Implicit Media Knowledge

These years, the number of visual media (e.g. images, photos, videos…) is exponentially increasing with the apparition of new technologies. Most of these media are shared on the Web with the apparition of social networks such as FaceBook, MySpace, Flickr… The problem related to the media extraction and indexing is become a big issue as the need is become primordial to efficiently retrieve the right media among millions of media. Firstly, we will present an overview of some existing visual media indexing/retrieval systems and its related limitations/improvements. Secondly, we will present a new way to improve media indexing/retrieval without effort: it is based on the analysis of media usage (via implicit user actions on media) in order to enrich media with pertinent information.
