摘　　要：针对用户在利用现有即时消息系统的在线感知模块所提供的感知信息寻找正确交互对象时碰到的问题,通过分析现有的基于XMPP即时消息系统结构和在线感知实现的基本方法,结合在现有XMPP客户端中加入收集用户事件信息组件进行数据的收集,并利用决策树的分类算法对收集数据进行处理,从而实现一种可以预测的用户回应可能性的动态在线感知模型,最后利用仿真实验的方式,对模型进行了仿真分析和验证,从而得出在XMPP协议的即时消息系统中实现这种可预测用户回应的动态的在线感知模型的是可行的(其准确率约为90%),与现有其他在线感知功能模块相比,运用该方法实现的模型由于引入了预测用户行为的动态感知,因此用户在利用该模型寻找正确交互对象时的效率更高,并被用于国家网络科技环境建设的多个项目中,收到了良好效果。This paper is focused on how to solve the problem that users may face when they want to seek the right person to interact, and giving an analysis of the structure of current instant messaging systems and the implementation approach of on - line awareness module in such an instant messaging system based on XMPP. A method of adding a new module is used to collect the data about the user events. This paper also uses an algorithm of the decision tree classification to process the collected data, and finally implements a module that can be used to predict the responsiveness from his buddies, and an emulating method is adopted to validate the module＇s accuracy. The conclusion is that it is possible and useful to add such a new module in instant messaging system. Now Comparing to the current on - line awareness module of instant messaging system, this module firstly imports the dynamic awareness concept that can predict the users action, so it is more efficient to use this module to seek the right person to interact.
