使用StanfordCoreNLP管道而不是AnnotationPipeline提取日期

Question

当我使用StanfordCoreNLP的SUTime功能，使用其留档中给出的代码，其中涉及使用AnnotationPipeline创建管道对象时，我能够成功地从字符串中提取TIME。

我还尝试了@StanfordNLPHelp在这个链接中建议的解决方案：使用StanfordCoreNLP管道的日期

但错误仍然存在：

Answer 1

相同的TIMEX3格式，这是由于使用：
obj.get（TimeExpress. Annotation.class）. getTemporal（）---

Answer 2

标准的ner注释器将运行SUTime。有关Java API信息，请参见以下链接：

基本示例：

import edu.stanford.nlp.ling.*;
import edu.stanford.nlp.ie.util.*;
import edu.stanford.nlp.pipeline.*;
import edu.stanford.nlp.semgraph.*;

    // canonical speaker of quote
    System.out.println("Example: canonical speaker of quote");

  }

}

如果只需要日期，可以在ner之后删除注释器。
