Patent ID: 8539001

Claim:
A method of determining a value of a bridge of a first ontology schema with a second ontology schema, the method comprising the steps of: a computer generating the bridge of the first ontology schema (S1) with the second ontology schema (S2), wherein generating the bridge comprises identifying significant concepts included in S2, creating a sub-schema S based on the identified significant concepts, and importing the sub-schema S into S 1 which completes a generation of the bridge of S1 with S2; the computer extracting the sub-schema S from the bridge of S1 with S2; the computer creating a schema S′ from sub-schema S, wherein the creating the schema S′ comprises removing common concepts from S, removing from S relationships to the common concepts, and for each common concept to which first and second concepts have immediate links in S, the computer creating a new immediate link in S′ between the first and second concepts, the common concepts being concepts that S1 and S2 have in common; the computer determining an intrinsic value of S′; the computer determining a strength of a bridge of S1 with S; and based on the intrinsic value of S′ and the strength of the bridge of S1 with S, the computer determining the value of the bridge of S1 with S2.
