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.

    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,

    Many thanks,
