Abstract

ABSTRACTThe paper is developing a new statistical approach to automatic partitioning of texts into parts belonging to different authors. It is based on the analysis of processes that counts the number of different words forward and backward. The theoretical study of the processes is based on the assumptions of an elementary probability model with a change point. We prove consistence of our statistical estimate of the point of concatenation in the case when the concatenated texts have different Zipf exponents. This method is being tested on the Brown corpus and also on newspaper texts in different languages. Testing shows a good estimate of the concatenation point. This method can be used in parallel with other text segmentation methods. AcknowledgmentsThe authors like to thank anonymous referees for their helpful and constructive comments and suggestions.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementWe used texts from open sources.Additional informationFundingThe work was supported by the Siberian Branch, Russian Academy of Sciences [FWNF-2022-0010].

通过向前和向后计数不同单词数量的过程进行文本分割

摘要本文提出了一种新的统计方法，用于将文本自动划分为属于不同作者的部分。它基于对进程的分析，向前和向后计算不同单词的数量。该过程的理论研究是基于一个具有变化点的初等概率模型的假设。我们证明了在连接文本具有不同Zipf指数的情况下，我们对连接点的统计估计的一致性。这种方法正在布朗语料库和不同语言的报纸文本上进行测试。测试显示了对连接点的一个很好的估计。该方法可以与其他文本分割方法并行使用。作者要感谢匿名审稿人提供的有帮助和建设性的意见和建议。披露声明作者未报告潜在的利益冲突。数据可用性声明我们使用了来自开放资源的文本。本研究得到了俄罗斯科学院西伯利亚分院的支持[FWNF-2022-0010]。

期刊介绍： The Journal of Quantitative Linguistics is an international forum for the publication and discussion of research on the quantitative characteristics of language and text in an exact mathematical form. This approach, which is of growing interest, opens up important and exciting theoretical perspectives, as well as solutions for a wide range of practical problems such as machine learning or statistical parsing, by introducing into linguistics the methods and models of advanced scientific disciplines such as the natural sciences, economics, and psychology.
