Conflict of Interest (COI) detection has become a significant issue in reviewer recommendation system because it can cause bias in the actor decision during reviewing process. Therefore, it is important to find relationships between actors in the network to avoid COI. Unfortunately, due to incomplete information in the network or for privacy reason, we can not detect all of those relationship.
In this thesis, we proposed Conflict of Interest (COI) Detector in Reviewer Recommendation System. Our approach can detect four types of COI: 1) COI in Coauthorship; 2) COI in Potential Friendship; 3) COI in Academic Ranking; and 4) COI in Institution. Potential Friendship Finder intends to find potential link between nodes in the network. It also can be used to suggest future collaboration to the expert.
The experiment results show that our proposed approach have a high recal rates and can detected more than 95% COI from a list of reviewers in recommendation system. The system also can adapt well to various network topologies.
