线性文本分割旨在自动标记文本中的话题转换位置，是自然语言处理中一个成熟的研究领域，基于语言学与计算语言学的理论基础。随着网络上文本、视频和音频数据激增，内容需高效摘要与分类，该任务成为关键步骤。本文全面综述了线性文本分割的最新进展，涵盖当前可用资源与主流方法。最后，指出现有数据资源的局限性及任务本身的不足，并基于最新文献提出未来研究方向与未充分探索的路径。
原文摘要 · Abstract (English)
Linear Text Segmentation is the task of automatically tagging text documents with topic shifts, i.e. the places in the text where the topics change. A well-established area of research in Natural Language Processing, drawing from well-understood concepts in linguistic and computational linguistic research, the field has recently seen a lot of interest as a result of the surge of text, video, and audio available on the web, which in turn require ways of summarising and categorizing the mole of content for which linear text segmentation is a fundamental step. In this survey, we provide an extensive overview of current advances in linear text segmentation, describing the state of the art in terms of resources and approaches for the task. Finally, we highlight the limitations of available resources and of the task itself, while indicating ways forward based on the most recent literature and under-explored research directions.
