Quantitative analysis of Italian texts
Full text linkThe present book can be considered a continuation of two streams in textology initiated by different groups of scholars. The first group consisting of Italian scientists analyzed the 57 end-of-year speeches of 9 Italian presidents since 1949
to 2005 from very different points of view. The investigation resulted in the book edited by M.A. Cortelazzo and A. Tuzzi (2007) containing statistical vistas and political, social, linguistic and cultural matter. The second group, lead by I.-I. Popescu consisting of linguists and mathematicians, focused on general aspects associated with texts, namely text characterization, fixed points, vocabulary richness, thematic concentration, compactness, study of autosemantics, the impact of the position in sentence; this group also focused on the possibility of drawing conclusions from text to the morphology of language, etc. This investigation resulted in two books authored by I.-I. Popescu et al. (2009) and I.-I. Popescu, J. Mačutek and G. Altmann (2009). The present book is a further development of methods and fully concentrated on the end-of-year addresses of Italian presidents. Moreover, the updated version of the corpus includes 60 end-of-year speeches of 10 presidents since 1949 to 2008. The aim was to look at the highest floor of the linguistically perceived reality, namely the sets of word associations, compare these worlds and pursue a possible development in this thematically homogeneous corpus. The book includes chapters concerning the golden section, Zipf ́s law, parts-of-speech analysis and some issues concerning vocabulary richness,continuing the examinations resulting from earlier common publications
Zipf's laws in Italian texts
No full textThere are texts which do not conform to the classical Zipf’s law, but even if it holds, some questions remain open. In order to test the validity of Zipf’s law we analysed a corpus
composed of the End of Year addresses delivered by ten presidents of the Italian Republic in the period 1949–2008. The results show that Zipf’s law is an adequate model and that
the corpus has a unique style, even if the texts were compiled by at least two persons. The analyses allow us to find a position for each president on the synthetism/analytism scale.
Presidents Pertini and Scalfaro show the best well-defined individual characteristic features
Parts-of-speech diversification in Italian texts
No full textIn the present article some characteristics of the rank-frequency distribution of parts-ofspeech in the end-of-year speeches of Italian presidents are scrutinized. The result is compared with some other languages
The golden section in texts
No full textThe golden section is a well known phenomenon observed in nature, arts and sciences, documented with an enormous number of publications. Here we shall try to show its presence in the rank-frequency distribution of words in natural texts with emphasis on Italian using the End-of-Year Speeches of the Presidents of the Italian Republic
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
Analysis of Italian word classes
No full textIn the article, the development and the stabilization of the occurrence of parts of speech in Italian texts are analyzed. The data were won from opera librettos since 1607 and from all end-of-year speeches of Italian presidents (1949-2008). The results display both developmental, text-sort and content-dependent differences. In order to obtain a more complete image, the analysis should be applied to many other Italian texts
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
