5. The method of claim 1 , wherein the first corpus and the second corpus are unstructured text documents.
1. A computer-implemented method for bridging terminology differences between at least two subject areas, comprising executing the following steps on a computer: computing a first affinity measure between a first term in a first corpus, corresponding to a first subject area, and a bridge term; computing a second affinity measure between a second term in a second corpus, corresponding to a second subject area, and the bridge term; computing a third affinity measure between the first term and the second term based on the first affinity measure and the second affinity measure; wherein the bridge term is a term that appears in both the first corpus and the second corpus, wherein computing at least one of the first affinity measure and the second affinity measure comprises computing a transitive closure of an affinity matrix of at least one of the first corpus and the second corpus; assigning a score for a pair of terms in the transitive closure of the affinity matrix using a composite path probability, wherein the composite path probability is a computation of a sum of path probabilities for n paths between the pair of terms, wherein n is an integer greater than 0.
