During this period, efforts converged on standardizing dialect orthography across Arabic varieties and codifying Arabizi-to-Arabic mappings to enable cross-dialect literacy and tooling. Computational transliteration pipelines and parallel corpora emerged as core methodologies, while linguistic and historical analyses anchored orthography in earlier scripts and inscriptions. NLP infrastructure, resources, and annotation frameworks coalesced to support scalable processing and evaluation of dialect writing. Historical Significance: The period situates contemporary orthography within longer script trajectories, drawing on Quranic rasm, phonetic conservatism, and epigraphic evidence to contextualize modern dialect writing. Foundational works established a conventional orthography for Tunisian Arabic and created frameworks for transliteration and MWEs annotation, providing stable references for cross-dialect resource development and comparative work. Together, these efforts created enduring methodological templates—standardized scripts, reusable transliteration pipelines, and annotation schemes—that influenced later research across dialects and digital writing.
