Source code and datasets for ACL 2020 paper: Neighborhood Matching Network for Entity Alignment.
Please first download the datasets here and extract them into
data/directory.
Initial datasets DBP15K and DWY100K are from JAPE and BootEA.
Take the dataset DBP15K (ZH-EN) as an example, the folder "zh_en" contains:
- ent_ids_1: ids for entities in source KG;
- ent_ids_2: ids for entities in target KG;
- ref_ent_ids: entity links encoded by ids;
- triples_1: relation triples encoded by ids in source KG (DBP_ZH);
- triples_1_s: remaining relation triples encoded by ids in source KG (S-DBP_ZH);
- triples_2: relation triples encoded by ids in target KG (DBP_EN);
- triples_2_s: remaining relation triples encoded by ids in target KG (S-DBP_EN);
- vectorList.json: the input entity feature matrix initialized by word vectors;
- Python>=3.5
- Tensorflow>=1.8.0
- Scipy
- Numpy
Due to the limited graphics memory of GPU, we ran our codes using CPUs (40 Intel(R) Xeon(R) CPU E5-2640 v4 @ 2.40GHz).
For example, to run NMN on DBP15K (ZH-EN), use the following script:
python3 main.py --dataset DBP15k --lang zh_en
Due to the instability of embedding-based methods, it is acceptable that the results fluctuate a little bit (±1%) when running code repeatedly.
If you have any difficulty or question in running code and reproducing expriment results, please email to wyting@pku.edu.cn.
