Is lemmatization available somehow? Also POS tagger not tagging correctly in German.

Hello there. I am absolutely new to KNIME and i am pretty new to text processing in general.

So i know there is some difference between Stemming and Lemmatization of words, although im not sure if i totally understand it. I found the Snowball Stemmer node, but it does not work that great with the language my files are in (german). Thats why i wanted to try Lemmatization, but so far i didnt find any node for it and google doesnt help either.

Also, the POS Tagger node tags some of the verbs in the text as NN or NNS, does anyone know why that could happen?

Please keep in mind that i am new to all of this, sorry therefore.

Thanks in advance for any help.

Regards, myusername
