Um método para analisar a temática de periódicos voltados para a saúde coletiva / A method to analyze the thematic of journals focusing on public health / Un método para analizar la temática de revistas dirigidas a la salud colectiva

Este artigo discute uma proposta metodológica de investigação da temática da produção científica no campo da saúde coletiva, com o apoio da teoria de redes, tomando como referência de aplicação os artigos publicados no periódico Cadernos de Saúde Pública em 2011. A proposta inclui a construção e a análise de redes semânticas de títulos de artigos e uma comparação com redes semânticas de grupos de coautores. No experimento, montou-se uma rede de dois modos: com títulos (269) e autores (858); em seguida, foram projetadas, separadamente, as redes de autor e de título. Foram construídas e caracterizadas redes semânticas de títulos. Uma sub-rede de coautores foi escolhida e a correspondente rede de títulos comparada com a rede total. A proposta aponta alternativas que podem ser exploradas no trato da aplicação da análise de redes sociais na saúde e, em particular, na saúde coletiva. Índices da análise de redes são estendidos às redes semânticas de títulos e devidamente interpretados. Os resultados para a produção e período escolhidos mostram que a rede de dois modos e suas projeções são fragmentadas, com muitos componentes; apontam também para a influência de grupos de coautores na temática geral do periódico em questão. Na análise da rede dos títulos, os temas que se destacaram são resultado de estudos coerentes com as metas prioritárias de pesquisa do Ministério da Saúde.

This paper discusses a methodological proposal of research related to scientific production focusing on public health, with the support of network theory, taking as reference the application of articles published in the journal titled Cadernos de Saúde Pública (Reports in public health) in 2011. The proposal includes the construction and analysis of semantic networks based on titles of scientific papers and a comparison with semantic networks of co-authors groups. In the experiment, it was set up a two-mode network with 269 titles and 858 authors; then the co-authorship network and the title network were separately built. Semantic networks based on titles of scientific papers were built and characterized. A co-authorship subnetwork waschosen and the corresponding title network was compared to the original network. The proposal points out alternatives that can be explored in the application of social networks analysis to health and, in particular,to public health. Network analysis indexes are extended to semantic networks based on titles of scientific articles and appropriately interpreted. The results for selected production and period show that the two modenetwork and its projections are fragmented, with many components; the results also point to the influence of groups of co-authors on the general theme of the analysed journal. In the analysis of semantic networks based on titles of scientific papers, the most prominent themes are the result of coherent studies toward the priority goals of research of Brazilian Ministry of Health.

Co-authorship networks in regional health informatization research community in China / 中华医学科研管理杂志

Objective To reveal the status quo and emerging issues of co-authorship in regional health informatization research community in China.Methods The terms or keywords describing and covering regional health informatization were used to search the most relevant literatures about the subject in CNKI,Wanfang database and PubMed.Software tools were used to extract bibliographic,Social network analysis (SNA);co-authorship,and co-word analysis were used in this study.Results ①11,482 articles with 16,449 authors in the period of 1984-2013 were found.Each publication has an average of 1.43 authors,and each author has 0.70 publications.The number of coauthored literature was 7741 (67.42 ％).Both production and collaboration have been growing steadily.② Coauthored knowledge network was build which composed by 150 high-yielding Authors.The largest component comprises 43 authors(28％,43/156).The intermediate centrality of 57 authors were above 0.③ 230 2-plexes were found,and 65 2-plexes scale was 4 and over;and there was overlap among them.There were extensive cooperation between the military institutions,a large number of regional health information technology research talent were found in army research institutes..Cohesive subgroups density showed an E-I index=-0.901,which indicated that factionalism was comparatively weaker in this field,and the relationship tended to occur among subgroups.④ Cooperative network was established between the provinces and municipalities.Beijing,Guangdong,Jiangsu,Hubei were the core area.⑤ The average distance between the author=3.155,and it consistent with the small-world characteristics.⑥ The largest component of the network research can be summarized into three categories:HIS-related research,electronic medical records related research,and regional health informatization related research.Conclusions Although such collaboration is growing steadily,the collaboration behavior about regional health informatization study needs to be enhanced.Policy makers and researchers can refer to the relevant information and promote cooperation,improve the capacity of regional health information research and construction.

Correlation between co-authorship network parameters and bibliometric assessment parameters / 中华医学图书情报杂志

Articles, reviews and proceeding papers published from 2012 to 2015 in medical, chemical and physical journals with the highest IF were retrieved from 2014 JCR and analyzed using the BICOMB software to generate the co-occurrence matrix of authors and plot the map of co-authorship network in medical, chemical and physical fields using the UCINET software.The correlation between the parameters for assessing the importance of co-au-thorship network nodes ( degree centrality, betweenness centrality, closeness centrality, eigenvector centrality) and biblimetric parameters of authors ( number of published papers, frequency of cited papers) was analyzed using the SPSS, which showed that degree centrality, betweenness centrality, and eigenvector centrality were positively corre-lated with the number of published papers and the frequency of cited papers whereas betweenness centrality was negatively correlated the number of published papers and the frequency of cited papers.Betweenness centrality was more significantly correlated with the number of published papers whereas degree centrality was more significantly correlated with the frequency of cited papers.

Graphic database Neo4 J-based research and practice of co-authorship network / 中华医学图书情报杂志

Research of co-authorship network can reveal the scientific research collaboration network and can thus help us to have an understanding of it. Graphic database and Neo4J were described in detail due to the limitations of relationship database in processing the data of co-authorship network. Graphic database Neo4J-based research and practice of co-authorship network were analyzed with the Institutional Knowledge System of AMMS that we were involved in its construction as an example, and the advantages of Neo4J-based co-authorship network were summarized.

After the basic properties of literature-related citation network, co-authorship network and co-words network were analyzed and the advances in their application research were summarized in aspects of their construc-tion methods, size and research depth, it was pointed out that article similarity networks could be constructed using the article similarity algorithm, and their basic properties and features were analyzed.
