ConMask

Code for AAAI'18 paper: Open-world Knowledge Graph Completion.

The datasets and pre-trained models can be found at https://drive.google.com/open?id=1YBKw4nOnbscpDeTD_gWxfcpHRFG3MY20

Warning: Current implementation needs a machine with four GPUs, this could be reduced to 1 GPU but needs code modification.

Run the code

Compile C++ Operator

Go to ndkgc/ops/__sampling, run

cmake .
cmake --build .

to compile the negative sampling operator using CMake and TensorFlow.

If you can not compile this C++ operator, please consider downgrade your TensorFlow to 1.3. PRs to fix this is welcomed.

Download per-trained model snapshot

Download DB50 from

https://drive.google.com/file/d/1qw8d0LGT18D_3p2_dNmyqztkgZO4ageW/view?usp=sharing

put the DB50 dataset under ConMask/data.

Download pre-trained ConMask model from
