Watson: a gateway for next generation semantic web applications

The amount of knowledge published on the Semantic Web – i.e, the number of ontologies and semantic documents available online – is rapidly increasing. Following this evolution, changes appear in the way semantic applications are designed: instead of relying on one, self engineered base of semantic data, these next generation Semantic Web applications [2] assume the existence and availability of a large scale, distributed Web of data. In order for these applications to be able to exploit and combine the increasing amount of semantic data and ontologies available online, a gateway to the Semantic Web is required.
