hello @ahootanha some quick recommendations for you:
• Post your XML process here in this thread (see https://youtu.be/KkgB5QXWXJ8 and "Read Before Posting" on right when you reply)
• Attach your dataset if possible (use a fictionalized version if there are privacy concerns)
• Make sure you have all necessary extensions installed (see https://youtu.be/pjBqG3xtXx4)

Hello @ahootanha so perhaps you misunderstood. I am sure you searched and did not find an answer. But PLEASE post your process and your dataset. This is the part that makes it much easier for us to help.

Hello
Thank you for your attention
I get data with the search twitter operator. And I want to remove the symbols from tweets in the preprocessing stage.
Please guide. How do I perform preprocessing for the analysis of emotions in RapidMiner? Thanks & Regards

hello @ahootanha I hear your question and I am able and willing to help. But if you don't (a) post your process, and (b) post your dataset, I cannot. I'm not sure how many different ways I can explain the same thing...

Hi, I want to remove the symbols like @, #,%, $ from the text of the Twitter tweets. But I do not know how to write a regular expression in the unconnected operator.
Thanks for helping me write a regular expression

sgenzer

so there are good RegEx editors built into some operators, e.g. the Replace operator. There you can find some pre-made RegEx expressions such as the one you wish to use:
