One way to approach this problem is to use a framework to mix logical
constraints with probabilistic ones.  My colleague Yun Peng has been
exploring integrating data backed by OWL ontologies with Bayesian information,
with applications for ontology mapping.  See [1] for recent papers on this
as well as a recent PhD thesis [2] that I think also may be relevant.
