The Semantic Web
is the new-generation Web that tries to represent information so that it can be used by machines not just for display purposes,
but for automation, integration, and reuse across applications (Boley et al. 2001). It has been one of the hottest R&D topics
in recent years in the AI community, as well as in the Internet community—the Semantic Web is an important W3C
activity (SW Activity 2008).
