Design And Implementation Of News Briefing Editing Sysyem

In recent years,with the rapid development of technology,news and information have become increasingly diverse and complex.In governments,enterprises,and institutions,staff often provide decision-makers with auxiliary decision-making references by collecting and analyzing data and writing briefings.In the process of writing a briefing,there are many problems,and it is important to quickly and accurately classify the information content.The writing of the briefing also requires corresponding systems to help achieve it.This article introduces the background and related technologies of the project,analyzes the requirements of the system,and divides the system roles accordingly;Functional requirements include hotspot information,information retrieval,briefing management,and other requirements;Non functional requirements include system performance,reliability,safety,maintainability,etc.Secondly,the software hierarchical architecture of the system was designed accordingly,and the system functional modules were specifically divided according to actual requirements.The work of designing database E-R diagrams and tables was completed.Afterwards,research was conducted on the model for news text classification,suitable classification models were trained,commonly used news information data sources were summarized,and corresponding crawler techniques were used to crawl news data.Combined with classification models,data processing and classification were carried out;Afterwards,the development of a news briefing editing system was carried out.In the implementation of the system,this article follows the principle of separating the front and back ends for development.The backend mainly uses the SpringBoot framework for development.By using Spring Security and Jwt to ensure system security and permission authentication,Maven is used for project management in the backend,Mybatis is used to simplify persistence layer development,Vue technology is used for front-end page development,and crawlers are designed to collect data,For the collection and management of system data,MySQL and Elasticsearch technologies were used for data processing in the database,and Redis was introduced to manage timeliness data such as verification codes.The detailed design of module functions was completed by drawing the system’s sequence diagram and class diagram.At present,the news briefing editing system has been designed and evaluated,which meets the system requirements and can meet user needs,bringing convenience to user briefing editing work.
