中文摘要： 信息物理系统（CPS）是推动21世纪IT变革和数字化生活的重要研究领域，事件是CPS中物理数据到逻辑语义的重要元素，交互式事件处理对于CPS的可用性具有重要意义。本项目主要研究内容：（1）交互式事件处理模型研究，包括模型建立和消耗策略扩展。满足信息世界的事件和物理对象行为之间的互动需求。（2）自适应规则集构建，包括动态规则集建立方法，融入情境信息的反馈规则调整，事件规则冲突消解策略和冗余规则消除方法。（3）交互式事件探测方法，包括基于引入语义的事件合成方法，非自发事件的合成方法，以及利用反馈控制的事件模式调整方法，语义片段共享事件合成优化方法，提高事件探测的效率。（4）交互事件乱序处理，消除乱序给事件带来的歧义性.（5）建立一个原型系统，以整合CPS事件处理技术。创新点在于充分考虑CPS中事件的交互性、情境相关性，利用反馈控制技术，结合并改进主动数据库中的技术。

英文摘要： The cyber physical system (CPS) is an important research area for the IT revolution and digital life in the 21st century. In the CPS, event plays an important role for the transformation from the physical data to the semantic model. It is significant to study the interactive event processing to guarantee the usability of the CPS. The project mainly includes the following aspects: (1) The interactive event processing model. It would build a perfect model and expand the consumption strategy, so as to satisfy the interactive demand between the events in cyber world and the behavious of the physical objects. (2) The adaptive construction techniques of the rule set. They include: the construction method for the dynamic rule set, the adjustment method of the feedback rules according to the cotext information, and the elimination method for the contradictory rules and redundant rules. (3) The interactive event detection techniques. They include: the event composing method based on semantic, the composing method for the non-spontaneous events, the adjustment method for the event patterns based on the feedback control，and the optimazion algorithm for compounding events which share the same semantic. (4) The out-of-order processing for the interactive event is to eliminate the ambiguity caused by the out-of-order events.
