Abstract

Acta Microbiologica et Immunologica Hungarica (AMIH) is a quarterly publication, which was founded by the Hungarian Academy of Sciences (MTA), devoted to publishing manuscripts in all fields of medical microbiology, immunology and studies regarding the human microbiome. Bibliometrics is an area of science, which is concerned with the qualitative and quantitative assessment of research, that is often used to evaluate the impact of journals, institutions, study groups or individual scientists. The aim of this study is present a general overview of AMIH from 2005 to 2018 using bibliometric indicators. The data analyzed in this study, dating between 2005 and 2018 was extracted from the Scopus database. The information was exported in RIS file format to the Harzing’s Publish or Perish 6.44 software for data analysis. In addition, VOSviewer 1.6.9 software was used to generate the collaboration and word co-occurrence networks. The total number of documents published in AMIH during the study period (2005-2018) was 464, and these articles were cited 2384 times overall, averaging 5.14 citations per each paper. The average ratio of collaborative papers was 18.13%. The average ratio of self-citations for AMIH was around 10%, which could be considered a good result compared to some international publications. Acta Microbiologica et Immunologica Hungarica manages to reach a wide audience of the Hungarian scientific community of researchers interested in its content. The submission of additional articles from a wider audience would strengthen the international reach and scientific impact of AMIH.


1. Introduction

Acta Microbiologica et Immunologica Hungarica (AMIH) is a quarterly publication, which was founded by the Hungarian Academy of Sciences (MTA). The journal is devoted to publishing manuscripts in all fields of medical microbiology, immunology and studies regarding the human microbiome, looking for submissions from both Hungarian study groups and an international audience of scientists [1]. Additionally, supplement issues related to the conferences organized by the Hungarian Society of Microbiology (MMT) are also published. Bibliometrics is a tool for quantification which uses scientific communication between scholars as the basis for analysis [2]. It is concerned with the qualitative and quantitative assessment of research, that is often used for the evaluation of various journals, research institutions, universities, study groups or individual scientists [3,4]. The bibliometric analysis of a journal may be important for several reasons. The authors mainly study commonly known bibliometric parameters (such as impact factor (IF), Hirsch-index (h-index), number of publications per year etc.) before the potential submission of manuscripts. In addition, university libraries also often evaluate the abovementioned characteristics before including journals in their collection [5,6]. Another important landmark for any journal is the inclusion to major databases and indexing services (such as PubMed/MEDLINE, Web of Science, Scopus), which will help to increase the reputation of a journal, allowing for a wider audience. The present study aims to give a bibliometric overview of AMIH in a 14-year period (2005-2018), since the journal was listed by major international content indexing services.

2. Materials and Methods

The bibliometric data analyzed in this study, dating between 2005 and 2018 was extracted from the Scopus database on the 5th of January 2019. The information was exported in RIS (Research Information Systems, Incorporated) file format to the Harzing’s Publish or Perish 6.44 software for data analysis [7,8]. In addition, VOSviewer 1.6.9 software was used to generate the collaboration and word co-occurrence networks from the recovered data [9].

3. Results and Discussion

The total number of documents published in AMIH during the study period (2005-2018) was 464 (Table 1.) The most frequently published document type indexed by Scopus was „original article” (n=420, 90.52%), followed by "review” (n=32, 6.89%; first occurrence in 2005), „letter” (n=5, 1.08%; first occurrence in 2010) and „short survey” (n=2, 0.43%; first occurrence in 2005). Additionally, there were two papers classified as an „editorial” (in 2009 and 2010) and three as an „erratum” (2008-2010), respectively. The average amount of authors per paper remained relatively consistent throughout the years (4.06-5.13; Table 1).

Table 1: Articles published in international collaboration in AMIH between 2005-2018.

Regarding the impact of papers in AMIH, articles published between 2005 and 2018 were cited 2384 times overall, averaging 5.14 citations per each paper (Table 1.). The average ratio of self-citations was 9,97±6,61% (1.72-18.28%; lowest in 2013, highest in 2015). The papers with high amount of citations (defined as 20 or more cites, n=16) correspond to 26.43% of total citations (52.50 citations per year, 206.57 cites/author) for AMIH (articles listed in Table 2.). The journal received its first IF in 2010 (Table 3.) and it reached its highest value for the 2016/17 citation period (1.107).

The journal is indexed in two subject categories, namely Medicine (miscellaneous) and Immunology and microbiology (miscellaneous); the journal has been categorized in the Q2-Q3 rank in the former and Q3-Q4 in the latter category, based on the international impact of the papers published in AMIH (Table 4.). The ratio of collaborative publications (defined as articles with authors from more than one country) in AMIH was also assessed as this is another relevant factor by which the reach of journals may be assessed. Presented in Table 5., the average ratio of collaborative papers was 18.13%.

In order to establish the network of collaborators and the profile of the journal in more depth, the authors and the keywords present in the titles and abstracts of the published documents were analyzed by VOSviewer to generate clusters and co-occurrence networks. Together with the connecting lines, the colors in Figures 1 and 3 indicate the relationship of the authors and keywords, while in Figures 2 and 4, the shade of color indicates the temporal nature of relationships. Out of 1639 authors, 272 met the threshold to become “nodes” in the generated network, while 149 could be included in the network (i.e., had at least one co-authored paper with another author qualifying to be a “node”) to generate clusters of association (Figure 1 and Figure 2). In addition, 6090 keywords were identified by VOSviewer, from which 1497 met the threshold to become “nodes” and 178 was enrolled in the generation of the co-occurrence network (Figure 3 and Figure 4). The keywords “article” and “English article” were excluded for methodological reasons. Based on these results, the topics covered by published articles reflected on the changing trends in microbiological sciences in the respective study period [26].

4. Conclusions

This study presents a qualitative and quantitative bibliometric analysis of the leading trends that occurred in Acta Microbiologica et Immunologica Hungarica between 2005 and 2018, using the Scopus database for the collection of bibliographic information and specialized software for data analysis. The average ratio of self-citations for AMIH was around 10%, which could be considered a good result compared to some international publications, and especially if compared to other journals based in Hungary. To assess AMIH from a different perspective, our research also presents keyword co-occurrence and collaboration networks of the journal. Acta Microbiologica et Immunologica Hungarica manages to reach a wide audience of the Hungarian scientific community of researchers interested in its content, being the main national publication for submissions related to the scope (medical microbiology, immunology, microbiomestudies etc.) of this journal. Additionally, an evolution of the research topics covered by the published papers could be observed, based on the cluster analysis performed. As an added value, AMIH possesses a considerable impact factor, which may further encourage researchers to submit their work in this journal, as there is increasing pressure to publish in international journals with (preferably high) impact factors, because this has become a pre-requisite for the awarding of doctoral (PhD) degrees, in addition to the successful application for research grants. The submission of additional articles from a wider audience would strengthen the international reach and scientific impact of AMIH.
