We discuss an environment that permits flexible modeling and fuzzy querying of complex data and knowledge including uncertainty. With such an environment, one can have intelligent retrieval of information from knowledge- intensive applications. In this study, we specifically describe the details (the model, inference mechanism, etc,) of the fuzzy knowledge base system (coupled with a fuzzy object-oriented database system, namely FOOD) of this environment.
