Abstract :
A knowledge representation language Lk is introduced that is tailored for expressing the real-world meanings of stored data. Lk is developed to achieve a tight coupling between a knowledge base component and the database system. Lk offers (1) a flexible descriptive power which facilitates concepts to be expressed at different levels of granularity; (2) a versatile association mechanism which is capable of linking partially related concepts; and (3) a set of specialization and generalization operators that enable inexact reasoning in a heuristically controlled environment. Examples are provided to illustrate the language´s expressive power, its associability, and the inference operations. An example of processing an inference query is given to show the application of various utilities of Lk
