Design And Implementation Of Recommendation System For Basic Education Questions Database

Recommendation system are widely used in today's software development and even Internet products and applications.They include well-known and frequently used products searches,popular keywords,topic recommendations,various product recommendations in e-commerce,and ads in WeChat moments.In the elementary education and middle education stage,the question database system is an important part of the autonomous learning process.Under the current question bank system,users can only manually set and combine the test papers for the users to use based on subjective selection or administrator operate.The subjectivity is very strong and the problem in the self-learning process could not be found effectively.If the recommendation system can be combined with the question database system and applied in the subject selection process of independent learning,it can objectively reflect the user's defects in the testing process,and make inquiries on these issues.The end result can reduce the subjective bias of self-selected topics and improve the effectiveness of users after using the system to enhance learning.This article starts from the topic background and the current status of the recommendation system,conducting in-depth research on the relevant basic theories of the recommendation system,in order to find the recommendation algorithm that is suitable for the basic education question database system.This article uses the combination recommendation algorithm to combine the content-based recommendation and collaborative filtering recommendation.Then the requirement analysis of the recommendation system for basic education question question is conducted,setting the learning model with knowledge point as the core is determined with the hierarchical structure features of the knowledge point and the required function modules clarified.The demand module design for the system includes the design of the whole Detailed design of system architecture,database architecture,functional and non-functional modules,finally achieving the prototype of the recommended system.The system adopts a REST architecture and builds a software system for Web management and providing interface services based on technologies such as PHP,Redis,and jQuery.
