Abstract
Examples of the present disclosure describe systems and methods relating to conversation state management using frame tracking. In an example, a frame may represent one or more constraints (e.g., parameters, variables, or other information) received from or generated as a result of interactions with a user. Consequently, each frame may represent one or more states of an ongoing conversation. When the user provides new or different information, a new frame may be created to represent the now-current state of the conversation. The previous frame may be retained for later access by what is referred to herein as a “dialog agent,” which is the portion of the system that can search and use previous state-related information. When an utterance is received, a frame to which the utterance relates may be identified. Thus, the dialog agent may track multiple states simultaneously, thereby enabling conversation features that were not previously possible.
