Representing problem-solving for knowledge refinement. (1999)
Conference Proceeding
CRAW, S. and BOSWELL, R. 1999. Representing problem-solving for knowledge refinement. In Proceedings of the 16th American Association for Artificial Intelligence national conference on artificial intelligence (AAAI-99), co-located with the 11th Annual conference on innovative applications of artificial intelligence (IAAI-99), 18-22 July 1999, Orlando, USA. Palo Alto: AAAI Press, pages 227-234.

Knowledge refinement tools seek to correct faulty knowledge based systems (KBSs) by identifying and repairing potentially faulty rules. The goal of the KrustWorks project is to provide a source of refinement components from which specialised refineme... Read More about Representing problem-solving for knowledge refinement..

Knowledge modelling for a generic refinement framework. (1999)
Journal Article
BOSWELL, R. and CRAW, S. 1999. Knowledge modelling for a generic refinement framework. Knowledge-based systems [online], 12(5-6), pages 317-325. Available from: https://doi.org/10.1016/S0950-7051(99)00018-0

Refinement tools assist with debugging the knowledge-based system (KBS), thus easing the well-known knowledge acquisition bottleneck, and the more recently recognised maintenance overhead. The existing refinement tools were developed for specific rul... Read More about Knowledge modelling for a generic refinement framework..

Refinement complements verification and validation. (1996)

Knowledge based systems are being applied in ever increasing numbers. The development of knowledge acquisition tools has eased the Knowledge Acquisition Bottleneck. More recently there has been a demand for mechanisms to assure the quality of knowled... Read More about Refinement complements verification and validation..

Refinement in response to validation. (1995)
Journal Article

Knowledge-based systems (KBSs) are being applied in ever increasing numbers. In parallel with the development of knowledge acquisition tools is the demand for mechanisms to assure their quality, particularly in safety critical applications. Quality a...

Consultant-2: pre- and post processing of machine learning applications. (1995)
Journal Article
SLEEMAN, D., RISSAKIS, M., CRAW, S., GRANER, N. and SHARMA, S., 1995. Consultant-2: pre- and post processing of machine learning applications. International journal of human computer studies [online], 43(1), pages 43-63. Available from: https://doi.org/10.1006/ijhc.1995.1035

The knowledge acquisition bottleneck in the development of large knowledge-based applications has not yet been resolved. One approach which has been advocated is the systematic use of Machine Learning (ML) techniques. However, ML technology poses dif...
