Multi-Collaborative Filtering Trust Network For Online Recommendation

Nowadays, Recommendation Systems (RS) play an important role in the e-Commerce business and they have been proposed to exploit the potential of social networks by filtering information and offering useful recommendations to customers. As the personalization service is built to present the users with highly relevant set of items, the customer loyalty of the web companies can be improved. Collaborative Filtering (CF) is believed to be a suitable underlying technique for recommendation systems based on social networks, since it harvests information both from similar products and from peer users to infer a suggested item out of many for a user. Meanwhile, social networks provide the needed collaborative social environment. The system we proposed here is the Multi-Collaborative Filtering Trust Network Recommendation System, which combined multiple sources, by using MovieLens, Delicious and Facebook datasets, measured trust, temporal relation and similarity factors. After series of experiments, we found that the performance of recommendation system with considering above four aspects is much better than considering any other single/combined aspects.
