Context dependency of concepts in fuzzy logic

Fuzzy logic has attracted particular attention as being a tool for representing the meaning of vague terms. But it has been criticized because it neglects the effect of the surrounding context. Since the context can modify the meaning of a vague concept, fuzzy logic, without the effect of context, became isolated from its environment. To improve its effectiveness, the context dependency problem has to be resolved. We study context and contextual fuzziness, investigates some suggestions to solve the context dependency problem in fuzzy logic, along with their strong and weak points. We summarized important aspects of the context dependency notion. In the light of these clues that have to be taken into consideration, we are currently studying a structure where the context effect is taken into account. Without any doubt, this type of research will bring more enthusiastic engineering applications like intelligent human-machine interfaces
