A Realization of Optimality Theory to Arabic Hollow Verb

Abstract

Arabic hollow verb has two kind stems of perfective. Those faced three main factors, (1) root and morphological template, (2) phonological aspect, and (3) imperfective form. The previous study had multilevel analysis using concatenative strategy, to account for conjugation of Arabic hollow verb. The other existing studies just investigated one factor, that was phonological harmony; or standard morphological analysis. So, they just got single approach to formulate morphological processes of Arabic hollow verb. In this paper, we demonstrate a unified interplay approach to outline a learning algorithm which utilize the optimality theory to ascertain the optimal output of two kind stem of Arabic perfective hollow verb, exclusively using blocking and extended exponence. Within this approach, the existence of weak consonants (w and y) in hollow verb can be expressed as realization constraints in accordance to Arabic morphology system, that is associated to the pattern of perfective-imperfective change, and also consider grammatical categories (person, number, and gender). The findings of this study is not only useful for theoretical linguists to understand an alternative way of modeling and processing the inflection of Arabic words, but also for computer practitioners who want to develop an algorithm for natural language processing tasks of Arabic hollow verb conjugations.
