摘要
针对分布式农业知识资源异构、自治和难以实现共享服务的问题,采用语义Web技术,提出了基于Web本体建模语言的异构农业知识资源描述模型和决策服务形式化表达模型。以模型为基础,将农业协同决策服务需求分解为多个决策流程片段,设计了基于上下文感知计算的农业问题协同决策服务机制,实现对多个决策流程任务和知识资源的按需调度,提高了农业知识资源的利用效率和协同推理效率。与其他方案不同,该机制进一步考虑了任务均衡分解与知识资源智能调度对协同决策服务机制的影响,并通过生猪疾病协同诊断决策系统的搭建进行了应用实例验证。实验表明,该方法在求解精度、决策效率方面优于传统农业智能决策方法。
The distributed agricultural knowledge resources have the characteristics of heterogeneous,autonomy and difficult to achieve shared services.Using of semantic web technology,a normalized of heterogeneous agricultural knowledge resources and the formal expression of the model for the decision-making service is proposed based on web-based ontology modeling language.Model-based,the agricultural collaborative decision needs are divided into multiple fragments and a coordination mechanism of agriculture decision are designed based on context awareness computing to achieve a number of tasks and knowledge resources on-demand scheduling,to improve agricultural efficiency and the efficiency of collaborative decision.Different with the other programs,the mechanism considers the effect of collaborative service decision-making mechanism,which is made by the balanced decomposition of assignment and the intelligent scheduling of knowledge resources to further.Additionally,it is verified by the building of the decision-making system of pig diseases collaborative diagnosis system.The results show that the method is superior to the traditional agricultural intelligent decision-making method concerning the accuracy and efficiency.
