Web内容过滤实现方法的研究

介绍了Web内容过滤的技术原理以及如何通过防火墙实现的方法。通过所设计的"内容过滤模型"体现出"用防火墙实现内容过 滤"的优势。该模型把URL过滤和文本关键词过滤二种技术相结合。在不降低过滤精度的基础上提高了过滤速度。还论述了对经典过滤算法 以及参数设置的改进,最后以实例介绍在防火墙上的实现方法。

Research on the Implementation of Web Content Filtering

This paper presents the technical principle of Web content filtering and the implementing method on the fire wall and designs a content filtering model to show the advantage of the implementing on the fire wall. This model combines the URL filtering and text keywords filtering technic, discusses how to improve the classical filtering algorithm and the parameter value. This technic improves the filtering speed and doesn't deteriorate the filtering precision. Finally, it introduces how to implement it on the fire wall.
