Pars Morph: A Persian Morphological Analyzer

In this paper, the theoretical foundation, the way of implementation and the uses of Pars Morph, a Persian morphological analyzer is introduced. Pars Morph is a rule-based Persian morphological analysis system, which analyzes the internal structure of word in Persian and determines the grammatical category and function of the word parts. Pars Morph being in link with a lexicon covering about 45000 lexemes and based on morphological rules in Persian can analyze the structure of complex lexemes and their possible inflected forms and even out-of-lexicon words. Accuracy rate of the first version of Pars Morph is about 95% which could be enhanced to 100% by applying the regulations on Persian language homographs, some syntactic features and typical features of Persian script. Pars Morph can be used in pure linguistics studies as well as in automatic analysis of Persian language.
