In AI and other branches of Computer Science expert models are often studied and used. Here we examine experts which evaluate formulas of modal logic. An expert model consists of a set of experts and a domination relation which dictates how each expert’s opinion is dependent upon the opinions expressed by other experts. Such multiple-expert modal models were introduced and investigated by Fitti...

This paper investigates optimal portfolio strategies in a market where the drift is driven by an unobserved Markov chain. Information on the state of this chain is obtained from stock prices and expert opinions in the form of signals at random discrete time points. As in Frey et al. (2012), Int. J. Theor. Appl. Finance, 15, No. 1, we use stochastic filtering to transform the original problem in...

Conducting presentations with bidirectional communication requires extended presentation systems with sophisticated expressions and real-time feedback gathering. We aim to develop an interactive presentation system to enhance presentations with bidirectional communication during presentations. We employed a hybrid approach of a traditional presentation supporting system (PowerPoint) and a Web a...

This paper describes a normative system design that incorporates diagnosis, dynamic evolution, decision making; and information gathering. A single influence diagram demonstrates the design's coherence, yet each activity is more effectively modeled and evaluated separately. Application to offshore oil platforms illustrates the design. For this application, the normative system is embedded in a ...

In this paper we discuss a semantics for translating natural language statements into facts of an underlying expert system, replacing the more conventional menu interface for gathering data from the user. We describe two issues that must be considered when building such an interface for an expert system. These issues are semantic processing of the user statements and the design of an interprete...

OBJECTIVE To introduce a fuzzy linguistic model for evaluating the risk of neonatal death. METHODS The study is based on the fuzziness of the variables newborn birth weight and gestational age at delivery. The inference used was Mamdani's method. Neonatologists were interviewed to estimate the risk of neonatal death under certain conditions and to allow comparing their opinions and the model ...
