ZDnet covers the semantic web:

Danny Hillis (Metaweb), Barney Pell (Powerset) and Nova Spivack (Radar Networks) shared the stage for a session on the semantic Web at the Web 2.0 Summit.

All three are developing services that bake more intelligence into the Web. And, the companies are all well funded, hyped and loaded with experience and talent.

The semantic web, implicit web, social graphs. These all deal with making the internet smarter. They hold a bevy of information, the key is figuring out how to take that information and make people’s lives easier. Out of the three companies, I personally find what Twine is doing to be the most interesting.

This is a very interesting statement,

Twine is about knowledge networking, rather than social networking, Spivack said. “The semantic graph is a superset of the social graph.” Rather than just relationships, Twine makes connections between everything based on underlying semantic Web technologies.
