Source code for CIKM 2021 paper Reinforced Active Entity Alignment

Codes based on EAkit. Thanks for their contribution!

Dependencies

Please refer to EAkit.

Datasets

There are eight datasets in this folder:

• zh_en/ja_en/fr_en from the DBP15K dataset
• en_fr/en_de/dbp_wd/dbp_yg from the SRPRS dataset
• DBP-FB dataset

Please unzip them in the data/ directory.

Take the dataset DBP15K (ZH-EN) as an example, it contains:

• ent_ids_1: ids for entities in source KG (ZH);
• ent_ids_2: ids for entities in target KG (EN);
• ill_ent_ids: entity links encoded by ids;
• ref_ent_ids: entity links for testing/validation;
• sup_ent_ids: entity links for training;
• triples_1: relation triples encoded by ids in source KG (ZH);
• triples_2: relation triples encoded by ids in target KG (EN);

Query strategy scores

We have already provided the scores of the degree and Pagerank metrics in the datasets. The codes for generating such scores are also provided in the data/ directory.

Running

• Run

bash run_rl.sh

Change the parameters in run_rl.sh to obtain the results under other settings.

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