Imperfect Knowledge Management (IKM) in GEFRED (GENeralized model for Fuzzy RElational Databases)
Imperfect Knowledge Management (IKM) aids in managing imprecise, uncertain, or incomplete aspects of meaning. IKM acknowledges that an enterprise's knowledge is often imperfect, characterized by varying degrees of imprecision, uncertainty, or incompleteness. In this context, knowledge is viewed as an object described by attributes and values. Our focus is on the domain of competencies (know how) in the production of coated cardboard, particularly the process of converting finished products from the manufactured cardboard. This process involves both classic and fuzzy attributes that are used to assess the quality of the cardboard. This article introduces a set of protocols designed to model a fuzzy metaknowledge base using GEFRED (GENeralized model for Fuzzy RElational Databases) in an Oracle 8i relational database system.
