在Eclipse上运行时，Stanford CoreNlp错误“ java.lang.OutOfMemoryError：超出了GC开销限制”

Question

I am getting this error

java.lang.OutOfMemoryError: GC overhead limit exceeded

while trying to run the following code. Can anybody tell me what to do. Also I want link to good Standford CoreNlp tutorial.

package stanfordnlp;
import java.io.*;
import java.util.*;
import edu.stanford.nlp.io.*;
import edu.stanford.nlp.ling.*;
import edu.stanford.nlp.pipeline.*;
import edu.stanford.nlp.trees.*;
import edu.stanford.nlp.util.*;

public class BaseStanfordNlp {

public static void main(String[] args) throws IOException {
PrintWriter out;
if (args.length > 1) {
  out = new PrintWriter(args[1]);
} else {
  out = new PrintWriter(System.out);
}
PrintWriter xmlOut = null;
if (args.length > 2) {
  xmlOut = new PrintWriter(args[2]);
}

StanfordCoreNLP pipeline = new StanfordCoreNLP();
Annotation annotation;
if (args.length > 0) {
  annotation = new Annotation(IOUtils.slurpFileNoExceptions(args[0]));
} else {
  annotation = new Annotation("Kosgi Santosh sent an email to Stanford University. He didn't get a reply.");
}

pipeline.annotate(annotation);
pipeline.prettyPrint(annotation, out);
if (xmlOut != null) {
  pipeline.xmlPrint(annotation, xmlOut);
}
// An Annotation is a Map and you can get and use the various analyses individually.
// For instance, this gets the parse tree of the first sentence in the text.
List<CoreMap> sentences = annotation.get(CoreAnnotations.SentencesAnnotation.class);
if (sentences != null && sentences.size() > 0) {
  CoreMap sentence = sentences.get(0);
  Tree tree = sentence.get(TreeCoreAnnotations.TreeAnnotation.class);
  out.println();
  out.println("The first sentence parsed is:");
  tree.pennPrint(out);
}
}

}

You'll need to use more memory when you run your code. Here is a link about adding memory in Eclipse:

Here is a link for Stanford CoreNLP documentation:
