Study And Implementation Of A Wechat Service System Base On Personalized Recommendation Of Mathematical Olympiad

Recently,the government announced that the Olympic Games will be closed to reduce students' burden.However,this move does not really reduce the burden on students who are interested in learning the Mathematical Olympiad.In the era of rapid development of the mobile Internet,the existing mode of education also need to reform to meet the people more and more fast way of life.The key issues in the education industry to be solved are low learning efficiency.Therefore,it's important to arrange the material of learning according to student's personality,which could completely reduce student's burden by improving the learning efficiency.This paper designed a personalized recommendation algorithm towards exercise to make individual recommendation for each student,depending on the degree of mastery of the study content.Thus,the students could make up for their shortage during their study.Besides,this paper designed a Wechat service system based on personalized recommendation of Mathematical Olympiad,which is aimed to facilitate students' learning and assist teachers' work of supporting and managing students.This paper makes three main contributions: 1)This paper focus on using a method that contains web segmentation,construction of the corpus and exactly extraction of the titles;2)This paper proposed a hierarchical label technology based on link cluster to satisfy the real demand of the exercise's label;3)This paper proposed a model of relationship between label and exercise,which is constructed by hierarchical label technology.When a student demand for the content to study,the study content can be sorted and filtered by this model.4)This paper designed a Wechat service system based on personalized recommendation of Mathematical Olympiad,according to the demand of students and teachers during studying the Mathematical Olympiad.This system is aimed to fulfil the demand of student and teacher during studying and provide an online education computer aided instruction.The experiments' result proved that the proposed method could obtain the degree of the mastery exactly and cover the shortage with recommendation of the exercise.In addition,the test results of the system show that the system is operational and could support the online Mathematical Olympiad study for the students and teachers.
