如何使用OpenNLP从文本中获取位置？

Question

我使用组块来标记数据，并从文本中获取位置。最初，我尝试从next中提取名词短语，当我们使用名词短语名称（也被称为名词短语）时，它无法使用。然后我转移到核心nlp的位置，我试着运行下面的代码

 * @param args the command line arguments
 */
public static void main(String[] args) {
    // TODO code application logic here
    try {

InputStream inputStreamTokenizer=new FileInputStream（"文本文档中的D：\project\关系提取\Libraray\解析/en-token.bin"）；TokenizerModel TokenModel=new TokenizerModel（inputStreamTokenizer）；

  //String paragraph = "Mike and Smith are classmates"; 
  String paragraph = "Tutorialspoint is located in Hyderabad"; 

  //Instantiating the TokenizerME class 
  TokenizerME tokenizer = new TokenizerME(tokenModel); 
  String tokens[] = tokenizer.tokenize(paragraph); 

  //Loading the NER-location moodel 
  InputStream inputStreamNameFinder = new 
     FileInputStream("D:\\project\\Relation Extraction in Text Document\\Libraray\\parsing/en-ner-location.bin");       
  TokenNameFinderModel location = new TokenNameFinderModel(inputStreamNameFinder); 

  //Instantiating the NameFinderME class 
  NameFinderME nameFinder;      
        nameFinder = new NameFinderME(location);

  //Finding the names of a location 
  Span nameSpans[] = nameFinder.find(tokens);        
  //Printing the spans of the locations in the sentence 
 for(Span s: nameSpans)        
     System.out.println(s.toString()+"  "+tokens[s.getStart()]);

我得到了一个错误：“java.lang.UnsupportedOperationException:还不受支持。”

“nameFinder=new NameFinderME（location）；”处的错误符号说“exmp.TokenNameFinderModel无法转换为opennlp.tools.namefind.TokenNameFinderModel”的原因是什么

您有不正确的导入，这里是一个工作版本：

import java.io.FileInputStream;
import java.io.InputStream;

import opennlp.tools.namefind.NameFinderME;
import opennlp.tools.namefind.TokenNameFinderModel;
import opennlp.tools.tokenize.TokenizerME;
import opennlp.tools.tokenize.TokenizerModel;
import opennlp.tools.util.Span;

输出：[4..5）海得拉巴位置
