Research And Implementation Of Microblog Content Filtering Technology

With the rapid development of network technology, more and more people start using microblog. Microblog is an media platform of information dissemination. On this platform, everyone can timely, quickly and easily publish their own information or others’information. But everyday on this platform, millions of microblog information would be produced, and some of which inevitably include illegal, unhealthy and discordant contents. Therefore, One system is of great significance which can filter the microblog’s content and purify the Internet environment to making sure provide users a green, healthy, positive atmosphere on the Internet.The design and implementation of one microblog system with content filtering by Java based on SSH framework and MySQL in this dissertation. Firstly the system is set up as a microblog platform, and on this foundation, to implement the microblog filtering. The overall system is divided into two parts:The foreground system mainly contains the functions for users, which are the basic functions of microblog, microblog content filtering, user information settings, editing followers and other functional modules; The background system is the system which has administrator’s main features, including the administrator management, user management, resource management, bulletin management and other functions. In all these function modules, it focuses on the design and implementation of microblog content filtering module that combines the search methods of Lucene and the word processing technologies of natural language. There are two main methods:shielding and filtering in microblog content filtering processing.According to the principles of the waterfall model of software engineering, this dissertation describes the system business requirements, the function requirements, the non-function requirements, the system architecture design, the function design and the database design. For the key function modules, it shows the results with the interface and the code based on the software development environment. At last the system functionality and performance tests are carried and the results shows that the system runs well.
