Design And Implementation Of Automatic Categorization System Of Public Security Information

With the development of Internet network, the information data of the Internet become more and more abundant, it become the largest data resources of the world, the public security organ which collect intelligence work is also slowly spread through using the method. In order to achieve the classification function quickly and automatically, we need to improve the performance of classification and reduce the costs in the artificial identification models, it has the great significance to research and development an kind of automatic categorization system of public security information.According to the characteristics and requirements of classification function of police intelligence system, the SVM theory and the classification technique are analyzed and studied, meanwhile it based on the technique to design the system, the performance characteristics of the system was optimized, the tests showed that the system has good practical application.Firstly, this thesis introduces the status and development of police intelligence system, analyzes the practical significance of the system. Then this thesis introduces the key technology in the process of implementing. The network data resources is mostly the organizational structure of the text. This thesis designs the data mining and the application of support vector machine. The man-machine interface design uses object oriented component technology, it uses database technology etc. Again, analyzing the actual needs and characteristics of information classification system, text describes the main realization function module through the demand analysis. Then it designs the information of system architecture. It includes information synchronization engine. A kind of system information collection and a kind of standard mode. Synchronization tool is designed in this thesis to establish the information source, it make different departments achieve the different information resource database. At the end, it tests and validates every function module of the system. The results show that the public security intelligence and the design of automatic categorization system of public security information has reached the functional requirements and performance requirements.
