Finding the Most Similar Concepts in Two Different Ontologies

A concise manner to send information from agent A to B is to use phrases constructed with the concepts of A: to use the concepts as the atomic tokens to be transmitted. Unfortunately, tokens from A are not understood by (they do not map into) the ontology of B, since in general each ontology has its own address space. Instead, A and B need to use a common communication language, such as English: the transmission tokens are English words.An algorithm is presented that finds the concept C_B in O_B (the ontology of B) most closely resembling a given concept C_A. That is, given a concept from ontology O_A, a method is provided to find the most similar concept in O_B, as well as the similarity sim between both concepts. Examples are given.
