本文借助自然语言处理技术构建了日语语篇衔接指标体系，探讨了不同母语背景高级日语学习者语篇衔接能力习得情况。研究表明，学习者在词语重复、语义重复、连接词、指代等四个衔接层面与母语者存在一定差距。通过计算母语者作文与学习者作文衔接指标的欧氏距离发现，与中国学习者相比，韩国学习者的作文语篇衔接表现更加接近日语母语者，原因是韩语与日语相似。这一发现可为语言迁移理论的完善提供来自中国、韩国外语学习者作文语篇衔接方面的证据。

This study utilizes natural language processing (NLP) technology to construct a Japanese discourse cohesion index system. It then investigates the acquisition of discourse cohesion in Japanese by advanced learners with different native languages, specifically Chinese and Korean. The findings reveal discrepancies between the essays written by advanced learners and those written by native speakers in aspects such as lexical overlap, semantic overlap, connectives, and references. By calculating the Euclidean distance between the cohesion indices of native speakers’ essays and those of language learners, it is observed that, compared with essays written by Chinese learners, those written by Korean learners are more cohesive and closer to those written by native speakers. This phenomenon can be attributed to the similarities between Korean and Japanese. This discovery enhances the theory of language transfer by providing empirical evidence from discourse cohesion in the essays written by foreign language learners from China and Korea.
