一种基于改进Rocchio的网络信息过滤反馈算法研究

随着互联网上信息的迅速增长,网络安全日益引起人们的关注。提供一定手段管理网络用户,尤其是青少年用户具有十分重要的意义。本文利用向量空间模型,Rocchio方法生成类别过滤模板,采用余弦算法比较待过滤文档和类别模板的相似度,并提出一种利用反馈动态修改模板的反馈机制。实验表明本文提出的反馈方法是切实可行的。

Research on an Improved Rocchio Based Network Information Feedback Algorithm

Network security is increasingly important with the rapid growth of the information on the web,so it is very significant to provide a certain method to administer network users,especially younger users.This paper presents an approach that of generating category filtering templates with a vector space model,the method of Rocchio,employs cosine algorithm to compute the similarity between documents for filtering and category filtering templates,and proposes a dynamic feedback mechanism to amend the category templates.Experiment shows that the feedback mechanism is practicable.
