On2broker: Semantic-Based Access to Information Sources at the WWW
Buchtitel: Proceedings of the World Conference on the WWW and Internet (WebNet 99), Honolulu, Hawai, USA, October 25-30, 1999
On2broker provides brokering services to improve access to heterogeneous, distributed and semistructured information sources as they are presented in the World Wide Web. It relies on the use of ontologies to make explicit the semantics of web pages. In the paper we will discuss the general architecture and main components of On2broker and provide some application scenarios. We show how we can provide semantic based access to web sources described with HTML, XML, or RDF.
