Domain Limitations And Interface Requirements For Expert Developed Knowledge Based Systems, Bernard Lee Lewis
Domain Limitations And Interface Requirements For Expert Developed Knowledge Based Systems, Bernard Lee Lewis
Engineering Management & Systems Engineering Theses & Dissertations
The expanded use of graphical, case-based and object oriented techniques in expert systems creation has made it more practical for domain experts to develop their own applications. This thesis focuses on the elements necessary in an expert/developer interface and looks at various forms and techniques that exemplify such an approach. The spreadsheet metaphor is used for an interface or managed set of interfaces that a domain expert can use in building his own expert system or prototype. criteria are established for such interfaces and recent commercial offerings that make expert-created knowledge-bases more practical are reviewed for techniques that qualify. Approaches …
Effectiveness Analysis Of Knowledge Bases, Shensheng Zhao
Effectiveness Analysis Of Knowledge Bases, Shensheng Zhao
Computer Science Theses & Dissertations
Knowledge base systems (expert systems) are entering a critical stage as interest spreads from university research to practical applications. If knowledge base systems are to withstand this transition, special attention must be paid to checking their effectiveness. The issue of effectiveness analysis of knowledge base systems has been largely ignored and few works have been published in this field. This dissertation shows how the effectiveness of a knowledge base system can be defined, discussed and analyzed at the knowledge base system level and the knowledge base level. We characterize the effectiveness of a knowledge base system in terms of minimality, …
