Hello all,
I have collected some comments from a feedback I received, I put them in a doc, and now I would like to extract some themes or topics from these comments. To categorise the comments in a way into different themes accoriding to the frequency of the words maybe? Is this sth that can be easily done?
Many thanks,
Dimitris

Hi Martin,
Thank you for your reply, I can find the Linear Discriminant Analysis operator, but I cannot find the Extract topics, could you please give me more guidance?
Thank you very much and I am sorry I am not yet knowledgable of Rapid Miner.
Best, Dimitris
Hi @dparaskevop,
To use the operator Extract Topics from Document (LDA), you have to install first the last version
of Operator Toolbox extension from the Marketplace.
NB : In this case, LDA means Latent Dirichlet Allocation (and not Linear Discriminent Analysis).
I hope it helps,
Regards,
Lionel
Thank you very much, I found it.
I am sorry to bombard you with questions, now how can I feed the word document I have into the Extract Topics from Document (LDA)?
Many thanks,

@dparaskevop I think the community search function works well.
