An Open Graph Dataset Organized by Scales.

Graph-related technologies, including social networks, transportation systems, and bioinformatics, are continually evolving in various application domains. The advancement of these technologies often relies on high-quality graph datasets for validating performance, such as scalability and time/space complexity. However, existing datasets are typically categorized by domains or types, lacking an explicit organization by scales and a wide range of scale levels. This situation may hinder comprehensive performance validations. This paper introduces an open graph dataset organized by scales named OGDOS. The dataset encompasses 470 preset scale levels, covering node counts from 100 to 200,000 and edge-to-node ratios from 1 to 10. The dataset combines scale-aligned real-world graphs and synthetic graphs, offering a versatile resource for evaluating various graph-related technologies. This paper also presents the OGDOS's construction process, provides a technical validation, and discusses its limitations.
