An Extensible Dialogue Script for a Robot Based on Unification of State-Transition Models

الملخص EN

We propose extension-by-unification method to improve reusability of the dialogue components in the development of communication function of the robot.

Compared to previous extension-by-connection method used in behavior-based communication robot developments, the extension-by-unification method has the ability to decompose the script into components.

The decomposed components can be recomposed to build a new application easily.

In this paper, first we, explain a reformulation we have applied to the conventional state-transition model.

Second, we explain a set of algorithms to decompose, recompose, and detect the conflict of each component.

Third, we explain a dialogue engine and a script management server we have developed.

The script management server has a function to propose reusable components to the developer in real time by implementing the conflict detection algorithm.

The dialogue engine SEAT (Speech Event-Action Translator) has flexible adapter mechanism to enable quick integration to robotic systems.

We have confirmed that by the application of three robots, development efficiency has improved by 30%.
