The design of a multi-domain Mandarin Chinese spoken dialogue system

چکیده
In some dialogue systems, the design of dialogue strategy is bound tightly to the domain by straightforwardly hard-coding the response actions into the system. Such a paradigm is quite easy to build up a prototype system, but makes it difficult to port the system across different domains. This paper presents a domain-transparent design of dialogue management to increase system portability. The basic idea of this framework is to extract the domain-dependent factors to form an external domain knowledge database, leaving the dialogue management component independent of the tasks. Based on the proposed framework, porting to another domain needs only to replace the domain knowledge database without changing the dialogue management module. This paper also proposed a task description table interface enabling system developers to design the dialogue strategy flexibly. With this approach, the effort of porting a spoken dialogue system across different domains can be relieved.

The Design of a Multi-domain Chinese Dialogue System
For a multi-domain spoken dialogue system, there are two major difficulties in building its dialogue management. One is to interpret users' interested domain correctly and switch between domains smoothly. The other is the high cost of merging the dialogue management of different application domains. To solve these problems, an implicit domain identification and switching mechanism for dialogue ...

In this paper, we propose a domain-transparent design of dialogue management in a mixed initiative Chinese spoken dialogue system engine. This design pushes the domaindependent parts of the dialogue management to the external task configure file, leaving the dialogue manager independent of the domain. The task configure file consists of a set of states each of which is associated with a task ac...

This paper presents an approach which integrates layer concept information into the trigram language model in order to improve the understanding accuracy for spoken dialogue systems and to improve the portability of the language modeling materials among different narrow-domain applications. With this approach, both the recognition accuracy and out-of-grammar problem can be largely improved, and...
