中文摘要：

在开放式群体决策研讨过程中，为了有效克服简单的文本记录方法和信息显示方式给群体交流带来的不便，克服在研讨过程中存在的“知识断层”和“信息过载”，改善交流效果并最终有效地辅助决策，需要探索集文本、音频和视频等多媒体为一体的研讨信息可视化显示方式。在分析群体成员对研讨信息可视化需求的基础上，提出了研讨信息自主可视化的概念，建立了基于UML的群体研讨信息自主可视化模型。最后，给出了相应的实现模式和一个简单的群体研讨信息自主可视化平台示例。

英文摘要：

In the open group decision argumentation, the visual display mode of argument information which aggregates the text, the audio and the visual display modes should be explored, to overcome the inconvenience resulted from the dependence of simple text display mode, to conquer the ＂information overload＂ and ＂knowledge gap＂ in argumentation, to improve communication and assist final decision. In this paper, we analyze the need of the information visual display mode from the argument member. On this basis, the concept of argument information independent visualization is brought forward. Then an UML- based independent visual model of group argument information is given. Finally, a relevant realization mode is suggested, a simple system of the independent visualization of group argument information is giw an.
