We've got a decent amount of discussion about Phrase-Based Indexing [webmasterworld.com] in this forum, too. And I agree with crobb305. Panda is designed to measure "quality" so it seems clear that some kind of semantic processing is involved, even if there's been little discussion about that possibility so far.
