The paper describes an experimental model of syntactic structure generation starting from the limited fragment of semantics that deals with the quantitative values of object parameters. To present the input information the basic semantic units of four types are proposed:"object", "parameter", "function" and "constant". For the syntactic structure representation the system of syntactic components is used that combines the properties of the dependency and constituent systems: the syntactic components corresponding to wordforms and exocentric constituents are introduced and two basic subordinate relations ("actant" and "attributive") are claimed to be necessary. . | AN EXPERIMENT ON SYNTHESIS OP RUSSIAN PARAMETRIC CONSTRUCTIONS .

To present the input information the basic semantic units of four types are proposed object parameter function and constant . For the syntactic structure representation the system of syntactic components is used that combines the properties of the dependency and constituent systems the syntactic components corresponding to wordforms and exocentric constituents are introduced and two basic subordinate relations actant and attributive are claimed to be necessary. Special attention has been devoted to problems of complex correspondence between the semantic units and lexical-syntactic means In the process of synthesis such sections of the model as the lexicon the syntactic structure generation rules the set of syntactic restrictions and morphological operators are utilized to generate the considerable enough subset of Russian parametric constructions. 1 INTRODUCTION The semantics of Russian parametric constructions deals with the quantitative values of object parameters. The parametric information is more or less easily explicated by means of basic semantic units of four types object table boy parameter weight length age function more equal almost equal and constant two meters from 3 to 5 years . In simple situations each of these units is separately realized in a lexeme or a phrase their combinations forming full expressions with the given sense malchik vesit bolshe dvadcati kilogrammov boy weights more than twenty kilograms . It is precisely tiiese direct and simple means of expressions that are usually used in systems generating natural language texts. Natural languages however operate with more
