The Institute of Scientific Information has edited an index to evaluate the diffusion of scientific articles. It is based on the fact that the more an article is cited as a reference in other articles, the more it is considered to be important, and the higher the coefficient attributed to the journal in which it was originally published. Several methods of evaluation have been proposed, the two main ones being the impact and citation half-life. The impact factor takes into account the average number of times which a journal is mentioned for recent articles published in a given year. The citation half-life gives an insight into the longeivity of the articles of a journal by the number of citations received. This index is an attempt to quantify the notoriety of scientific journals for all scientific medical specialties. Each year, the institute for Scientific Information publishes a classification of the journals of each medical specialty.
科学信息研究所编辑了一个索引来评估科学文章的传播情况。其依据是，一篇文章在其他文章中被引用作为参考文献的次数越多，就越被认为重要，其最初发表所在期刊的系数也就越高。已经提出了几种评估方法，其中两种主要方法是影响因子和被引半衰期。影响因子考虑了某一期刊在给定年份发表的近期文章被提及的平均次数。被引半衰期通过期刊文章获得的引用次数来洞察其文章的持久影响力。这个索引试图量化所有医学专业领域中科学期刊的知名度。每年，科学信息研究所都会发布各医学专业期刊的排名。
