摘　　要：为有效提高农产品电子标签对追溯数据的识别能力,将事件本体模型思想引入到农产品质量安全管理领域,提出了一种基于本体的农产品电子标签中间件复杂事件处理引擎——ORFID-CEP,定义了RFID事件本体模型、语义空间和事件本体规则。在实际应用中边缘实时事件数量通常非常大,目前的方法难以满足大数据量实时事件的处理需求,造成了有意义事件的丢失。为了解决此问题,以事件本体模型和本体规则为基础建立了复杂事件本体活动的工作流转换机制,并提出了面向事件探测、事件操作和事件发生限制条件的优化策略,解决了RFID边缘处理的性能要求及高级事件逻辑需求。实验结果证明:在实际事件处理过程中,ORFID-CEP相比较传统的事件流处理引擎Esper-CEP,能够挖掘出更多更具语义信息的复杂事件,其稳定性更好;随着事件数量的增加,挖掘复杂事件的增长率要快于Esper-CEP,具有良好的信息处理能力。In order to improve the discriminating capacity of the RFID tags for agricultural product traceability data,a new handling engine ORFID-CEP for complicated events of agricultural product RFID Tag based on ontology,was proposed by introducing the event ontology model into the field of the agricultural product quality safety monitoring.In the new engine,the ontology model of RFID event,semantic space and the rules of the event ontology are defined.In the RFID practical application instances,the number of the fringe real-time events is so large that those methods used in current systems cannot handle them in time.Thus,many significant events are lost.Aiming to overcome the problem,the transform system of work flow for the complicated event ontology and the optimized strategies for event exploration, event operation and restrictive conditions of event appearance were established.Experimental results show that the new engine can mine more complicated events with semantic information than the conventional Esper-CEP engine. Additionally,the new engine is steadier than the Esper-CEP engine.With the increase of number of the events,the growth rate of the new engine for mining complicated events rises more quickly than that of Esper-CEP,which indicates that the engine has the good ability of information processing.
