Lemmatization algorithm?

Question

Algorithms

Is there a lemmatization algorithm (albeit simplified and inaccurate) for the Russian language or a library for the JVM?

Answer 1

If stemming does not suit you and you need to be more precise, look at AOT (aot.ru) there are already implemented lemmatization algorithms, open codes and the theory is described.

Answer 2

You may be satisfied with the Russian morphology analyzer for Lucene: code.google.com/p/russianmorphology/
Lucene itself is not required.

//опустим шаблонный код

private LuceneMorphology luceneMorphRus;
private String str = "Красивая"; 

// это лучше обернуть в синглтон, операция дорогая!
luceneMorphRus = ResourceLoader.getLuceneRussianMorphology();
List<String> wordInfo = luceneMorphR.getMorphInfo(str);

//анализируем wordInfo

Answer 3

So like Porter's stemmer.
Here is an example on a javka:
