Class DefaultMorphologicalProcessor

java.lang.Object

net.didion.jwnl.dictionary.morph.DefaultMorphologicalProcessor

All Implemented Interfaces:

MorphologicalProcessor, Createable

public class DefaultMorphologicalProcessor
extends Object
implements MorphologicalProcessor

Default implementation of MorphologicalProcessor. This isn't a true morpological 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 concatanation.

Method Details

create

public Object create(Map params)
              throws JWNLException

Specified by:

create in interface Createable

Throws:

JWNLException

lookupBaseForm

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

Lookup the 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. To find another base form for the pos/word, call lookupNextBaseForm.

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

Throws:

JWNLException

lookupAllBaseForms

public List lookupAllBaseForms(POS pos,
 String derivation)
                        throws JWNLException

Description copied from interface: MorphologicalProcessor

Return all the base forms of derivation

Specified by:

lookupAllBaseForms in interface MorphologicalProcessor

Throws:

JWNLException
