SIAM: Social Interaction Analysis for Multimedia

Abstract. This paper describes the SIAM demonstrator, a system that illustrates the usefulness of indexing multimedia segments thanks to associated microblog posts. From on a socialized multimedia content (i.e. video and associated microblog posts on Twitter), the system applies text mining techniques and de-rives a topic model to index socialized multimedia segments. This result may then be used inside many multimedia applications, such as in-media social navigation, multimedia summarization or composition, or exploration of multimedia collections according to various socially-based viewpoints.
