Design And Implementation Of Network Public Opinion Monitoring System

With the rapid development of Internet technology, the way of information dissemination has begun to shift to various network applications from traditional media, the amount and speed of information dissemination also has changed largely. People have more freedom of speeches because of technology development, some criminals, which maliciously destructs social stability and unity, use the Internet as a medium for distributing to the masses with the government’s remarks. But the vast majority of these comments are not from the local Government officially announced the official website or the media, which brought the masses a very bad influence, seriously affecting the status of the government, and undermined the government’s credibility among the people. Therefore, local government leaders made a decision that designing government public opinion monitoring system to find online all government-related remarks with research and the existing techniques. Effectively analyzing and monitoring these comments, the government could stop the bad dissemination of speech, correctly guide public opinion to maintain social stability.Based on the study of domestic and abroad research status about theory and application of public opinion, and learning the characteristics of similar products in the other units which have been running, the feasibility of the network public opinion monitoring system development is analyzed with the basic principles and methods of modern software engineering. Then the needs of various user roles are refined, and core business processing model are established. After completing the system architecture and functionality of the software design, the system functions are developed in Visual Studio2008platform with dot net Framework. Finally, the system is tested through scientific and rational test cases that could find potential errors that had been corrected at last, which could ensure the system to meet the require of reliability, ease of use and security.After nearly three months of operation in a real network environment, the results show that the system meets the Internet environment for application-specific address to effectively monitor, detect and stop the spread of harmful speech.
