Principal Arabic Lexical Resources
كُلُّ عَام وَأَنْتُم بخَيْر
Arabic, one of the six official languages of the United Nations, is spoken by 246 million speakers worldwide -- not only in North Africa and the Middle East, but also in many other countries since it is the language of the Koran.
Though Arabic is playing an increasingly important role in the world today, few lexical and linguistic resources are available for it. The CJK Dictionary Institute has been engaged in the development of comprehensive Arabic lexical databases, with a special focus on proper nouns. These resources, described below, are designed for machine translation and various natural language processing applications such as named entity recognition and anti-money laundering programs.
- Database of Arab Names (DAN).
A comprehensive database covering over 6.5 million Arab names and variants, based on authoritative resources and extensively proofread by a team of Arabic native speaker editors.
- Arab Name Transcription Engine Demo (ANTE).
Powered by our DAN and DANA products, this demonstration site showcases the coverage and breadth these two databases offer.
- The CJKI Arabic Verb Conjugator (CAVE).
An interactive Arabic-English verb conjugation application for iOS devices that provides conjugation paradigms for over 1,600 Arabic verbs.
