The paper details a methodology for digitizing the Al-Mawrid Arabic-English dictionary using ISO LMF and TEI Lex-0. It achieves 91% structural parsing accuracy and demonstrates 85% precision and 98% recall for synonyms, with 88% precision for morpho-semantic features, based on a sample of the letter Ayn. The study highlights TEI Lex-0 limitations in capturing Arabic semantic and morphological nuances and proposes a scalable prefix-based system for LLOD integration.
