Several authorship analysis tasks require the decomposition of a multiauthored text into its authorial components. In this regard two basic prerequisites need to be addressed: (1) style breach detection, i.e., the segmenting of a text into stylistically homogeneous parts, and (2) author clustering, i.e., the grouping of paragraph-length texts by authorship. In the current edition of PAN we focu...

The authorship of the 1924 short story ‘The Loved Dead’ has been contested by family members of Clifford Martin Eddy, Jr. and Sunand Tryambak Joshi, a leading scholar on Howard Phillips Lovecraft. The authors of this article use stylometric methods to provide evidence for a claim about the authorship of the story and to analyze the nature of Eddy’s collaboration with Lovecraft. Further, we exte...

In the history of authorship attribution, the analysis of The Federalist Papers plays an important role. However, most previous non-traditional (stylistic) authorship studies have been flawed, mainly due to the use of improper editions, as documented by Rudman (2005). Our goal in this work was to perform a correct study by using a revised corpus of the Federalist papers based in large part on R...

Authorship verification is the task of determining if a given text is written by a candidate author or not. In this paper, we present a first study on using an anomaly detection method for the authorship verification task. We have considered a weakly supervised probabilistic model based on a multivariate Gaussian distribution. To evaluate the effectiveness of the proposed method, we conducted e...

OBJECTIVES The purpose of our study was to investigate authorship trends in radiology journals, and whether International Committee of Medical Journal Editors (ICMJE) recommendations have had an impact on these trends. A secondary objective was to explore other variables associated with authorship trends. METHODS A retrospective, bibliometric analysis of 49 clinical radiology journals publish...

We read the publication by Liu (2016) on authorship misconduct with a great interest. In fact, the authorship misconduct is no uncommon and has to be managed. Liu (2016) noted that “Proper authorship embodies honesty, integrity, fairness and transparency, which surely are the very essence of any scientific pursuit.” Due to the present requirement on academic publication to support academic rank...

Authorship attribution is associated with important applications in forensics and humanities research. A crucial point in this field is to quantify the personal style of writing, ideally in a way that is not affected by changes in topic or genre. In this paper, we present a novel method that enhances authorship attribution effectiveness by introducing a text distortion step before extracting st...
