Estudos de Análise de Cocitação de Autores: uma abordagem teórico-metodológica para a compreensão de um domínio

This piece of research aims at analyzing the absolute and relative co-citation indicators, especially Salton’s Cosine and comparing the contribution of these indicators to the understanding of a domain, applying them to the universe of "Metric Studies" at the BRAPCI base. It also aims at presenting the co-citation network generated from the absolute frequencies and highlighting the groupings of co-cited authors, depending on the relative values, integrating and explaining the information from the two indexes. The domain analysis, by means of its 11 approaches, including “Bibliometric Studies”, focuses on the science characterization and evaluation, in that it allows us to identify and to analyze the conditions under which the scientific knowledge is constructed and socialized. In these studies, the contribution of citation and co-citation analysis is highlighted. Of the total of 147 articles retrieved at BRAPCI base, the authors cited in at least 11 articles, in a total of 38 researchers, were selected. The 38 x 38 symmetric matrix with the absolute frequencies of co-citation and the matrix with the relative values of Salton’s Cosine were generated. The co-citation network with absolute frequency values were constructed, through Ucinet software. Cluster analysis of data with relative values wer performed, using the SPSS software. Significant differences between the absolute and relative indexes, with some high absolute values of co-citation were observed; when considered in relation to the presence of each author, their significance is decreased. As to the generated network, seven groups were determined, in which only one is established for close themes and comes from co-citations in the original sense of the term. Five groups present closeness in absolute and relative indicators. It can be concluded about the importance of the studies of authors' co-citation analysis, which associate the two indexes, absolute and relative, in order to visualize and understand the underlying structures of a scientific domain.

Visibilidade dos pesquisadores no periódico Scientometrics a partir da perspectiva brasileira: um estudo de cocitação

This research aims at verifying the authors who have given basis to the brazilian researches internationally inserted in the area of Bibliometrics and Scientometrics through the analysis of citation and co-citation of the brazilian articles published in the journal Scientometrics. We used the Scopus data base, with the terms Scientometrics in source title and Brasil or Brazil in affiliation country. We found 53 articles, with 741 references and 19 authors cited 3 or more times. In general, the researchers come from the biologic and health areas. Using the Ucinet software, we build the co-citation network and calculated its indicators. We calculated the co-citation normalized index. The density and average of normalized degree centrality were 65,5%. We concluded the research highlighting the significant presence of brazilians (32%) and the dialogicity occurring between cited Brazilians and foreigners within a balance, where brazilians already dialog with renowned international researchers of the Bibliometrics and Scientometrics area.

Visibilidade dos pesquisadores no GT7 da ANCIB: um estudo de cocitações

This research aims at analyzing the researchers with major insertion and impact within the GT7 ENANCIB community, through an analysis study of citation and co-citation from 2003 to 2010. We propose to highlight the researchers cited in a greater number of papers, as well as the number of citations received. Also, to describe the co-citation network intending to analyze the interlocution network built by the writers towards the cited ones and calculate the indicators of density and centrality of the network. As for the theoretical-methodological basis, we used the Domain Analysis (D.A.), seen as the reflexion of a discourse community. Among the 11 approaches about D.A, the bibliometric studies stand out. Data from the 124 researches presented in the period of this study showed 1446 cited researches for a total of 2307 citations. From the total number of cited researchers in a greater number of papers, 33 were considered authors of major impact and visibility, being cited in at least 8 papers, thus getting at least 8 citations. The software Ucinet was used to map and visualize the net of interlocution established by the citing papers. As for the results, we could notice that, from the total of 33 researchers, 23 are Brazilian, 20 take part in Post-Graduation Programs and 11 are granted CNPq scholarships of productivity. Furthermore, we highlighted the most cited themes and analyzed the relationship involving the number of citations according to the number of papers in which the researcher was cited and the number of researches cited from each researcher. Regarding the network structure, we could observe that the authors form a single component, indicating that the group of researchers co-cited reveals proximity and theoretical, conceptual and methodological articulations. We concluded that the citing community adopts ordinary theoretical schools; moreover, we might characterize the core of the known researchers as a foundation for the knowledge of the GT7 theme.

El área de gestión de la información y del conocimiento como frente de investigación en la Ciencia de la Información brasileña: análisis de la producción científica en el período 2000-2009

The management of information and knowledge has been one of the areas of expertise of the fastest growing Brazilian information science. The purpose of this work is to observe how this research front structure from the point of view of the subjects that compose and intellectual frameworks which supports. For this we have analyzed the content of scientific production published in four majo r national journals of the discipline: Ciência da Informação, DataGramaZero, Perspectivas em Ciência da Informação and Transinformação over 2000-2009. The methodology is based on co-occurrence analysis of keywords of articles and co-citation analysis of authors. For the representation and interpretation of the results are used to social network analysis (SNA). We conclude that both information management and knowledge management are closely linked areas within topics including approaches but no consensus answer from the point of view of intellectual frameworks referenced.

A construção do conhecimento sobre governança corporativa: uma análise bibliométrica

Presents a survey of scientific production about the subject corporate governance, using the Bibliometric analysis of theses and dissertations collected in the digital libraries of the Sao Paulo State University (Unesp), Campinas State University (UNICAMP) and University of Sao Paulo (USP). Through the data collected were identified, based on Bibliometric indicators, the origin of authors, the authors more cited, the thematic area of authors, and the construction of co-citation network.

Análise de cocitação de autores: um estudo teórico-metodológico dos indicadores de proximidade, aplicados ao GT7 da ANCIB

Of a theoretical-methodological nature, this research aims at analyzing the absolute and relative proximity indicators – Salton’s cosine and Jaccard’s index –, for authors’ co-citation analysis (ACA). It also aims at comparing the contribution of these three indicators to the understanding of a domain. Methodologically, it deepens the theoretical studies that motivate authors’ co-citation analysis (ACA) and the proximity indicators, and presents the studies of the normalized index of Salton’ cosine (SC) and Jaccard’s index (JI). It applies ACA to the GT7 of ANCIB, in the Information Science field, from 2007 to 2011.

Análise da presença e articulação teórica da Catalogação de Assunto na literatura científica da International Society for Knowledge Organization ISKO: uma análise de domínio

Subject Cataloging is one of the processes of subject approach to information, beside indexing and subject analysis. In this sense, this research is a part of a broader project which analyses ISKO as an academic space that promotes a dialogical dimension among those theoretical questions. In this sense, it aims to analyze the presence of subject cataloguing in the discussions of knowledge organization as well as how the authors of such subject dialogue each other. Considering the questions, the full collection of ISKO and ISKO-Spain conference proceedings were analyzed in order to verify how present were subject cataloguing matters in those collections. It was possible to identify a group of 36 articles (27 from International ISKO and 9 from ISKO – Spain) whose references were bibliometrically analyzed in terms of documentary forms, average life, language and citation analysis. The results showed that the major ISKO and ISKO-Spain literature on subject cataloguing is based on journal articles, mostly published in English, presenting a relatively young average life (14 years for ISKO and 10 for ISKO-Spain).

A pesquisa sobre o fazer pesquisa: uma análise de citação da literatura periódica em Ciência da Informação

Introduction: This paper considers that information science (IS) literature covers a diversity of thematics with low emphasis on researches about conducting research. The study analyzes the scientific production of authors who investigate about research methodology in the information science (IS) literature, and the references used to lay the foundation of the methodological issues regarding the area. It discusses the methodological and epistemological positions of the leading researchers highlighted as the most productive investigators on the subject in the country. Method: The research adopts the content analysis coupled with metric studies to contextualize the indicators related to productivity, to the types of authorship and citation analysis. The bibliographic coupling method is considered an analysis mode which analyzes concomitant citations. It develops a theoretical framework about the importance of scientific production analysis in different knowledge fields. The study investigates, from a theoretical perspective, the concepts about research methodology and the complementarity between methodology and epistemology in conducting research. Results: The results of the analysis showed that the production of the highlighted authors presents the methodology as a thematic focus to be applied to IS contexts, as well as a research object in the field. The prominent productivity of the authors is justified especially by deepening the meta studies about the ways to conduct research in IS. This study also identifies a trend to single-authored studies about the theme. Conclusions: The research considers that meta studies and applied and methodological studies are important to recognize a consistent theoretical and practical core in the IS area. Regarding the epistemological influences identified by the citation analysis, the study observes that the critical rationalist epistemology and the social and political epistemology are highlighted in the construction of the theoretical framework of the most productive authors.
