An Application of HodgeRank to Online Peer Assessment

In this paper, we construct a reference score for online peer assessments based on HodgeRank [5]. Peer assessment is a process in which students grade their peers assignments [2, 6]. A peer assignment system is used to enhance students learning process, especially in higher education. Through such a system, students are given the opportunity to not only learn knowledge from textbooks and instructors, but also from the process of making judgements on assignments completed by their peers. This process helps them understand the weaknesses and strengths in the work of others, and then to review their own. However, there are some practical issues associated with a peer assignment system.
