Academic Profile

I have a Master of Applied Science in Information Studies from Charles Sturt University - Riverina and a Bachelor of Business majoring in Computing and Management Information Systems (MIS) from Charles Sturt University - Mitchell. I completed these studies whilst working in the computer industry since 1980 in roles ranging from operator to analyst/programmer to manager and consultant.

My Masters Degree thesis "The Adaptation of Traditional Expert Systems to Provide 'What-If' Processing in the Decision Support System Style" developed an approach to changing the system style of an existing ES from consultation mode to a more exploratory and user-controlled mode without alteration to the domain knowledge. The approach was developed and tested on AusVit, a viticulture (grape production) expert system which advises vineyard managers on what course of action should be taken regarding various pests and diseases. The study suggests that one knowledge base can support a range of interaction styles, effectively reusing the knowledge and making it a more valuable resource.

Under the supervision of Prof. Paul Compton at the University of New South Wales, my PhD research carried on from this idea by considering how knowledge which was captured for such purposes as consultation may be reused to to allow alternative uses such as causal modelling, tutoring, explanation or critiquing. More specifically I looked at how to reuse knowledge bases(KB) built by a knowledge acquisition technique known as Ripple Down Rules (RDR). I looked at the compaction of RDR KB to remove repetition and improve the clarity of the KB for such tasks as explanation and how rough sets (Pawlak 1991) may be used to verify and validate KBS and find dependencies between attributes, values, rules and conclusions. My main offering was the ability to automatically generate a terminological KBS (in the form of an abstraction hierarchy) from the RDR assertional KBS using Formal Concept Analysis (Wille 1982). Starting with assertions and retrospectively generating an ontology avoided the problems associated with capturing and validating models since RDR is a simple, case-based KA technique that allows assertions to be acquired, maintained and validated directly by domain experts.
