Abstract
Interactive services with multiple interfaces are realized by employing a modular approach to their implementation. Such an approach facilitates supporting natural language understanding interaction with users through use of interfaces that at least allow the user to provide information beyond what is currently being requested by the service, and/or different ordering of inputs, and/or incomplete information, and/or correction of information, and/or the return of control to prior points in the service. This is realized, in an embodiment of the invention, by employing an interactive service logic that uses “reactive constraint graphs”, i.e., a form of event-driven graph in which nodes contain constraints on events, in conjunction with a service monitor. The service monitor manages the communication between the service logic and the multiple user interfaces. As such it provides a communication mechanism in the form of a so-called “look ahead” in which the user can input information beyond what is currently required by the interactive service. Specifically, in each round of user interaction, reactive constraint graphs report to the service monitor the set of ev…
