Focuses on the user and human-computer interaction aspects of the research based on the Okapi text retrieval system. Three experiments implementing different approaches to query expansion are described, including the use of graphical user interfaces with different windowing techniques. (Author/LRW)

Discussion of information architecture focuses on a model of information interaction that bridges the gap between human and computer and between information behavior and information retrieval. Illustrates how the process of information interaction is affected by the user, the system, and the content. (Contains 93 references.) (LRW)

Includes three articles that discuss activity theory, based on "Context and Consciousness." Topics include human-computer interaction; computer interfaces; hierarchical structuring; mediation; contradictions and development; failure analysis; and designing educational technology. (LRW)

The Oklahoma Association of Teacher Educators 2009 Journal includes the following four peer reviewed articles: (1) The Changing Role of Grandparents (Fred D. Hammond, III, Terry E. Spigner, Charolette Myles-Nixon, and Pauline Holloway); (2) Pedagogical Agent Instructional Design Challenges (Jon Martens); (3) Differences in Relatedness across…

One common objective of instructional multimedia products is enhancement of learning. It follows that one of the primary tasks of the interface designer is the creation of a user-interface that is motivating, interactive, intuitive and at the same time imposing as minimal as possible a cognitive load on the learner. To achieve this goal, qualities…

Natural language processing (NLP) is concerned with getting computers to do useful things with natural language. Major applications include machine translation, text generation, information retrieval, and natural language interfaces. Reviews important developments since 1987 that have led to advances in NLP; current NLP applications; and problems…

Identifies user interface problems as they relate to computer-assisted instruction (CAI); reviews the learning theories and instructional theories related to CAI user interface; and presents potential CAI user interface improvements for research and development based on learning and instructional theory. Focuses on screen design improvements.…

Discusses the interaction between students and technology in online open learning distance education courses. Topics include human-computer interfaces; relationships between course design and learning theories; how students use computer technology and how it can help them learn; and a new framework for evaluating an online open learning course.…

Assesses the appropriateness of GUIs (graphical user interfaces), more specifically Windows-based interfaces for CD-ROM. An evaluation model is described that was developed to carry out an expert evaluation of the interfaces of seven CD-ROM products. Results are discussed in light of HCI (human-computer interaction) usability criteria and design…

Focuses on human behavior in the information-seeking process, and identifies behaviors influencing the design of information retrieval system interfaces. Discusses the principles of saturation, concreteness, least resistance, familiarity, stimulation, certainty, simplicity, and following-form. (PEN)

Discusses human/computer interaction research, human/computer interface, and their relationships to information literacy. Highlights include communication models; cognitive perspectives; task analysis; theory of action; problem solving; instructional design considerations; and a suggestion that human/information interface may be a more appropriate…

Reviews several mechanisms to support navigation in hypertext following a brief discussion of the phenomena of disorientation in hyperspace. Categorizes ways to support navigation in terms of the following: solutions regarding the tools to support navigation; solutions regarding interface and navigation metaphors; and solutions regarding hardware…

This paper describes an evaluation of the Kea automatic keyphrase extraction algorithm. Tools that automatically identify keyphrases are desirable because document keyphrases have numerous applications in digital library systems, but are costly and time consuming to manually assign. Keyphrase extraction algorithms are usually evaluated by…

Explains MOOsburg, a community-oriented MOO that models the geography of the town of Blacksburg, Virginia and is designed to be used by local residents. Highlights include the software architecture; client-server communication; spatial database; user interface; interaction; map-based navigation; application development; and future plans. (LRW)

This paper presents new web-based educational software (webNetPro) for "Linear Network Programming." It includes many algorithms for "Network Optimization" problems, such as shortest path problems, minimum spanning tree problems, maximum flow problems and other search algorithms. Therefore, webNetPro can assist the teaching process of courses such…
