ArabLEX
Arabic Full-Form Lexicon

CJKI’s Arabic Full-Form Lexicon, or ArabLEX, is the most comprehensive Arabic computational lexicon ever created, covering over 530 million entries.

As a full-form lexicon, ArabLEX includes all inflected forms for Modern Standard Arabic and covers not only general vocabulary but also, for the first time, fully inflected proper nouns (personal and place names).

ArabLEX is an essential resource for any development project involving Arabic NLP or AI. It is suited for such applications as machine translation, speech technology, deep learning, and cybersecurity.

As one such example, ArabLEX has significantly contributed to the development of Amazon’s advanced Arabic speech technology for both speech synthesis (TTS) and speech recognition (ASR). Due to its comprehensiveness and the fact that it covers morphology and phonology in depth, it has helped Amazon build a robust data-driven model that reduces the error rates for both recognition and generation; that is, it enables Amazon’s Alexa technology to recognize Arabic queries, including place and personal names, as well as generate answers with greater precision.

NOTE: Full-form lexicons for the Arabic dialects Egyptian, Hijazi and Emirati are also available.
