opennlp中的Span类不工作 [英] Span class in opennlp is not working

问题描述

我刚刚开始使用java opennlp，我试图实现一个从文件中提取城市名称的程序，但是我首先测试了一个字符串的代码，我收到一些错误
代码是

  import java.io.FileInputStream; 
 import java.io.FileNotFoundException; 
 import java.io.IOException; 
 import java.io.InputStream; 
 
 import main.java.opennlp.tools.namefind.NameFinderME; 
 import main.java.opennlp.tools.namefind.TokenNameFinderModel; 
 import main.java.opennlp.tools.util.InvalidFormatException; 
 import main.java.opennlp.tools.util.Span; 
 import opennlp.tools.tokenize.Tokenizer; 
 import opennlp.tools.tokenize.TokenizerME; 
 import opennlp.tools.tokenize.TokenizerModel; 
 import opennlp.tools.tokenize.SimpleTokenizer; 
 import opennlp.tools.sentdetect.SentenceDetectorME; 
 import opennlp.tools.sentdetect.SentenceModel; 
 
 import org.xml.sax.SAXException; 
 
 public class CityFinder {
 
 public String Tokens []; 
 
 public static void main（String [] args）throws IOException，SAXException {
 
 CityFinder toi = new CityFinder（）; 
 String cnt; 
 cnt =约翰计划在加州大学伯克利分校的电气工程专业，并与IBM进行职业生涯。 
 toi.tokenization（cnt）; 
 String cities = toi.namefind（toi.Tokens）; 
 String org = toi.orgfind（toi.Tokens）; 
 
 System.out.println（City name is：+ cities）; 
 System.out.println（组织名称为：+ org）; 
 
} 
 public String namefind（String cnt []）{
 InputStream is; 
 TokenNameFinderModel tnf; 
 NameFinderME nf; 
 String sd =; 
 try {
 is = new FileInputStream（en-ner-location.bin）; 
 tnf = new TokenNameFinderModel（is）; 
 nf = new NameFinderME（tnf）; 
 Span sp [] = nf.find（cnt）; //<  - 这里是错误
 StringBuilder fd = new StringBuilder（）; 
 int l = a.length; （int j = 0; j< l; j ++）
 
 {
 fd = fd.append（a [j] +\\\
）; 
 
} 
 sd = fd.toString（）; 
 
} catch（FileNotFoundException e）{
 
 e.printStackTrace（）; 
} catch（InvalidFormatException e）{
 
 e.printStackTrace（）; 
} catch（IOException e）{
 
 e.printStackTrace（）; 
} 
 return sd; 
} 
 
 public String orgfind（String cnt []）{
 InputStream is; 
 TokenNameFinderModel tnf; 
 NameFinderME nf; 
 String sd =; 
 try {
 is = new FileInputStream（en-ner-organization.bin）; 
 tnf = new TokenNameFinderModel（is）; 
 nf = new NameFinderME（tnf）; 
 Span sp [] = nf.find（cnt）; //<  - 这里是错误
 String a [] = Span.spansToStrings（sp，cnt）; 
 StringBuilder fd = new StringBuilder（）; 
 int l = a.length; （int j = 0; j< l; j ++）{
 fd = fd.append（a [j] +\\\
）; 
 
 
} 
 
 sd = fd.toString（）; 
 
} catch（FileNotFoundException e）{
 
 e.printStackTrace（）; 
} catch（InvalidFormatException e）{
 
 e.printStackTrace（）; 
} catch（IOException e）{
 
 e.printStackTrace（）; 
} 
 return sd; 
 
} 
 public void tokenization（String tokens）{
 
 InputStream is; 
 TokenizerModel tm; 
 try {
 is = new FileInputStream（en-token.bin）; 
 tm = new TokenizerModel（is）; 
令牌tz = new TokenizerME（tm）; 
令牌= tz.tokenize（令牌）; 
 // System.out.println（Tokens [1]）; 
} catch（IOException e）{
 e.printStackTrace（）; 
} 
} 
 
} 
  

我有错误与以下行

  Span sp [] = nf.find（cnt）; 
  

错误是

 类型不匹配：无法从opennlp.tools.util.Span []转换为main.java.opennlp.tools.util.Span [] 
  

我不知道如何在两个地方解决它。

任何建议....
提前感谢

解决方案

为什么要导入 main.java.opennlp。 * ？那些你们的班级，还是你有两个不同的地方依赖的两个单独的副本？您的项目设置方式有问题。

I am new to java opennlp and i am trying to implement a program that extracts city names from a file but i am testing my code on a string first and i get some errors the code is

        // System.out.println(Tokens[1]);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

  }

I have errors with the following line

Span sp[] = nf.find(cnt);

the error is

Type mismatch: cannot convert from opennlp.tools.util.Span[] to main.java.opennlp.tools.util.Span[]

I don't know how to solve it in both locations

Any suggestions....?? thanks in advance

解决方案

Why do you have imports of main.java.opennlp.*? Are those your classes, or do you have two separate copies of the dependency in two different places? There is something wrong with the way your project is set up.
