复杂产品协同设计流程的多视图自然语言文本生成

Multi-view natural language text generation method for complex product design process

为了业务人员更好地理解复杂产品设计过程的业务流程建模标注(BPMN)模型,以便与系统分析人员进行有效沟通,提出一种基于BPMN模型的复杂产品设计过程多视图自然语言文本生成方法。该方法能够根据业务人员的不同需求对流程模型进行结构投影,进而使用句法分析和语义角色标注解析BPMN流程模型的文本信息,并使用流程结构树(RPST)算法解析BPMN流程模型的结构,从而将流程模型划分成具有层次的子流程片断得到流程结构树。解析的文本信息与不同视图下的流程结构树合并,形成带注释的多视图流程结构树,然后使用语法树由带注释的流程结构树自动生成自然语言文本,最终生成多视图下的自然语言文本。所提方法已在系统中实现,并通过测试集进行实验验证了所提方法的有效性。

To facilitate the business staff to better understand Business Process Model and Notation（BPMN） model of complex product design process and to communicate effectively with system analysts, a multi-view natural language text generation method of complex product design process was presented based on BPMN model, which could create the projection of process model according to the different requirements of business staff. The text information of BPMN process model could be annotated by using syntactic and semantic roles, and the structure of BPMN process model could be analyzed by using Refined Process Structure Tree （RPST） algorithm. The process model was divided into hierarchical sub-process fragments to get the process structure tree. The parsed text information merged with the process tree to form the annotated multi-view process structure tree, and then the syntax tree was used to automatically generate the natural language text from the annotated process structure tree. The multi-view natural language text was generated. The method had been implemented in the system, and the test set had been used to verify the effectiveness of the proposed method.
