Another Player in Semantic Search

A startup called Powerset debuted a new system of semantic natural-language Web searching on September 17. It's currently in a closed alpha, so I haven't been able to poke at it, but it sounds both ambitious and wonderful. Plus, it's build by PARC—the same folks who invented computer mice and GUIs. Here is the page for PARC's natural language processing research project, which is the technology used by Powerset.
