| # Indic Contextual Post-OCR Correction |
| ## Dataset Summary |
| This dataset supports **contextual post-OCR correction** for Indic languages. Each example is a **sentence-level triple** consisting of: |
| - an **OCR-generated sentence** (noisy), |
| - the **preceding sentence** used as **context**, and |
| - the **corrected sentence** (ground truth). |

|
|
| ## Supported Tasks |
| - Post-OCR text correction (sentence-level) |
| - Context-aware text generation for correcting OCR noise |
| - Evaluation with/without preceding-sentence context |
|
|
| ## Languages |
| - Hindi (`hi`) — Devanagari |
| - Gujarati (`gu`) |
| - Marathi (`mr`) — Devanagari |
|
|
| ## Dataset Structure |
|
|
| ### Configs (language-wise subsets) |
| This dataset is organized into three configs: |
| - `hi` (Hindi) |
| - `mr` (Marathi) |
| - `gu` (Gujarati) |
|
|
| Each config contains `train`, `validation`, and `test` splits. |
|
|
| ### Data Instances |
| A typical instance: |
| ```json |
| { |
| "ocr_sentence": "...", |
| "context_sentence": "...", |
| "ground_truth": "..." |
| } |
| ``` |
