摘　　要：群体感知理论和实现技术是计算机支持的协同工作中必不可少的组成部分。文章分析研究了群体感知理论研究工作的现状,介绍了一种基于任务的群体感知模型TAM。该模型通过对收集来的感知信息按基本要素“任务”进行分解、处理(加权)、再组合,精确描述群组任务的每个变化,并且获得相应的感知强度,有效地解决了现有的群体感知模型存在的不足。该文给出了该模型的建模思想和总体结构,并从该模型的基本概念、任务收集、任务分解、感知强度、任务整合等方面给出了该模型的形式化描述。文章最后讨论了在下一步研究中仍需解决的一些问题。The theory of group awareness and the realization skill is an absolutely necessarily portion in Computer Supported Cooperative Work（CSCW）.After analyzing and studying the research state of the theory of group awareness at the present time, a task-based group awareness model called TAM is introduced in this paper.This model disassembles the aware information collected before,manages the aware information （adding right to it）and assembles them.So,every changes of the task in the group can be described particularly in this model,and the awareness intensity has been attained too.The model of TAM mends the weakness of existing group awareness models effectively.Firstly,the modelling ideas and the architechure of the model are given out in this article.After that,from several sides,such as,basic conception,task-collection,task-disassembling,awareness intensity,task-assembling etc.,the model is described with form al language in the paper.Finally,some related questions in the future research are discussed.
