public interface SMOntologyAggWeighted
extends SMOntology

Calculates the similarity between query and case based on the local similarities of the connected objects of the query and case entities via specific relations in an ontology. The local similarity calculations can be defined by the name of the relation, a similarity measure to be used and a weight for the weighted average.
