Word2VEC java版本的一个实现。
示例代码:
package com.kuyun.document_class; import java.io.BufferedReader; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.UnsupportedEncodingException; import java.util.List; import org.ansj.domain.Term; import org.ansj.splitWord.analysis.ToAnalysis; import com.alibaba.fastjson.JSONObject; import com.ansj.vec.Learn; import com.ansj.vec.Word2VEC; import love.cq.util.IOUtil; import love.cq.util.StringUtil; public class Word2VecTest { private static final File sportCorpusFile = new File("corpus/result.txt"); public static void main(String[] args) throws IOException { File[] files = new File("corpus/sport/").listFiles(); //构建语料 try (FileOutputStream fos = new FileOutputStream(sportCorpusFile)) { for (File file : files) { if (file.canRead() && file.getName().endsWith(".txt")) { parserFile(fos, file); } } } //进行分词训练 Learn lean = new Learn() ; lean.learnFile(sportCorpusFile) ; lean.saveModel(new File("model/vector.mod")) ; //加载测试 Word2VEC w2v = new Word2VEC() ; w2v.loadJavaModel("model/vector.mod") ; System.out.println(w2v.distance("姚明")); ; } private static void parserFile(FileOutputStream fos, File file) throws FileNotFoundException, IOException { // TODO Auto-generated method stub try (BufferedReader br = IOUtil.getReader(file.getAbsolutePath(), IOUtil.UTF8)) { String temp = null; JSONObject parse = null; while ((temp = br.readLine()) != null) { parse = JSONObject.parseObject(temp); paserStr(fos, parse.getString("title")); paserStr(fos, StringUtil.rmHtmlTag(parse.getString("content"))); } } } private static void paserStr(FileOutputStream fos, String title) throws IOException { List<Term> parse2 = ToAnalysis.parse(title) ; StringBuilder sb = new StringBuilder() ; for (Term term : parse2) { sb.append(term.getName()) ; sb.append(" "); } fos.write(sb.toString().getBytes()) ; fos.write("\n".getBytes()) ; } }
