基于需求分解的知识系统建模方法

Study on Domain Ontology Model Based on Requirement Decomposition

通过对知识系统的需求分析及分解,将知识系统的知识划分为领域概念知识(概念本体)、系统知识(任务本体)、控制知识和解释知识四大部分,初步建立了各部分的实现框架和相应的策略,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知识系统建模方法具有面向问题和应用、实用性强等优点。

One knowledgebased system modeling method is proposed by decomposing requirements of knowledge system. The knowledge of intelligent system is divided into domain conception knowledge(conception ontology),system knowledge(task ontology),control knowledge and explanatory knowledge. The conception ontology is used to describe static knowledge of system, and the task ontology is used to describe dynamic knowledge of system. The proposed framework of model is tested and verified to be problemoriented and practical by an agriculture crop analysis example..
