“…Users who have common interests in the same course may give different ratings to the course. At the same time, referring to the famous Ebbinghaus forgetting curve, a nonlinear logistic function is designed for the algorithm to explore the user's rating forgetting rule more closely, so as to give each normalized rating a different time forgetting weight [14][15][16]. Considering the influence of the recommendation and the authenticity of the neighbor set, this paper sets an effective weight factor when calculating the user similarity, which helps to improve the accuracy of the recommendation result [17].…”
