Tile present article examines hyponymy as an example of paradigmatic relation and restriction relation as a syntagmatic relation. The theoretical results of their implementation are illustrated. For both relations the paper presents the different procedures by which they are automatically recognized and extracted from the natural language definitions the degree of reliability of their automatic labeling the use of these labels in interactive queries on the lexical data base and finally the theoretical results of their implementation in a Machine-Dictionary. II THE LANGUAGE OF DEFINITIONS AS A SUBLANGUAGE I INTRODUCTION In previous papers it has been pointed OUL that in a we 11-structured Lexical Data Base it becomes possible to detect- automatically and to evidence through interactive queries a number of morphologies 1 syntactic or semantic relationships between lexical entries such ils synonymy hyponymy. hyperonymy. derivation case-argument lexical field etc. The present article examines hyponymy as an example of paradigmatic relation and what can be called restriction or modification relation as a syntagmatic relation. By restriction or modification relation. I mean that part of a so-called ar is tote 11 an definition which has the function of linking the genus and the differentia specifica . When evidenced in a lexicon the hyponymy relation produces hierarchical trees partitioning the lexicon in many semantically coherent subsets. These trees arc not created once and for all but it is important that they are procedurally activated at the query moment. While evidencing the second relation considered one can investigate as to whether it is .
