Hi, I recently started to use rapidminer and I am having troubles with some operators regarding text processing, because the language that I am working with is spanish.

The operators that I would like to use are:

Stemming
tokenize linguistic
filter stopwords

Are these operators available for spanish texts. ??

    Still no Filter Stopwords available in Spanish though, right? :(

    Actually there are Spanish stopwords you can download from the internet and add to your process using the Filter Stopwords (Dictionary). 
    Just follow the operator documentation and create a file with one Spanish word per line and use that. 

    Here's a short example using the stopwords listed here: http://www.ranks.nl/stopwords/spanish
