# RWT-RuTaBERT

Dataset based on [Russian Web Tables](https://arxiv.org/abs/2210.06353) (RWT), which is a corpus of Russian language tables from Wikipedia.

Only relational tables were chosen from _RWT_ with headers matching selected **170** DBpedia semantic types.

Dataset contains `1 441 349` columns, and has fixed train / test split. 

| Split | Columns   | Tables  | Avg. columns per table |
|-------|-----------| ------- | ---------------------- |
| Test  | 115 448   | 55 080  | 2.096                  |
| Train | 1 325 901 | 633 426 | 2.093                  |
