Abstract:In view of the lack of guidance and unscientific decision-making in the course selection process of officers and soldiers in the current military vocational education, based on the online course recommendation model of knowledge mapping and neural network, this paper proposes an analysis of the working principle of knowledge mapping technology and recommendation system based on collaborative filtering, uses neural network and big data technology to design, and carries out experimental design and result analysis. The results show that the model can take into account the learners' interests and the factors related to themselves, which provides a reference for solving the above problems.
