摘要： 为了提高网络信息过滤的准确率,引入了模糊评判,通过将模糊评判与向量夹角余弦相结合的方法,改进了求目标信息空间与待过滤信息空间之间相似度的Sim函数,并将该方法应用到所设计的网络信息过滤系统中,验证了改进的有效性。
关键词: 信息过滤, 模糊评判, 网络安全, Sim
Abstract: In order to increase the precision of information filtering ,this paper has brought in the fuzzy judgement theory to improve the function which is used to compute the similarity between the object information space and the filtering information space,by means of combining the fuzzy judgement result and cosine value of two vectors’angle.Then,applied the improved function to the information filtering system and proved the validity of the improvement.
Key words: information filtering, fuzzy judgement, network security, Sim
