To extract the main structural features, we first use the CRF algorithm to annotate different knowledge feature vectors based on cognitive mapping in this paper. To mine the correlation between the main structures and fuse them, the G-DINA technique is employed to set the threshold value. The response function is utilized to diagnose the cognitive parameters of students and accurately quantify their cognitive state. According to the results, the educational platform has an average coverage rate of 78%. The average cognitive index scores of the students were 75, and 92% were content with the teaching effectiveness of the platform. The intelligent Civic Education Platform constructed based on cognitive mapping integrates Confucianism and culture to achieve two-way development.
