An approach is presented for determining a value of an association between first and second ontologies, S1 and S2. A first bridge of S1 with S2 is generated. A schema S' is created from sub-schema S extracted from the first bridge by removing common concepts and relationships to the common concepts, and for each common concept to which first and second concepts have immediate links in S, by creating a new immediate link in S' between the first and second concepts. Based on an intrinsic value of S' and a strength of the bridge of S1 with S, a value of the first bridge is determined. Similarly, a value of a second bridge of S2 with S1 is determined. A value of the association between S1 and S2 is determined based on a sum of the values of the first and second bridges. |
