@Ayush Kumar I am assuming that this is a form that is manually filled out and you are using Azure document intelligence to extract the text? If Yes, Document intelligence can be trained to extract the text but to summarize the content you will have to pass the extracted text to Azure OpenAI endpoint as I don't think there is a direct integration of such feature with document intelligence APIs currently.
For the other scenario, to check if any field is not filled, I think the current Document intelligence model can be trained to recognize any blank content for any fields that it is trained to extract. The Analyze API response in this case will not have these fields in the response. I hope this helps!!
