Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
West meets East: Papers in historical lexicography and lexicology from across the globe
Full text linkSynopsis:
Lexicography, in its many forms, is a very old, practical discipline solving practical problems concerning word usage. The term “word” seems more appropriate than “language” in this context, as lexicography addresses more questions relating to what we now call lexicology. As with all areas of human endeavour, what developed gradually through trial and error has eventually been subjected to a theoretical framework. The role of historical lexicography is to look back on the development of these highly varied word lists to understand how we arrived at the tremendous variety that characterises practice throughout the world.
This volume is both a selection of expanded papers from one conference on historical lexicography and lexicology, held under the aegis of the International Society for Historical Lexicography and Lexicology (ISHLL) in Lorient, France, in May 2022, and also the first in a new book series dedicated to the field. The new series represents a collaboration between two sister associations, ISHLL and the Helsinki Society for Historical Lexicography (HSHL). The volume contains texts in both English and French that provide insights into dictionaries, their compilers and users using evidence from numerous languages across the globe. It is also diachronic, moving from topics on medieval usage to contemporary issues concerning open access and digital publishing in historical lexicography. The title reflects the global scope of its authors and content, encompassing Japan to the United States, Eastern Europe to the United Kingdom, and Portugal
Variations on the Author
Full text link“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
Full text linkWe 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
