Tim O'Reilly at O'Reilly radar - Web2Summit: Radar Networks Unveils twine.com:

"Nova Spivack of Radar Networks plans to unveil the first application built on their semantic web platform, twine, a new kind of personal and group information manager. I've only seen a demo, and haven't had a chance to play with it hands-on or load in my own documents, but if it delivers what Nova promises, it could be revolutionary.

Underlying twine is Radar's semantic engine, trained to do what is called entity extraction from documents. Put in plain language, the semantic engine auto-tags each document, turning each entity into what looks like a web link as well as a tag in the sidebar. Type a note in twine, and it picks out all of the people, places, companies, books, and other types of information contained in the note, separating them out by type."
