14. An article for merging two or more knowledge bases comprising a tangibly embodied machine-readable medium operable to cause one or more machines to result in operations comprising: applying association-grounded semantics to collapse a language of each of the knowledge bases to obtain a single class of predicates for each language; and mapping the classes of predicates for the knowledge bases into a common language to generate a merged knowledge base.
16. An article as in claim 14 , wherein at least two of the languages are disjoint and wherein the mapping further comprises: identifying an isomorphism between graphs of the knowledge bases that represent assertions of the knowledge bases.
