    hello @gham - this is called "sentiment analysis" and you can find LOTS of videos on this topic on our YouTube channel: https://www.youtube.com/user/RapidIVideos/search?view_as=subscriber&query=sentiment

     

    There are no word cloud visualizations for RapidMiner but many resources on the internet. Just Google "word cloud visualization".
