In this paper, we present a morphological processor for Modern Greek.From the linguistic point of view, we tr 5, to elucidate the complexity of the inflectional system using a lexical model which follows the mecent work by Lieber, 1980, Selkirk 1982, Kiparsky 1982, and others.The implementation is based on the concept of "validation grammars" (Coumtin 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 camries 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.i. Intu'oduction-Ovemview 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 (c.f. Courtin et al. 1976, Galiotou 1983).The system is built around the following data files: I.A "dictionary" holding morphemes associated to morpho-syntactic information. 4. A list of phonemes described as sets of features. The same file contains also a set of phonological rules generating lexical phonological phenomena. These rules govern permissible correspondences between the form of entries listed in the dictionary and the form they develop when they are combined in sequences of morphemes.These files are used both for analysis and generation. The process of the present morphological analysis consists of parsing an input of inflected words with respect to the word grammar. Stems associated to the appropriate morpho-syntactic information will be the output of the parsing.
