Design And Implementation Of K12 Educational Resource Management System Based On Android Technology

In the Thirteenth Five-Year Plan of Education Informatization,the Ministry of Education further clarifies the goal of "unremittingly promoting the construction of education informatization,especially basic education in primary and secondary schools".In this context,K12 educational resources information platform,to a great extent,enriches the school classroom at the same time,can help students continue to expand the edge of students' knowledge.Therefore,the development of k12 education resource management system based on Android technology has a certain practical significance.Firstly,this paper briefly describes the background and significance of K12 educational resource management system,compares the development status of domestic and foreign education-related systems,and clarifies the research direction of the system.At the same time,the related technologies such as automatic classification algorithm and information acquisition are introduced,and the research and application of related theory technology are also introduced.Then,the overall design and implementation scheme of k12 education resource management system based on Android is elaborated.Through the needs analysis,it is clear that the functions of the system need include user registration and login,system resource management,training and learning module,resource classification module,education space management and communication forum module.This paper introduces the overall design scheme of the system,focusing on the detailed design of K12 educational resource management system,including the functional design,architecture design,and analysis of the corresponding development tools and operating environment of the system.In addition,in the part of system implementation,the flow chart and operation interface show the process and results of each functional module.Based on the automatic classification algorithm and information acquisition technology,the text resources are automatically classified.Classifying educational resources by automatic classification algorithm can greatly improve work efficiency,quickly locate the location of target resources,and simplify the process of resource search.Finally,through testing the performance and function of the system,the test results show that the development of the system achieves expectations.This system extracts information based on HTML structure,uses web pages to filter duplicate pages,processes text and document segmentation with forward maximum matching algorithm,uses TFIDF method to select features to reduce eigenvector calculation,establishes classification judgment model of educational resources,calculates the similarity of vector space model between text and document,and chooses locally sensitive Hash KNN algorithm to process text and document segmentation.Documents are classified in order to realize the automatic classification of educational resources,so as to improve the efficiency of classification and provide more convenient educational resources services for users.
