de.uni_mannheim.informatik.dws.winter.matching.rules.MaxScoreMatchingRule<RecordType,SchemaElementType>

All Implemented Interfaces:

Comparator<RecordType,SchemaElementType>, RecordMapper<Correspondence<RecordType,SchemaElementType>,Correspondence<RecordType,SchemaElementType>>, Serializable

public class MaxScoreMatchingRule<RecordType extends Matchable,SchemaElementType extends Matchable>
extends FilteringMatchingRule<RecordType,SchemaElementType>

A matching rule that combines several other matching rules. Each individual matching rule is executed and the result with the highest similarity score is used as result.
