Getting a Sentiment Score after Processing Documents operator?

tobow

Hello RapidMiner Community,

I'm trying to read pdf-documents and then perform a Sentiment Analysis using the Process Documents operator. However, I'm having trouble connecting the Process Document Operator to the Apply Model operator. I have tried using the Data to Documents operator, but to no success. Here is a screenshot of my process:

Does anyone know which operator to use or if there is a better way of retrieving the Sentiment Score? 

Thanks alot in advance

Hi,

the operator expects a list of documents as an input. Thats the output of Loop Collection. You can do the preprocessing in this loop collection.

Best,
