**KarantaOCR-Bench** is a unit-test–style evaluation dataset, similar to [olmOCR-bench](https://huggingface.co/datasets/allenai/olmOCR-bench). It consists of **70 PDF documents** and **300 test cases** spanning multiple document types. |
|
|
All the tests were manually verified by us. |
|
|
KarantaOCR-Bench is designed specifically to evaluate document text extraction for **Documents with diacritics and special characters**, covering a diverse range of document formats and languages commonly under-represented in existing OCR benchmarks. |
|
|
|
|
|
### Data Schema |
|
|
|
|
|
Below is a schema of each test case and what it means: |
|
|
|
|
|
- `pdf [str]`: This is the name of the pdf file in the `pdf` directory |
|
|
- `page [str]`: This is the page of the document for this test case |
|
|
- `id [str]`: Unique ID for this test case |
|
|
- `type [str]`: This is the test type; a description of each test type can be found in the next section |
|
|
- `max_diffs [int]`: This is the maximum allowable difference in the OCR outputs and test case for it to pass |
|
|
- `text [str]`: This is the text span that we search for in the OCR outputt. |
|
|
- `case_sensitive [bool]`: This indicates whether the test case is case sensitive or not |
|
|
- `checked [str]`: This indicates whether or not we have verified this test case manually |
|
|
- `url [str]`: The original file name of the document |
|
|
- `before [str]`: This only applies to text-order tests and this is the text span that should exist before |
|
|
- `after [str]`:This only applies to text-order tests and this is the text span that should exist after |
|
|
|
|
|
|
|
|
### Test Case Types |
|
|
|
|
|
KarantaOCR-Bench is designed to augment OlmoOCR test with an additional test category for Diacritics and Special Chars: |
|
|
|
|
|
* **Presence:** |
|
|
Presence tests check whether a provided span of text exists in the OCR output. Matches are evaluated with a tolerance defined by the `max_diffs` field, allowing for limited character-level differences. |
