All Implemented Interfaces:

Configurable, DataProcessor

public class SimLibWSD
extends WordSenseDisambiguator

The SimLibWSD class performs the Word Sense Disambiguation (WSD) process using the WordNet Similarity library.

In order to perform this process, the word-sense disambiguator is based on the system proposed by (Seco et al., 2004).

The SimLibWSD class requires a configuration parameter that indicates the location of the necessary files that represent the indexed WordNet structure. SimLibWSD depends on the (adapted) code developed by Nuno Seco for the WordNet Similarity library.

Method Detail

register

public void register(java.lang.String name,
                     Registry registry)
              throws PropertyException

Description copied from interface: Configurable

Register my properties. This method is called once early in the time of the component, shortly after the component is constructed. This component should register any configuration properties that it needs to register. If this configurable extends another configurable, super.register should also be called

Specified by:

register in interface Configurable

Overrides:

register in class WordSenseDisambiguator

Parameters:

name - the name of the component

registry - the registry for this component

Throws:

PropertyException

newProperties

public void newProperties(PropertySheet ps)
                   throws PropertyException

Description copied from interface: Configurable

This method is called when this configurable component has new data. The component should first validate the data. If it is bad the component should return false. If the data is good, the component should record the the data internally and return true.

Specified by:

newProperties in interface Configurable

Overrides:

newProperties in class WordSenseDisambiguator

Parameters:

ps - a property sheet holding the new data

Throws:

PropertyException - if there is a problem with the properties.

initialize

public void initialize()

Method to initialize the SimLibWSD.

Specified by:

initialize in interface DataProcessor

Overrides:

initialize in class WordSenseDisambiguator

applyWSD

public void applyWSD(TextData inputTextDataObject)

Method to perform the word-sense disambiguation process. The meaning is taken at paragraph-level (all text obtained from a single acquisition) for all the nouns in the text.

Specified by:

applyWSD in class WordSenseDisambiguator

Parameters:

inputTextDataObject - The TextData object to process.
