How do I use LDA for a single column in an Excel File
Hello Rapidminer Community,
First of all a big THANK YOU to anyone who helps, I´m currently writing my Thesis and I´m quite new to RAPIDMINER but you definetly rock!
I´m trying to use LDA for a single Column in an Excel File, so the Read Excel Operator is currently only importing one Column into the software which is different texts in 400 rows. Currently I´m using the process shown in the pictures I attached below, as it is quiet similar to the process which is shown in a Youtube Tutorial by Nasir Soft called: "13 -Topic Modeling and Latent Dirichlet Allocation (LDA) | Twitter Mining | Rapidminer Tutorial". I´m not allowed to post Links yet, but I will attach his process also (it is the fourth picture).
I think the processes are quite similar except for the fact, that I´m using the "Process Documents" Operator to preprocess the text data (Tokenizing, Stemming...).
Does anybody know what I´m doing wrong as i dont get any results.
