Seminar Announcement

Title: "Web-based Social Network Analysis for Socially Intelligent Applications"

Jennifer Golbeck, University of Maryland

Room and time: SEO 1000, Tuesday, November 22, 2pm

The immense popularity of social networks on the web make them an attractive data source. When these networks are represented in Semantic Web formats, distributed social network information can be integrated into a single large model that can be analyzed. In this talk, I will present research on computational methods for understanding relationships in web-based social networks- particularly trust relationships. I will then describe projects where the results of these analyses are used to create socially intelligent applications. The most prominent of these is the FilmTrust system, a web-based social network that uses trust in social networks to create predictive movie recommendations. In this context, I show that the social computations outperform more traditional collaborative filtering techniques in certain cases. These results are used as a motivation for future work that can take advantage of the massive, publicly available resource offered by social nets.
