Towards a new implementation approach for rapid development of text-based dialog systems

Dialogue Systems are now more and more used in real life. However, such systems are usually difficult for lay people to create. Some less complicated methods have been proposed, although with less powerful understanding capability. After introducing and comparing the approaches mentioned above, the grammar parsing part, named GrammarTool, of a natural language text interface Spoken Dialogue System (SDS) toolkit, named SDS Lite, is described in detail. Our system deals with Chinese dialogue and makes it very easy for lay people to learn and create their own SDS. 1
