Design of network information filtering system based on data mining technology

对网络信息进行过滤,在提高网络安全性能方面具有重要意义。传统网络信息过滤系统一直存在信息过滤不完整、效率差的问题,故提出并设计基于数据挖掘技术的网络信息过滤系统。网络信息过滤系统硬件主要由数据采集模块、数据处理模块、数据分析模块、控制界面模块和过滤及反馈模块组成,在过滤及反馈模块引入数据挖掘技术,对各个重要数据进行分析,并给出部分软件代码,实现网络信息过滤系统的优化。实验结果表明,以调和平均值为指标,对改进设计系统进行验证,其查全率及查准率的调和平均值较高,具有一定的优势。

Network information filtering is of great significance in improving network security performance.As the traditional network information filtering system has the long-existing problem of incomplete and inefficient information filtering,a network information filtering system based on the data mining technology is proposed and designed.The hardware of the network information filtering system is mainly composed of the data acquisition module,data processing module,block data analysis module,control interface module,and filtering and feedback module.In the filtering and feedback module,the data mining technology is introduced to analyze various important data and present part of software codes,so as to realize the optimization of the network information filtering system.The experimental results show that,with the harmonic mean value as the index,the improved design system is verified to have a relatively high harmonic mean value of the recall ratio and precision ratio,which has a certain advantages.
