面向在线群体研讨的言语行为分类体系设计框架研究

A Design Framework for Speech Act Taxonomy of Online Group Discussion

缺乏言语行为分类体系及其构造方法论,已经成为国内言语行为自动化分析研究的一个主要障碍。以信息系统设计理论为指导,提出言语行为分类体系的设计需求,并以流程为人造物的观点,研究设计出一个包含5个关键步骤的迭代流程来满足设计需求。进一步以该方法论为指导,以E-learning环境语料为案例,提出一个适合在线问答研讨的言语行为分类体系,并验证该体系的辨别能力和泛化能力。E-learning语料环境的应用结果表明,该言语行为分类体系构造方法论具有较好的效果。

The lacking of studies on speech act analysis in Chinese context can be attributed to the short of speech act taxonomies.This research follows the paradigm of design science by proposing the design requirement for speech act taxonomy,and develops an iterative process that contains five steps to satisfy the design requirement.Further,the authors develop speech act taxonomy for E-learning environment based on the proposed methodology,and evaluate its discernment and generalization ability.The successful application in E-learning environment validates the effectiveness of proposed design framework for speech act taxonomy.
