Domain experts are skilled to build a narrow ontology that reflects their sub-field of expertise. It will be grounded on their work experience and personal beliefs. We call this type of ontology a single-viewpoint ontology. There can be a variety of such single viewpoint ontologies for a given domain that represent a wide spectrum of sub-fields and expert opinions on the domain. But to have a c...

The ability to model the evolution of software technology trends is valuable to many stakeholders in industry, academia, and government. Yet we often depend exclusively on the opinions of alleged experts to make predictions on trend evolution. In this paper we discuss an ongoing long term effort at bringing a measure of quantitative analysis to this discipline. We see our contributions as compl...

Before expert witnesses may testify in court, it is necessary that they be qualified to render an expert opinion. The qualification process has three steps: first, the expert’s training, education, experience, and other indices of qualification are elicited on direct examination by the retaining attorney. Second, a proffer is made to the court of the witness as an expert; the proffer may be cha...

We show how the transferable belief model (TBM) can be used to assess and to combine expert opinions. The transferable belief model has the advantage that it can handle weighted opinions and their aggregation without the introduction of any ad hoc methods. We also study a paradigm in reliability analysis. It shows that the TBM analysis leads to a solution diametrically opposed to the Bayesian s...

Expert systems are being used to solve accounting regulation problems. The tasks performed by these systems include developing financial statements, examining proxy statement information as in EDGAR (Electronic Data Gathering Analysis and Reporting), developing financial ratios from EDGAR and assisting in the computation of the provision for income tax for financial reporting. This paper discus...

This paper describes recent work on an ongoing project in medical diagnosis at the University of Guelph. A domain on which experts are not very good at pinpointing a single disease outcome is explored. On-line medical data is available over a relatively short period of time. Belief Functions (Dempster-Shafer theory) are first extracted from data and then modified with expert opinions. Several m...

Most conflicts in collaborative design are categorized as the problem of fuzzy multiple attributive group decision-making (FMAGDM). Both fuzzy assessments and the aggregation of multiple experts' opinions should be considered in the conflict resolution process. This paper presents a new approach for the problem, where cooperation degree (CD) and reliability degree (RD) are introduced for aggreg...
