a buyer's social network. The proposed framework provides a social search mechanism to explore the product providers and estimates trustworthiness values of product providers from the view of social network for helping buyers solve the inaccuracy and inconvenience issues in social marketplace.
