When observing the oppositness in multidimensional net of semantic relations demonstrated on Lexical Feature Maps (Self Organizing Maps, SOM), cooccurrence profiles extracted from the CCDB (IDS Mannheim) and their structure reveal that discourse-boundness of words is crucial. This model based on the cognitive, corpus-based attitude, can serve as a new design for lexical relations.

The organization of lexical feature maps points at the fact that lexical and encyclopedic knowledge is unevitably connected with paradigms in the SOM model based on cooccurrence profiles from which scalarity of discourse features can be elicited. Thus, visualising scalar structures anchored in usage and presented by organized cooccurrence profiles prove a meaning constituting/relativizing factor which highlights the problem of oppositness as well.

Consequently, a new horizon for corpus-driven lexicography opens up when describing oppositness in a framework of lexical relations.
