Summary: Query answering requirements for a knowledge-based treatment of user requests led us to introduce the concept of closure of an intuitionistic fuzzy set over a universe that has a hierarchical structure. We recommend the automatic analysis of queries according to concepts defined as part of knowledge-based hierarchies to guide the query answering as part of an integrated database environment with the aid of hierarchical intuitionistic fuzzy sets (H-IFS). In this paper, based on the notion of H-IFS, we propose an ad hoc utility built on top of Oracle10g that allows us to enhance the query capabilities by providing better, knowledgeable, and optimized answers to user’s requests.
