Class CoNLLOutputter

java.lang.Object

edu.stanford.nlp.pipeline.AnnotationOutputter

edu.stanford.nlp.pipeline.CoNLLOutputter

public class CoNLLOutputter
extends AnnotationOutputter

Write a subset of our CoreNLP output in CoNLL format. The output can be customized to write any set of keys available with names as defined by AnnotationLookup, and in addition these specials: ID (token index in sentence, numbering from 1). The default fields currently output are:

Output fields

Field Number	Field Name	Description
1	ID (idx)	Token Counter, starting at 1 for each new sentence.
2	FORM (word)	Word form or punctuation symbol.
3	LEMMA (lemma)	Lemma of word form, or an underscore if not available.
4	POSTAG (pos)	Fine-grained part-of-speech tag, or underscore if not available.
5	NER (ner)	Named Entity tag, or underscore if not available.
6	HEAD (headidx)	Head of the current token, which is either a value of ID or zero ('0'). This is underscore if not available.
7	DEPREL (deprel)	Dependency relation to the HEAD, or underscore if not available.
