Toward the more effective identification of journals with anomalous self-citation. https://doi.org/10.1087/095315108X378712. We agree with a possible criticism that the group of researchers analysed here may not be wholly representative of their field since they are generally likely to be more experienced in building a substantial portfolio of well-cited publications. The Thomas theorem and the Matthew effect. 2019; Kacem et al. Finally, attention must be paid to the presence of co-authors on publications that have self-citation rates significantly above expectations. ), 21st International conference on science and technology indicators (STI 2016), pp. A high rate of self-referencing may reflect research in a specialty area or convey a pattern of a cohesive and sustained research program (Cooke and Donaldson 2014). So the FWCI would be 23 / 18 = 1.28. Journal of Legal and Political Sociology, 1:115126 (Reprinted in: Merton, R. K. (1973). A percentile defines a fraction or subset of papers in a research field that received a minimum number of citations. Between 2000 and 2015, the proportion of citations that went to this elite group grew from 14% to 21%. https://doi.org/10.1007/BF02019738. "[61][62], According to Mario Biagioli: "All metrics of scientific evaluation are bound to be abused. One of the most basic citation metrics is how often an article was cited in other articles, books, or other sources (such as theses). These rates of self-citation are evidently much lower than those of self-referencing, as expected for Highly Cited Researchers because their broad peer influence attracts many cites from others (van Raan 2008), and they are relatively more variable between fields compared to self-referencing. Journal of Informetrics,14(2), 100990. https://doi.org/10.1016/j.joi.2019.100990. 2: r=0.55, N=240 researchers, P<0.001) and for the ESI field of Engineering (r=0.59, N=225 researchers, P<0.001). Wilsdon, J., Allen, E., Belfiore, E., Campbell, P., Curry, S., Hill, S., et al. Another potential reason for the spike in Covid-19 citations is the exhibited capacity of the virus to mutate rapidly. For the 2019 Highly Cited Researchers analysis, the papers included in the preliminary data development were those published and cited during 20082018. The article's average annual citation rate would be (10 + 5 + 12) / 3 = 9 citations per year. However, a recent meta-analysis showed that the advantage of open-access is debatable with many studies showing no difference in citation rates andquality and heterogeneity concerns posing challenges for generalization [22]. https://doi.org/10.1007/BF02458493.
