With the rapid development of science and technology, knowledge update is accelerating, which puts forward higher requirements for teachers and students in Colleges and universities, and needs to grasp the latest development trends of curriculum knowledge related fields faster, more comprehensive and more accurate. Many schools have digitized their educational resources. However, the traditional sharing of educational resources lacks a unified knowledge representation structure, which makes the sharing and reuse of learning resources unsatisfactory. Curriculum is the core of school knowledge teaching. It evaluates the curriculum system and discipline system in order to achieve certain teaching objectives. Curriculum knowledge includes explicit knowledge and tacit knowledge. Knowledge map is a kind of model which can describe knowledge in semantic and knowledge level. Its purpose is to acquire, organize and present knowledge in a general and intuitive way, to search and match knowledge quickly, so as to improve the utilization of knowledge by learners and knowledge workers. Curriculum knowledge has obvious ontology characteristics, and there are many inconveniences and shortcomings in the presentation of traditional knowledge map. Using ontology technology to construct curriculum knowledge map can not only reflect the relationship between knowledge modules, but also realize the mining and representation of more knowledge relations and types such as tacit knowledge to a certain extent.
