Social Computing

The work in the Social Computing Group integrates theories and models from ubiquitous computing, social media, machine learning, and social sciences, to sense, analyze, and interpret human and social behavior in everyday life, and to create devices and systems that support interaction and communication. Current research includes methods for urban computing from phone and mobile social network data, behavioral analysis of social video, ubiquitous sensing of face-to-face interaction, and crowdsourcing.

Idiap project CODICES broadcasted on euronews.net "Archaeology Mayan script"
research — Jun 24, 2010

Dr Daniel Gatica-Perez, (from the Idiap Research Institute, in Martigny, Switzerland): “People who are exploring ancient Maya culture – in order to try to find glyphs, they usually use catalogues and this is a classic catalogue. It’s like a telephone book. Instead of names what we have are essentially glyphs and this is a very large collection. And, essentially, if you don’t have computational means to find a glyph you don’t know or a glyph you are learning about, you probably have to parse all of these manually. And this can be time consuming.”
