Pseudocode Yes as shown in Algorithm 1 in the appendix.
Open Source Code Yes Code and datasets are available at https://github.com/TemporalKGTeam/xERTE
Open Datasets Yes Integrated Crisis Early Warning System (ICEWS) (Boschee et al., 2015) and YAGO (Mahdisoltani et al., 2013) have established themselves in the research community as benchmark datasets of temporal KGs.
Dataset Splits Yes We split quadruples of a temporal KG into train, validation, and test sets by timestamps, ensuring (timestamps of training set)<(timestamps of validation set)<(timestamps of test set).
Hardware Specification No The paper does not provide specific hardware details such as GPU models, CPU types, or memory specifications used for running the experiments.
Software Dependencies No The paper states "We implement our model and all baselines in Py Torch (Paszke et al., 2019)," but it does not specify explicit version numbers for PyTorch or any other software dependencies beyond citing the PyTorch paper from 2019.
Experiment Setup Yes We tune hyperparameters of our model using a grid search. We set the learning rate to be 0.0002, the batch size to be 128, the inference step L to be 3.
