Discusses intelligent filtering systems and describes work in the INFOS (Intelligent News Filtering Organizational System) project designed to automatically categorize data as relevant or irrelevant based on user interests. The filtering is performed by combining keyword-based hill climbing, knowledge-based conceptual representation via WordNet,…

Presents an overview of the growth of work in Human-Computer Interaction (HCI) over the last 40 years. Notes formative influences and contributing disciplines and discusses technology, applied problems, and the design for usability. Outlines issues that pose problems for HCI in the near future. Seven figures show growth in media. (141 references)…

Insertion of computer technology in existing school buildings requires leadership at the district level, careful planning to provide properly located and sized support space, and a media backbone that will serve for a long time. The architect must design in flexibility for connection of hardware applications that are still being developed. (MLF)

Reviews the literature on the development of full-text electronic libraries in the academic setting. Organizational factors can have impact on electronic library development and ultimate usability. Topics include strategic management, planning and implementation; system specification and design; document provision; user support and training; and…

Discusses the interlibrary loan (ILL) protocol, a standard based on the principles of the Open Systems Interconnection (OSI) Reference Model. Benefits derived from protocol use are described, the status of the protocol as an international standard is reviewed, and steps taken by the National Library of Canada to facilitate migration to an ILL…

A small school system can plan and install an effective computer system by developing a comprehensive plan; involving the personnel who will use the system; relying on vendors with proven records; and recognizing that training is an ongoing process. (MLF)

Describes a prototype interactive science catalog for children that will have three interfaces: a subject-oriented browsing search, a search tied directly to science simulations, and an author/title/subject keyword searchable interface. Research plans include examinations of children's abilities to formulate and implement searchable queries and…

Reports on design and rationale of Online Access to Knowledge, a computer intermediary developed by Online Access to Knowledge Project to enable users with little or no training or experience in bibliographic searching to conduct their own searches. Topics covered include software design, tutorials and assistance programs, and conclusions based on…

Discusses the use of hypertext for publishing and other document control activities in higher education. Topics discussed include a model of hypertext, called GUIDE, that is used at the University of Arizona Medical School; the increase in the number of scholarly publications; courseware development by faculty; and artificial intelligence.
