我正在学习使用lucene。我写了一个简单的程序来测试Lucene的分析,如:Lucene的AnalyzerUtil错误
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.analysis.WhitespaceAnalyzer;
import org.apache.lucene.analysis.SimpleAnalyzer;
import org.apache.lucene.analysis.StopAnalyzer;
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.util.Version;
import org.apache.lucene.wordnet.AnalyzerUtils;
import java.io.IOException;
public class AnalyzerDemo {
private static final String[] examples = {
"The quick brown fox jumped over the lazy dog",
"XY&Z Corporation - [email protected]"
};
private static final Analyzer[] analyzers = new Analyzer[] {
new WhitespaceAnalyzer(),
new SimpleAnalyzer(),
new StopAnalyzer(Version.LUCENE_30),
new StandardAnalyzer(Version.LUCENE_30)
};
public static void main(String[] args) throws IOException {
String[] strings = examples;
if (args.length > 0) {
strings = args;
}
for (String text : strings) {
analyze(text);
}
}
private static void analyze(String text) throws IOException {
System.out.println("Analyzing \"" + text + "\"");
for (Analyzer analyzer : analyzers) {
String name = analyzer.getClass().getSimpleName();
System.out.println(" " + name + ":");
System.out.print(" ");
AnalyzerUtils.displayTokens(analyzer, text);
System.out.println("\n");
}
}
}
,但我得到了以下错误:
AnalyzerDemo.java:7: package org.apache.lucene.wordnet does not exist
import org.apache.lucene.wordnet.AnalyzerUtils;
^
AnalyzerDemo.java:35: cannot find symbol
symbol : variable AnalyzerUtils
location: class AnalyzerDemo
AnalyzerUtils.displayTokens(analyzer, text);
^
Note: AnalyzerDemo.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

我认为图书馆共发现或AnalyzerUtils不可用。我怎样才能安装这部分的lucene?你有什么想法?为什么失踪?我已经安装了lucene 3.5.0。
所以,我该怎么办,如果我需要的文档(文档词向量)和词频的单词列表? – orezvani 2012-01-05 08:24:10
创建一个新问题,可能有其他人想要做同样的事情 – milan 2012-01-05 10:45:30
