using OCR in email channel
We have an email channel configured which is using a predictive model for topic detection. We also have configured a number of models for entity detection. Now we have enable the option to also analyse the email attachments (from the email channel) for detecting the topics and/or entities.
My question is how to use OCR in a cloud environment (pega cloud) to detect the topic in PDF and image attachments. I was not able to find a page explaining this functionality. Is there a document available with some guidance how to implement this functionality?
