针对网格工作流的描述方法提出了一个新的视角:运用知识表达技术提供一个网格工作流的语义模型和查询机制,并将面向对象的继承思想引入到网格工作流表达的语义框架中,该框架是可扩充、可配置的,用户可以对新的类别定义新的语义框架,并可基于该继承结构的语义框架,进行有层次的工作流的查询.
With the desire for knowledge retrieval and reuse, the need of a semantic grid workflow description framework emerged. This paper described a new angle of view to define how to accomplish this task. It is based on knowledge representation technology to provide a semantic workflow representation and query mode. Furthermore, the object-oriented inherit idea is imported to the frame which is extendable and configurable, and users can perform semantic query in the inherited structure.
