摘    要：基于模糊匹配的优化思想，设计基于内容的发布/订阅模糊匹配路由过滤器，对基于覆盖路由的模糊匹配过滤器的构造原理、模糊函数的构造和匹配规则、属性的隶属度函数和匹配阀值进行研究，并给出模糊匹配过滤器的算法描述和实验结果。研究结果表明：采用模糊匹配算法对属性进行过滤，可以快速找到符合订阅要求的发布事件消息，有效地提高系统性能。

Abstract: Based on fuzzy matching, a fuzzy matching routing filter in content-based publish/subscribe was designed. The structural principle of fuzzy matching filter covering routing, the structure and matching rules of fuzzy functions were discussed. The membership function of attribute and the threshold to judge whether the matching was successful or not were represented. An algorithm about fuzzy matching filter was put forward and experimental results were given out. The result shows that the algorithm can be used to find the publishing event quickly that matches the subscription. The fuzzy matching routing filter can increase the capability of system effectively.
