摘要
传统农业知识服务系统缺乏语义支持,并且在农业领域应用极为不足,本研究提出利用本体论和语义网知识建立知识服务系统的必要性。以茶叶领域为例,分析了生产过程中各类用户的实际需要,设计了适合农业生产实际的茶叶知识服务系统工作流程与主要模块,模块由三层架构组成:用户服务接口,知识服务平台以及知识库。描述了系统实现中的关键技术,如茶叶本体的构建方法,系统信息抽取算法以及系统的具体实现等,初步实现了系统功能。
By analyzing the status of traditional agricultural knowledge service systems,the shortcoming were pointed out,such as,lack of semantic support and application in the agricultural field.It was necessary to construct an agricultural knowledge services system based on semantic web and ontology.By analyzing the demands of all kinds of users in tea fields,the main module and workflow adapted to the actual production of tea were designed;the module was composed of three-tired structure：user service interface,knowledge service platform and knowledge base.A tea knowledge services system was initially realized,with the solution of some key technologies,such as the construction of tea ontology,information retrieve from internet,the syste marchitecture and development tools.
