Folksonomy Tagging as Subject Identity Assertions

Hi Folks,

Been doing some searching, but haven't found much detail about practical applications of using existing folksonomy classifications (e.g. tagging) to derive or infer subject identity in varying degrees of relevance.  Most of what I saw on "semantic tagging" or anything similar I could think of a search kewords has the opposite: provide a way to more precisely tag resources using the proper semantics, vs. the bottom-up approach that I'm looking for.

Has anyone seen anything about this related to Topic Maps or have people trying to map large bodies of existing information done anything in this space already?

I have a few thoughts about how something like this could work to generate degrees of certainty in subject identity, but they're just thoughts

Anyone doing this sort of thing with Topic Maps?

Cheers,

ast
