They are also free to change topics or otherwise throw a curve ball at your application at any point in the interaction without warning. Users can shortcut directly to the functionality they want. The power of conversational applications lies in providing minimal constraints on what a user can say during an interaction. For simple conversational interactions, the set of dialogue states can be straightforward, as illustrated in the flow diagram below. Specify the Superset of Dialogue States ¶īefore you can begin to implement dialogue state handlers, you must first define the dialogue states your application requires. And because MindMeld is fully extensible, you can supplement MindMeld's built-in pattern matching capabilities with whatever custom logic you need. MindMeld provides advanced capabilities for dialogue state tracking, beginning with a flexible syntax for defining rules and patterns for mapping requests to dialogue states. For now, however, nearly all commercial applications rely heavily on rule-based and pattern-matching approaches to accomplish dialogue state tracking.įor most use cases, the procedures described in this section suffice to configure the dialogue manager, which you need not deal with directly. Applying large-scale machine learning techniques for dialogue state tracking is an active area of research today. The task of mapping incoming requests to appropriate dialogue states is called dialogue state tracking. The dialogue manager analyzes each incoming request and assigns it to a dialogue state handler which then executes the required logic and returns a response. A set of dialogue state handlers define the logic and response required for every dialogue state that a given application supports.Ī dialogue manager is at the core of every conversational application. For each dialogue state, a particular form of response is appropriate, and, particular logic may be invoked to determine certain parts of the content of the response. Conversational interactions consist of steps called dialogue states. Today's commercial voice and chat assistants guide users through a conversational interaction in order to find information or accomplish a task.
