An automatic question answering system serves to respond to questions pertaining to a user-selected domain of a plurality of domains. A plurality of documents pertaining to the domain are received and processed to identify candidate answers. Questions corresponding to the candidate answers are automatically generated. The candidate answers and the questions are used to train a machine comprehension (MC) model. A user interface allows the selection of one of the plurality of domains for querying by a user. When a user query pertaining to the selected domain is received, the user query is analyzed to identify a relevant context from the plurality of documents. An answer span to the user query identified by the MC model from the relevant context is used to frame a complete response to the user query.
