Abstract

Abstract: Complex Event Processing（CEP） technology is a new technology which is applied in processing large volume primitive events and picking out valuable semantic events.In comparison with traditional events，RFID events have the following characteristics：large volume，temporal & spatial，inaccurate etc.It is necessary to do some researches on these characteristics and build an extensible CEP framework for RFID events.In this paper，the current researches on describing models，processing framework，parameter context，detecting method of RFID CEP are summarized.This paper picks out three problems of SASE and brings out some enhancing methods.These methods are proved efficient by some experiments.

Key words: RFID, complex events, detection, enhancement

摘要： 复杂事件处理（CEP）是一个新兴的技术领域，用于处理大量的简单事件，并从其中整理出有价值的事件。RFID事件和传统事件相比具有海量、时间性和空间性、数据不准确等特征。针对RFID事件的相关特征进行研究，建立一个可扩展的基于规则的RFID复杂事件处理系统是非常必要的。从复杂事件的描述模型、处理框架、上下文语义、检测方法等方面总结了国内外RFID复杂事件处理的研究现状，分析了目前的研究存在的不足，并且针对SASE的复杂事件算法存在的三点不足进行了改进。实验证明相关的改进对简单数据集是有效的。
