All Implemented Interfaces:

CExampleExtractor, DocExampleExtractor<CExample>, java.io.Serializable, LBJ2.parse.Parser

public class CExExClosestPosAllNeg
extends CExampleExtractorBasic
implements java.io.Serializable

Generates examples of coreference in the following way: For each mention, create a positive example with the nearest preceding coreferential mention, and create negative examples with each preceding non-coreferential mention. To generate examples, first set the document using setDoc() and then call generateAllExamples().

Method Detail

generateAllExamples

protected java.util.List<CExample> generateAllExamples()

Generates a list of all the examples in the following way: For each mention, create a positive example with the nearest preceding coreferential mention, and create negative examples with each preceding non-coreferential mention. setDoc must be called before generating examples.

Overrides:

generateAllExamples in class CExampleExtractorBasic

Returns:

A list of examples.

equiv

protected boolean equiv(Mention m1,
                        Mention m2)

Determines whether the mentions are the same according to entity ID.

Parameters:

m1 - A mention.

m2 - Another mention.

Returns:

Whether the mentions have the same entity ID.
