论引文网络的稳定性

On the Stability of Citation Networks

Alexandre Benatti, Henrique Ferraz de Arruda, Filipi Nascimento Silva, César H. Comin, Luciano da Fontoura Costa

摘要:

引文网络可以揭示许多关于科学发展和不同知识领域之间关系的重要信息。因此,许多研究分析了这种网络的拓扑性质。通常,引文网络是使用从一组相关关键字或查询中获取的文章创建的。在这里,我们研究了引文网络的鲁棒性方面的关键字,用于收集各自的文章。提出了一种扰动方法,量化了关键词缺失对引文网络拓扑结构和社团结构的影响。此外,关键词和引文网络的社区结构之间的关系进行了研究,使用网络从一个简单的模型。我们发现,由于其高度模块化的结构,社区结构的引文网络往往被保留,即使许多相关的关键字被遗漏。此外,所提出的模型可以反映不同情况下的关键字丢失的影响。

英文摘要:

Citation networks can reveal many important information regarding the development of science and the relationship between different areas of knowledge. Thus, many studies have analyzed the topological properties of such networks. Frequently, citation networks are created using articles acquired from a set of relevant keywords or queries. Here, we study the robustness of citation networks with regards to the keywords that were used for collecting the respective articles. A perturbation approach is proposed, in which the influence of missing keywords on the topology and community structure of citation networks is quantified. In addition, the relationship between keywords and the community structure of citation networks is studied using networks generated from a simple model. We find that, owing to its highly modular structure, the community structure of citation networks tends to be preserved even when many relevant keywords are left out. Furthermore, the proposed model can reflect the impact of missing keywords on different situations.
