Google release RDFa/ microformat for recipes
[google.com ]

This makes me wonder - how far have they gone down the "semantic understanding/AI" road?

What if all of their categories of websites were built on a statistically-based notional RDF of that category?

Any takers?

Seems to me like Google is exploring several roads at the same time - for example, both microformat tagging as well as the heavier lifting that various types of semantic analysis can provide. Microformats are limited by the adoption rate of the marketplace, so Google can't depend on just that if they're going to do the best job.

Thanks for your thoughts tedster.

I guess was being a bit glib - I don't expect actual RDF for categories but more like:
"OK so they say they are sellers of widgets let's see - do they have:
a business address
a company number
employees by name
high level pages on widgets
detailed pages on widgets
etc"

I fascinated by what "relevance" means in the face of a perfectly disambiguated search query.

Cheers
