There has been plenty of hype around the Semanic Web, but will we ever see the vision of intelligent agents working on our behalf? This talk will introduce the concepts of the Semantic Web as envisioned by Tim Berners-Lee over 10 years ago and compare that vision to where we have come since then. It will include a discussion of implementations such as XML, RDF, OWL (web ontology language), and SPARQL. After reviewing the design principles and enabling technologies, William shows how these techniques can be implemented in WebGUI. The goal of this talk will be to show how to make your web sites more relevant to users.
