Question

How to find out the verbs in the text with part of speech tags using the constrains in Stanford CoreNLP.

For example, in the text

Supplementary_NNP Data_NNP are_VBP available_JJ at_IN NAR_NNP Online_NNP ._. 

I want to find out the verb of the sentence which must contain the word `online`

I have many thses sentences, which has been added with part of speech suffix to each word. And I would like to use regex or other means to find out verb of the sentence which contains specific word.

Answer:

Code to extract verbs using NLP libraries in Java :

import edu.stanford.nlp.ie.util.RelationTriple;
import edu.stanford.nlp.ling.CoreAnnotations;
import edu.stanford.nlp.ling.CoreAnnotations.TextAnnotation;
import edu.stanford.nlp.pipeline.Annotation;
import edu.stanford.nlp.pipeline.StanfordCoreNLP;
import edu.stanford.nlp.naturalli.NaturalLogicAnnotations;
import edu.stanford.nlp.util.CoreMap;
import java.util.Collection;
import java.util.Properties;

public class OpenIE {

    public static void main(String[] args) {
        Properties props = new Properties();
        props.setProperty("annotators", "tokenize,ssplit,pos,lemma,depparse,natlog,openie");
        StanfordCoreNLP pipeline = new StanfordCoreNLP(props);

        // Annotate your sentences
        Annotation doc = new Annotation("This person is trust worthy. This person is non judgemental. This person is well spoken.");
        pipeline.annotate(doc);

        // Loop over sentences in the document
        for (CoreMap sentence : doc.get(CoreAnnotations.SentencesAnnotation.class)) {
          // Get the OpenIE triples for the sentence
          Collection<RelationTriple> triples = sentence.get(NaturalLogicAnnotations.RelationTriplesAnnotation.class);
          // Print the triples
          for (RelationTriple triple : triples){
              triple.object.forEach(object -> System.out.print(object.get(TextAnnotation.class) + " "));
              System.out.println();
          }
       }
    }
}

Output :

trust worthy non judgemental judgemental well spoken spoken ... Program finished with exit code o Press ENTER to exit console. I
