kb.matching.AbstractMatcher

kb.matching.AbstractTupleMatcher

Direct Known Subclasses:

BasicTupleMatcher

public abstract class AbstractTupleMatcher
extends AbstractMatcher

Abstraction of the operations for matching two tuples, where one is considered the "master". A tuple matcher has a concept matcher, which is by default the BasicConceptMatcher, but can be set to any concept matcher desired.

AbstractTupleMatcher

public AbstractTupleMatcher(AbstractConceptMatcher matcher)

Creates a new instance of a tuple matcher where the concepts will be matched using the given concept matcher.

Parameters:

matcher - any concept matcher. If null, then use the BasicConceptMatcher.

AbstractTupleMatcher

public AbstractTupleMatcher()

Method Detail

compare

public abstract float compare(BinaryTuple masterTuple,
                              BinaryTuple tupleToMatch)

Perform a possible comparison between two tuples. Does not alter either of the tuples given as arguments.

Parameters:

masterTuple - the relation tuple considered to be the "correct" one (if any)

tupleToMatch - the candidate tuple that we want to match to the master.

Returns:

possible match score; zero otherwise.

scoreTupleMatch

public abstract float scoreTupleMatch(MatchedBinaryTuple masterTuple,
                                      MatchedBinaryTuple tupleToMatch)

Performs the comparison between master and matchable tuple. May alter either of the tuples given as arguments.

Returns:

match score; zero otherwise.
