Constructor Detail

ChunkedExtraction

public ChunkedExtraction(ChunkedSentence sent,
                 edu.washington.cs.knowitall.commonlib.Range range)

Constructs a new ChunkedExtraction object representing range in the sentence sent. range must be a subset of [0, sent.getLength() ).

Parameters:

sent - the source sentence.

range - the subsequence of sent that this extraction will represent.

ChunkedExtraction

public ChunkedExtraction(ChunkedSentence sent,
                 edu.washington.cs.knowitall.commonlib.Range range,
                 String string)

Constructs a new NpChunkedExtraction object representing range in the sentence sent. range must be a subset of [0, sent.getLength()).

Parameters:

sent - the source sentence.

range - the subsequence of sent that this extraction will represent.

string - a string representation of the relation part, usually different than just the subsequence in the sentence.
