Select Terms

Hi, Everybody

I don't if the topic is in correct place. Anyway...

Is it possible to make a filtering of the terms as follows in RapidMiner?

Supose:

NA - Number of occurrence of a word in Class A
NB - Number of occurrence of a word in Class B
NC - Number of occurrence of a word in Class C
Total = NA + NB + NC

They remain the terms that meet the following criteria:

(NA / Total) * 100%> X% or (NB / Total) * 100%> Y% or (CN / Total) * 100%> Z%

Is it possible?

Sure,

tokenize, generalte attributes and filter example should do that.

Classes are defined by the value of "label1" which are respectively -1, 0, 1. Suppose I want to remain the only terms which meet the following criteria:

([occurrence of words with label1] = -1) / total)> 0.7
([occurrence of words with label1] = -0) / total)> 0.7
([occurrence of words with label1] = 1) / total)> 0.7

Total =[ Occurrence in label1= -1] + [ Occurrence in label1= 0] +[ Occurrence in label1= 1]

What should I write on the fields inside "Generate Attribuite" and "Filter Examples"?

I cannot sendo the image to show you better. But there are fields to be filled inside "Generate Attribuite" and "Filter Examples".
