Source code and datasets for IJCAI 2019 paper: Relation-Aware Entity Alignment for Heterogeneous Knowledge Graphs.

Initial datasets are from GCN-Align and JAPE.

Dependencies

• Python>=3.5
• Tensorflow>=1.8.0
• Scipy>=1.1.0
• 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).

Datasets

Please first download the datasets here and extract them into data/ directory.

There are three cross-lingual datasets in this folder:

• fr-en
• ja-en
• zh-en

Take the dataset DBP15K (ZH-EN) as an example, the folder "zh_en" contains:

• ent_ids_1: ids for entities in source KG (ZH);
• ent_ids_2: ids for entities in target KG (EN);
• ref_ent_ids: entity links encoded by ids;
• triples_1: relation triples encoded by ids in source KG (ZH);
• triples_2: relation triples encoded by ids in target KG (EN);
• zh_vectorList.json: the input entity feature matrix initialized by word vectors;

Running

• Modify language or some other settings in include/Config.py
• cd to the directory of main.py
• run main.py

Due to the instability of embedding-based methods, it is acceptable that the results fluctuate a little bit (±1%) when running code repeatedly.
