Phụ thuộc đơn điệu trong cơ sở dữ liệu mờ theo cách tiếp cận ngữ nghĩa lân cận của đại số gia tử

Fuzzy databases with linguistic data based on hedge algebras were introduced, where the evaluation of queries containing linguistic data was transformed into that of traditional queries. On this new viewpoint, in this paper a notion of linear functional dependencies in these databases will be defined reasonably. The problems related to increasingly and decreasingly linear functional dependencies will be considered.
