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.

拓宽基于本体的个人助理的对话工作流建模瓶颈

我们提出了一种基于所谓的对话工作流图的虚拟个人助理 (VPA) 对话规范的新方法，与当前基于本体的方法相比具有几个已证明的优势。由于用户友好的建模框架，我们新的对话规范语言 (DSL) 使客户能够更轻松地参与 VPA 建模过程。由此产生的模型也明显更加紧凑。VPA 的开发速度要快得多。DSL 是我们基于本体的对话管理 (DM) 框架 OntoVPA 之上的新建模层。我们解释了新语言背后的基本原理和好处，并通过最近两个 OntoVPA 项目的具体降低的工作量 (LOE) 数字来支持我们的主张。
