搜索网络中虚警干扰内容隔离技术研究仿真

On Simulation of Virtual Police Interference Isolation Technology in Searching Networks

在搜索性网络优化设计的研究中,对危险内容的目标搜索往往需要对相关内容设定固定的阀值,以保证搜索引擎在安全范围内搜索。但是,一些网络冗余内容中存在与危险内容类似的信息,造成阀值接近。传统的搜索方法在解决上述问题的过程中,虽然可以采用非固定特征过滤,但是一些虚警干扰往往与真实特征具有高度相似性,很难运用固定区间的阀值区进行描述,造成搜索虚警。为此提出采用加权约束残差修正算法的搜索网络中虚警干扰隔离方法。针对搜索网络中不同的虚警干扰特征进行分类处理,获取干扰特征的分布状态,并且针对所有的干扰特征进行变异处理。根据加强约束残差修正算法相关理论,计算虚警干扰特征的方差矩阵,得到对应的虚警干扰特征子空间,获取搜索网络中的干扰特征,并进行加权约束残差修正处理,实现虚警干扰隔离。建立搜索模型,实现搜索网络中的目标搜索。实验结果表明,利用改进算法进行搜索网络中虚警干扰隔离,能够保证隔离效果,最终得到理想的搜索结果。

A virtual police interference isolation method is presented based on weighted constraint residual error correction algorithm in search networks. The interference characteristics of different false alarms in web searching are classified, the interference characteristics of distribution are obtained, and all the interference characteristics are processed by variation. According to the related theory to strengthen the constraint residual correction algorithm, the covariance matrix of the false-alarm interference characteristics is calculated, the subspace of corresponding false-alarm interference feature is got, the interference characteristics of the search network are obtained, the weighted constraint residual correction is processed, and the false alarm interference isolation is realized. Search model is set up, and the search target in the search network is achieved. Experimental results show that the improved algorithm can ensure the isolation effect.
