Abstract

  • 背景/動機:比較四項期刊引文指標: Journal Impact Factor, Eigenfactor(Article influence), SCImago Journal Rank, Scopus Trend Line
  • 假定:
  • 方法:兩兩比較各指數的相關性,六種可能比較組合:Spearman's rho.
  • 資料:
    • The number of journals that could be matched within each pair of indices ranged from 1,857 to 6,508.
  • 發現:四種指標高度相關
    • Paired ratings for all journals showed strong to very strong correlations, with Spearman’s rho values ranging from 0.61 to 0.89, all p\0.001. Identifiable errors were more common among scores for journals that had very discordant ranks on a pair of indices.
    • 某些不相關的個案,源於該索引的錯誤
