Social-Based Recommender Systems

Social-Based Recommender Systems

Social subgraph

Research Statement

Online social networks, such as Facebook, provide a wealth of information that we can leverage for recommending a variety of artifacts, such as news articles, movies, books, etc.  While recommender systems have been extensively researched since the mid-1990s, the study of social-based recommender systems is a new area.  One key insight is that social-based recommendations should account for a number of dimensions within a user’s social network, including social relationship strength, expertise, and user similarity.  We seek  to develop novel ensemble recommender systems that leverage these dimensions.  Our research intersects with a number of domains in computer science, including data mining, machine learning, information retrieval, human-computer interaction, and distributed systems.
