WordnetSynonymParser在Lucene [英] WordnetSynonymParser in Lucene

问题描述

我是Lucene的新手，我正在尝试使用WordnetSynonymParser使用wordnet同义词prolog扩展查询。以下是我现在所拥有的：

I am new to Lucene and I'm trying to use WordnetSynonymParser to expand queries using the wordnet synonyms prolog. Here is what I have till now:

public class CustomAnalyzer extends Analyzer {

@Override
protected TokenStreamComponents createComponents(String fieldName, Reader reader){
    // TODO Auto-generated method stub
    Tokenizer source = new ClassicTokenizer(Version.LUCENE_47, reader);
    TokenStream filter = new StandardFilter(Version.LUCENE_47, source);
    filter = new LowerCaseFilter(Version.LUCENE_47,filter);
    SynonymMap mySynonymMap = null;
    try {
        mySynonymMap = buildSynonym();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    filter = new SynonymFilter(filter, mySynonymMap, false);        
    return new TokenStreamComponents(source, filter);
}

private SynonymMap buildSynonym() throws IOException
{
    File file = new File("wn/wn_s.pl");
    InputStream stream = new FileInputStream(file);
    Reader rulesReader = new InputStreamReader(stream); 
    SynonymMap.Builder parser = null;
    parser = new WordnetSynonymParser(true, true, new StandardAnalyzer(Version.LUCENE_47));
    ((WordnetSynonymParser) parser).add(rulesReader);         
    SynonymMap synonymMap = parser.build();
    return synonymMap;
}
}

我收到错误方法添加（CharsRef， SynonymMap.Builder类型中的CharsRef，boolean）不适用于参数（Reader）

I get the error "The method add(CharsRef, CharsRef, boolean) in the type SynonymMap.Builder is not applicable for the arguments (Reader)"

但是，WordnetSynonymParser的文档需要add函数的Reader参数。

However, the documentation of WordnetSynonymParser expects a Reader argument for the add function.

我在这里做错了什么？
任何帮助都表示赞赏。

What am I doing wrong here? Any help is appreciated.

推荐答案

如果您看到文档说明 WordNetSynonymParser 有一个方法 add（Reader），你可能正在查看旧版本的文档。 4.7的源代码中肯定没有这种方法。从版本4.6.0开始，您要查找的方法是 WordnetSynonymParser.parse（Reader） 。

If you are seeing documentation stating that WordNetSynonymParser has a method add(Reader), you are probably looking at documentation for an older version. The method certainly isn't there in the source code for 4.7. As of version 4.6.0, the method you are looking for is WordnetSynonymParser.parse(Reader).
