Toponymy, topology, topography of the semantic space
The toponymy of the semantic space - it actually has all the words of the language (see Toponymy in WIKIPEDIA)
Topography of semantic space studying boundaries as place names, and a knowledge of structures themselves, their forms, and searching for Zero-semantic domains.
The topology of the semantic space - the set of a knowledge structure with the properties of the homeomorphism and homotopy, regardless of their position in the semantic space. (This is one of their goals the creation of the theory, still unexplored part of the theory. Objectives: To identify types of such structures)
