Я пытаюсь использовать модуль coreference в конвейере Stanford CoreNLP, но в итоге получаю ошибку OutOfMemory в Java. Я уже увеличил размер кучи (через Run->Запустить конфигурации->VM Arguments в Eclipse) и установите для них значение -Xmx3g -Xms1g. Я даже пытался -Xmx12g -Xms4g, но это не такТ тоже не поможет. Я'используя Eclipse Juno в OS X 10.8.5 с Java 1.6 на 64-битной машине. У кого-нибудь есть идеи, что еще я мог бы попробовать?

используя пример кода с сайта (http://nlp.stanford.edu/software/corenlp.shtml):

Properties props = new Properties();
props.put("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);

String text = "Stanford University is located in California. It is a great university";

Annotation document = new Annotation(text);

pipeline.annotate(document);

List sentences = document.get(SentencesAnnotation.class);

for(CoreMap sentence: sentences) {
  for (CoreLabel token: sentence.get(TokensAnnotation.class)) {
    String word = token.get(TextAnnotation.class);
    String pos = token.get(PartOfSpeechAnnotation.class);
    String ne = token.get(NamedEntityTagAnnotation.class);       
  }

  Tree tree = sentence.get(TreeAnnotation.class);
  SemanticGraph dependencies = sentence.get(CollapsedCCProcessedDependenciesAnnotation.class);
}

Map graph = document.get(CorefChainAnnotation.class);

И я получаю ошибку:
