Research On The Construction And Application Of Knowledge Graph Of《 Mobile E-commerce 》Course In Secondary Vocational Schools

Secondary vocational education is an important part of our country’s vocational education,laying a solid foundation for the cultivation of high-quality skilled talents in our country.The mobile e-commerce industry is an important industry that promotes social and economic development,and the 《mobile e-commerce》 course,as an important course in secondary vocational e-commerce education,has been highly valued by secondary vocational schools.In the context of "Internet +",the Ministry of Education continues to promote "education informatization",requiring the promotion of an organic combination of information technology and vocational education.Knowledge graph is a technology that focuses on various semantic relationships between knowledge and knowledge,and stores,displays,and mines their mutual relationships with visual techniques.The knowledge graph can effectively display the relationship between the knowledge of the entire course,help students organize knowledge,and improve learning efficiency.Based on the fact that most students have difficulty constructing their own subject knowledge structure after completing the 《mobile e-commerce》 course,and the isolation of knowledge points has led to the problem of unclear thinking in solving comprehensive problems.This article uses the knowledge graph technology to construct the secondary vocational 《mobile e-commerce》curriculum knowledge graph,which is used to reveal the secondary vocational 《 mobile e-commerce》 curriculum knowledge system,standardize the knowledge structure method,and build the relationship between the knowledge points.First,use the literature research method to investigate and analyze the content requirements of the mobile e-commerce courses.The content of the courses covers the job groups for enterprise employment,the skill requirements for the training of rural revitalization talents,the ability requirements for the connection between middle and high vocational schools,and the knowledge requirements for the research direction.Then,using the obtained course data as a reference basis,according to the internal relevance of the knowledge points in the knowledge system,design and construct the knowledge graph of the secondary vocational 《mobile e-commerce》 course,and process the data and store it in the neo4 j database.Design the overall structure of the knowledge graph system,use the B/S architecture to complete the interaction between the web server and the database,and realize the visualization of the knowledge graph.Finally,apply the constructed 《 mobile e-commerce 》 course knowledge map of secondary vocational education to classroom teaching,conduct a questionnaire survey of the students who have used it,analyze learners’ attitudes towards the use of knowledge map and collect improvements to the course knowledge map opinion.The research results show that the learning method based on the knowledge map of the《mobile e-commerce》 course in secondary vocational schools can increase students’ interest and confidence in mobile e-commerce courses,enhance their learning initiative,and help them get a good emotional experience.It also enhances the students’ ability to grasp the overall structure of the curriculum and knowledge points,which is conducive to promoting the formation of curriculum knowledge structure.
