I’m attending the “Web2.0 and Social Software” session. On the presenter’s slides, I always read “Making Semantic Web Real”. I wonder if a lot of the things now claimed to be “Semantic Web” projects really belong to the field. I have the impression that it’s often just a desperate effort to keep the label after the rather slow uptake in the last years. E.g., just using RDF somewhere in an application doesn’t make it a Semantic Web application…
Tim O’Reilly gives a very nice explanation about Semantic Web and Web2.0 in this posting:
And so, it seems to me that Pagerank illustrates the fundamental difference between the approaches of the Semantic Web and Web 2.0. The Semantic Web sees meaning as something that needs to be added to documents so that computers can act intelligently about them. Web 2.0 seeks to discover the ways that meaning has already been implicitly encoded by the way people use documents and digital objects, and then to extract that meaning, often by statistical means by studying large aggregates of related documents.
Don’t get me wrong: Using Semantic Web Technologies is fine when trying to add some more semantics, e.g., to provide recommendations. But we may not rely just on these technologies, we have to develop hybrid approaches in the future. Welcome to Web3.0!
