Computational contributions for Arabic language processing Part I. The automatic morphologic analysis of Arabic texts

problems of ambiguity inherent to the Arabic language. Difficulties arose in the various stages of automatic processing of the Arabic version of Plotinus, the text which lies at the core of our project. Part I highlights the needs that led us to update the morphological engine AraMorph in order to optimize its morpho-syntactic analysis. Even if the engine has been optimized, a digital lexical source for better use of the system is still lacking. Part II presents a methodology exploiting the internal structure of the Arabic lexicographic encyclopaedia Lisan al-"arab, which allows automatic extraction of the roots and derived lemmas. The outcome of this work is a useful resource for morphological analysis of Arabic, either in its own right, or to enrich already existing resources
