Deterministic Finite State Automaton of Arabic Verb System: A Morphological Study
M. Mahyoob. International Journal of Computational Linguistics (IJCL)9 (1):
Finite State Morphology serves as an important tool for investigators of natural language processing. Morphological Analysis forms an essential preprocessing step in natural language processing. This paper discusses the morphological analysis and processing of verb forms in Arabic. It focuses on the inflected verb forms and discusses the perfective, imperfective and imperatives. The deterministic finite state morphological parser for the verb forms can deal with Morphological and orthographic features of Arabic and the morphological processes which are involved in Arabic verb formation and conjugation. We use this model to generate and add all the necessary information (prefix, suffix, stem, etc.) to each morpheme of the words; so we need subtags for each morpheme. Using Finite State tool to build the computational lexicon that are usually structured with a list of the stems and affixes of the language together with a representation that tells us how words can be structured together and how the network of all forms can be represented.
