SelfKG: Self-Supervised Entity Alignment in Knowledge Graphs

Original implementation for paper SelfKG: Self-Supervised Entity Alignment in Knowledge Graphs.

This paper is accepted and nominated as a best paper by The Web Conference2022! 😆

SelfKG is the first self-supervised entity alignment method without label supervision, which can match or achieve comparable results with state-of-the-art supervised baselines. The performance of SelfKG suggests self-supervised learning offers great potential for entity alignment in Knowledge Graphs.

You can also use the following scripts to download the datasets directly:

cd data
bash getdata.sh # The download speed is decided by your network connection. If it's pretty slow, please directly download the datasets from the website as mentioned before.

⭐Run Experiments

Please use

bash run.sh

to reproduce our experiments results. For more details, please refer to run.sh and our code.

❗ Common Issues

"XXX file not found"

Please make sure you've downloaded all the dataset according to README.
