Two studies of the cognitive processes involved in online document-based information retrieval were conducted. These studies led to the development of five computational models of online document retrieval which were incorporated into the design of an "intelligent" document-based retrieval system. Both the system and the broader implications of…

Discussion of automated indexing techniques focuses on ways to statistically document improvements in the development of an automated keywording system over time. The system developed by the Joint Chiefs of Staff to automate the storage, categorization, and retrieval of information from military exercises is explained, and performance measures are…

Describes an intelligent tutor incorporating a program using artificial-intelligence planning methods to generate realistic audit files reporting actions of simulated users and intruders of a UNIX system, and a program simulating the system afterwards that asks students to inspect the audit and fix problems. Experiments show that students using…

Presents an intelligent computer-assisted language instruction (CALI) system called "Nihongo-CALI" (Japanese Computer Assisted Language Instruction), which employs natural language processing to provide immediate, grammatically sophisticated feedback to students in an interactive environment. The study compares the efficacy of this type…

Framed by theoretical and empirical research on cognitive and intelligent tutoring systems (ITSs), this commentary explores two areas. The first focuses on lack of conceptual clarity of the proposed constructivist stance and its related constructs. The second deals with similarities between the proposed stance and existing approaches documented in…

Provides an in-depth introduction to the various technologies that are bringing intelligent agents into the forefront of information technology, explaining how such agents work, the standards involved, and how agent-based applications can be developed. (Author/AEF)

Discusses the design and use of intelligent tutoring systems (ITS) for computerized business simulations. Reviews the use of ITS as an instructional technology; presents a model for ITS-based business simulations; examines the user interface and link between the ITS and simulation; and recommends expert-consultant diagnostic testing, and…

After decades of research in artificial intelligence (AI) and cognitive psychology, a number of companies have emerged that offer intelligent tutor system (ITS) soft ware to schools. These systems try to mimic the help that a human tutor would provide to an individual student, something nearly impossible for teachers to accomplish in the…

Web-based (or online) learning provides an unprecedented flexibility and convenience to both learners and instructors. However, large online classes relying on instructor-centered presentations could tend to isolate many learners. The size of these classes and the wide dispersion of the learners make it challenging for instructors to interact with…

In educational psychology research the concept "prior knowledge" is not always clearly described, but it is important to distinguish prior knowledge state (PKS) components as well as possible and to elucidate the relations among these elements. An in-case-study was conducted into the operationalizing of the concept of prior knowledge and…

This publication presents manuscripts and research reports by graduate students. Accompanying papers from their mentors establish a context for the student papers. In this volume the works are organized by the sponsoring university. Student papers presented are: (1) "How Will Moy, Chantale, Susan and Lola Make It through Art School?" (Miriam…

In machine learning there is considerable interest in techniques which improve planning ability. Initial investigations have identified a wide variety of techniques to address this issue. Progress has been hampered by the utility problem, a basic tradeoff between the benefit of learned knowledge and the cost to locate and apply relevant knowledge.…

This paper is a survey of publications on artificial neural networks published in business journals for the period ending July 1996. Its purpose is to identify and analyze trends in neural network research during that period. This paper shows which topics have been heavily researched, when these topics were researched, and how that research has…

A metaphor and ongoing debate of the information age is that the mind is a computer or that, conversely, the computer has a mind. Since the debate is conducted using anthropomorphic metaphors such as "intelligent,""memory," and "friendly" (terms from humanity), the language itself pressures the discussion towards the conclusion that computers will…

An in-progress interdisciplinary research effort, Conversation Analytic (CA) and Human-Computer Interaction (HCI) study, is reported. A conversation analytic approach to repair and self-explication is taken that covers both human studies and artificial intelligence. The term "human" is used here in place of "linguistic." Three…
