How to generate a wordcloud for each class attribute
Hello, I am working on a project for university and was wondering if anyone could share their expertise as i am a beginner to rapidminer.
It is a pretty straightforward project, I got a chatGPT sentiment dataset from kaggle which labels tweets as either good, bad, or neutral, and want to perform classification analysis. The only thing that I can't seem to figure out is how to generate a wordcloud for the most occuring terms. For example, I want to see what the top 20 terms that make up each sentiment label.
I would greatly appreciate any input!
Thanks
Attached is a sample from the data, and this is the XML:

Dear @rjones13,
Thanks so much for this, I was really struggling!
Thing is, I would love to know how to add weight, so I can show which terms are the most occurring in the dataset that I have since it is massive. I tried the Filter Example Range Operator, but it does not seem to be working for me, and the wordcloud only supports 500 examples.
How would I do it for the attached dataset? It is only a sample of my dataset, but it is a little bit larger than the original one.

Again, thanks a bunch Roland, I appreciate it so much!

Altair EmployeeHi @tarekq,
The weight can be added on the visualisation in the plot controls.
To overcome the limitation of up to 500 examples, I've added in a Sort operator to organise the list into descending by "Total" and then Filter Example Range to only take the first 500. It might need some more filtering, just as it seems quite dominated by https, chatgpt, and openai. Although I realise you might have already filtered these out as I took out the custom stopwords operator in my version.
Any questions let me know.
Best,
Roland

You seem to be along the right lines. The only thing you'll need to do is add a WordList to Data operator to convert the word list output of Process Documents into an ExampleSet. You can then use this to plot a word cloud:
There are further options if you'd like to add weight, and if you only want the top 20 then you might need to add a filter. Any questions let me know. I've attached the modified XML below (disabled custom stopwords and stemming, and also changed file paths).
Best,
Roland
