"How to get a Word list from select by weights operator?"

hi guys,

 

i built model for sentiment analysis, i used Weight by Correlation and Select by Weights operations in my model. 

i training my model with dataset of 1950 rows. i want to test my model with 3000 rows using apply model with wordlist generated from select by Weights not from wordlist that generated from process document from data operator.

 

my question how to get Word list from select by weights? Is there any macro or script do that?

    Hi,

     

    have a look at this article, that should do it: https://community.rapidminer.com/t5/RapidMiner-Studio-Knowledge-Base/Text-Mining-and-the-Word-List/ta-p/31723

     

    If not - have a look a look on Data to Weights. It creates a weight vector which might help you.

    thanks for your reply,

     

    first solution i mention about it in my question, it gives all words but i want sub list generate form exp of operator select by weight.

    and second solution Weights to Data it gives all  words same as wor of operator processing, also there is no operator convert to Word list

    from Data or weight or any thing.

     

    i hope this pic clear my ideaRM1.JPG

     

    i want red box operator, macro or script convert exp set to word list or regular attribute Names  to word list.

     

    thanks, i am appreciated it.

    Hi,

     

    i think you need to combine the two things. Use the wordlist generated in the upper stream for the lower and use the select by Weights in the lower and the upper on the same weights.

     

    By the way, maybe you can ignore the second step. additional attributes are no problem while applying a learner. They will just get ignored.

    when  i use select by weight in lower i get new features not equal training features, i need to get the traing features because i get less accuracy when i take all words.

    So you're going to need two new Process Documents from Data operators. After the Select by Weights operator put another Process Documents from Data operator and then ger rid of the Process  Documents operator in the lower branch. Replace it with a copy of the new Doc from Data operator. Connect the Wordlist outputs together. Should work then.

    i try your solution. i got the all features not training features
