Abstract
The goal of knowledge engineers is to develop expert systems to help non-experts solve problems ordinarily requiring human expertise. An integral part of knowledge engineering is determining how to help experts articulate their expertise. In spite of decades of research however. there is no well-defined or universally accepted method of knowledge engineering. This thesis has introduced an approach to knowledge engineering for eliciting nursing knowledge. The domain of pressure ulcer prevention and management knowledge was selected, elicited and represented in a conceptual model. The part of the conceptual model representing pressure ulcer prevention knowledge was used as the basis of an implementation model, then incorporated onto VPExpert's TM expert system shell in the form of IF-THEN statements.
