Bibliometric
 应用数学与统计方法至书或其它形式的
文字传播。是一种测量的技术。
(Pritchard, 1969)
 以量化方式处理记录论述的属性及其相
关行为。(Fairthor, 1969)
Bibliometric
 以数量分析与统计方法对文献做分布与
特性的探讨。

Bibliometric Laws
 Lotka’s Law
 Bradford’s Law
 Zipf’s Law
Lotka’s Law
 Lotka, Alfred James (1880 - 1949), USA
 The number of authors making n
contributions is about 1/na of those making
one contribution, where a is often nearly 2.
 Lotka, A.J. (1926), The frequency
distribution of scientific productivity.
Journal of the Washington Academy of
Science, 16 (12), 317-323.
Bradford’s Law
 Samuel Clements Bradford (1878-1948)
 Journals in a field can be divided into three parts,
each with about one-third of all articles: 1) a core
of a few journals, 2) a second zone, with more
journals, and 3) a third zone, with the bulk of
journals. The number of journals is 1:n:n2.
 Bradford, S.C. (1934), Sources of information on
specific subjects. British Journal of Engineering,
137 (3550), 85-86.
Zipf’s Law
 George Kingsley Zipf (1902-1950)
 The probability of occurrence of words or
other items starts high and tapers off.
Thus, a few occur very often while many
others occur rarely.
 Pn 1/na, where Pn is the frequency of
occurrence of the nth ranked item and a is
close to 1.
Zipf’s Law
rf = C
where r is the rank of a word;
f is the frequency of occurrence of the word;
C is a constant that depends on the text being
analyzed.
Zipf’s Law
 Zipf, G.K. (1945), Some psychological
determinants of the structure of
publications. American Journal of
Psychology, 58 (4), 425-442.

JCR评估过程
 ISI每年审查的期刊约有2,000种
 10%到20%的期刊会被收录
 已被收录的期刊也被追踪考核，以确定
其仍然维持高质量水平。
 ISI评估小组具有其所负责领域的相关教
育背景，及信息科学方面的经验素养，
必要时ISI的顾问团也参与评估。
JCR评估考虑因素
 期刊的基本出版标准（Basic Journal
Standards）
 编辑内容（Editorial Content）
 国际性（Internationality）
 引用文献分析（Citation Analysis）
JCR-期刊评鉴工具





