| summary | The topic of this presentation is the global structure of natural language lexicons and of their formal representation. More precisely, I will question the overall geometric organization of lexical models (linear textual models such as dictionaries, hierarchical taxonomies, multidimensional networks, ...). I will first examine the general problem of representing lexical knowledge, highlighting the importance of adopting a geometric metaphor for lexicons that is suitable for lexicology and its applications. This leads to the specification of the very nature of lexicons that have to undergo geometrization by reanalyzing the overused notion of mental lexicon. Two instances of mental lexicons will be distinguished – the logical lexicon vs. the physiological lexicon –, identifying the former as the actual object of study of lexicology and lexicography. After examining the most common metaphors of the logical lexicon, I present Lexical Systems: formal lexical models whose structural backbone is based on Meaning-Text lexical functions. |
