Hi @eiman

The general answer is yes. I may suggest you to try out LDA operator from the Operator Toolbox extension, which is capable of unsupervised classification texts by topic. Another approach to try is to analyze word frequency distribution, here's a good post to start with: https://community.rapidminer.com/discussion/31744/calculating-word-frequency-using-rapidminer
