Character Iconicity vs. Arbitrariness: An Arabic NLP Perspective

arXiv · Aug 3

Researchers investigated the functional necessity of visual distinctions in Arabic script for NLP by comparing standard dotted, dotless, and arbitrarily remapped Arabic. They generated 2,000 random character remappings constrained to 19 undotted rasms, evaluating them across tasks like language modeling, text classification, and machine translation. The study found that neither preserving original character distinctions nor traditional rasm-based groupings is necessary for strong NLP performance, with random remappings achieving competitive results while reducing vocabulary size and training costs. Why it matters: These findings suggest that Arabic NLP models primarily rely on stable distributional structure rather than visual iconicity, potentially leading to more efficient and effective Arabic language processing.

ArabianGPT: Native Arabic GPT-based Large Language Model

arXiv · Feb 23

The paper introduces ArabianGPT, a suite of transformer-based language models designed specifically for Arabic, including versions with 0.1B and 0.3B parameters. A key component is the AraNizer tokenizer, tailored for Arabic script's morphology. Fine-tuning ArabianGPT-0.1B achieved 95% accuracy in sentiment analysis, up from 56% in the base model, and improved F1 scores in summarization. Why it matters: The models address the gap in native Arabic LLMs, offering better performance on Arabic NLP tasks through tailored architecture and tokenization.

A Tale of Two Scripts: Transliteration and Post-Correction for Judeo-Arabic

arXiv · Jul 7

The paper introduces a two-step approach for transliterating Judeo-Arabic text (written in Hebrew script) into Arabic script. The method involves character-level mapping followed by post-correction to fix grammatical and orthographic errors. The authors also benchmarked LLMs on the transliteration task and demonstrate that transliteration enables the use of Arabic NLP tools on Judeo-Arabic. Why it matters: This work makes Judeo-Arabic texts more accessible to Arabic NLP, enabling processing and analysis that was previously impossible.
