Quote Annotator get author - stanford-nlp

Question

In the following text:
John said, "There's an elephant outside the window."
Is there a simple way to figure out that the quote "There's an elephant outside the window." belongs to John?

Answer 1

We've just added a module for handling this.
You'll need to get the latest code from GitHub.
Here is some sample code:
package edu.stanford.nlp.examples;
import edu.stanford.nlp.coref.*;
import edu.stanford.nlp.coref.data.*;
import edu.stanford.nlp.ling.CoreAnnotations;
import edu.stanford.nlp.util.*;
import edu.stanford.nlp.pipeline.*;
import java.util.*;
public class QuoteAttributionExample {
public static void main(String[] args) {
Annotation document =
new Annotation("John said, \"There's an elephant outside the window.\"");
Properties props = new Properties();
props.setProperty("annotators", "tokenize,ssplit,pos,lemma,ner,entitymentions,quote,quoteattribution");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
pipeline.annotate(document);
for (CoreMap quote : document.get(CoreAnnotations.QuotationsAnnotation.class)) {
System.out.println(quote);
System.out.println(quote.get(QuoteAttributionAnnotator.MentionAnnotation.class));
}
}
}
This is still under development, we will probably add some code to make it easier to get the actual text span that links to the quote soon.
