A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc

Robustness of Triple Sampling Inference Procedures to Underlying Distributions
No full textIn this study, the sensitivity of the sequential normal-based triple sampling procedure for estimatingthe population mean to departures from normality is discussed. We assume only that the underlyingpopulation has finite but unknown first six moments. Two main inferential methodologies areconsidered. First point estimation of the unknown population mean is investigated where a squarederror loss function with linear sampling cost is assumed to control the risk of estimating the unknownpopulation mean by the corresponding sample measure. We find that the behaviour of the estimatorsand of the sample size depends asymptotically on both the skewness and kurtosis of the underlyingdistribution and we quantify this dependence. Moreover, the asymptotic regret of using the triplesampling inference instead of the fixed sample size approach, had the nuisance parameter beenknown, is a finite but non-vanishing quantity that depends on the kurtosis of the underlyingdistribution. We also supplement our findings with a simulation experiment to study the performanceof the estimators and the sample size in a range of conditions and compare the asymptotic and finitesample results. The second part of the thesis deals with constructing a triple sampling fixed widthconfidence interval for the unknown population mean with a prescribed width and coverage whileprotecting the interval against Type II error. An account is given of the sensitivity of the normal-basedtriple sampling sequential confidence interval for the population when the first six moments areassumed to exist but are unknown. First, triple sampling sequential confidence intervals for the meanare constructed using Hall’s (1981) methodology. Hence asymptotic characteristics of the constructedinterval are discussed and justified. Then an asymptotic second order approximation of a continuouslydifferentiable and bounded function of the stopping time is given to calculate both asymptoticcoverage based on a second order Edgeworth asymptotic expansion and the Type II error probability.The impact of several parameters on the Type II error probability is explored for various continuousdistributions. Finally, a simulation experiment is performed to investigate the methods in finite samplecases and to compare the finite sample and asymptotic results
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
