Navigating the complexities of Arabic read ability prediction requires addressing the language’s rich morphology and structural diversity. In the BAREC Shared Task 2025, we participated in all tracks using a stacked ensemble meta learning framework. Our approach combined seven fine-tuned transformer, whose outputs fed into a meta classifier trained on multiple features, including individual predictions, their average, and the average top prediction probabilities. On the blind test set, our ensemble achieved a Quadratic Weighted Kappa (QWK) of 86.4%, demonstrating the effectiveness of integrating diverse transformer encoders for fine grained Arabic readability classification and the potential of meta learning in morphologically rich contexts.

This work presents a hybrid approach to Arabic sentence-level readability assessment for the BAREC 2025 Shared Task (Strict Track). Building on transformer-based architectures, I integrate 51 handcrafted linguistic features 0 covering morphological, syntactic, lexical, and conceptual dimensions- into a hybrid model that combines transformer contextual embeddings with dense feature representations.
The best-performing model, MARBERT, achieved a Quadratic Weighted Kappa (QWK) of 80.95% on the test set and 83.1% on the blind leaderboard, highlighting the potential of combining linguistic indicators with deep contextual features for fine-grained readability classification across 19 levels.

We present a visual-language approach to Arabic readability assessment using the PIXEL Vision Transformer, which processes rendered text as images to bypass tokenization challenges. Our system participated in the BAREC 2025 Shared Task (Sentence-level Strict track). We evaluate orthographic variants (normalization, diacritization, transliteration) and morphological segmentation with different visual boundary markers. Results show that diacritization provides useful visual cues for disambiguation, morphological segmentation improves over word-level processing, and transliterated scripts outperform native Arabic script. Our approach demonstrates the potential of visual processing for readability assessment in complex languages and writing systems.

We presents HUMAIN’s submission to the IslamicEval 2025 Shared Task 1, addressing hallucination detection and correction in Quranic and Hadith LLM-generated content. Our three-stage pipeline covers: (1) Span Detection via sequence-to-sequence annotation using TANL-style markup, (2) Validation with retrieval-based similarity and substring matching against reference corpora, and (3) Correction through exact matching, LCS alignment, and semantic re-ranking. This work presents a multi-stage LLM-based pipeline for Islamic content verification.

We present our systems for the NADI 2025 shared task on multidialectal Arabic speech processing, participating in both spoken dialect identification (ADI) and automatic speech recognition (ASR) subtasks. Working under data constraints by using only the provided shared task resources for dialect adaptation, we explore effective model adaptation strategies for dialectal Arabic speech. For ADI, we fine-tune w2v-BERT 2.0 and employ voice conversion as data augmentation, improving accuracy from 68.71\% to 76.40\% on a blind cross-domain test set. For ASR, we develop two complementary approaches: (1) a CTC-based model pre-trained on public Arabic speech data, and (2) Whisper-based models using two-stage fine-tuning. Our experiments show that while dialect-centric CTC models exhibit better zero-shot dialectal performance (58.89 vs 93.90 WER), Whisper achieves better performance after dialect-specific adaptation, which reduces WER from 93.89 to 39.78 WER. We also demonstrate that using character error rate (CER) as a validation criterion provides practical benefits with minimal performance trade-offs. Despite using no external resources for dialect adaptation beyond the shared task data, our systems ranked second in ADI and third in ASR, demonstrating that careful adaptation strategies can overcome data constraints in dialectal speech processing.

In this paper, we report our participation to the PalmX cultural evaluation shared task. Our system, CultranAI, focused on data augmentation and LoRA fine-tuning of large language models (LLMs) for Arabic cultural knowledge representation. We benchmarked several LLMs to identify the best-performing model for the task. In addition to utilizing the PalmX dataset, we augmented it by incorporating the Palm dataset and curated a new dataset of over 22K culturally grounded multiple-choice questions (MCQs). Our experiments showed that the Fanar-1-9B-Instruct model achieved the highest performance. We fine-tuned this model on the combined augmented dataset of 22K+ MCQs. On the blind test set, our submitted system ranked 5th with an accuracy of 70.50%, while on the PalmX development set, it achieved an accuracy of 84.1%.

This paper presents our system for Subtask 1: Islamic Inheritance Reasoning in the QIAS 2025 Shared Task, which evaluates large language models (LLMs) on ʿilm al-mawārīth (the Islamic science of inheritance) using a benchmark of Arabic multiple-choice questions (MCQs) derived from expert-reviewed fatwas. We explore static and dynamic few-shot prompting, retrieval-augmented generation (RAG) using a large fatwa corpus, and a progressive n-gram overlap retrieval method. The n-gram method is employed both to select the top five most similar MCQs for dynamic prompting and to retrieve the most relevant fatwa answers as additional context during inference. We evaluate both proprietary and open-source LLMs individually and in ensemble configurations. Results show that dynamic prompting and RAG consistently improve accuracy across models, with our best-performing model, Gemini, achieving 62.26% accuracy on the test set.

Word sense disambiguation is the task of selecting a word's applicable word sense in a given context. However, ambiguous texts may lack the information necessary to disambiguate words completely, resulting in multiple word senses with varying degrees of plausibility. We design a dataset around this premise: Our samples consist of 4--5 sentence short stories, where the sentence with the word to be disambiguated is itself ambiguous and surrounding sentences only contain indirect clues towards the more plausible word sense. We collect annotations from humans who rate the plausibility of a given word sense on a scale from 1--5. In total, our dataset contains 19,701 human word sense annotations on 1,899 stories. We investigate the performance of large language models on our data and find that many poorly correlate with human judgments. We also find that fine-tuning on our data can increase performance.

AmbiStory: A Challenging Dataset of Lexically Ambiguous Short Stories

With the introduction of large language models, NLP has undergone a paradigm shift where these models now serve as the backbone of most developed systems. However, while highly effective, they remain opaque and difficult to interpret, which limits their adoption in critical applications that require transparency and trust. Two major approaches aim to address this: rationale extraction, which highlights input spans that justify predictions, and concept bottleneck models, which make decisions through human-interpretable concepts. Yet each has limitations. Crucially, current models lack a unified framework that connects where a model looks (rationales) with why it makes a decision (concepts). We introduce CLARITY, a model that first selects key input spans, maps them to interpretable concepts, and then predicts using only those concepts. This design supports faithful, multi-level explanations and allows users to intervene at both the rationale and concept levels. CLARITY, achieves competitive accuracy while offering improved transparency and controllability.

Connecting Concept Layers and Rationales to Enhance Language Model Interpretability

Cross-lingual Extractive Question Answering (EQA) extends standard EQA by requiring models to find answers in passages written in languages different from the questions. The Generalized Cross-Lingual Transfer (G-XLT) task evaluates models' zero-shot ability to transfer question answering capabilities across languages using only English training data. While previous research has primarily focused on scenarios where answers are always present, real-world applications often encounter situations where no answer exists within the given context. This paper introduces an enhanced G-XLT task definition that explicitly handles unanswerable questions, bridging a critical gap in current research. To address this challenge, we present two new datasets: miXQuAD and MLQA-IDK, which address both answerable and unanswerable questions and respectively cover 12 and 7 language pairs. Our study evaluates state-of-the-art large language models using fine-tuning, parameter-efficient techniques, and in-context learning approaches, revealing interesting trade-offs between a smaller fine-tuned model's performance on answerable questions versus a larger in-context learning model's capability on unanswerable questions. We also examine language similarity patterns based on model performance, finding alignments with known language families.
