Integration of scientific data and formulae in an object-oriented knowledge-based system

摘要

An object-oriented knowledge based system has been developed to store and manipulate scientific knowledge in the form of data and formulae encountered in conventional textbooks on science and engineering. The formulae are input in the same form as they are written in, in terms of the well known symbols used by engineers and scientists. The system interprets the symbols as representing scientific quantities and links them with the underlying data and methods in the knowledge base. By linking data about scientific quantities with one or more appropriate formulae, it is shown that the knowledge base can be used for simple problem solving. The development of the system on a Sun Sparcstation was facilitated by the use of an object-oriented environment, Objectworks C++.
