我试图使用Stanford Corenlp工具包来注释文本(使用Netbeans而不是命令行),我尝试使用http://nlp.stanford.edu/software/corenlp.shtml#Usage上提供的代码(使用Stanford CoreNLP API) . 问题是:有谁能告诉我我怎么做获取文件中的输出,以便我可以进一步处理它?
我已经尝试将图形和句子打印到控制台,只是为了查看内容 . 这样可行 . 基本上我需要的是返回带注释的文档,这样我就可以从我的主类中调用它并输出一个文本文件(如果可能的话) . 我正在尝试查看stanford corenlp的API,但由于缺乏经验,我不知道返回此类信息的最佳方法是什么 .
这是代码:
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);

一旦您拥有代码示例中显示的任何或所有自然语言分析,您需要做的就是以普通的Java方式将它们发送到文件,例如,使用FileWriter进行文本格式输出 . 具体来说,这是一个简单的完整示例,显示发送到文件的输出(如果您给它适当的命令行参数):
