Logistic regression analysis for function-to-form corpus building
Get PDFThis poster presents a method that uses logistic regression analysis to build a corpus for function-to-form research, focusing on the metadiscursive function, i.e., statements that refer to conditions, mechanisms and consequences of public discourse (Schröter, 2021, 2024). Corpus studies typically begin with form and move towards functional analysis, but this approach entails various challenges and limitations. To address these issues, O’Keeffe (2018) and Bender (2023) propose approaches such as qualitative reading and sifting of corpus samples or scaling manual annotation through machine learning. The method proposed here applies logistic regression to a manually annotated sample. After both internal and external validation, the model is used to automatically classify larger corpora, dividing them into subcorpora with and without metadiscursive statements. These subcorpora can then be analysed with standard corpus-linguistic methods

Statista (2022, n.d.). Bevölkerungsanteil mit COVID-19-Impfung nach ausgewählten Ländern weltweit (Stand: 20. Dezember 2022). https://de.statista.com/statistik/daten/studie/1203308/umfrage/impfstoffabdeckung-der-bevoelkerung-gegen-das-coronavirus-nach-laendern/Im vorgeschlagenen Vortrag wird eine vergleichende Diskursanalyse des Metadiskurses zum Mediendiskurs zur Corona-Impfung in Irland und der Deutschschweiz präsentiert. Damit werden zwei Diskursgemeinschaften verglichen, in denen ähnliche Maßnahmen zur Eindämmung der Coronapandemie getroffen wurden, sich aber die Impfquote drastisch unterscheidet (Statista, 2022). Da Diskurse auf handlungsleitendes Wissen verweisen (Spitzmüller/Warnke, 2011), kann davon ausgegangen werden, dass der Mediendiskurs über die Corona-Impfung sowie die Rezeption desselbigen die Impfentscheidung maßgeblich beeinflusste. Mithilfe der Metadiskursanalyse können Unterschiede im Mediendiskurs und dessen Rezeption aufgezeigt werden. Unter Metadiskurs werden alle sprachlichen Zeichen(-ketten) verstanden, mit denen Aussagen über den Diskurs getroffen werden, z.B. die Problematisierung von Begriffen oder Verweise auf Leerstellen. Wie auch bei einer Diskursanalyse stehen Merkmale wie Intertextualität und Rekurrenz der Aussagen im Zentrum (Schröter, 2021). Der Fokus des Vortrages liegt auf der Modellierung der vergleichenden Metadiskursanalyse, insbesondere auf der Herstellung funktionaler Äquivalenz in Bezug auf Quellen und Suchbegriffe. Außerdem werden korpuslinguistische Methoden zur Untersuchung des Metadiskurses gezeigt und erste Ergebnisse präsentiert

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
