Lexical-semantic Conversions in the Valency Lexicon
Kettnerová, Václava ; Lopatková, Markéta (advisor) ; Panevová, Jarmila (referee) ; Karlík, Petr (referee)
In this thesis, we provide an adequate lexicographic representation of lexical-semantic conversion. Under the term lexical-semantic conversion, the relation between semantically similar syntactic structures which are based on separate lexical units of the same verb lexeme is understood. These relations are associated with various changes in valency structure of verbs - they may involve a number of valency complementations, their type, obligatoriness as well as morphemic forms. These changes arise from differences in the mapping of situational participants onto valency complementations. On the basis of semantic and syntactic analysis of two types of Czech lexical- semantic conversions, the locative conversion and the conversion Bearer of action-Location, we propose to represent lexical units creating syntactic variants in the relation of lexical semantic conversion by separate valency frames stored in the data component of the lexicon. The special attribute -conv whose value is a type of lexical-semantic conversion is assigned to relevant valency frames. Then the rule component of the lexicon consists of general rules determining changes in the correspondence between situational participants and valency complementations. This proposal is primarily designed for the valency lexicon of Czech verbs, VALLEX....
