The learning resources of primary English of China are currently very abundant.It leads to difficulty for learners to find appropriate learning resources which is significantly increased as well.Adaptive learning systems can match the recommended learning resources and evaluation questions based on learning characteristics and learning paths of different learners, thus, the data organization structure of adaptive learning system plays a key role.Relational databases hardly reflect the intrinsic correlation between knowledge of specific subject.Therefore, this study proposed a constructional method by using ontology to connect relatively knowledge, and developed adaptive learning system for the fourth-grade students of China to learn English from multiple perspectives.The method can be used as a reference for other adaptive systems.%目前中国的小学英语学习资源非常丰富,学习者想要找到适合自身的学习资源的难度也明显提升.自适应学习系统可以依据不同的学习者特征和学习路径,推送出符合学习者的学习资源和测试题目,因此自适应学习系统的数据组织结构是非常重要的.而关系数据库无法体现出知识之间的内在关联,所以本研究提出使用本体技术将小学英语教材的相关知识有机关联的方法,为项目提供数据支持,以实现学习者的自适应学习,且希望对其他自适应系统的知识库构建起到借鉴作用.
