# Vietnamese Business Entity Resolution Dataset — Embedding Focused

Synthetic benchmark cho bài toán Entity Resolution trên dữ liệu doanh nghiệp
Việt Nam từ ba nguồn:

- `business_registry`
- `tax_registry`
- `inspection_record`

## Dataset design

- Entities: 12,000
- Records: 34,708
- Entity-level split: 70% train, 15% validation, 15% test
- Mọi record của cùng một entity luôn nằm trong cùng một split
- Phần lớn entity có đủ 3 nguồn; một tỷ lệ nhỏ thiếu hoặc có thêm record
- Positive pairs: lexical, semantic-only và mixed/hard

## Subsets

| Subset | Nội dung |
|---|---|
| `observed_records` | Toàn bộ bản ghi quan sát |
| `business_registry` | Bản ghi đăng ký doanh nghiệp |
| `tax_registry` | Bản ghi cơ quan thuế |
| `inspection_record` | Bản ghi kiểm tra |
| `record_split_map` | Ánh xạ record sang split |
| `ground_truth_entity_map` | Ground-truth entity |
| `all_positive_pairs` | Các cặp match thật |
| `hard_negative_pairs` | Các cặp non-match khó |
| `record_generation_metadata` | Metadata sinh dữ liệu |
| `canonical_entities` | Entity chuẩn |

## Split policy

Việc chia dữ liệu được thực hiện ở cấp entity, không phải cấp record.

Do đó, một doanh nghiệp và toàn bộ record tương ứng của nó chỉ xuất hiện
trong đúng một trong ba split: `train`, `validation` hoặc `test`.

Điều này ngăn entity leakage giữa các tập dữ liệu.
