Abstract: The lack of collaboration among learners has proven to be an influential factor for their demotivation and disengagement. In MOOCs which are overpopulated by a huge number of learners, with heterogeneous communications and ever-changing behaviours, trust concerns can easily discourage learners to interact among their co-learners. Hence, supporting learners to find trusted peers to collaborate with is a promising solution to overcome this problem. In this paper, we offer a study of certain representative trust models pertaining to online social networks (OSNs) and social internet of things (SIoT). This analysis allows us to reach the following objectives: 1) clearer comprehension of these algorithms and understanding how to assess trust between entities; 2) determine the central elements requested for an efficient trust model; 3) be in a position to elaborate an adapted MOOC trust model.

Keywords: trust models; online social networks; OSNs; social internet of things; SIoT; MOOC platform; social tutoring.
