Linguistic knowledge acquisition system on facial caricature drawing system

In this paper, a data oriented linguistic knowledge acquisition system which should obtain linguistic expressions for facial caricature is discussed. That acquisition process was made upon a framework of linguistic-based facial caricature-drawing system. Human knowledge nature is too complicated to implement on computers. Thus, we need a lot of approximation techniques. Fuzzy sets could act as magic cloak of simplicity for ambiguity and complexity of human thinking process. When fuzzy set is used for an instance of linguistic words, it might have complicated extents instead of simple Cartesian product form on multidimensional space. This paper introduced a knowledge acquisition system to obtain fuzzy set in nonsimplified form. It could get some result of linguistic instance, "frightening face" Linguistic knowledge has still complicated extent.
