LeskWordSenseDisambiguation

public LeskWordSenseDisambiguation()

Method Detail

setup

public void setup(OntologyReader reader)

Initializes the WordSenseDisambiguation algorithm with the given OntologyReader. Any other configuration values should be set via the global system properties object.

processContext

protected void processContext(edu.stanford.nlp.pipeline.Annotation focus,
                              edu.stanford.nlp.pipeline.Annotation result,
                              Queue<edu.stanford.nlp.pipeline.Annotation> prevWords,
                              Queue<edu.stanford.nlp.pipeline.Annotation> nextWords)

Processes the local context surrounded focus. This should update focus with any word sense disambiguation Annotations discovered.

Specified by:

processContext in class SlidingWindowDisambiguation

Parameters:

focus - The Annotation to disambiguate.

prevWords - The N Annotation words before focus.

nextWords - The N Annotation words after focus.

toString

public String toString()

Returns "ld", the acronyms for this WordSenseDisambiguation algorithm.

Overrides:

toString in class Object
