1 引言文献计量学模型可用于多种科学文献。在3个最通用的模型中,布拉德福定律(1934)用于统计期刊生产率(信息源是期刊),洛特卡定律(1926)用于统计科技生产率(信息源是作者),齐夫定律(1949)用于统计正文中词汇出现的频率。已做过的一些拟合优度试验表明,发表在学术刊物上的论文生产率的表示法,在学术研究论文的共同的研究者中,通常是采取共同的方式。普赖斯(Price)和比弗(Beaver 1966)使用摘要资料,以泊松分布推导出那些没有统计过
1 Introduction The bibliometric model can be used for a variety of scientific literature. Among the three most common models, Bradford’s Law (1934) was used to count journal productivity (information sources are journals), Lotka’s Law (1926) for statistical technology productivity (source is author) The law (1949) is used to count the frequency of appearance of words in the text. Some goodness-of-fit tests done have shown that the notion of paper productivity published in scholarly journals generally takes a common approach among co-researchers of scholarly research papers. Price and Beaver (1966) use summaries of data to derive Poisson distributions that are not statistically significant
