Mediating and Analyzing Social Data

Web 2.0 is turning current Web into social platform for knowing people and sharing information. The Web is strongly socially linked than ever. This paper takes major social tagging systems as examples, namely delicious, flickr and youtube, to analyze the social phenomena in the Social Web in order to identify the way of mediating and linking social data. A simple Upper Tag Ontology (UTO) is proposed to integrate different social tagging data and mediate and link with other related social metadata.
