English abstract

This paper investigates the trends of Impact Factors and self-citation rates of journals indexed in the JCR by two neighbouring countries Iran and Turkey for a period of five years (2000- 2005). All data extracted from the Journal Citation Reports – Science Edition (2000-2005). The study showed that the portion of Turkish journals entering data to the JCR data bank is two times higher than the portion of Iranian journals. From a total number of 6,088 journals in the JCR in 2005, 3 (0.05%) were published in Iran and the same number of journals published in Turkey. The 6,088 journals in the JCR produced 847,114 articles, 159 (0.02%) appeared in the Iranian journals and 352 (0.04%) in the Turkish journals. Of the 22,353,992 citations in 2005, 214 (0.001%) came from Iranian journals and 911 (0.004%) came from Turkish journals. The self-citation tendency by Iranian journals has increased dramatically throughout the period of study, it reached from 8% self-citation rate in 2000 to 18% in 2005, an increase of 2.25 times, whereas the self-citation rate by Turkish journals showed a negative trend, its self-citation rate fell from 22% in 2002 to 15% in 2005. The Impact Factors of Turkish journals showed faster growth than the Iranian journals, the mean value of Impact Factor for Turkish journals in 2000 was 0.49 under than the mean value of Impact Factor for Iranian journals, but in 2005 the mean value of Impact Factor for Turkish journals stayed 0.14 higher than the mean value of Impact Factor for Iranian journals.

Turkish abstract

Bu makale, iki komşu ülke, İran ve Türkiye tarafından 5 yıl (2000-2005) içinde üretilen yayınlardan JCR’de dizinlenen dergilerdeki kendine atıfları ve etki faktöründeki eğilimleri incelemektedir. Bütün veriler JCR-Science Edition (2000-2005)’den alınmıştır. Çalışma, Türk dergilerinin İran dergilerinden iki kat fazla miktarda JCR’ye girdiğini göstermektedir. 2005 yılında JCR’de yer alan toplam 6.088 dergiden yalnızca üçer (%0,05) dergi İran’da ve Türkiye’de yayınlanmaktadır. JCR’deki 6.088 dergide bulunan 847.114 makaleden, 159’u (%0,02) İran, 352’si (%0,04) Türkiye adreslidir. Aynı dönemdeki 2.353.992 atıfın, 214’ü (%0,001) İran, 911’i (%0,004) Türk dergilerinde görülmektedir. İran dergilerinde kendine atıf eğiliminin dramatik biçimde artarak, 2000’de %8 olan kendine atıf oranının 2005 yılında %18’e yükseldiği; Türk dergilerinde ise 2002 yılında %22 olan oranın 2005’de %15’e düştüğü görülmektedir. Türk dergilerinin etki faktörleri, İran dergilerinden daha hızlı bir gelişme göstermiştir. Türk dergileri 2000’de 0,49 etki faktörüyle, İran dergilerinin altında yer alırken, 2005’de bu oran 0,14 kadar artarak, İran dergilerinin etki faktöründen daha yükseğe çıkmıştır.
