Description morphosyntaxique et sémantique des adverbes figés en vue d‟un système d‟analyse automatique des textes grecs

Abstract : The object of this research is the systematic and formal description of Modern Greek fixed and semi-fixed adverbs, abbreviated here to fixed adverbs (i.e. κέζα ζηα άγξηα κεζάλπρηα/in the dead of night, ην κήλα πνπ δελ έρεη ΢άββαην/in a month of Sundays). Our goal is to obtain the most exhaustive and explicit description in the prospect of the automatic analysis of Greek language. Our framework is the Lexicon-Grammar methodology (M. Gross 1975, 1990a), based on the Transformational Grammar principles defined by Zellig S. Harris. This framework has provided us with an adequate model for the formal and systematic description of natural language. Our study is organised into five parts. The first part gives an overview of the two core notions present throughout our research: the notions of adverb and (fixed) multiword expression (MWE). In the second part, we study the lexical composition of 4,880 fixed adverbial forms, collected in printed and digital resources. In particular, we insist on the different types of variations and on the problems they raise in the representation of fixed adverbs in both morphological electronic dictionaries and lexicon-grammar tables. The third part is devoted to the syntactic and semantic analysis of fixed adverbs. In the first place, we distinguish fixed adverbs from complements which have identical forms but different syntactic behaviours. In the second place, we proceed to the syntactic analysis of simple sentences containing fixed adverbs or adverbs of date. The fourth part deals with the classification of fixed adverbs, classified into sixteen distinct morphosyntactic classes. We expose the theoretical principles of our classification operation and we describe how the lexicon-grammar tables of Greek fixed adverbs are organised. In addition, we present the classification criteria, the regularities and particularities of the classes established and the syntactic and semantic properties of fixed adverbs. The fifth part is dedicated to the exploitation of our linguistic data for Natural Language Processing (NLP) applications. Our interest is focused on the lexical recognition of fixed and semi-fixed adverbs in Greek texts. Representative samples of the fixed adverbs lexicon-grammar tables and the date expressions local grammar are illustrated in Appendix (volume 2).
