The paper introduces AraSEG, a new Arabic sentence segmentation corpus covering eight genres and diverse punctuation and document structures. Experiments using AraSEG evaluate large language models, lightweight encoders, and dependency parser-based models, revealing that lightweight encoders and parser-based models outperform LLMs under the most challenging conditions. The study also shows that increasing training data size and genre diversity eventually saturates performance, that cross‑genre generalization remains difficult, and that accurate sentence segmentation significantly improves downstream dependency parsing.

The paper evaluates large language models (LLMs) on Arabic morphosyntactic tagging and dependency parsing, a challenging task due to rich morphology and orthographic ambiguity. It compares zero‑shot prompting with retrieval‑based in‑context learning across pre‑tokenized, raw‑text, and cascaded settings, finding that relevant demonstrations significantly boost performance. The best LLMs nearly match supervised systems but need extensive annotated data for demonstrations and high computational resources. All code and data are publicly released.

The paper reports Alkhder’s submission to Subtask 1 of the AlexandriaX-2026 shared task, translating English dialogue turns into thirteen Arabic dialects. The team fine‑tuned NileChat‑3B‑Base with QLoRA on the Alexandria parallel dialogue corpus, training a single set of adapter weights for all dialects. Each translation is conditioned on target country, dialect, domain, participant roles, speaker‑addressee gender direction, and preceding dialogue context, and the model is run autoregressively using its own previous outputs as context. In the constrained track, training takes about one hour and inference on the private test set takes under two hours, achieving a country‑macro‑averaged spBLEU of 20.36 and chrF++ of 36.64 on both tracks.
