【摘要】 将系统工程V模型开发设计思想应用于知识系统的需求分解,并将知识系统的领域本体分为概念本体和任务本体两大部分.其中概念本体描述知识系统的静态知识,任务本体描述知识系统的动态知识.以一个简化农业种植结构配置知识系统为例,建立了系统的应用本体求解模型.这种基于需求分解的领域本体建模方法具有面向问题和应用、实效性强、执行效率高等优点.更多还原

【Abstract】 The thought of V model in system engineering is applied in decomposing requirements of knowledge system. The domain ontology is divided into conception ontology and task ontology. The conception ontology is used to describe static knowledge of system, and the task ontology is used to describe dynamic knowledge of system. The model are tested and verified by examples of agriculture crop analysis. The proposed ontology models have advantages of problemoriented, parallel implementation and high efficiency etc.更多还原
