Create themes from a document

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,

Cheers,

Martin

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,

Dimitris

@dparaskevop I think the community search function works well.

Hi,

just click on the Operator and press f1. The tutorial processes are under "Description".
