Glossary

Collaborative filtering

A type of recommendation technique.

Matrix factorization

Factorizing the user-item matrix into user latent matrix and item latent matrix.

Recommender system

A system that provides recommendations for users.

Social relations

Various social relationships between users, like social trust relationships.

Definition

The research of social recommendation aims at modeling recommender systems more accurately and realistically. The characteristic of social recommendation that is different from the tradition recommender system is the availability of social network, i.e., relational information among the users. Social recommendation focuses on how to utilize user social information to effectively and efficiently compute recommendation results.
