Popis: Trust of the nodes plays an important role in users’ purchase decisions and trusted nodes can influence other nodes in the social commerce. The evaluation and prediction of users’ trustworthiness is also of great importance for social commerce marketing and promotion. However, analysis of trust and detection of what factors influence trust between users need investigation. This paper proposes a trust model and divides trust into direct trust and indirect trust which presented in the form of familiarity trust, similarity trust, prestige trust and ability trust. The respective weights of four attributes are calculated through entropy weight method. Different centrality approaches such as Eigenvector Centrality, PageRank and Katz Centrality are used to find influential nodes. We found similarity and prestige is relatively more important than familiarity and ability trust in users’ connections. Besides, there is a strong linear relationship between user nodes’ trust and their centrality.
