Consider the following sequence to create a pipeline:
String text = "The robber took the cash and ran.";
Properties props = new Properties();
props.put("annotators",
"tokenize, ssplit, pos, lemma, ner, parse, dcoref");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
We get the following output for the annotation process. We can see each annotator as it is
applied:
