Hi @ALICAPRI02, Depending on your process, I would maybe suggest Filter Stopwords (Dictionary). If you'd like a good example of text processing, this Goldmine from the Academy is a nice starting point (it also uses this operator if I remember correctly): https://academy.rapidminer.com/learn/article/solution-support-ticket-classification Hope this helps!
