引文模式对网络结构的影响

Effect of citation patterns on network structure

Soma Sanyal

摘要:

我们提出了一个不断发展的引用网络模型,该模型结合了特定学科中的引用模式。我们用三个因素来定义一个学科的引文模式。每篇文章的平均引用次数,基于其年龄和引用次数的引用概率。我们还考虑了该学科每年发表的文章的平均数量。我们建议,引用的概率基于其年龄的文章可以建模的寿命分布。生命周期分布模拟了特定学科中平均文章的引用寿命。我们发现,在一个特定的学科的引文寿命分布预测的拓扑结构的引文网络在该学科。我们发现,幂律指数取决于定义的引用模式的三个因素。最后,我们从物理评论D期刊的数据拟合得到的引文模式和计算的总度分布的引文网络。

英文摘要:

We propose a model for an evolving citation network that incorporates the citation pattern followed in a particular discipline. We define the citation pattern in a discipline by three factors. The average number of references per article, the probability of citing an article based on its age and the number of citations it already has. We also consider the average number of articles published per year in the discipline. We propose that the probability of citing an article based on its age can be modeled by a lifetime distribution. The lifetime distribution models the citation lifetime of an average article in a particular discipline. We find that the citation lifetime distribution in a particular discipline predicts the topological structure of the citation network in that discipline. We show that the power law exponent depends on the three factors that define the citation pattern. Finally we fit the data from the Physical Review D journal to obtain the citation pattern and calculate the total degree distribution for the citation network.
