Summary
Classical path length based semantic similarities computes
the similarity between a pair of concepts of an ontology as the minimum
inter-link distance between those concepts, omitting the rest of taxonomical
knowledge. In this report, it is introduced an ontology-based semantic
similarity, which considers the amount of shared and non shared
taxonomical knowledge involving a pair of concepts to asses the semantic
similarity. In this report it is presented the triangle inequality demonstration
of the proposed measure.
Keywords
