Semantic web believers including Tim Berners-Lee and Nova Spivack like to say that the social graph is part of their semantic world: the Giant Global Graph (GGG) as coined by Tim Berners-Lee. But the Giant Global Graph itself is like Dustin Hoffman’s autistic savant character Raymond Babbitt in the 1988 movie Rain Man. Raymond knew all about plane trips but couldn’t make sense of human relationships.
Web inventor Tim Berners-Lee uses the Social Graph meme to rebrand his semantic web efforts, writing in a blog post, “I called this graph the Semantic Web, but maybe it should have been Giant Global Graph!” Berners-Lee thinks there could be big payoff in adding a layer of meaning atop the documents of the World Wide Web:
So, if only we could express these relationships, such as my social graph, in a way that is above the level of documents, then we would get re-use. That’s just what the graph does for us. We have the technology — it is Semantic Web technology, starting with RDF OWL and SPARQL. Not magic bullets, but the tools which allow us to break free of the document layer. If a social network site uses a common format for expressing that I know Dan Brickley, then any other site or program (when access is allowed) can use that information to give me a better service. Un-manacled to specific documents.
