This paper takes the cue from the case of a retracted paper, cited both by the retraction notice and by an article published later in the same journal. This led to analysis and discussion on the skewness of citations in the journal Sustainability and within Multidisciplinary Digital Publishing Institute (MDPI) journals, particularly investigating self‐citations at journal and publisher levels. I analysed articles published by Sustainability in 2015 and found that self‐citations are higher than expected under a uniform probability distribution. Self‐citations in this journal make a 36% difference to the journal's impact factor. This research raises the question of what citation patterns can be expected as normal, and where the boundary between normal and anomaly lies. I suggest the issue deserves further investigation because self‐citations have several implications, ranging from impact factors to visibility and influence of scientific journals. 相似文献

This study shows how a journal's influence can be calculated by using citations obtained from Google Scholar and other methods even though the journal is not covered by any citation databases. Influence is measured in terms of foreign contributions, ‘equivalent’ immediacy scores of recent articles, and the calculation of citations and ‘equivalent’ impact factor. A total of 580 articles published in the Medical Journal of Malaysia (MJM) between 2004 and 2008 served as the sample. Very few foreign authors contributed to MJM (12.5%), implying its low regional acceptance as a channel for research communication. Immediacy scores for each year indicate citations were received by recently published articles. A total of 1,164 citations were received by 446 of the 580 articles and the main citing sources were journals (1,083) with reasonable h index and impact factor. Yearly impact scores ranged between 0.367 and 0.616. Higher impact factor scores were obtained by older articles. 相似文献

Choosing a publication venue for an academic paper is a crucial step in the research process. However, in many cases, decisions are based solely on the experience of researchers, which often leads to suboptimal results. Although there exist venue recommender systems for academic papers, they recommend venues where the paper is expected to be published. In this study, we aim to recommend publication venues from a different perspective. We estimate the number of citations a paper will receive if the paper is published in each venue and recommend the venue where the paper has the most potential impact. However, there are two challenges to this task. First, a paper is published in only one venue, and thus, we cannot observe the number of citations the paper would receive if the paper were published in another venue. Secondly, the contents of a paper and the publication venue are not statistically independent; that is, there exist selection biases in choosing publication venues. In this paper, we formulate the venue recommendation problem as a treatment effect estimation problem. We use a bias correction method to estimate the potential impact of choosing a publication venue effectively and to recommend venues based on the potential impact of papers in each venue. We highlight the effectiveness of our method using paper data from computer science conferences. 相似文献

To explore the citation evolution of papers published in the same year but different month, we selected papers from a discipline (physical geography), a subject (diabetes: endocrine and metabolism) and a journal (Journal of Biological Chemistry) published in 2005 as research objects. These papers were divided into six groups according to the difference in publication month, and we analyzed citations to these papers for the 9 years after publication. The results showed that within 5 years after papers from physical geography were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); after that, the differences were not statistically significant. Within 5 years after papers from diabetes (endocrine and metabolism) were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Within 7 years after papers from the Journal of Biological Chemistry were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Citations of papers followed the same pattern irrespective of discipline, subject or journal: citations of papers published in the same year but different month were obviously different in the first few publishing years, but as time went on, only the difference in publication month in a calendar year did not affect the papers' longer‐term citation. 相似文献

The Web impact of open access social science research 总被引：1，自引：0，他引：1
For a long time, Institute for Scientific Information (ISI) journal citations have been widely used for research performance monitoring of the sciences. For the social sciences, however, the Social Sciences Citation Index® (SSCI®) can sometimes be insufficient. Broader types of publications (e.g., books and non-ISI journals) and informal scholarly indicators may also be needed. This article investigates whether the Web can help to fill this gap. The authors analyzed 1530 citations from Google™ to 492 research articles from 44 open access social science journals. The articles were published in 2001 in the fields of education, psychology, sociology, and economics. About 19% of the Web citations represented formal impact equivalent to journal citations, and 11% were more informal indicators of impact. The average was about 3 formal and 2 informal impact citations per article. Although the proportions of formal and informal online impact were similar in sociology, psychology, and education, economics showed six times more formal impact than informal impact. The results suggest that new types of citation information and informal scholarly indictors could be extracted from the Web for the social sciences. Since these form only a small proportion of the Web citations, however, Web citation counts should first be processed to remove irrelevant citations. This can be a time-consuming process unless automated. 相似文献

The history and development of the Science Citation Index (SCI) is an example of the power of users in defining and influencing the development of a new technology. The SCI was developed as a tool for the historian of science for the purpose of tracing the history of ideas, but it was appropriated by users for purposes for which it was unintended – as a tool for evaluating the literature, individuals, institutions, and countries. The development of a citation tool gave rise to a debate over what is actually measured by citations. The citation‐as‐reward camp views citations as indicators of quality and impact, whereas the citation‐as‐persuasion camp views citations as no more than rhetorical devices. While neither view can fully explain how authors use citations, citation‐as‐reward prevails as the dominant interpretation. 相似文献

The promotion of scholarly journal articles to journalists and bloggers via the dissemination of press releases generates a positive impact on the number of citations that publicized journal articles receive. Research by John Wiley & Sons, Inc. shows that article‐level publicity efforts and media coverage boosts downloads by an average of 1.8 times and were found to increase citations by as much as 2.0–2.2 times in the articles analyzed in this study. We evaluated scholarly journal articles published in nearly 100 Wiley journals, which were also covered in 296 press releases. The results in this case study suggest a need for greater investment in media support for scholarly journals publishing research that sparks interest to a broad news audience, as it could increase citations. 相似文献

OBJECTIVE: To conduct a bibliometric evaluation of the Journal of Ayub Medical College (JAMC), Abbottabad, Pakistan. Methods: The data of articles, citations and authors of JAMC from 1997 to 2006 were collected and analysed in terms of bibliometric parameters. RESULTS: The number of articles published per year ranges between 27 and 97; most of the articles (47.2%) have 11-20 citations. Three-author contributions ranked the highest (134; 23.43%); the most prolific authors contributed seven articles; 295 (51.57%) of the authors are geographically affiliated to the North West Frontier Province (NWFP), Pakistan; the most popular subject is Internal Medicine; journal self-cited references are 43; 7769 (77.94%) of the citations were from foreign journals; the most productive institution is Ayub Medical College, Abbottabad, Pakistan. CONCLUSION: The number of papers published in JAMC per issue has been increasing over the last 10 years, and the core region is NWFP, Pakistan. Original articles are the main type of papers for this journal. The publication is open for all fields of medical sciences. 相似文献

The relationship between researchers’ publishing and citing behaviours has received little examination despite its potential importance in scholarly communication, particularly at an international level. To remedy this we studied documents and their references indexed in Thomson Reuters's Web of Science (WoS) in the period 2000–2009 to compare journal publishing behaviours against journal citing behaviours across the world. The results reveal that most publications in, and citations to, all five quality based strata of journals examined come from scientifically and economically advanced countries. Nevertheless, in proportion to their total number of citations given to WoS journals, it seems that less developed countries cite high-quality journals at the same rate as developed countries and so the poorer publishing of less developed countries does not seem to be due to a lack of access to top journals. Moreover, examining the publishing and citing trends of countries revealed a decreasing rate of high-income and Scientifically Advanced Countries (SACs) publications in, and citations to, all quality ranges of journals in comparison to the increasing rate of publications and citations of other groups. Finally, research cooperation between developed and less developed countries seems to positively influence the publishing behaviour of the latter as their publications co-authored with developed countries were published more often in top journals. 相似文献

We study the effects of an article featured on the cover of the journal Nature on citations to all articles published by its authors. Based on 30 years of bibliometric data, we find that cover articles are cited significantly more than non-cover articles, with this difference being long-lasting. However, when considering all articles (past and future) by Nature authors, we find that the publication of a cover article causes citations to previous articles by its authors to decline relative to citations to articles by non-cover authors. 相似文献

By examining citations in international relations journal articles published between 2000 and 2005, this study reveals that international relations scholars more heavily rely on books rather than on journals. Less than 2% of the citations are from electronic resources. Materials in foreign languages are utilized insignificantly, with English language citations dominating the research literature. The analysis of subject scatter details the main disciplines that are associated with international relations research. Qualitative scholars cite a higher proportion of monographic literature, while quantitative scholars display a higher journal citation rate. 相似文献
