In this thesis, 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...

With regard to this issue that there is no scientific and complete method for recording lexical units in Persian dictionaries, we decided to propose a scientific method to do the mentioned activity by studying derivational processes, affixes and lexicalization phenomena and its relation...
