摘　　要：为了使农民更加高效的获取农业知识,提出了一种基于改进规则引擎的农业知识系统。通过深入研究规则引擎的工作原理,将其引入到农业知识推荐系统中,增加了系统的正确性和准确性,使系统能够在最恰当的时间向农民提供他们最希望得到的正确的农业知识。同时根据农业领域的特点对规则引擎进行了改进,提出了规则库的树形结构化,并采用规则文件的运行前编译方式。将改进后的规则引擎应用于农业知识推荐系统中,提高了系统的效率。To make peasants get agricultural knowledge more efficiently,a agricultural knowledge recommendation system based on improved rule engine is presented.By studying thoroughly the rule engine＇s working principle and then applies to agricultural knowledge recommendation system,the accuracy and correctness of system is further increased.The peasants will get the right agricultural knowledge what they most want from the system at the most appropriate time.Meanwhile two methods are proposed to enhance the performance of rule engine according to the characteristics of agricultural field,which are compilation of the rules files out of process and tree structures of rule base.The sample tests indicated that the performance of the system is greatly improved when the improved rules engine is used to the recommendation system.
