At present the ‘Remote Teaching Assistant system’ is lack of interaction, which can merely provide curricula, online courseware, and other functions. This paper tries to propose a frame of remote teaching assistant system based on ontology which can use ontology for the expansion of the traditional system, providing for the common functions, enhanced interaction with the students by allowing users to search frequently asked questions, and ontology reasoning, the results of inquiries made more in line with the peoples requirements. This paper attempts to study each kind of technology that utilized in building a ‘Remote Teaching Assistant’ system based on ontology and make Data Structure course as an example. Firstly several important definitions that related to ontology is described, including the concept and development of ontology, the function to construct it the construction language, tools, principle and application. Subsequently, the tools and principles of reasoning based on ontology are stated. Furthermore, how the new system is designed and realized is introduced in details and the result is showed. The OWL language is applied in this system
