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):
