分析器 OpenNLP

7 分析器

功能介绍：尝试解析器最简单的方法是在命令行工具。该工具仅用于演示和测试。请从我们网站上的英文分块解析器模型，并用以下命令启动解析工具。

代码实现：

package package01;

import opennlp.tools.cmdline.parser.ParserTool;
import opennlp.tools.parser.Parser;
import opennlp.tools.parser.ParserFactory;
import opennlp.tools.parser.ParserModel;
import opennlp.tools.util.InvalidFormatException;

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

public class Test07 {

    public static void main(String[] args) throws IOException {
        Test07.Parse();
    }

    /**

}

　　

结果

(TOP (S (NP (NN Programcreek)) (VP (VBZ is) (NP (DT a) (ADJP (RB very) (JJ huge) (CC and) (JJ useful)))) (. website.)))
