中文摘要：

现有的RFID复杂事件处理模型，如基于Petri网的模型、基于树的模型、基于图的模型、基于自动机的模型，并不能十分有效地解决复杂的RFID应用问题，具体地说，RFID复杂事件的语义分析方面缺乏进一步的研究。针对上述问题，提出了一种RFID复杂事件语义分析方法。该方法借鉴编译原理中的语义分析技术，为事件增添定义了继承属性和综合属性，同时按照事件之间的关系定义了三种语义模式，最后通过一个语义解析算法解析出特定模式组合的语义信息。实验证实该方法取得了比较理想的效果。

英文摘要：

The exising models,such as the model based on Petri-net,the model based on tree ,the model based on graph ,the model based on automa, can not be effectively used in RFID application s. Specifically , there are not enough researches on thesem antics about the RFID com plex events. Considering o f the p ro b le m ,this paper proposed an analysis method of the semantics.The m ethod was based on the tra nslation technology about the compiler principle . In this method ,it defined the inherite dattribute s and synthesized attribute s o f events. Besides ,it defined three patterns according to the relations o f events and proposedthe algo rithm o f sem antics5 analysis. Finally ,it parsed some valuable sem antics according the algo rithm . The m ethod isproved by experim ents to be effective.
