hello,

mikoo · November 2023

im currently doing sentiment analysis using rapidminer all the process have run successfully, but my questions is based on the result i want to produce count of sentiment for certain words based on my data. let say i want to know how many the word "location" appear and how much is the positive and negative sentiment for it based on another factor let say "university". what i mean is that i have an attribute university and i want to know for each university how many is the count of sentiment for the word location. is this possible to do? because when I use visualisation, if i want to know the count for location and let say also the word cost it will give me the same total for both word and i think it doesnt seem valid. can anyone help me how can i figure out this or how to properly plot the visualisation to get the right total count.

Hi mikoo,

yes this should be possible. Could you please share the process XML with us to look closer into the process?

Have you tried to use the Aggregate Operator and and group by the university?

Thank you & best regards

i have tried using the Aggregate Operator but it doesnt output the result that i want. if you can take a look of the file i attached here, what i want is for each university in the data i want to know how many positive & negative & neutral value for certain word, like facility, for university Malaya , is this possible to happen?

hello, sorry for asking but is it possible for me to have the rmp file?

ClaudioKeck · December 2023

Sure, here you go:

The only changes I made were adding a Declare Missing Values Operator for 0, and than aggregate per University and Sentiment using aggregation function " count (ignore missing)"

mikoo · December 2023

alright thank you so much for your help.
