The document discusses the potential for a "Social Semantic Web" where Semantic Web technologies could support online communities generated by social networks, and those communities could also contribute semantic data by connecting information. It notes that while the Social Web and Semantic Web have seen success individually, fully realizing their integration as a Social Semantic Web has yet to be achieved. Challenges include getting users to adopt shared ontologies and developing systems that are ubiquitous, real-time, and proactive.
