An artificial intelligence approach to the design of online information retrieval systems by Hsinchun Chen( )
1 edition published in 1990 in English and held by 2 WorldCat member libraries worldwide
In this thesis we adopt an artificial intelligence approach in investigating the online information retrieval activity and in studying the design of online information retrieval systems. Our initial approach was to investigate the interactions between the searcher and the retrieval system, and the searcher and the reference librarian. Our objective was to develop cognitive models of these processes that will provide a sound basis for incorporating search assistance into an online system

A Knowledge-Based Model of Audit Risk by Vasant Dhar( )
1 edition published in 1988 in English and held by 1 WorldCat member library worldwide
Within the academic and professional auditing communities, there has been growing concern about how to accurately assess the various risks associated with performing an audit. These risks are difficult to conceptualize in terms of numeric estimates. This article discusses the development of a prototype computational model (computer program) that assesses one of the major audit risks -- inherent risk. This program bases most of its inferencing activities on a qualitative model of a typical business enterprise
Pattern discovery and simulation methods for evaluating risk control strategies in futures trading systems by Roger M Stein( )
1 edition published in 2000 in English and held by 1 WorldCat member library worldwide
The contributions of this research are threefold. First I provide a comprehensive framework for conducting simulation experiments and analyzing the results using data mining and OLAP techniques. Second, I demonstrate that risk control strategies can be beneficial to traders, but that they are only effective in certain situations and that in general they cannot convert an unfavorable trading strategy into a favorable one. I provide heuristic guidance, based on system performance statistics, for identifying situations where the noise levels in trading systems indicate that stops can be beneficial. Third, I demonstrate that information about the recent market behavior can be useful in determining optimal information about the recent market behavior can be useful in determining optimal stop and profit target levels
A knowledge representation for constraint satisfaction problems by Albert E Croker( Book )

Heuristics to support constraint-based model formulation and analysis by Padmanabhan Ranganathan( Book )
1 edition published in 1994 in English and held by 1 WorldCat member library worldwide
There are, however, no theories or guidelines specifying when such strategies should be applied in order to derive information that a model builder or user might find useful, or that would answer specific queries. Rather, designers and analysts continue to write customized programs for analyzing their designs or models in a trial and error fashion
Coordination and control in distributed work: Towards intelligent design by Hardeep Singh Johar( Book )
1 edition published in 1994 in English and held by 1 WorldCat member library worldwide
The issue of knowledge representation is addressed by designing a shared memory that provides a group context for individual action, and adheres to the organizational principle of responsibility. The shared memory is an extension of the artificial intelligence system, assumption based truth maintenance system. The shared memory and the active role elements are then combined into an architecture for supporting the two stakeholders in design. As a proof of concept we implement a prototype coordination support system
A value-chain based process model for supporting business process reengineering by Vasant Dhar( Book )

Multiple agent formalisms for coordination in organizational problems by Hardeep Johar( Book )

The relationship between earnings events and returns: A comparison of four nonlinear prediction models by Dashin Chou( )
1 edition published in 1999 in English and held by 1 WorldCat member library worldwide
Finally, we applied the most accurate prediction model, that based on GA, to implement a systematic trading strategy. Since the GA's patterns are rules, it is possible to interpret them. This is a major advantage of GA over other methods. Furthermore, we compared the 20-day return of the combined long rule from GA with the benchmark, 20-day return of SP500 index. The statistical results reject the null hypothesis that the 20-day return of the long strategies is NOT better than the benchmark
