Open Graph Benchmark: Datasets for Machine Learning on Graphs

05/02/2020 ∙ by Weihua Hu, et al. ∙ 63

We present the Open Graph Benchmark (OGB), a diverse set of challenging and realistic benchmark datasets to facilitate scalable, robust, and reproducible graph machine learning (ML) research. OGB datasets are large-scale, encompass multiple important graph ML tasks and cover a diverse range of domains, ranging from social and information networks to biological networks, molecular graphs, and knowledge graphs. For each dataset, we provide a unified evaluation protocol using application-specific data splits and evaluation metrics. Our empirical investigation reveals the challenges of existing graph methods in handling large-scale graphs and predicting out-of-distribution data. OGB presents an automated end-to-end graph ML pipeline that simplifies and standardizes the process of graph data loading, experimental setup, and model evaluation. OGB will be regularly updated and welcomes inputs from the community. OGB datasets as well as data loaders and evaluation scripts are available at https://ogb.stanford.edu .
