One sees a multitude of fuzzy AND and OR functionals. Hmmm, It sounds like adjectives are often specialized and need to have custom response to qualifiers and other modifiers. Sounds like an object-oriented class structure would help. The class structure could define how different sets respond to different modifiers. General rules and exceptions should be easy to build in.
Language is very hard to capture with a simple model.
I think an OO specification of fuzzy sets and methods is the most flexible way to go.
