Class SameAdditionalInfoStructureElementSimilarity

java.lang.Object

it.uniroma2.sag.kelp.data.representation.structure.similarity.SameAdditionalInfoStructureElementSimilarity

All Implemented Interfaces:

StructureElementSimilarityI

public class SameAdditionalInfoStructureElementSimilarity
extends Object
implements StructureElementSimilarityI

Implements a similarity between StructureElements that first verifies whether two structure elements contains the same additional informations in a list of specified additional informations. If at least one additional information is contained in one of the structure element, but not in the other their similarity is set to 0. Otherwise their similarity is estimated applying another structure element similarity specified by the class field baseSimilarity
