Class InflectionPattern

java.lang.Object
  extended by edu.mit.jmwe.detect.HasMWEDetector
      extended by edu.mit.jmwe.detect.InflectionPattern
All Implemented Interfaces:
IHasMWEDetector, IMWEDetector, IMWEDetectorFilter

public class InflectionPattern
extends HasMWEDetector
implements IMWEDetectorFilter

Uses a given IMWEDetector to find multi-word expressions in a sentence but discards inflected multi-word expressions if the inflected form does not correspond to an inflection pattern give by a set of inflection rules.

This implementation uses the default set of inflection rules listed in InflectionRule. Subclasses may change the set of rules by overriding the getRules() method.

Constructor Detail

InflectionPattern

public InflectionPattern(IMWEDetector d)
Constructs the detector from the given backing detector.

Parameters:
d - the IMWEDetector that will be used to back this detector. May not be null.
Throws:
NullPointerException - if the backing detector is null
Since:
jMWE 1.0.0
Method Detail

detect

public <T extends IToken> List<IMWE<T>> detect(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

getRules

public Collection<IInflectionRule> getRules()
Returns the set of inflection rules to be used by this detector. May be empty but may not be null.

Returns:
the set of inflection rules to be used by this detector.
Since:
jMWE 1.0.0
