[JAVA] Try parsing English with Stanford CoreNLP

Analyze English sentences using Stanford CoreNLP. (Japanese is not supported) https://stanfordnlp.github.io/CoreNLP/

The code is as follows.

package pkg;

import java.util.List;
import java.util.Properties;

import edu.stanford.nlp.ling.CoreAnnotations.AfterAnnotation;

	public static void main(String[] args) {
		String text = "I have a red Nissan car.";

		Properties properties = new Properties();
		properties.setProperty("annotators", "tokenize, ssplit, pos, depparse");

				printWord(root, graph, 0);
			}
		}
	}

	public static void printWord(IndexedWord word, SemanticGraph graph, int tab) {

		System.err.println("---");

		}
	}
}
