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,

    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,

    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,
