Diachronic change from Washington to Obama: the challenges and constraints of corpus-assisted meaning analysis
No full textBuilding on previous findings investigating diachronic change in specialized domains, in particular State of the Union addresses over a long-term time span (Bayley and Bevitori 2015), this chapter aims at exploring what can and, conversely, cannot, be achieved by combining Corpus Linguistics procedures with the analysis of texts and discourse within the theoretical concerns of Systemic Functional Linguistics. Moving beyond textual ‘aboutness’, it is argued that certain kinds of lexicogrammatical information can be detected through the analysis of a non-annotated corpus; moreover, with particular reference to the case-study, it will also be claimed that the rhetorical thrust of State of the Union addresses has gradually, but consistently, shifted from a more ‘informative’ style, i.e. presenting a report, to a more ‘persuasive’ one, i.e. soliciting action, over time
Editorials and Opinion Articles in the CorDis Corpus: A Transversal Study
No full textThe research in this chapter builds on previous work that has distinguished linguistic features of the discourse type opinion articles, frequently called ‘op-eds’, from other types in media discourse, such as editorials and newspaper reports. Starting from Biber’s lists of features involved in the ‘overt expression of persuasion’ (1988:195), Murphy and Morley (2006) documented characteristic features of op-eds in terms of the frequency of first and second personal pronouns, verbs indicating mental and verbal processes, and lexical density. In the present paper, by quantitative and qualitative means, the subcorpora of opinion articles and editorials (PapOp and PapEd) from the CorDis Corpus are compared and contrasted across two different parameters, popular papers versus quality papers, and British versus American papers, with the aim of making finer distinctions between the two discourse types. Three broad issues are approached. Firstly, aspects of spoken discourse such as interjections, vocatives, discourse markers, contracted forms, and first-person imperatives are sought and explored in the two discourse types; this section is a development of research by Murphy
and Morley (2006) which reported that, from the point of lexical density,
op-eds resemble spoken language more than editorials. Secondly, through an analysis of keywords and headlines, differences are observed across the two types of newspapers, quality and popular, and between American and British papers. Lastly, the phraseology of the two discourse types is examined through comparing clusters of 2, 3, or 4 words in the subcorpora
The making of the CorDis corpus: Compilation and markup

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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
