2. When you untar drkg.tar.gz, you will find drkg.tsv.

3. Add drkg.tsv to Input/DRKG.

Quick Tour

• TrainGNN.ipynb : Takes as input drkg.tsv and outputs a trained Graph Neural Network (can be either GCN, GraphSAGE or GAT) to Output/GNNModels.
• ExplainabilityUseCase.ipynb : Takes as input a model and its precitions, and returns a dictionary (for a specific use case) containing the most important nodes that were most influential for the prediction(s) using Saliency Maps.
• PlotSubgraph.ipynb : Plots the explanatory subgraph.
