Selecting Tokenized Attributes

gn582gn582 Member Posts: 2 Contributor I
Hey guys,

Using Rapidminer for the first time for one of my university subjects. I'm trying to make a decision tree that uses the least_square criterion as it has a numerical attribute as the label.

The data deals with Youtube attributes and I am trying to tokenize the tag column (which I can successfully do) and then select each tag individually using the "Select Attribute" operator so that I can input the data into the decision tree and have the number of likes column be the label for the decision tree.ย 

The problem is when I process the tag data and tokenize it, I can only select the attribute "text" rather than each token individually. Is there a way around this or a way I can select each token to input into the data set?

Sorry if I worded it confusingly,

Thanks for the help!

    Hi @gn582,

    If I good understand, you want select only the token attributes and exclude the "text" attribute ?

    In this case :ย 
    ย - select attribute filter type = single
    ย - select your "text" attribute
    AND
    ย - check invert selection
