Given the subjective and one-sided problems existing in the current evaluation system of e-commerce courses in secondary vocational schools, this paper puts forward the implementation path of “four in one.” Through the integration of big data technology, knowledge graph technology and the PGSD ability analysis model, the evaluation graph is constructed, aiming at achieving comprehensiveness, adaptability, professionalism, scientific and objectivity of the evaluation. The evaluation graph includes a three-tier structure of evaluation system, knowledge domain and skill dimension, and systematically distributes weights to realize the development of multi-dimensional evaluation and personalized learning path.
