The present teaching relates to auto generated summaries of communications and enabled services. Summaries are automatically generated based on machine trained models for communications between customers and service agents. A summary modification history is created for each of the summaries including the machine generated summary and some updated versions of the summary. When a service request is received from a customer, a summary modification history of a prior communication associated with the customer is retrieved for responding to the request. Using the summary modification histories, feedback data is generated, which is then used for updating the models.
