Paper link: https://arxiv.org/abs/2204.13957

Results

The results of PIE powered TransE model is as follows.

ogb-lsc-wikikg90mv2

	#Parameters	Test MRR	Valid MRR
TransE-shallow-PIE	18,247,074,200	0.1883	0.2342

System requirements:

It's recommended to use a machine with over 400G memory to reproduce the results.

Reproducing the Results on WikiKG90Mv2

---

1, Entity Typing

The model implementation is based on PathCon. Thanks for their contributions.

cd entity_typing && sh run.sh DATA_PATH

The ${DTA_PATH} should conatin train_hrt.npy.

After model training and inference, the code will output the distributuon p(r|e) for each entity. As the dataset is too large, we save the results with 15 sparse matrices. Please use src/cat_npz.py to concatenate all the sparse matrices. cd src && python/cat_npz.py $SAVE_PATH This will save the $p(r|e)$ matrix for all entities at ${SAVE_PATH}/e2r_scores.npz.

2, Candidate Generation

The sampling implementation is based on dgl-ke. Thanks for their contributions.

cd candidate && sh run.sh DATA_PATH

The ${DATA_PATH} should contain folders, such as 'raw' and 'processed'. As we utilize multi processer to sampling the candidates and each processor saves the result individually, please use script src/cat.py to concatenate all the candidates to one file.

3, Knowledge Graph Embedding Reansoning

The KGE implementation is based on the official baseline code of WikiKG90M OGB. Thanks for their contributions.
