摘 要: 结合骨架法和七步法这两种常见本体构建方法的优点,提出适用于初中数学知识本体的构建方法,借助Protégé工具实现初中数学知识本体的构建,利用Jena 开源包对本体进行关系推理,并从体系结构和实例两个维度建立评估指标,验证构建的本体是否层次分明、关系丰富,清晰地描述初中数学体系结构中各知识点的属性和知识点之间的逻辑关系。本研究对个性化教学系统的建设有实用价值,对初中数学知识的有效管理有一定的理论意义。
关 键 词: 计算机应用;本体;知识体系;关系推理;本体评估

Abstract: A new suitable method for junior high school mathematics knowledge ontology is put forward, which combines the advantages of the skeleton and seven steps methods. The knowledge ontology building is realized with the help of Protégé. The Jena open source package is also used for relationship inference. The evaluation indexes are established from two dimensions: the architecture and the instance. It is concluded that the ontology is well arranged and has rich relationship. It clearly describes the attributes of each knowledge point and the logical relation between the knowledge points. It has practical value for the construction of personalized teaching system, and certain theoretical significance to the effective management of junior high school mathematics knowledge.
Key words: computer applications; ontology; knowledge architecture; relationship inference; ontology evaluation
