public void readTreebank(ITreeBank tb)
                  throws IOException

Fills a ITreeBank from content provided by a Reader.

Specified by:

readTreebank in interface ITreebankReader

Parameters:

tb -

readSequenceScore

private void readSequenceScore(ITree t,
                               String line)

readStructure

private void readStructure(ITree t,
                           String line)

Parses the structure of a ITree from String line. The (constituent-) structure must be formatted in ABL- or ABL4J-syntax.

Parameters:

t - The tree that will be enriched with structural information

line - The structural information to parse

readProbability

private void readProbability(IConstituent cons,
                             String prob)

readSentence

private void readSentence(ITree t,
                          String currentLine)

Parses the words of a sentence from String currentLine and adds the information to ITree t.

Parameters:

t - the tree

currentLine -

readWord

private IWord readWord(String currentLine)

Parses a single IWord from String currentLine. The parsed Word is registered within an instance of WordMapping.

Parameters:

currentLine - the String which contains the ISentence.
