==Abstract==
Scopus 資料庫中 JIF 分布狀況的研究。並與ISI-1997的研究作比較。
所有的特定研究主題領域的JIF分佈，都與ISI-1997研究一樣，符合負對數法則(negative logarithmic law)，集中在少數重要期刊上；並未如 Egghe 所預測的，呈現 S形分佈。但Scopus-2006 的分佈趨勢線降得更陡且有更長的尾部：就像是冰山一樣。

== Content ==
For each journal, we calculated 
* the number of citable papers (Articles, Reviews, and Conference Papers published in 2003, 2004, or 2005), 
* the total number of citations received (made in 2006 to papers published in 2003, 2004, or 2005), 
* the number of subcitations (citations from journals of the same specific subject area) received (made in 2006 to papers published in 2003, 2004, or 2005), 
* the number of references (made in 2006 to papers published in 2003, 2004, or 2005). 

These data were used to calculate the following indices:
* 知識輸出率 Knowledge Export Ratio (%) (Wormell 1998) (%export): 
* 知識匯入率 Knowledge Import Ratio (%) (%import):
* 內部期刊影響指數 Internal Journal Impact Factor: similar to the JIF, but only taking into account the citations from that same Specific Subject Area (Subcitations).
* 外部期刊影響指數 External Journal Impact Factor: similar to the JIF, but only taking into account the citations not from that same Specific Subject Area.
