基于G-KRA模型框架的工作流建模

Formalizing the Workflow Modeling Process Based on G-KRA Model Framework

基于广义知识重构与抽象(G-KRA)模型框架给出了工作流建模的一般过程,根据功能知识引入了功能感知的概念,自动构造工作流抽象对象库WfOa.构造基本行为感知和WfOa中的基于功能的工作流抽象对象之间的映射关系,实现基本行为感知与相应关系的替换操作.通过这些映射关系,生成了基于功能的工作流抽象模型以简化基本工作流模型的表示.

Knowledge Reformulation and Abstraction（KRA） model has been introduced to formalize the workflow Abstraction modeling process which is an iterative learning process of ＂Perception-Abstraction＂.Compared to KRA model,the general KRA（G-KRA） model is more general and flexible to represent the world which can represent the world from different Abstraction granularity.We provided the workflow modeling process on the basis of the G-KRA model.Particularly,we introduced the concept of function perception according to functional knowledge to automatically construct the workflow Abstraction objects database WfOa.The mapping relation between the primary activity perception and the function-based workflow Abstraction object of WfOa was constructed to realize the replacement of the primary activity perceptions with corresponding mappings.With the aid of these mapping relations,we generated the function-based workflow Abstraction model to simplify the representation of the primary workflow model.
