Class DefaultMorphologicalProcessor

java.lang.Object

net.sf.extjwnl.dictionary.morph.DefaultMorphologicalProcessor

All Implemented Interfaces:

MorphologicalProcessor

public class DefaultMorphologicalProcessor
extends java.lang.Object
implements MorphologicalProcessor

Default implementation of MorphologicalProcessor. This isn't a true morphological analyzer (it doesn't figure out all the characteristics of each word it processes). This is basically a stemmer that uses WordNet exception files instead of complex stemming rules. It also tries to be intelligent by removing delimiters and doing concatenation.

DefaultMorphologicalProcessor

public DefaultMorphologicalProcessor(Dictionary dictionary,
                                     java.util.Map<java.lang.String,Param> params)
                              throws JWNLException

Throws:

JWNLException

Method Detail

lookupBaseForm

public IndexWord lookupBaseForm(POS pos,
                                java.lang.String derivation)
                         throws JWNLException

Lookup the first base form of a word. Given a lemma, finds the WordNet entry most like that lemma. This function returns the first base form found. Subsequent calls to this function with the same part-of-speech and word will return the same base form.

Specified by:

lookupBaseForm in interface MorphologicalProcessor

Parameters:

pos - the part-of-speech of the word to look up

derivation - the word to look up

Returns:

IndexWord the IndexWord found during lookup or null

Throws:

JWNLException - JWNLException

lookupAllBaseForms

public java.util.List<java.lang.String> lookupAllBaseForms(POS pos,
                                                           java.lang.String derivation)
                                                    throws JWNLException

Returns all base forms of the derivation.

Specified by:

lookupAllBaseForms in interface MorphologicalProcessor

Parameters:

pos - part of speech

derivation - derivation

Returns:

base forms of the derivation

Throws:

JWNLException - JWNLException

getDictionary

public Dictionary getDictionary()
