Создать объект CoreNLP с Явой

Question

public static void main(String[] args) { 
    Properties props = new Properties(); 
props.put("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref"); 
StanfordCoreNLP pipeline = new StanfordCoreNLP(props); 

// read some text in the text variable 
String text = "the quick fox jumps over the lazy dog"; 

// create an empty Annotation just with the given text 
Annotation document = new Annotation(text); 

// run all Annotators on this text 
pipeline.annotate(document); 

// these are all the sentences in this document 
// a CoreMap is essentially a Map that uses class objects as keys and has values with custom types 
List<CoreMap> sentences = document.get(SentencesAnnotation.class); 

for(CoreMap sentence: sentences) { 
    // traversing the words in the current sentence 
    // a CoreLabel is a CoreMap with additional token-specific methods 
    for (CoreLabel token: sentence.get(TokensAnnotation.class)) { 
    // this is the text of the token 
    String word = token.get(TextAnnotation.class); 
    // this is the POS tag of the token 
    String pos = token.get(PartOfSpeechAnnotation.class); 
    // this is the NER label of the token 
    String ne = token.get(NamedEntityTagAnnotation.class);  
    } 

    // this is the parse tree of the current sentence 
    Tree tree = sentence.get(TreeAnnotation.class); 

    // this is the Stanford dependency graph of the current sentence 
    SemanticGraph dependencies = sentence.get(CollapsedCCProcessedDependenciesAnnotation.class); 
} 

// This is the coreference link graph 
// Each chain stores a set of mentions that link to each other, 
// along with a method for getting the most representative mention 
// Both sentence and token offsets start at 1! 
Map<Integer, CorefChain> graph = 
    document.get(CorefChainAnnotation.class); 
} 

}

Я хочу, чтобы запустить свою программу, но я получаю эту ошибку

я не знаю, как я могу увеличить размер кучи или эту ошибку relateto к другой проблеме что я не могу понять. кто-нибудь может мне помочь? (извините, мой английский не очень хорош)

Answer 1

Если ваш проект java-проект ---> Щелкните правой кнопкой мыши по проекту ---> Выбрать свойства ---> Нажмите «Пуск» -> с правой стороны вы увидите параметры VM, там вам нужно ввести настройки кучи.

Пример:

-Xmx512m 

Примечание: Если 512 не работает, увеличить его до 1024 и попробовать.
