OntologySimilarity ================== @LICENSE see LICENSE file @authors OntologySimilarity : Alok Dhamanaskar, Michael Cotterell, Rui Wang @authors OntologyManager : Yung Long Lee @authors stringMatcher : Akshay Choche The implementation of the algorithm is based on Concept Similarity explained in Rui Wang's paper ( Ranking-Based Suggestion Algorithms for Semantic Web Service Composition ) * The Package OntologySimilarity provides functionality to calculate a similarity score between two concepts in the same Ontology. It considers both syntactic and logical definition of an OWL Class. * It takes into account: + Relative Position of two concepts in the Ontology (Coverage Score) + Syntactic Definition (Definition + Label) (Syntactic Score) + Properties and restrictions on them for the OWL class in consideration * The main Package OntologySimilarity has two Internal dependencies: OntologyManger (For Loading and processing the Ontology), And StringMetrics. * Ontology Manager uses OWLAPI (http://owlapi.sourceforge.net/) to load the Ontology, its imports, and retrieve various aspects of an OWL class required for computation of the Similarity * For testing use : ontologySimilarityOntologySimilarityImpl.java Class For Printing out the intermediate steps and subscore set static final Level debug = Level.INFO; * The package has been Tested on ontologies OBI and OBI-WS (http://code.google.com/p/obi-webservice/) and should work well with most ontolofies under BFO. * For Other Ontologies, Change relevant annotation properties in ontologyManager.ontologySimilarity.properties Properties file
