how find Cluster center in text

m_keshavarz_com

Hello to all
Sorry
I am a beginner at RapidMiner
I need to work with RapidMiner for the university project
I have a thousand reviews
I want to cluster with more important words by weighting
I did this process
But
Only the words weighed clustered
I want to make sentences based on these words clustered
But there is an error
Can anyone tell me what to do?
And
I want to find the center of the cluster
What is the word cluster center or sentence?
Does anyone know how?

Thanks a lot
Please help me

@m_keshavarz_com your problem is that you're passing non-numerical data into the 'Determine Influence Factors' subprocess. Either Dummy-code them or remove them.

Hello
Dear Professor
Mr. @Thomas_Ott
Sorry i did not understand
what must I do?
Can you guide me more accurately?
Thank you
I really need your help.
With respect

@m_keshavarz_com you might to put a Nominal to Numerical operator before the data gets to the Influence Factors subprocess. This way all the data is numerical and the subprocess should be able to run.

Hello
Thank you
You are right
I did
But clustering only the words that are more importantly extracted. Not the sentences containing the words
I want clustered sentences based on these important words.
But do not know how
Thanks a lot
