For quite a few years now, Tim Berners-Lee, the creator of the world-wide web, and others have tried to create a Semantic Web where web documents include actual machine-usable knowledge in the form of facts, relations, and rules. Recently there has been an uptick in interest and activity, so much so that Franz Inc., the home of AllegroLisp, now have a separate set of commercial products for doing Semantic Web processing. Interestingly, much of the interest is coming from social networking application developers, using the network graph processing aspects of these technologies more than the semantic information aspect.
