tokenize - Tokenizer, Stop Word Removal, Stemming in Java

Question

I am looking for a class or method that takes a long string of many 100s of words and tokenizes, removes the stop words and stems for use in an IR system.

For example:

"The big fat cat, said 'your funniest guy i know' to the kangaroo..."

the tokenizer would remove the punctuation and return an ArrayList of words

the stop word remover would remove words like "the", "to", etc

the stemmer would reduce each word the their 'root', for example 'funniest' would become funny

Many thanks in advance.

Answer 1

AFAIK Lucene can do what you want. With StandardAnalyzer and StopAnalyzer you can to the stop word removal. In combination with the Lucene contrib-snowball (which includes work from Snowball) project you can do the stemming too.

But for stemming also consider this answer to: Stemming algorithm that produces real words
