CoNLLColumnFormatReader

public CoNLLColumnFormatReader(String corpus,
                               String section,
                               String columnFile,
                               String predicateArgumentViewName,
                               TextAnnotationBuilder textAnnotationBuilder)
                        throws Exception

Initialize the reader.

Parameters:

corpus - The name of the corpus

section - The section of WSJ that is to be read. This is largely inconsequential, and is used only to assign identifiers to the TextAnnotation objects.

columnFile - The file containing the column format data

predicateArgumentViewName - The name of the predicate argument view. For consistency, use ViewNames#SRL_VERB for verb SRL_VERB and ViewNames#SRL_NOM for SRL_NOM.

Throws:

Exception

Method Detail

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception

hasNext

public boolean hasNext()

Description copied from class: AnnotationReader

is there another annotation object to return?

Specified by:

hasNext in interface Iterator<TextAnnotation>

Specified by:

hasNext in class AnnotationReader<TextAnnotation>

Returns:

'true' if there is at least one more annotation, 'false' otherwise

reset

public void reset()

Description copied from class: AnnotationReader

override this to conform to whatever the derived class's state mechanism requires.

Specified by:

reset in interface IResetableIterator<TextAnnotation>

Overrides:

reset in class AnnotationReader<TextAnnotation>

next

public TextAnnotation next()

return the next annotation object. Don't forget to increment currentAnnotationId.

Specified by:

next in interface Iterator<TextAnnotation>

Specified by:

next in class AnnotationReader<TextAnnotation>

Returns:

an annotation object.
