= Definition: SimilarityMeasure =

The concept of a SimilarityMeasure in the PhaseLibs describes an interface to measure a distance (of any kind) between two ontology entities ([wiki:Frame Frames]). These entities can be taken from the same, or from two different ontologies. The resulting value is rquired to be in the interval [0..1].

A SimiliarityMeasure can use any information available (i.e. accessible via the ontology model interface) about the given entities ([wiki:Frame Frames]).

Furthermore a SimiliarityMeasure can calculate a matrix of similarities to enable the algorithm to work more efficiently on large batches.

This concept is represented by the class [http://phaselibs.opendfki.de/repos/trunk/PhaseLibs/doc/JavaDoc/de/dfki/km/phaselib/model/evidence/SimilarityMeasure.html SimilarityMeasure].
