论文摘要
实体对准始终在许多不同的科学领域中具有重大用途。特别是,随着社交媒体等交流网络(例如社交媒体)的规模和知名度扩大,跨网络匹配实体的概念在社会科学领域具有重要意义。随着大数据的出现,越来越需要在大规模的图表上提供分析。但是,使用数百万个节点和数十亿个边缘,使用从潜在的稀疏或不完整数据集中提取的特征在无数类似尺度的众多图表之间进行对齐的想法变得令人生畏。在本文中,我们将提出一种解决多步管道形式的大规模对齐问题问题的解决方案。在此管道中,我们引入了可扩展的特征提取,以实现鲁棒的时间属性,并伴随新型和有效的聚类算法,以便在图中找到相似节点的分组。这些功能及其簇被馈入多功能的对齐阶段,该阶段可以准确地识别数百万个可能的匹配中的合作伙伴节点。我们的结果表明,管道可以处理大型数据集,从而在内存约束中获得有效的运行时间。
Entity alignment has always had significant uses within a multitude of diverse scientific fields. In particular, the concept of matching entities across networks has grown in significance in the world of social science as communicative networks such as social media have expanded in scale and popularity. With the advent of big data, there is a growing need to provide analysis on graphs of massive scale. However, with millions of nodes and billions of edges, the idea of alignment between a myriad of graphs of similar scale using features extracted from potentially sparse or incomplete datasets becomes daunting. In this paper we will propose a solution to the issue of large-scale alignments in the form of a multi-step pipeline. Within this pipeline we introduce scalable feature extraction for robust temporal attributes, accompanied by novel and efficient clustering algorithms in order to find groupings of similar nodes across graphs. The features and their clusters are fed into a versatile alignment stage that accurately identifies partner nodes among millions of possible matches. Our results show that the pipeline can process large data sets, achieving efficient runtimes within the memory constraints.
