spring如何在Java中找到给定段落的标题

Question

我想创建一些功能，可以为我提供给定聊天对话或段落的标题。 这里的标题是“聊天内容”或段落内容

我尝试了StanfordCoreNLP来实现句子标记化和句子识别器。但我的主要目标是从段落或输入文本中搜索一些关键字，并确定输入文本的实际标题或标题是什么

我试过这个-

public class Pipeline {
    private static Properties properties;
    private static String propertiesName = "tokenize, ssplit, pos, lemma, parse, sentiment, ner";
    private  static StanfordCoreNLP stanfordCoreNLP;

    private Pipeline(){
    }
    static {
        properties = new Properties();
        properties.setProperty("annotators", propertiesName);
    }
    public static StanfordCoreNLP getPipeline(){
        if(stanfordCoreNLP == null){
            stanfordCoreNLP = new StanfordCoreNLP(properties);
        }
        return stanfordCoreNLP;
    } }

句子识别器。爪哇-

public class SentenceRecognizer {
    public static void main(String[] args) {
      StanfordCoreNLP stanfordCoreNLP= Pipeline.getPipeline();

      String text = "Hey Iam Jhon. Iam doing Math. I like coffee ";
        CoreDocument coreDocument = new CoreDocument(text);
        stanfordCoreNLP.annotate(coreDocument);
       List<CoreSentence> sentences= coreDocument.sentences();
       for(CoreSentence sentence: sentences){
           System.out.println(sentence.toString());
       }
    }
}

输出-

Hey Iam Jhon.
Iam doing Math.
I like coffee

同样，我也实现了标记化、词性、情绪分析和引理

我想要的输出- 示例段落为输入-

If you could make a holiday, what would it be like? What traditions would it have? What would people eat on your holiday?

预期输出-假日

任何人都可以在逻辑上帮助我，使用所有这些从这个字符串生成标题。请帮忙
