Interesting! There's also another related group here in W3Cland - an 
incubator on Uncertainty Reasoning for the Web, see
http://www.w3.org/2005/Incubator/urw3/ ...though things are only just 
starting up. The only mailing list traffic so far is about scheduling 
the first telecon.
The charter has some notes on what they're doing:
http://www.w3.org/2005/Incubator/urw3/charter ...and Bayes gets a few 
mentions there.

My inclination with RDF and evidence/probability, ... is that without 
reinventing the RDF graph model, it is likely easier to attach 
probability and other annotations to collections of statements, rather 
than to individual triples. This can be done for example by making 
assertions about an RDF/XML document, ... and is somehow related to the 
ability in SPARQL to associate a graph with a URI. For example see 
http://www.w3.org/TR/rdf-sparql-query/#queryDataset

cheers,
