An Experiment On Synthesis Of Russian Parametric Constructions

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. 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.
