Agree completely -- which is why I sent a base file which had the  
conditional probabilities, the mapping, and the values to be able to  
compute marginals.
About the URIs, I should have added in my email that because freebase  
types are not URIs, and have types such as /people/person, we added a  
base URI: http://freebase.com to the types.  Sorry I missed  
mentioning that...
