Complex Concept-Based Readability Estimation from Arabic Curriculum
This article introduces DARES 2.0, an enhanced concept-based readability training dataset for Saudi educational texts. It extends the scope of conceptual complexity by revising input features with unique terms and contexts from SaudiTextBooks (grades 1-12). DARES 2.0 is used to fine-tune transformer models like XLM-R Base, mBERT, AraELECTRA, AraBERTv2, and CAMELBERTmix. The findings suggest the need for further development of the dataset and experimental setup to ensure a larger, higher-quality dataset, support extensive fine-tuning, explore transfer learning, and enhance Arabic concept diversity. This work aims to advance concept-based readability estimation in educational contexts.
Executive Impact: Elevating Arabic Educational Content
Core Problem: Existing Arabic readability assessment tools primarily focus on linguistic complexity (word length, sentence length) and suffer from limitations in datasets. For example, DARES 1.0 contained duplicates, abridged texts, and non-unique conceptual words, limiting its practical relevance for nuanced concept-based readability estimation in educational settings.
Our Opportunity: DARES 2.0 addresses the limitations of previous datasets by offering an enhanced, concept-based readability training dataset for Saudi educational texts. By focusing on unique conceptual words and their contexts, it enables a more nuanced analysis of educational materials' conceptual density and complexity. This allows for more effective readability estimation tailored to curriculum development and student learning stages.

| Metric | DARES 1.0 | DARES 2.0 |
|---|---|---|
| No. of concepts | 13,335 | 13,870 |
| No. of unique concepts | 2,989 | 9,817 |
| No. of unique tokens in ‘Text’ | 68,085 | 121,226 |
DARES 2.0 significantly increases the number of unique concepts and total unique tokens compared to DARES 1.0, making it a more challenging and relevant dataset for concept-based readability assessment. This enhancement addresses previous limitations such as duplicates and abridged texts.
CAMELBERTmix: Leading Performer in Arabic Readability
Context: The study evaluated several transformer models on DARES 2.0 for both coarse-grained (4 educational levels) and fine-grained (12 individual grades) readability assessment.
Challenge: DARES 2.0's increased complexity and unique concepts posed a greater challenge compared to DARES 1.0, leading to a slight performance drop across models, suggesting DARES 1.0 might have shown inflated results due to less complex or redundant data.
Solution: Among the models tested (XLM-R Base, mBERT, AraELECTRA, AraBERTv2, CAMELBERTmix), CAMELBERTmix consistently demonstrated the strongest performance. For coarse-grained tasks, it achieved a Weighted F1 of 0.81 and Macro F1 of 0.66 (Subject + Concept + Text input). For fine-grained tasks, it achieved a Weighted F1 of 0.59 and Macro F1 of 0.42 (Text only input).
Impact: CAMELBERTmix's robust performance, even with the more challenging DARES 2.0, highlights its suitability for processing Arabic text across multiple levels of conceptual difficulty and its adaptability to varying dataset complexities. This makes it a promising model for future advancements in concept-based readability estimation.

Your AI Implementation Roadmap
A strategic plan to integrate advanced Arabic readability estimation into your workflows, ensuring maximum impact and sustainable growth.
Phase 1: Dataset Augmentation & Model Refinement
Augment DARES 2.0 with additional context, paraphrasing, and diverse Arabic concepts. Experiment with different learning rates, batch sizes, optimizers, and dropout rates to stabilize training and enhance model generalization. Explore transfer learning from other languages.
Phase 2: Advanced Concept Classification
Develop DARES 3.0 to classify concepts based on features like concrete vs. abstract, literal vs. figurative, local vs. global, and static vs. dynamic. This will enable a more granular analysis of conceptual complexity.
Phase 3: Innovative Arabic Language Models
Research and develop new Arabic language models specifically designed for complex cognitive tasks. This includes refining pre-training datasets to better represent Arabic diversity and investigating novel architectures for enhanced semantic understanding in readability.
Phase 4: Collaborative Resource Development
Foster collaborative efforts within the Arabic NLP community to create shared resources, such as annotated datasets for cognitive classification, to effectively manage the complex demands of concept-based tasks and culturally nuanced Arabic applications.
