Abstract: Protégé is used as a knowledge modeling tool to build the auto manufacture domain ontology. On the platform of Jena, semantic search and rule reasoning based on ontology are used to create the auto components purchase order. Ontology is a specification of a sharing conceptualisation of a knowledge domain.It has powerful semantic expression ability to express sharing conceptualisation.More over,with certain reasoners ontology supports automatic reasoning mechanism.Thus using ontology, automatic knowledge integration among corporations in the supply chain can be realized.

Key words: Automatic Knowledge Integration, Ontology, Semantic Search, Rule Reasoning, ERP

摘要： 本文使用Protégé作为知识建模工具开发汽车制造领域本体，以Jena为开发平台运用基于本体的语义检索技术和规则推理实现订单的自动生成，开发了一套基于本体的汽车零部件采购订单自动生成系统。由于本体是共享概念模型明确的、形式化的规范描述，将本体应用到汽车制造行业的ERP系统中，可以利用本体强大的语义关系表达能力和本体描述知识的共享性，以及建立在其上的自动推理机制实现供应链企业间异构知识的自动集成。
