In a rather sharp departure from more orthodox lines of introspective acquisition of structural data on meaning and knowledge representation in cognitive science an empirical approach IS explored that analyses natural language data statistically represents its numerical findings fuzzy-set theoretically and interprets its intermediate constructs stereotype meaning points topologically as elements of semantic space. As connotative meaning representations these elements allow an aspect-control 1ed con-tents-driven algorithm to operate which reorganizes them dynamically in dispositional dependency structures DDS-trees which constitute a procedurally defined meaning representation format. 0. Introduction Modelling system structures of word meanings and or world knowledge is to face the problem of their mutual and complex relatedness. As the cognitive principles underlying these structures are poorly understood yet the work of psychologists Al-re-searchers and linguists active in that field appears to be determined by the respective discipline s general line of approach rather than by consequences drawn from these approaches intersecting results in their common field of interest. In linguistic semantics cognitive psychology and knowledge representation most of the necessary data concerning lexical semantic and or external world information is still provided 1ntrospectively. Researchers are exploring or make test-persons explore their own linguistic cognitive capacities and memory structures to depict their findings
