Trust-Based Recommendations for Publications - A Multi-Layer Network Approach

Current recommender systems using network data focus on a single network, either a trust or a document reference network. However, in a number of applications, several types of networks need to be taken into account. The paper describes an architecture for a recommender system for publications that integrates information from different networks. Relationships in the trust network are modeled in a semantically rich way to reflect trust relationships from the real life in a concise way.
