我如何从斯坦福大学的情感分析中找出5个积极性值？

Question

我希望传递一个字符串来解析并返回具有最高评级的数字（1-5）。

例如，这将返回2：

Answer 1

我假设您正在使用带有sentiment annotator的Stanford CoreNLP管道。

此注释器在每个名为SentimentCoreAnnotations.ClassName的句子上设置注释。只需检索此值:(未经测试的示例）

Properties props = new Properties();
props.setProperty("annotators", "tokenize, ssplit, pos, parse, sentiment");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);

// read some text in the text variable
String text = ... // Add your text here!

// 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) {
  String sentimentLabel = sentence.get(SentimentCoreAnnotations.ClassName.class);

  // ...
}
