SPARQL: Web 2.0 Meet the Semantic Web
The Semantic Web. It's an odd duck, and not only from the publishing point of view. Academic computer science is starting to take the Semantic Web (which means, for them, webizing the Knowledge Representation part of AI) seriously. There are conferences, journals, books. Government-funded SW research, especially in the EU (but also in the US and Japan), is also on the rise.
But in the geeky technical world, everything is about Web 2.0, not the Semantic Web. Which is fine, since there is considerable overlap between the Web, Web 2.0, and the Semantic Web. Lots of overlap, actually, and some pretty similar goals; the differences are mostly about use cases, emphasis, and some technical approach.
