Online Learning of Social Science Courses Based on Personalized Recommendation Algorithm
The recommendation algorithm has been used to find the course of interest in the vast amount of online learning resources. This paper analyzed the recommendation algorithm briefly and designed an improved user-based collaborative filtering recommendation algorithm (UCFRA) recommendation algorithm based on UCFRA by improving its matrix filling based on the item attribute. It was found that when the number of K nearest neighbors was 80, the precision rate of the improved UCFRA was 0.5387 for the MovieLens 100K dataset, which was 5.13% higher than that of the UCFRA. For the social science course dataset, the highest precision rate of the improved UCFRA was 0.5429, and the highest coverage rate was 0.4559, both of which
were better than the UCFRA. The experimental results verified that the reliability of the designed recommendation algorithm for social science course recommendation. The algorithm can be further applied.
