ABSTRACT

The Internet age is an era of information explosion. People can receive a wide range of information from various platforms every day. These information may be of interest to users, and may be disgusting to users. The most efficient way to get the content you need is the general problem. This topic studies the information explosion brought about by the development of technology and demonstrates the necessity of effectively screening information. The main content of this paper is to design and implement an information website to provide information filtering function for users in the Internet age.

This article describes the feasibility of the system and user requirements in detail. The designed information website is positioned as an information platform for users to collect and filter information. It uses collaborative algorithms to capture the latest information based on user preferences, and realizes information display and information. Push, information search and other functions.

This paper takes the basic idea of ​​software engineering as the guiding ideology, divides the requirements research, analysis and project design work of the project into strict stages. At the same time, it uses the object-oriented analysis and design idea to model the use case of the system. The implementation of the system mainly uses Java as the development language, and uses the MySQL database to perform unified management of system information.

Keywords: information explosion; collaborative algorithm; user preference; information screening
