Title: Semantic Social Network Analysis
Speaker: Dr. Qingpeng Zhang, City University of Hong Kong
Time: 3:00 pm, April 7, 2017
Venue: Room 302, Building #12, Wushan Campus
Conventional bi-dimensional matrix-based social network analysis approaches ignore the inherent multiaspect relationships of people and other attributes (like semantics). In this research, we proposed to use a tensor-based machine learning framework to integrate such multiplex relationships for a variety of problems including link prediction, disease diagnosis and risk assessment. The speaker will first introduce a model for retweet prediction problem through linking twitter data to semantic web and factorizing tensors across domains with semantics embedded. Then, the speaker will describe a series of applications his group has been working on.
