是否有Porter2 stemmer的java实现 [英] Is there a java implementation of Porter2 stemmer

问题描述

你知道Porter2词干分析器的任何java实现（或者用java编写的更好的词干分析器）吗？我知道这里有一个java版本的Porter（不是Porter2）：

Do you know any java implementation of the Porter2 stemmer(or any better stemmer written in java)? I know that there is a java version of Porter(not Porter2) here :

http://tartarus.org/~martin/PorterStemmer/java.txt

但是 http://tartarus.org/~martin/PorterStemmer/ 作者提到Porter有点过时并建议使用Porter2，可在

but on http://tartarus.org/~martin/PorterStemmer/ the author mentions that the Porter is bit outdated and recommends to use Porter2, available at

http ：//snowball.tartarus.org/algorithms/english/stemmer.html

然而，我的问题是这个Porter2是用雪球写的（我之前从未听说过，所以对此一无所知。我正在寻找的是它的java版本。

However, the problem with me is that this Porter2 is written in snowball(I never heard of it before, so don't know anything about it). What I am exactly looking for is a java version of it.

谢谢。非常感谢你的帮助。

Thanks. Your help will he highly appreciated.

推荐答案

Snowball算法以 Java下载

The Snowball algo is available as a Java download

来自 snowball.tartarus.org ：

2002年2月 - Java支持Richard有
修改了雪球代码生成器
以生成Java输出以及ANSI
C输出。这意味着纯Java
系统现在可以使用snowball
stemmers。

Feb 2002 - Java support Richard has modified the snowball code generator to produce Java output as well as ANSI C output. This means that pure Java systems can now use the snowball stemmers.

这就是你想要的，对吗？

This is what you want, right?

您可以像这样创建一个实例：

You can create an instance of it like so:

  Class stemClass = Class.forName("org.tartarus.snowball.ext." + lang + "Stemmer");
  stemmer = (SnowballProgram) stemClass.newInstance();
  stemmer.setCurrent("your_word");
  stemmer.stem();
  String your_stemmed_word = stemmer.getCurrent();
