Using the Semantic Web for linking and reusing data across Web 2.0 communities

Large volumes of content (bookmarks, reviews, videos, etc.) are currently being created on the “Social Web”, i.e. on Web 2.0 community sites, nd this content is being annotated and commented upon. The ability to view an individual’s entire contribution to the Social Web would be an nteresting and valuable service, particularly important as social networks are often being formed through created content and things that people ave in common (“object-centred sociality”). SIOC is a Semantic Web research project that aims to describe online communities on the Social eb. This paper describes how SIOC and the Semantic Web can enable linking and reuse scenarios of data from Web 2.0 community sites, and ntroduces a SIOC Types module to further specify the type of content items and act as a “glue” between user posts and the content items created nd annotated by users.
