Abstract
In recent online social networks, each user can often assign a value to their immediate friends level of trustworthiness. Understanding a social trust value between any two nodes in an online social network is beneficial in a range of applications, like online marketing and
recommendation systems. However, assessing social trust between two members in an online social network is difficult and time-consuming. This is because existing work either created handcrafted rules based on specialized domain knowledge or required a large number of
computational resources, limiting its scalability. Graph-based techniques have recently been proved to be effective at learning from graph data. Even though social trust may be represented as graph data, its advantages have a lot of potential for trust evaluation. Therefore, we begin by reviewing the characteristics of online social networks and the properties of trust. After which the two types of graph-simplification and graph-analogy methodologies would be compared and contrasted as well as their respective problems and obstacles. We then conduct a quick examination of its pre- and post-processes to present an integrated view of trust evaluation. Finally, we discuss some unresolved issues that all trust models face.
