Hedge A hedge is a one-input truth value manipulation operation. It modifies the shape of the truth function, in a manner analogous to the function of adjectives and adverbs in English. Some examples that are commonly seen in the literature are intensifiers like "very", detensifiers like "somewhat", and complementizers like "not". One might define "very x" as the square of the truth value of x, and define "somewhat x" as the square root of the truth value of x. Then you can make fuzzy logic statements like: y is very low which would evaluate to (y is low) * (y is low). One can think of "not x" as being a hedge in the same sense, defining "not x" as one minus the truth value of x. ================================================================Go Back Up
