越来越多的公司在招聘员工时强调沟通技巧，并采用小组讨论作为招聘面试的一部分。在我们正在进行的项目中，我们的目标是开发一个培训系统，可以提供建议，以提高其用户在小组讨论中的沟通技巧的看法。为了实现这一目标，需要一个概念单元或沟通风格的模板。在本文中，我们建议使用小组讨论的参与者的功能角色作为这个单元，并报告了调查结果的支持系统中采用功能角色的相关问题。首先，我们定义的功能角色被认为是适合于此目的，并表明这些角色的分布确实决定了个人参与者的沟通技巧的印象。为了将功能角色的特征融入到实时支持系统中，系统需要从计算机能够处理的低层信号中检测出参与者的功能角色。在本文的第二部分中，我们提出了一个基于机器学习技术的检测模型，并证明了这是可能的。参与者的功能角色的时空模式的动态变化及其与沟通技能的关系可以为支持系统的策略提供线索。在本文的第三部分中，我们假设当前的“会话情境”可以由参与者的功能角色的组合来表示，并对它进行了分析。然后，我们分析了模式的下一个角色的现状，关于高沟通技能的参与者和低的。从结果中，我们发现，在讨论中更活跃的参与者通常被评价为高技能。
More and more companies are putting emphasis on communication skill in the recruitment of their employees and adopt group discussion as part of recruitment interview. In our ongoing project, we aim to develop a training system that can provide advices to its users in improving the perception of their communication skill during group discussion. In order to realize this goal, a conceptual unit or a template of communication style is required. In this paper, we propose the use of functional roles of the participants in group discussion as this unit and report the investigation results on the issues related to adopting functional roles in the support system. At first, we define the functional roles which are considered to be appropriate for this purpose and show that the distribution of these roles indeed determines the impression of individual participant's communication skill. In order to incorporate the feature of functional roles into a real-time support system, the system needs to detect the participants' functional roles from low-level signals which can be processed by computers. In the second part of this paper, we propose a detection model with machine learning techniques and show this is possible. The dynamics of the spacial and temporal patterns of the participants' functional roles and their relationship with communication skill can be considered to provide hints for the strategy of the support system. In the third part of this paper, we assume that the current “conversational situation” can be represented by the combination of the functional roles of the participants and conducted the analysis on it. We first analyzed the relationship of the transitions of conversational situations and communication skill. We then analyzed the patterns of the next role of the current situation regarding to high communication skill participants and low ones. From the results, we found that the participants who were more active in the discussion are generally evaluated with high skill.
