Abstract This study described the functions of you know and I mean in contexts of academic seminar discussions by ELF speakers. The data used in the study consisted of the multicultural discussions in the corpus of English as a lingua franca in academic settings (ELFA). The approach of conversation analysis (CA) was used together with corpus techniques with the aim to provide quantitative support to function categorizations which were drawn from qualitative analysis. Results of the study not only demonstrated the multi-functionality of you know and I mean but also suggested that these two discourse markers played specific functions in academic seminar discussions under ELF contexts. In the context of cross-cultural and academic communication where problematic terms may occur, we found that you know was mainly used to achieve clarity, while I mean was primarily used to correct previous statements and dysfluencies. The findings of this study will help ELF speakers communicate more effectively in academic interactions by recognizing the functions of discourse markers and using them properly.

您知道的功能，我的意思是在ELF演讲者的学术研讨会讨论中

摘要这项研究描述了您所了解的功能，我的意思是在ELF演讲者进行的学术研讨会讨论中。研究中使用的数据由英语语料库中的英语语料库中的多元文化讨论组成（ELFA）。会话分析（CA）方法与语料库技术一起使用，旨在为从定性分析得出的功能分类提供定量支持。研究结果不仅证明了我所知道的多功能性，而且还暗示了这两种话语标记物在ELF环境下的学术研讨会讨论中发挥了特定的作用。在可能出现有问题的术语的跨文化和学术交流的背景下，我们发现您知道主要是为了获得清晰度，而我的意思是主要用于纠正先前的陈述和不当之处。这项研究的结果将通过识别话语标记的功能并正确使用它们，来帮助ELF演讲者在学术互动中更有效地进行交流。
