系统中心本体的工作流建模

摘要
知识重构与抽象模型作为一个表示改变的模型,既包含语义重构也包括了抽象.基于本体类以及本体类之间的映射关系扩展了抽象过程,同时引入了目标感知的概念,形式化地描述了分层工作流抽象建模过程.引入基于工作流片段的本体类,并且分别从基于对象的角度和基于流的角度给出它的分层表示,即工作流片段抽象以及工作流片段聚合.基于工作流片段的本体类给出了系统中心的知识学习、共享和重用的机制,节省了工作流再设计和再建模的成本.基于系统中心本体构造工作流的分层抽象模型,比基于对象中心本体构造的分层模型更加抽象,可以进一步简化推理.
Knowledge Reformulation and Abstraction model has been proposed to be a model of representation change that includes both syntactic reformulation and abstraction. The process is extended on the basis of the ontology classes and the mappings between them.The concept of goal perception is introduced to formalize the goal-based hierarchical process of workflow abstraction modeling.This paper furthermore introduces system-centered ontology to formalize the hierarchical workflow modeling process. We propose the concept of workflow fragment-based ontology class and provide its hierarchical abstraction process respectively from the objectbased perspective and the flow-based perspective,i.e.,workflow fragment abstraction and workflow fragment aggregation.Workflow fragment-based ontology class gives the mechanism of system-centered knowledge learning,sharing and reuse to save the cost of redesign and remodeling of workflow models.The hierarchical workflow abstraction model based on workflow fragments( from the perspective of the system-centered ontology) is constructed which is more abstract than the object-centered ontology and simplifies the reasoning.
