Before revision:  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.
After revision:  Our empirical investigation reveals the challenges of existing graph methods in handling large-scale graphs and predicting out-of-distribution generalization under realistic data splits, indicating fruitful opportunities for future research. Finally, OGB provides an automated end-to-end graph ML pipeline that simplifies and standardizes the process of graph data loading, experimental setup, and model evaluation.
