Classical dictionary Al-Qamus in lemon

In order to enrich the digital content of Classical Arabic, we aim to propose and represent the Arabic dictionary “'Al-Qamiis Al-Muhit” in the standard format LEMON. Printed transition to digital format requires various steps of work. This article describes the procedures that we followed to convert the dictionary in digitized and encoded format to apply automatic extractions and get the Lemon format used in semantic web. Furthermore, due to Arabic dictionary complexity, formalize lexical and semantic information involves morphosyntactic and derivational knowledge that we try to explain.
