论文摘要
共同引用的测量可以揭示代表现有思想新颖组合的概念在多大程度上发展为专业的。共同引证的强度由其频率表示，随着时间的流逝会积聚。有趣的是，是否可以确定与共同引文强度相关的基本特征。我们使用近端引文网络作为给定的文章（x，y）来计算theta，这是对X和y之间共同引用的可能性的先验估计，在其第一次共同引用之前，theta的较低值反映了对这些文章的成对的较低的值，这些文章的可能性降低了。我们观察到共同引文频率是幂律和对数正态分布的综合，并且非常高的共同引文频率更有可能由theta值低的对组成，这反映了新思想组合的影响。此外，我们注意到，共同引用对的两个成员之间直接引用的发生随着共同引用频率的增加。最后，我们确定了经常被共同引用的出版物的案例，这些案例在长期休眠后会累积引用。
Co-citation measurements can reveal the extent to which a concept representing a novel combination of existing ideas evolves towards a specialty. The strength of co-citation is represented by its frequency, which accumulates over time. Of interest is whether underlying features associated with the strength of co-citation can be identified. We use the proximal citation network for a given pair of articles (x, y) to compute theta, an a priori estimate of the probability of co-citation between x and y, prior to their first co-citation.Thus, low values for theta reflect pairs of articles for which co-citation is presumed less likely. We observe that co-citation frequencies are a composite of power-law and lognormal distributions, and that very high co-citation frequencies are more likely to be composed of pairs with low values of theta, reflecting the impact of a novel combination of ideas. Furthermore, we note that the occurrence of a direct citation between two members of a co-cited pair increases with co-citation frequency. Finally, we identify cases of frequently co-cited publications that accumulate co-citations after an extended period of dormancy.
