Abstract
A system for processing user utterances and/or text based queries that tracks context data of a current dialog between the system and the user, can determine values for slots by determining if the value was mentioned in a previous turn of the dialog. The system may employ a question-answer model and construct a question including the domain name, slot name, and potential slot values. The system may process the previous turns of the dialog and the constructed question to determine the slot value. The system may track a dialog that relates to multiple domains and may determine the slot value based on a slot value that is mentioned in relation to another domain.
