So many words that we use in a computer science context come from human interactions: trust, recommendations, reputation. So that is why I was very interested when I read about this workshop:
Web Science is an emerging interdisciplinary field that lies at the boundary of Computer Science, Sociology, Psychology, Media, Economics and Law. Its aim is to understand the Web and its impact on the way people think, behave and interact. This workshop is for people who believe that their work could be part of this new discipline and who are interested in helping to define Web Science. We invite position papers on a variety of technical topics with a human slant, including Social Collaboration, Knowledge Interfaces, Collective Intelligence and Emergent Structures.
The call, however, is closed; see (and read) the list of accepted papers on the link above.
