Design And Implementation Of Internet Public Opinion Analysis Retrieval System

Internet public opinion information more and more emphasis on individual countries, but our a nalysis of public opinion means to make the face a greater threat to national security because of t he lack of effective. Hence the urgent need to retrieve public opinion analysis system to effectivel y monitor network public opinion, in order to purify the Internet environment, to prevent the occu rrence of adverse events, to avoid adverse consequences. Existing public opinion analysis retrieval system prevalent efficiency is not high, the lack of effective control measures and other shortcomi ngs. Therefore accelerate network public opinion research, and then to develop in line with China’s national conditions of Internet public opinion analysis retrieval system is very necessary. Its purpo se is real-time capture, storage, retrieval, analysis of network information, reach for emergencies, h ot sensitive issues warning. Users complete information browsing, download, analysis and other ope rations through user-friendly interface, and secondary analysis of public opinion, to retrieve the res ults obtained, a more effective and practical results of the analysis of public opinion.Thesis research are: discusses system design principles and technical support, including: multi-s erver clusters and distributed management, web crawlers and retrieval technology; in accordance wi th the principles of software engineering, completion of requirements analysis, system design and d etailed design of the overall structure; search algorithm design and system implementation. Main fu nction modules include: public opinion data acquisition module to complete the massive data collec tion and data preprocessing. The web page data collection stored in the data acquisition database, pre-processed data stored in the data pre-processing database; full-text search, which complete the pretreatment library Web page data classification, index, and the index to the processed data stored in the index database, and then complete the data retrieval operation; user interaction module, the results show the system to complete the network of public opinion, operation, configuration and o ther functions.Through the Internet public opinion analysis system can realize the network of public opinion information quickly capture, analysis, and by way of a secondary search results on public opinionfalse information to be screened, attention focused content and harmful information for analysis a nd early warning.
