Une méthode de classification basée sur l'entropie
No full textVittorio Capecchi : Eine auf die Entropie beruhende Klassifizierungsmethode.
Das Problem der Klassifizierung von Individuen, die entsprechend ihren Antworten auf mehrere Entweder-oder-Fragen gekennzeichnet sind, ist von den Biologen verschieden gelöst worden. Der Verfasser analysiert diese Lösungen und zeigt, inwiefern sie für den Soziologen wertvoll sein konnen. Er untersucht nacheinander die Metboden, die auf die Aehnlichkeit der Antworttypen (similarité), auf die Verschiedenheit der Auslesekapazität der Fragen (sélectivité), bzw. auf diese beiden gleichzeitig in Betracht gezogenen Kriterien begrundet sind. Die fur die Selektivität vorgeschlagene Messmethode wertet Techniken aus, die aus der Theorie der Information hergeleitet sind. Der Verfasser führt ein zahlemmässiges Beispiel der letzten Klassifizierungsmethode an und vergleicht seine Resultate mit solchen, die durch die Analyse der latenten Struktur hätten gewonnen werden konnen.Виктор Капечи : Метод классификации, обоснованный на энтропии.
Автор анализирует различные выводы, сделанные биологами по поводу классификации индивидумов, при помощи целой серии ответов на раздвоенные вопросы и указывает на их пользу для социолога. Он исследует последовательно методы классификации, основанные на сходстве типов ответа, на сходстве двух критериев, взятых одновременно. Мероприятия предлагаемого выбора употребляют технику, происходящую из теории информации. Автор представляет числовой пример, иллюстрируя последний метод и сопоставляет, полученную классификацию с той, которая получается после анализа неявной структуры.Vittorio Capecchi : A method of classification based on enthropy.
The author analyses the various solutions biologists have found to the problem of the classification of individuals characterised by a series of answers to dichotomic questions, and points out their value for the sociologist. He examines successively the methods of classifications based on the similarity of types of answers, on the differential selectivity of the questions and on the two criteria considered simultaneously. The proposed measure of selectivity employs technics derived from the information theory. The author gives numerical examples illustrating the last method, and compares the classification obtained with that resulting from the analysis of latent structures.Vittorio Capecchi : Un metodo de clasificación basado en la entropía.

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
