Getting output in the desired format using TokenRegex

Question

I am using TokensRegex for rule based entity extraction. It works well but I am having trouble getting my output in the desired format. The following snippet of code gives me an

Answer 1

I managed to get output in desired format.

Annotation document = new Annotation();

//use the pipeline to annotate the document we created
pipeline.annotate(document);
List sentences = document.get(SentencesAnnotation.class);

//Note- I doesn't put environment related stuff in rule file.
Env env = TokenSequencePattern.getNewEnv();
env.setDefaultStringMatchFlags(NodePattern.CASE_INSENSITIVE);
env.setDefaultStringPatternFlags(Pattern.CASE_INSENSITIVE);


CoreMapExpressionExtractor extractor = CoreMapExpressionExtractor
      .createExtractorFromFiles(env, "test_degree.rules");

for (CoreMap sentence : annotation.get(CoreAnnotations.SentencesAnnotation.class)) {
      List matched = extractor.extractExpressions(sentence);
      for(MatchedExpression phrase : matched){
      // Print out matched text and value
      System.out.println("MATCHED ENTITY: " + phrase.getText() + " VALUE: " + phrase.getValue().get());
      }
    }

Output:

MATCHED ENTITY: Technical Skill VALUE: SKILL
