All Implemented Interfaces:

AnalysisComponent

public class Evaluator
extends JCasAnnotator_ImplBase

This AE evaluates the system part-of-speech tags against the gold part-of-speech tags. This is a very simple approach to evaluation of part-of-speech tags that will not likely suffice in real-world scenarios for a number of reasons (e.g. no confusion matrix, assumes gold-standard tokens and sentences in the system view, etc.)

Method Details

process

public void process(JCas jCas)
             throws AnalysisEngineProcessException

Description copied from class: JCasAnnotator_ImplBase

This method should be overriden by subclasses. Inputs a JCAS to the AnalysisComponent. The AnalysisComponent "owns" this JCAS until such time as Annotator_ImplBase.hasNext() is called and returns false (see AnalysisComponent for details).

Specified by:

process in class JCasAnnotator_ImplBase

Parameters:

jCas - a JCAS that this AnalysisComponent should process.

Throws:

AnalysisEngineProcessException - if a problem occurs during processing

collectionProcessComplete

public void collectionProcessComplete()
                               throws AnalysisEngineProcessException

Description copied from interface: AnalysisComponent

Notifies this AnalysisComponent that processing of an entire collection has been completed. In this method, this component should finish writing any output relating to the current collection.

Specified by:

collectionProcessComplete in interface AnalysisComponent

Overrides:

collectionProcessComplete in class AnalysisComponent_ImplBase

Throws:

AnalysisEngineProcessException - if this component encounters a problem in its end-of-collection processing
