How to convert ratings (1 to 10) to 3 classes (negative, neutral, positive)

I would like to convert ratings (1 to 10) to three disjoint classes representing the polarity of sentiment review (negative, neutral, positive). Is there any function in Rapidminor allows me to do so?

    Hi @Amika

    You can use the Generate Attributes operator nd implement an anidated conditional with your rating Attribute (colum), something like this. 
    if(yourratingattribute<=3,"Negative", if((yourratingattribute>3&&yourratingattribute<=7),"Neutral", "Positive"))

    Best.

    You can also use the Map operator to do this if the original attribute is nominal and not numerical data type.
