ResolveByScore

public ResolveByScore(IMWEDetector detector,
                      boolean chooseLargest)

Constructs a new MWE detector constraint that wraps the specified MWE Detector.

Parameters:

detector - the detector wrapped by this object, may not be NullPointerException

chooseLargest - true if the largest score should be chosen; false if the smallest should be used.

Throws:

java.lang.NullPointerException - if the specified detector is null

Since:

Method Detail

detect

public <T extends IToken> java.util.List<IMWE<T>> detect(java.util.List<T> sentence)

Description copied from interface: IMWEDetector

Given a list of tokens, the detector searches for the MWEs in the list. It returns a set of IMWE objects representing these multi-word expressions. The method returns an empty list if no MWEs are found; the method should never return null.

Specified by:

detect in interface IMWEDetector

Overrides:

detect in class HasMWEDetector

Type Parameters:

T - the type of the tokens in the sentence

Parameters:

sentence - a sentence which the detector should search for multi-word expressions.

Returns:

a list of IMWE objects representing the multi-word expressions found in the sentence. Returns an empty list if no multi-word expressions are found; never returns null

getScorer

protected abstract <T extends IToken> IScorer<IMWE<T>> getScorer(java.util.List<T> sentence)

Returns the scoring function for this filter.

Type Parameters:

T - they type of the token

Parameters:

sentence - the sentence to be scored

Returns:

the scorer
