# BAREC Shared Task 2025
## Dataset Summary
**BAREC** (the Balanced Arabic Readability Evaluation Corpus) is a large-scale dataset developed for the **BAREC Shared Task 2025**, focused on **fine-grained Arabic readability assessment**. The dataset includes over **1M words**, annotated across **19 readability levels**, with additional mappings to coarser 7, 5, and 3 level schemes.
The dataset is **annotated at the sentence level**. Document-level readability scores are derived by assigning each document the readability level of its **most difficult sentence**, based on the 19-level scheme. This provides both **sentence-level** and **document-level** readability information.
---
## Supported Tasks and Leaderboards
The dataset supports **multi-class readability classification** in the following formats:
- **19 levels** (default)
- **7 levels**
- **5 levels**
- **3 levels**
For details on the shared task, evaluation setup, and leaderboards, visit the [Shared Task Website](https://barec.camel-lab.com/sharedtask2025).

### Languages

## Dataset Structure
### Data Instances
`{'ID': 10100010008, 'Sentence': 'عيد سعيد', 'Word_Count': 2, 'Readability_Level': '2-ba', 'Readability_Level_19': 2, 'Readability_Level_7': 1, 'Readability_Level_5': 1, 'Readability_Level_3': 1, 'Annotator': 'A4', 'Document': 'BAREC_Majed_0229_1983_001.txt', 'Source': 'Majed', 'Book': 'Edition: 229', 'Author': '#', 'Domain': 'Arts & Humanities', 'Text_Class': 'Foundational'}`
### Data Fields
- **ID**: Unique sentence identifier.
- **Sentence**: The sentence text.
- **Word_Count**: Number of words in the sentence.
- **Readability_Level**: The readability level in `19-levels` scheme, ranging from `1-alif` to `19-qaf`.
- **Readability_Level_19**: The readability level in `19-levels` scheme, ranging from `1` to `19`.
- **Readability_Level_7**: The readability level in `7-levels` scheme, ranging from `1` to `7`.
- **Readability_Level_5**: The readability level in `5-levels` scheme, ranging from `1` to `5`.
- **Readability_Level_3**: The readability level in `3-levels` scheme, ranging from `1` to `3`.
- **Annotator**: The annotator ID (`A1-A5` or `IAA`).
- **Document**: Source document file name.
- **Source**: Document source.
- **Book**: Book name.
- **Author**: Author name.
- **Domain**: Domain (`Arts & Humanities`, `STEM` or `Social Sciences`).
- **Text_Class**: Readership group (`Foundational`, `Advanced` or `Specialized`).
### Data Splits
- The BAREC dataset has three splits: *Train* (80%), *Dev* (10%), and *Test* (10%).
- The splits are in the document level.
- The splits are balanced accross *Readability Levels*, *Domains*, and *Text Classes*.

## Evaluation
We define the Readability Assessment task as an ordinal classification task. The following metrics are used for evaluation:
- **Accuracy (Acc<sup>19</sup>):** The percentage of cases where reference and prediction classes match in the 19-level scheme.
- **Accuracy (Acc<sup>7</sup>, Acc<sup>5</sup>, Acc<sup>3</sup>):** The percentage of cases where reference and prediction classes match after collapsing the 19 levels into 7, 5, or 3 levels, respectively.
- **Adjacent Accuracy (±1 Acc<sup>19</sup>):** Also known as off-by-1 accuracy. The proportion of predictions that are either exactly correct or off by at most one level in the 19-level scheme.
- **Average Distance (Dist):** Also known as Mean Absolute Error (MAE). Measures the average absolute difference between predicted and true labels.
- **Quadratic Weighted Kappa (QWK):** An extension of Cohen’s Kappa that measures the agreement between predicted and true labels, applying a quadratic penalty to larger misclassifications (i.e., predictions farther from the true label are penalized more heavily).
We provide evaluation scripts [here](https://github.com/CAMeL-Lab/barec-shared-task-2025).
