Constructor Detail

IllinoisLemmatizer

public IllinoisLemmatizer()

default configuration, lazily initialized

IllinoisLemmatizer

public IllinoisLemmatizer(boolean isLazilyInitialized)

default parameters, but set whether lazily initialized or not

Parameters:

isLazilyInitialized - if 'true', defer loading resources until getView() is called.

IllinoisLemmatizer

public IllinoisLemmatizer(ResourceManager nonDefaultRm)

Override default config parameters with properties in rm. Is lazily initialized by default.

Parameters:

nonDefaultRm - non-default configuration params

Method Detail

readFromClasspath

public static List<String> readFromClasspath(String filename)

main

public static void main(String[] args)

initialize

public void initialize(ResourceManager rm)

loads resources used by lemmatizer. By default, is called by Annotator superclass with ResourceManager passed in at construction time.

Specified by:

initialize in class Annotator

Parameters:

rm - configuration parameters

getLemma

public String getLemma(TextAnnotation ta,
                       int tokIndex)

get a lemma for the token at index tokIndex in TextAnnotation ta.

Parameters:

ta - TextAnnotation to query for lemma; MUST have POS view.

tokIndex - token index for word to lemmatize

Returns:

a String representing a lemma with the POS found for the corresponding word

getSingleLemma

@Deprecated
public String getSingleLemma(TextAnnotation ta,
                                         int tokIndex)

Deprecated.

included for backward compatibility: wraps getLemma().

Parameters:

ta - TextAnnotation to query. MUST have POS view.

tokIndex - index of word to lemmatize.

Returns:

a String representing the lemma of the queried word.

getLemma

public String getLemma(String word,
                       String pos)

gets the lemma (root form) corresponding to the specified word having the specified part of speech.

Parameters:

word - Word to lemmatize

pos - Part-of-speech of word

Returns:

String representing lemma (root form) of word

createLemmaView

public View createLemmaView(TextAnnotation inputTa)
                     throws IOException

create a Lemma view in the TextAnnotation argument, and return a reference to that View.

Throws:

IOException

addView

public void addView(TextAnnotation textAnnotation)
             throws AnnotatorException

Description copied from class: Annotator

create and add the view named by getViewName() to the TextAnnotation argument.

Specified by:

addView in class Annotator

Parameters:

textAnnotation - the TextAnnotation to modify.

Throws:

AnnotatorException
