Fuzzy matching routing filter in content-based publish/subscribe

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.
