Class Mapping

java.lang.Object

it.unimi.dico.islab.idbs2.map.Mapping

All Implemented Interfaces:

Comparable<Mapping>

public class Mapping
extends Object
implements Comparable<Mapping>

Representation of a matching result. A possible use of this multi-leveled mappings representation could be by representing three different mapping levels:

• KC level mapping: the result of a matching operation between two KnowledgeChunks
• Property level mapping: the result of a matching operation between two KnowledgeChunk's properties (e.g. similarity between religions of Italy and religions of France)
• Predicate level mapping: the result of a matching operation between two Predicates (e.g. two property values)
