摘要：One of the major unsolved problems in knowledge acquisition is reconciling knowledge originating from different sources. This paper proposes a technique for reconciling knowledge in two independent knowledge bases, describes a working program built to implement that technique, and discusses an exploratory study for validating the technique. The technique is based on the use of heuristics for identifying and resolving discrepancies between the knowledge bases. Each heuristic developed provides ...

摘要：Management is communication intensive and, therefore, managers may derive benefits from computer-based alternatives to the traditional communication modes of face-to-face (FTF), telephone, and written memo. This research examined the use of electronic messaging (EM) by ongoing management groups performing a cooperative task. By means of an in-depth multimethod case study of the editorial group of two daily newspapers, it examined the fit between the interactivity of the chosen communication mo...

摘要：There is a growing interest in the use of induction to develop a special class of expert systems known as inductive expert systems. Existing approaches to develop inductive expert systems do not attempt to maximize system value and may therefore be of limited use to firms We present an induction algorithm that seeks to develop inductive expert systems that maximize value. The task of developing an inductive expert system is looked upon as one of developing an optimal sequential information acq...

摘要：Rule-based expert systems deal with inexact reasoning through a variety of quasi-probabilistic methods, including the widely used subjective Bayesian (SB) and certainty factors (CF) models, versions of which are implemented in many commercial expert system shells. Previous research established that under certain independence assumptions, SB and CF are ordinally compatible: when used to compute the beliefs in several hypotheses of interest under the same set of circumstances, the hypothesis tha...

摘要：In this paper, we consider the problem of generating effective information gathering, communication, and decision-making (ICD) strategies for a distributed expert problem-solving (DEPS) system. We focus on the special case of a dual-processor DEPS system and present a decision-theoretic model that enables the characterization of feasible, efficient, and optimal ICD strategies. In view of the tremendous amount of computing needed to generate optimal strategies for problems of practical size, we...

摘要：Microcomputer and work-station technology is the latest wave in computing technology to influence day-to-day operations in business and government organization. Does sector affect adoption of this new information technology? If so, how? Utilizing the data from a large comparative national survey of data processing organizations, this proposition was examined. The results confirm that after controlling for other factors such as organizational size, experience with computer technology, current i...

摘要：The flow of manuscripts through the editorial offices of an academic journal can provide valuable information both about the performance of the journal as an instrument of its field and about the structure and evolution of the field itself. We undertook an analysis of the manuscripts submitted to the journal Information Systems Research (JSR) during its start-up years, 1987 through 1992, in an effort to provide a foundation for examining the performance of the journal, and to open a window on ...

摘要：Determining whether investments in information technology (IT) have an impact on firm performance has been and continues to be a major problem for information systems researchers and practitioners. Financial theory suggests that managers should make investment decisions that maximize the value of the firm. Using event-study methodology, we provide empirical evidence on the effect of announcements of IT investments on the market value of the firm for a sample of 97 IT investments from the finan...

摘要：Information technology is slowly becoming a part of educational classrooms and corporate training facilities. The current study examines the use and outcomes of computer-based instructional technology in the context of graduate business education. Case study data is gathered to explore how computer technology is used in the university classroom, and how computer-based teaching methods differ from traditional teaching methods in terms of class interaction and in-class learning. The study found ...

摘要：The value of mathematical modeling and analysis in the decision support context is well recognized. However, the complex and evolutionary nature of the modeling process has limited its widespread use. In this paper, we describe our work on knowledge-based tools which support the formulation and revision of mathematical programming models. In contrast to previous work on this topic, we base our work on an indepth empirical investigation of experienced modelers and present three results: (a) a m...
