Abstract:
|
|
|
The research is based on integrational approach to discourse, which consists of studying for discourse aspects: communicative, semantic, modal, relational. Within the integrational approach the emphasis is made on studying logical relations between judgments expressed by sentences. Three types of such relations have been distinguished: diachronic relation characterizing temporal succession of actions or states of the object, synchronic relation characterizing simultaneous features of the object, causative-consecutive relation based on syllogism. These relations form deep structure /relational aspect/ of discourse and correspond to three types of discourse: narration, description, reasoning. Logical relations between judgments may be manifested or not manifested in the surface structure of discourse /in its communicative aspect/. Sometimes the meaning of lexical and grammatical unites in the surface structure contradicts the nature of logical relations in textual deep structure. That is why to reveal logical relations between judgments in textual deep structure a special method is needed. Such method, developed in the dissertation, is called the method of compositional modeling. It includes four procedures: interpretation of nominative, modal, communicative aspects; reduction; normalization; canonization of the text. Application of these procedures makes it possible 1/ to reveal logical relations between judgments in textual deep structure, 2/ to make up a compositional model of the text. The compositional model of the text may perform the function of information retrieval, thus being a kind of a secondary source like the other secondary sources, such as abstracts.
