*PubTables-v2* is a new large-scale dataset for full-page and multi-page table extraction.

## Collections
It comes in 3 collections:
### Cropped Tables

- **135,578** cropped tables, with each sample containing exactly one table cropped closely to its border
- In contrast with PubTables-1M, all of the cropped tables in this collection are either long (30 or more rows) or wide (12 or more columns)
- The data in this collection supports the traditional table structure recognition (TSR) task
- Note: **5,804** of these tables are currently part of an unreleased, private test set
### Single Pages

- **467,541** individual document pages, with each page containing 1 or more tables
- This collection contains **548,414** tables annotated in their full-page context
- The data in this collection supports the task of TD and the task of end-to-end table extraction (TE), or TSR in a full-page context
- Note: **43,288** of these pages are currently part of an unreleased, private test set
### Full Documents

- **9,172** full documents, with all pages included and all tables annotated
- This collection focuses on multi-page tables specifically—every document contains at least one multi-page table
- In total there are **9,492** multi-page tables, **630** single-page tables split across multiple columns, and **14,740** single-page, single-part tables
- The data in this collection supports the tasks of multi-page TD, multi-page TSR (cell structure and content but not location), and cross-page table continuation prediction
Note: A small percentage of the samples in PubTables-v2 are currently part of a private, unreleased test set.
These samples are held back to evaluate data leakage for the public test set in future models and will be released at some point in the future. |
