"arabic text classification"

Hi,
RapidMiner does not care about the language of the texts. All texts, that can be separated in single words, might be used to build a bag of words.
Just use the text plugin as described in its samples.

Hi,
I presonly worked with it , just add utf8 , or the word unicode in the encoding field

Hi
If I can use arabic text classification, why there is an english and german stemmers

Thank you

Mmm, a tough one, don't suppose it could be for English or German text classification? Just a wild and uninspired guess.

you  dont need to use the german or the english stemmers ,
Rapid miner does not support arabic stemming ,
what you can do is either use n-grams  or stem the text files outside rapidminer

helloo

 i am beginner   can you help me please to  change  the encoding   to can work with arabic textes !
