Discusses the development of phraseological machine translation based on the theory that in natural languages, phraseological units cannot always be reduced to words. Describes the phraseological translation process of computer software and machine dictionary systems that translate Russian into English and English into Russian. (JMV)

Examines the relationship between users' expertise, task complexity of information system use, and artificial intelligence to provide the basis for a conceptual framework for considering the role that artificial intelligence might play in information systems. Cognitive and conceptual models are discussed, and cost effectiveness is considered. (27…

A hypertext-based thesaurus is proposed as a navigational aid to the subject domain of a bibliographic database. Implementation of a hypertext version of the "Thesaurus of ERIC Descriptors" with database linking strategies is discussed. (44 references) (EA)

Discusses the design of computer applications, focusing on understanding design representations--what makes design representations work, and how, in different contexts. Examines the place of various types of representation (e.g., formal notations, models, prototypes, scenarios, and mock-ups) in design and the role of formalisms and representations…

In the early 1990s, numerous academic libraries adopted the web as a communication tool with users. The literature on academic library websites includes research on both design and navigation. Early studies typically focused on design characteristics, since websites initially merely provided information on the services and collections available in…

This paper will present a review of design-based research conducted over the past 10 years that has modeled and promoted students' reasoning, conceptual change and argumentative dialogue processes and practices through designing a number of digital dialogue games. This line of work was inspired by some challenges and insights that emerged during…

Increasingly, machine learning is entertained as a mechanism for improving the efficiency of planning systems. Research in this area has generated an impressive battery of techniques and a growing body of empirical successes. Unfortunately the formal properties of these systems are not well understood. This is highlighted by a growing corpus of…

Reviews literature on digital libraries (DLs) by examining its conceptions; concepts related to social informatics; researchers exploring DL social informatics; methods of DL design; social aspects of DL infrastructure and use; and research approaches to DL social informatics. Presents questions for further research and discusses social and…

Presents a conceptual overview of online information systems, emphasizing the distinction between hypertext (associative) and more traditional (search) models of information management. Five commercially available hypertext systems are reviewed, hypertext design issues are discussed, and the application of structured writing techniques to…

Describes a comparative study of the "help" facilities of 16 interactive information retrieval systems. Guidelines for the design of a "help" facility are presented and then used to evaluate the quality and friendliness of each system. Suggestions for the improvement of online "help" facilities are discussed. (31…

Discussion of intelligent computer-assisted instruction (ICAI) systems focuses on tutorial strategies. Highlights include artificial intelligence; degree of learner control; student modeling requirements in ICAI; ICAI system architecture; forms of knowledge; and tutoring functions, including questioning, teaching, and motivating. (17 references)…

Explores the use of visualization to enhance the information retrieval process, particularly in bibliographic retrieval systems. Topics discussed include document retrieval systems; human visualization; the VIBE (VIsualization by Example) system, a prototype system for visualizing a collection of documents; and differences between VIBE and more…

Describes the design of an experimental computer-aided cataloging advisor, Mapper, that was developed to help novice users with the descriptive cataloging of single-sheet maps from U.S. publishers. The human-computer interface is considered, the use of HyperCard is discussed, the knowledge base is explained, and assistance screens are described.…

Presents evidence to show that the body plays a continuing and fundamental part in the process of thinking and the development of the knowledge used to think. Topics discussed include knowledge structures and representations; artificial intelligence; feeling; learning processes; models of knowledge; information retrieval; and implications for…

Examines the functional characteristics of intelligent computer-assisted instruction (ICAI), proposes a structural model that defines expertise requirements for the development of an ICAI system, and discusses the requirements of a multidisciplinary cooperative effort for its development. Knowledge acquisition, learning needs, and instructional…
