AlKhalil Morpho Sys 2: A robust Arabic morpho-syntactic analyzer

AlKhalil Morpho Sys is a morphosyntactic analyzer of standard Arabic words taken out of context. The system analyzes either partially vowelized words or totally vowelized ones. In this paper, we present the second version of this analyzer. The correction of errors in the database of the first version, and enrichment of this database by missing data allowed us to develop a more accurate version with very high coverage since the percentage of analyzed words exceeds 99%. In addition, we have enriched the morphological features provided by this new version with the lemma tag of the word and its pattern, which are very useful in many applications of Arabic language processing. Furthermore, with the new organization of this database and the improvements brought to its source code, this new version produces very fast analysis.
