Class EmotionalKeywordSpotter

java.lang.Object
  emolib.util.proc.TextDataProcessor
      emolib.eks.EmotionalKeywordSpotter

All Implemented Interfaces:

Configurable, DataProcessor

Direct Known Subclasses:

EmotionalKeywordSpotterANLW

public abstract class EmotionalKeywordSpotter
extends TextDataProcessor

The EmotionalKeywordSpotter abstract class defines the general structure to perform the Emotional Keyword Spotting (EKS) process, which detects the words with an affective content and assigns them the pertinent emotional dimensions.

This module should work along with an affective dictionary, containing the emotional dimensions for each of the words in the database. Once the EmotionalKeywordSpotter detects the presence of an affective word, it tags it accordingly. Normally these dictionaries index stems of words in order to be as much extensive as possible. In order to surpass the conflation effect introduced by the stemming process, a POS disambiguation is used.

Constructor Detail

EmotionalKeywordSpotter

public EmotionalKeywordSpotter()

Main constructor of the Stemmer.

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 TextDataProcessor

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 TextDataProcessor

Parameters:

ps - a property sheet holding the new data

Throws:

PropertyException - if there is a problem with the properties.

getData

public Data getData()
             throws DataProcessingException

Obtains the TextData from the previous module, processes it and makes it available to the rest of the text processing chain.

Specified by:

getData in interface DataProcessor

Specified by:

getData in class TextDataProcessor

Returns:

The next available Data object, returns null if no Data object is available.

Throws:

DataProcessingException - If there is a processing error.

initialize

public void initialize()

Method to initialize the Stemmer.

Specified by:

initialize in interface DataProcessor

Overrides:

initialize in class TextDataProcessor

applyEKS

public abstract void applyEKS(TextData inputTextDataObject)

Method to perform the stemming process.

Parameters:

inputTextDataObject - The TextData object to process.
