摘要:

AbstractThis paper describes the concepts which allow an expert system to be used for both design diagnosis and design synthesis. An example of the implementation of these concepts is presented in the domain of preliminary design of domestic kitchens in the expert system PREDIKT. PREDIKT carries out both design diagnosis and design synthesis using the same knowledge base and utilises an existing expert system shell which has forward‐ and backward‐chaining capabilities. The significance of graphical interaction with expert systems in design domains is demonstra

摘要:

AbstractThis is the second part of a report which looks at expert systems and the man‐machine interface (mmi). The term ‘mmi’ is interpreted in a fairly broad sense to include knowledge acquisition and cognitive aspects of the user interface. Part One of the report (published in the previous issue of Expert Systems) examines what is currently happening in the area of knowledge acquisition in Britain and asks whether it really is the major bottleneck in the production of expert systems.Part Two of the report looks at cognitive aspects of the user interface, including dialogue control, explanation facilities, user models, natural language processing and the effects of new technology. It also considers the very important question of evaluation. Again the report is concerned with what is actually happening in these areas in Britain

摘要:

AbstractExpert systems are becoming increasingly complex and diverse. The need for efficient data management for their growing knowledge bases is apparent. Moreover, with the widespread use of Database Management Systems, the operational data required by the expert system is often already available from an online database. Hence the interaction of expert systems and databases is a topic which is receiving increasing attention. This paper reviews existing techniques for such interaction and describes a novel dictionary–driven approach to the problem, called a Dictionary Interface for Expert Systems and Databases (Difead). A prototype of Difead is described, which couples a Medical Diagnosis System, written in Lisp, with a relational databas

摘要:

AbstractThe purpose of knowledge representation for an expert system is to specify functions to be performed by the system. In this paper, a knowledge representation scheme which mutually combines procedures, functions, production rules and Horn clauses is outlined. Its knowledge representation model is an imaginary organisation for performing functions of a target system, where a number of members try to solve given problems systematically. Knowledge is distributed to each of the members with considerable modularity. Functional specification of expert systems would be performed with less difficulty.
