The Design And Implementation Of The College Entrance Examination Volunteer Recommendation Subsystem Of "Road To Higher Education Platform"

The "Road to Higher Education Platform" is a recommendation platform for high school students and parents developed and operated by Henan 863 Software Incubator Co.,Ltd.The platform includes five parts: college headlines,college information query,Xiaolu travel,customer center,and college entrance examination voluntary recommendation.The headlines provide various policies and news related to education.Inquiry of college information provides users with timely and comprehensive information of domestic colleges and universities.Xiaolu Traveling provides users with relevant information and policies for studying abroad.The user center manages usersThis paper designs and implements the core part of the platform,college entrance examination voluntary recommendation subsystem.The subsystem collects the admission status of various colleges and majors in previous years,analysis user scores of entrance examinaition,extracts the typical characteristics of students through user tags and user portraits,and then uses the gray prediction algorithm to calculate the college admission probability,weighted and compared to sort by AHP method,and finally selects 9 schools that are suitable for users.Main tasks as follows:(1)The requirements analysis stage collects and confirms requirements through on-site interviews,expert meetings,and references to related platforms in the same industry.Use case diagrams to construct the functional model of the system,use class diagrams to establish the domain model of the system,and use business flowchart diagrams to describe the behavior model of the system.(2)The overall design stage establishes the system's organizational structure and topology,establishes the correspondence between system requirements and functions,designes the database's logical structure and entity tables,analyzes and designes the college entrance examination voluntary recommendation matching algorithm model,generates user portrait based on the college entrance examination scores,so that the GM(1,1)model,the standard normal distribution and AHP method are applied to select 9 suitable schools for a user.(3)The detailed design stage describes the business process of the system by drawing class diagrams,sequence diagrams,and flow charts.The object-oriented design method is used to determine the system's sub-module composition and algorithm logic.It is implemented using MVP framework and Java language.At present,a large number of students and parents have registered and used the "Road to Education Platform" that integrates the voluntary recommendation subsystem of the college entrance examination.The results of their voluntary recommendation have a high reference value and have been consistently praised.
