Hello
I want to extract the same topics from the sentences, and cluster them according to the similarity of the subject
I made this model but it has an error
Someone send me the correct process?
Thank you very much

I ran into something similar once using another operator. Then it was because one of my words was 'text', and this was the same as the label used by the process (I think)

Fixed it then by first replace all text values in my original content with txt, and in the end doing the opposite.

 

Not sure if this is similar but worth a try...
