Design And Implementation Of Hot Public Opinion Analysis System Based On Multi Source Social Media

At present,the new generation of network information technology is constantly innovating and breaking through,and the Internet has become an important carrier of information dissemination in today's society.Social media,a new network interaction platform based on Internet technology,has been widely used in the world,which has a profound impact on social political life,network security,business activities and public events.The rapid development of social media platform has become the new focus of Internet intelligence collection field.For the public opinion events with great potential energy of conflict,we need to do a good job of analysis,statistics and processing.The hot public opinion analysis system based on multi-source social media is to analyze and display the hot events through different dimensions.This article first analyzes the business process,user roles,functional requirements and non-functional requirements of the system.User roles are divided into ordinary users and administrators.Functional requirements mainly include hotspot public opinion analysis requirements,configuration management requirements,and background management requirements.Non-functional requirements include performance,ease of use,and safety.Performance indicators are mainly based on the average retrieval response time of user information and the average response speed of the page.Secondly,this article designs and deploys the network architecture,and designs the software hierarchy based on the Spring Boot development framework.This article also divides the system into hotspot analysis module,configuration management module and background management module according to the boundaries of different functions and actual business needs.And complete the database E-R diagram and database table design,as well as the design of the system interface.This article uses the core technology Spring Boot framework,Solr technology,MySQL technology to design the view page,control class,model class,database table call method and interface call process of each module of the system,and complete the module function by drawing sequence diagrams and class diagrams Detailed design.Finally,this article selects the hardware equipment of the server by setting up the corresponding test environment,and designs test cases for the modules of the system.This paper compares whether the expected result and the actual result are the same,and completes the test of the system.The test results show that the system is complete and in line with the business content,and the performance indicators are within the required range.
