With the development of Internet technology, the network has become an important place in the emergence and development of public opinion. Network public opinion information effectively present attitude and netizen hot topic of current people pays close attention to, and then reflect the state of development of the current social, political, economic and other. Therefore, through the acquisition of network public opinion, information analysis and management to grasp has important practical significance to guide the network public opinion public opinion trends and current development. This paper has mainly carried on the research of network public opinion, and on the basis of the analysis of network public opinion and management system design and implementation. The main contents include the following aspects:1.network public opinion information acquisition and information processing technology is the basis of network public opinion analysis, refers to the use of web crawler webpage and intelligent processing of webpage collected. The second chapter introduces the basic idea and process of Internet public opinion information acquisition and information processing technology[18] [19].2.the topic detection and topic tracking technology research is the core of public opinion analysis, classification of unknown topic clustering and book topic pointer. The third chapter focuses on the topic detection, topic detection algorithm based on the current, and proposed an improved single-pass clustering algorithm, the main idea of the algorithm is as follows: moral consideration to a combination of proper nouns can distinguish the topic center, therefore in the feature extraction process, using the method given a higher weight a plurality of proper noun combination; in addition to the similarity comparison process, first of all the document title feature vector similarity comparison to divide your topic center, so that the hierarchical presentation of public opinion analysis results.3.There are many types of opinion analysis inland. Most of them can real-time monitoring the network information and collect, analysis and release the network information by using information retrieval and text mining. To implement public opinion finding and following up from the perspective of text processing, Multi-level evaluation technology is not provide. In hot characteristics evaluation aspects, popular word discovery method can be drawed lessons, calculated from events document frequency and the average similarity of two points of view of quantitative. A large number of algorithms can accessing information, topic detection and tracking technology,4.the network of public opinion analysis and management system design and implementation. The general framework of the system is determined, public opinion on the network information collection, information processing, analysis of public opinion, public opinion warning and management function module design, and public opinion on the network information collection, information processing and public opinion analysis module to realize. The system has certain practical significance in the application of network public opinion. The network public opinion, such as the construction of evaluation index system and evaluation value calculation have just started, so this paper dose a research on multithreading public opinion,the construction of evaluation index system, the network public opinion topic evaluation and value calculation and the establishment of early warning model of network, etc. according to the characteristics of the network public opinion...
