Accurate Recommendation Algorithm of Preschool Education Network Resources Based on Improved Decision Tree

Aiming at the difficulty of users obtaining preschool education network resources, a precise recommendation algorithm of preschool education network resources based on improved decision tree is proposed. The categories of effective information of preschool education network resources are adjusted by improved decision tree, combined with the reconstruction of preschool education network resources, Extract the effective information of preschool education network resources, set the weight threshold of preschool education network resources similarity through the analysis of the similarity of different preschool education network resources in the data set, calculate the weight value, obtain the similarity between preschool education network resources in the data set, obtain the distribution of the similarity between preschool education network resources, and complete the calculation of the similarity value between preschool education network resources, Through user interest modeling, an accurate recommendation algorithm for preschool education network resources is designed. The experimental results show that the accurate recommendation algorithm of preschool education network resources based on improved decision tree has good effect and performance on preschool education network resources recommendation.
