摘　　要：由于FIPA结构的本体知识库在信息的更新和查询过程中存在处理时间过长、平台与知识库不兼容、过分依靠外部构件和不支持C-S模式等问题,在基于FIPA结构的知识库中,根据其内部构件支持HTTP协议的特点增加三种机制:(1)将信息以三元组的形式存储在Meta本体中;(2)将操作后的确认信息记录在rdftp;(3)存储本体信息与其对应的本体之间的虚拟地址与物理地址的映射关系,提出了使用HTTP协议中的命令来实现对知识库信息的操作的策略。从而使知识库减少了对信息处理的时间开销、支持C-S模式并且不需要依赖其辅助其他构件。通过对时间复杂度的比较,验证了该策略的可行性和有效性。In the process of modification and query of the information on Ontology Repository based on FIPA structure, there are some problems, such as spending too much time to complete this process, it can not be used by many platforms, relying too much on some components that do not belong to itself and it can not support C-S model. So, according to internal components＇ trait of supporting HTTP protocol. It makes use of some orders from HTTP protocol through creating three new mechanisms as following： （1）. storing information of Ontology according to tri-unit form, （2）. storing the information about each process, （3） storing the information between physical address and virtual address. Because of this innovation, it achieves this strategy that using orders to complete the whole process of manipulation of the information on the Ontology Repository. As a result, it is able to reduce the cost of the process, support C-S model and never use any external components. It is proved to be more stable and more rational.
