Constructor Detail

BaseSynthesizer

public BaseSynthesizer(String resourceFileName,
               String tagFileName)

Parameters:

resourceFileName - The dictionary file name.

tagFileName - The name of a file containing all possible tags.

Method Detail

getDictionary

protected morfologik.stemming.Dictionary getDictionary()
                                                throws IOException

Returns the Dictionary used for this synthesizer. The dictionary file can be defined in the constructor.

Throws:

IOException - In case the dictionary cannot be loaded.

createStemmer

protected morfologik.stemming.IStemmer createStemmer()

Creates a new IStemmer based on the configured dictionary. The result must not be shared among threads.

Since:

2.3

lookup

protected void lookup(String lemma,
          String posTag,
          List<String> results)

Lookup the inflected forms of a lemma defined by a part-of-speech tag.

Parameters:

lemma - the lemma to be inflected.

posTag - the desired part-of-speech tag.

results - the list to collect the inflected forms.

synthesize

public String[] synthesize(AnalyzedToken token,
                  String posTag)
                    throws IOException

Get a form of a given AnalyzedToken, where the form is defined by a part-of-speech tag.

Specified by:

synthesize in interface Synthesizer

Parameters:

token - AnalyzedToken to be inflected.

posTag - The desired part-of-speech tag.

Returns:

inflected words, or an empty array if no forms were found

Throws:

IOException

synthesize

public String[] synthesize(AnalyzedToken token,
                  String posTag,
                  boolean posTagRegExp)
                    throws IOException

Description copied from interface: Synthesizer

Generates a form of the word with a given POS tag for a given lemma. POS tag can be specified using regular expressions.

Specified by:

synthesize in interface Synthesizer

Parameters:

token - the token to be used for synthesis

posTag - POS tag of the form to be generated

posTagRegExp - Specifies whether the posTag string is a regular expression.

Throws:

IOException

getPosTagCorrection

public String getPosTagCorrection(String posTag)

Description copied from interface: Synthesizer

Gets a corrected version of the POS tag used for synthesis. Useful when the tagset defines special disjunction that need to be converted into regexp disjunctions.

Specified by:

getPosTagCorrection in interface Synthesizer

Parameters:

posTag - original POS tag to correct

Returns:

converted POS tag

getStemmer

public morfologik.stemming.IStemmer getStemmer()

Returns:

the stemmer interface to be used.

Since:

2.5

initPossibleTags

protected void initPossibleTags()
                         throws IOException

Throws:

IOException
