HAI-3
The goal is to investigate the structure, evolution, and practices of
communities in social media with Flick as a target. In particular,
using statistical models relying on textual and social metadata, the
project will model the dynamical aspect of social media groups
(including topic and memberships patterns), study and discover
micro-activity patterns within sub-groups, and investigate the use of
visual information extracted from photos and videos to refine user and
group descriptions.
While each of the sub-projects pursues its
own goals, the grounding of the approaches on similar principled
methodologies (e.g. bag-of-words and Bayesian topic models) will provide
opportunities for research synergies and the strengthening of Idiap's
activities on human behavior and interaction modeling.
