Embodiment Construction

[0025] The present invention provides a method and system for task-oriented, multimodal dialog management to maximize the probability of successful task completion.

[0026] Figure 1 is a block diagram of an exemplary system implementing a method for dialog management in accordance with a preferred embodiment of the present invention. The computer-based system 102 is connected to at least one modality 104 to interact with a user. The computer-based system 102 includes a modality resource monitor (MRM) 106 , a task modeler 108 , a confidence measure extractor (CME) 110 and a dialog manager 112 . MRM 106 monitors each modality 104 and provides information to CME 110 . Task modeler 108 stores a repository of task models associated with each task, and provides the task models to session manager 112 and CME 110 . CME 110 provides confidence metrics for task models at various levels of abstraction to dialog manager 112 . The CME 110 may optionally have a post-evaluation module (P...

Abstract

A method and system (102) is provided for a multi-modal task-oriented dialog management implemented on a computer-based system. The system (102) maximizes the probability of successful task completion after a task is requested (302). Every task is associated with a task model comprising recipes, acts, parameters and modalities. Confidence measures are calculated at various levels for each task. The confidence measures represent the probability of success of the action depending on the user preferences. The most suitable recipe, act, parameter and modality are selected at runtime using the provided confidence measures (304) to maximize the probability of task completion. After each act, confidence measures are modified (312) depending on the user response, and the next suitable act is accordingly selected. Optionally, a post evaluation module (PEM) is provided for monitoring the user response and modifying the formulation for the confidence measures calculation.

Description

technical field [0001] The present invention relates to dialog management systems. More specifically, the present invention provides a method and system for facilitating task completion using a task-oriented, multi-modal dialog management system. Background technique [0002] Recent decades have witnessed an increase in the complexity of software applications. It happened mainly to provide more automation and better functionality to users. Improvements in processor speed, hardware architecture, and network connectivity have also facilitated the process. As the complexity of the application increases, so does the interface between the user and the application. [0003] The user interface acts as an interface between the user and the respective software applications. For input / output to the user, user interfaces typically use multimodality. A multimodal user interface system is a user interface system that uses various communication channels, such as a keyboard and a spee...
