ABSTRACT

In this paper, we propose a new methodology for authorship attribution based on a profile of indices related to the occupancy problem, called occupancy-problem indices. The occupancy problem has a long history and is an important example in standard textbooks like Feller (1971). We base our methodology on function words. We establish a testing procedure by constructing a confidence band of the occupancy-problem indices using the sampling distribution of the number of distinct function words. We validate our proposed methodology using controlled and constructed writing samples whose authorship is known. We then apply this methodology to explore the question of who wrote the 15^th Oz book, which has a disputing authorship between Lyman Frank Baum (1856–1919) and his successor Ruth Plumly Thompson (1891–1976) on the Oz series.

摘要

在本文中，我们提出了一种新的作者归属方法，该方法基于与占用问题相关的指标概况，称为占用问题指标。占用问题由来已久，是 Feller (1971) 等标准教科书中的一个重要示例。我们的方法基于功能词。我们通过使用不同功能词数量的抽样分布构建占用问题指数的置信带来建立测试程序。我们使用作者身份已知的受控和构建的写作样本来验证我们提出的方法。然后我们应用这种方法来探讨谁写了第 15^个问题Oz 书，Lyman Frank Baum（1856-1919 年）和他的继任者 Ruth Plumly Thompson（1891-1976 年）在 Oz 系列上的作者身份存在争议。
