I have suggestions (text I) :
Tom is a smart boy. He knows a lot of things.
I want to change He in the second sentence of Tom , so the final sentences will become (text II) :
Tom is a smart boy. Tom knows a lot.
I wrote some code, but my coref object is always null .
In addition, I do not know what to do next to get the right result.
String text = "Tom is a smart boy. He know a lot of thing.";
Annotation document = new Annotation(text);
Properties props = new Properties();
props.put("annotators", "tokenize, ssplit, pos, parse, lemma, ner, dcoref");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
pipeline.annotate(document);
List<Pair<IntTuple, IntTuple>> coref = document.get(CorefGraphAnnotation.class);
, , II I.
PS: Stanford CoreNLP 1.3.0.
