We present a new approach to dialogue specification for Virtual Personal Assistants (VPAs) based on so-called dialogue workflow graphs, with several demonstrated advantages over current ontology-based methods. Our new dialogue specification language (DSL) enables customers to more easily participate in the VPA modeling process due to a user-friendly modeling framework. Resulting models are also significantly more compact. VPAs can be developed much more rapidly. The DSL is a new modeling layer on top of our ontology-based Dialogue Management (DM) framework OntoVPA. We explain the rationale and benefits behind the new language and support our claims with concrete reduced Level-of-Effort (LOE) numbers from two recent OntoVPA projects.

翻译：我们以所谓的对话工作流程图为基础,为虚拟个人助理(VPAs)提出了新的对话规格,与目前基于本体学的方法相比,有一些明显的优势。我们新的对话规格语言(DSL)使客户能够更容易地参与VPA建模过程,因为这是一个方便用户的建模框架。由此产生的模型也更加紧凑。VPAs可以更快地发展。DSL是我们基于本体对话管理框架OntoVPA的一个新的建模层。我们解释了新语言背后的理由和好处,并以最近两个OntoVPA项目中具体减少的Effort(LOE)数字来支持我们的要求。
