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
import java.io.FileInputStream;
import java.io.FileNotFoundException;

public static void main(String[] args) throws IOException, SAXException {

String cnt;
cnt="John is planning to specialize in Electrical Engineering in UC Berkley and pursue a career with IBM.";
toi.tokenization(cnt);
String cities = toi.namefind(toi.Tokens);

Tokenizer tz = new TokenizerME(tm);
Tokens = tz.tokenize(tokens);
// 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.
