Problem-solving methods are ready-made software components that can be assembled with domain knowledge bases to create application systems. Ontologies and problem-solving methods have a long history of intricate relationships. In this chapter, we describe these relationships and how they can be used in a principled manner to construct knowledge systems. We have developed a methodology that stro...

We develop a new methodology and tool for knowledge acquisition under uncertainty. A new knowledge representation called Bayesian Knowledge Bases provides a powerful key to our approach and is well-grounded in probability theory. In this paper, we demonstrate the ease and flexibility with which knowledge acquisition can be accomplished while ensuring the consistency of the knowledge base as dat...

We propose a methodology for enhancing domain knowledge bases through natural language text understanding. The acquisition of previously unknown concepts is based on the assessment of the \quality" of linguistic and conceptual evidence underlying the generation and reenement of concept hypotheses. Text understanding and concept learning are both grounded on a terminological knowledge representa...

Abstract—Healthcare safety has been perceived important. It is essential to prevent troubles in healthcare processes for healthcare safety. Trouble prevention is based on trouble prediction using accumulated knowledge on processes, troubles, and countermeasures. However, information on troubles has not been accumulated in hospitals in the appropriate structure, and it has not been utilized effe...

BACKGROUND Exercise training within the pulmonary rehabilitation (PR) context is considered the most effective strategy to reduce COPD symptoms. However, participation in PR and continued exercise training following program completion are low. Previous research examined factors related to attendance and adherence, but the knowledge base to date has been limited to quantitative findings that foc...

Evidence-based nursing is central to the knowledge base for nursing practice. Critics of evidence-based nursing dislike the central role that randomized controlled trials (RCTs) take in providing evidence for nursing, claiming that the context and experience of nursing care are removed from evaluation. Many nursing decisions involve questions regarding the effectiveness of interventions, best e...
