Semantic technologies offer a standard form for representing information and knowledge that enables computers to collect, analyse, retrieve and share information more effectively and precisely and in new ways.
Social information systems such as Facebook, YouTube and Wikipedia are characterised by user-generated content intended for consumption and sharing by humans.
The research group for Semantic and Social Information Systems studies the intersection of these two ongoing and central developments in the ICT field.
While semantic and social information systems may appear unrelated at first, we consider them complementary. Social media tends to produce large collections of user-generated content that can potentially be leveraged by semantic technologies if they can be enriched (or “lifted”) semantically. For example, social technologies can be used to add dynamic, contextual semantics to Information Systems, whereas semantic technologies can be used to make the contents of social information systems more findable and better organised.
