I will fix the URIs.. I believe the equivalenceClass assertions were added in by someone at OpenLink (I just sent the raw file with the conditional probabilities for each pair of types that were above the . 80 threshold). So can whoever uploaded the file fix the property to what Tim suggested? Thanks!
