Hey,
I was wondering if anybody knows how the final scores in the extract sentiment operator are being calculated. How can I have a negative sentiment when all values in the matrix are positive?
Thanks for help!
Greetings
Lena

AFAIK, the Extract Sentiment operator calculates the sentiment based in what the WordNet provides, and it reflects whether the sentiment is neutral (down to zero), negative (near to -1) or positive (near to 1). The complexity of the calculation depends on what parts of speech are you including in your process.
Do you mind to include your process to make a more educated guess?
All the best,
Rodrigo.

attached is my process. Where can I find the new Extract Sentiment operator in my toolbox? I just updated RapidMiner and cannot find it.
Thanks
