Create themes from a document

dparaskevop

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,

have a look at the Extract Topics from Documents (LDA) operator which is part of operator toolbox. this should do it.

 

Cheers,

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.

Hi,

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