National Hellenic Research Foundation Athens Greece - EUROTRA - GR Athens Greece ABSTRACT In this paper we present a morphological processor for Modern Greek. From the linguistic point of view we try to elucidate the complexity of the inflectional system using a lexical model which follows the recent work by Lieber 1980 Selkirk 1982 Kipar-sky 1982 and others. The implementation is based on the concept of validation grammars Courtin 1977 . The morphological processing is controlled by a finite automaton and it combines a. a dictionary containing the stems for a representative fragment of Modern Greek and all the inflectional affixes with b. a grammar which carries out the transmission of the linguistic information needed for the processing. The words are structured by concatenating a stem with an inflectional part. In certain cases phonological rules are added to the grammar in order to capture lexical phonological phenomena. 1. Introduction-Overview Our processor is intended to provide an analysis as well as a generation for every derived item of the greek lexicon. It covers both inflectional and derivational morphology but for the time being only inflection has been treated. Greek is the only language tested so far. Nevertheless we hope that our system is general enough to be of use to other languages since the formal and computational aspect of validation grammars and finite automata has already been used for French . Courtin et al. 1976 Galio-tou 1983 . The system is built around the following data files 1. A dictionary holding morphemes associated to morpho-syntactic information. 2. A model file containing items which act as reference to every morphematic entry in order to determine what kind of process the entry undergoes . 3. A word grammar which governs permissible word
