Watson is a gateway to the Semantic Web: it collects, analyzes and gives access to ontologies and semantic data available online. Its objective is to support the development of next generation Semantic Web applications that dynamically select, combine and exploit the knowledge published on the Semantic Web. We present the design of Watson, which have been(More)
Although research on integrating semantics with the Web started almost as soon as the Web was in place, a concrete Semantic Web that is, a large-scale collection of distributed semantic metadata emerged only over the past four to five years. The Semantic Web's embryonic nature is reflected in its existing applications. Most of these applications tend to(More)

While folksonomies allow tagging of similar resources with a variety of tags, their content retrieval mechanisms are severely hampered by being agnostic to the relations that exist between these tags. To overcome this limitation, several methods have been proposed to find groups of implicitly interrelated tags. We believe that content retrieval can be(More)
Watson is a gateway to the Semantic Web: it collects, analyzes and gives access to ontologies and semantic data available online with the objective of supporting their dynamic exploitation by semantic applications. We report on the analysis of 25 500 ontologies and semantic documents collected by Watson, giving an account about the way semantic technologies(More)
