Source code and datasets for IJCAI-2018 paper "Bootstrapping Entity Alignment with Knowledge Graph Embedding".

Folder "dataset" contains the id files of DWY100K.

The subfolder "mapping/0_3" contains the id files used in BootEA and MTransE while the subfolder "sharing/0_3" is for JAPE and IPTransE. The two datasets use 30% reference entity alignment as seeds. Id files in "sharing/0_3" are generated following the idea of parameter sharing that lets the two aligned enitites in seed alignment share the same id, while "mapping/0_3" does not.

The subfolder "mapping/0_3" inculdes the following files:

• ent_ids_1: entity ids in the source KG;
• ent_ids_2: entity ids in the target KG;
• ref_ent_ids: entity alignment for testing, list of pairs like (e_s, \t, e_t);
• sup_ent_ids: seed entity alignment (training data);
• rel_ids_1: relation ids in the source KG;
• rel_ids_2: relation ids in the target KG;
• triples_1: relation triples in the source KG;
• triples_2: relation triples in the target KG;

The subfolder "sharing/0_3" inculdes the following additional files:

• attr_ids_1: attribute ids in the source KG;
• attr_ids_2: attribute ids in the target KG;
• attr_range_type_1: attribute ranges in the source KG, list of pairs like (attribute id, \t, range code);
• attr_range_type_2: attribute ranges in the target KG;
• ent_attrs_1: entity attributes in the source KG;
• ent_attrs_2: entity attributes in the target KG;
• ref_ents: seed entity alignment denoted by URIs (training data);
