Expert systems are computer programs which incorporate artificial intelligence technology and are created to emulate the decision-making abilities of human experts. The advantage of such systems lies in their ability to capture and model expert problem solving knowledge in a domain and make it available to an unlimited number of consumers in an economic and efficient way. The purpose of this pr...

techniques for expert system knowledge acquisition based on the techniques that were successfilly used to develop the Central Office Maintenance Printout Analysis and Suggestion System (COMPASS) Knowledge acquisition is not a science, and expert system developers and experts must tailor their methodologies to fit their situation and the people involved. Developers of future expert systems shoul...

Expert-based estimation is the most common and preferred method to estimate the effort for software development project because it is fast, less expensive and reasonably accuracy. Expert software developers use his intuition and experience during effort estimation task. Estimation by analogy of features is also used to compare the new feature to similar in past development. This paper extends r...

This project applies expert system technology to the task of searching online collections of documents . We are developing an intelligent search intermediary to help end-users locate relevant passages in large fulltext databases. Our expert system will automatically reformulate conte.xtual Boolean queries to improve search results and will present re~rieved passages in decreasing order of relev...

The purpose of this study was to develop a computerized exercise expert system (CEES) that creates tailored exercise plans for older adults. A panel of experts was selected in the areas of medicine, exercise physiology, health promotion, exercise psychology, and gerontology. The experts communicated with the principal investigator and the project members by mail, email, telephone, and expert me...

In this paper we compare estimates of the left-right positions of political parties derived from an expert survey recently completed by the authors with those derived by the Comparative Manifestos Project (CMP) from the content analysis of party manifestos. Having briefly described the expert survey, we first explore the substantive policy content of left and right in the expert survey estimate...

Industries in New York State and across the United States need to implement waste minimization programs. The highest priority for these management programs is the elimination and reduction of wastes, then, any waste which cannot be eliminated or reduced should be evaluated to determine if any recycling opportunities exist either onor off-site. Due to the complex interaction of production, proce...

Many techniques for representing knowledge have been proposed, but there have been few reports that compare their application This article presents an experimental comparison of four knowledge representation schemes: a simple production system, a structured production system, a frame system, and a logic system. We built four pilot expert systems to solve the same problem: risk management of a l...
