LSI/LSA – Is MSN Ahead of GOOGLE in AI?

In another thread it was claimed that MSN has the advantage over GOOGLE in their algorithms in the use of Artificial Intelligence (AI) utilizing LSI/LSA.

I have yet to see anything substantial indicating that MSN has endeavored to that extent. Yet, GOOGLE selects what they determine to be the most accurate description of a page from multiple on page and off page components for SERP listings including a recent revisited importance favoring the “Description Metatag” when determined relevant. IMO – That indicates to me that LSI/LSA has been established to some extent.

What are your thoughts?
