Title Social information gathering public opinion research public opinion research community
Abstract Sina microblogging is a providing the public with entertainment life service information sharing and exchange platform. As the population more gathering place, a social public opinion detected a significant accumulation point. Sina microblogging is exclusive information released by the best platforms. Sina microblogging sense is "never closed the press conference," Sina microblogging has become a media monitoring and tracking breaking news of the important sources. However, the Internet is enormous information confused, if just by manual inspection of social public opinion, heavy workload, and inefficient, so the design one for Sina microblogging public opinion detection system is very necessary. The system is designed and implemented the social public opinion Systems Web crawler part with keywords relevant to the subject of the state and comments entered into the database, in order to ensure the integrity of the system, using jsp technology, the resulting data is presented in the database. In this thesis, the main contents are: (1)A study of several typical crawling strategies, analyzes their characteristics, for common reptiles shortcomings, we propose a practical and efficient for Sina Weibo precise theme reptile design method for Sina microblogging characteristics, using the template configuration method, the Sina microblogging information for analysis and crawl. (2) of the system used by the various components of a brief introduction. And system design concepts and the specific module implementation is introduced. (3)for the proposed public sentiment prediction algorithm was simulated tests, the test to verify the feasibility of the algorithm. This realization reptiles not only meet the development team related to their daily work needs, but in terms of performance, accuracy, and overall rates are superior to common reptiles. The system can quickly respond to network emergencies to provide support and help.
