Constructor Detail

CompositeDetector

public CompositeDetector(IMWEDetector... ds)

Constructs a composite detector from an array of detectors. The array of detectors should be ordered by descending preference. The most preferred detector should be first, the second-most-preferred second, etc. If there is a conflict between multi-word expressions found by two detectors, the multi-word expression found by the more-preferred detector will be chosen.

Parameters:

ds - the array of detectors in order of descending preference. May not be null. May not contain any null detectors.

Throws:

java.lang.NullPointerException - if the specified array is null or if any of the detectors in the list are null.

Since:

jMWE 1.0.0

CompositeDetector

public CompositeDetector(java.util.List<? extends IMWEDetector> ds)

Constructs a composite detector from a list of detectors. The list of detectors should be ordered by descending preference. The most preferred detector should be first, the second-most-preferred second, etc. If there is a conflict between multi-word expressions found by two detectors, the multi-word expression found by the more-preferred detector will be chosen.

Parameters:

ds - the list of detectors in order of descending preference. May not be null. May not contain any null detectors.

Throws:

java.lang.NullPointerException - if the specified list is null or if any of the detectors in the list are null.

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

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
