Voice over Internet Protocol (VoIP) is becoming a reality in many organizations. The potential for mobility in voice over wi-fi networks will derive demand for the technology. Wireless VoIP is poised to rival VoIP as an alternative telephony tool. Internet has been used to transport data in the form of packet. In the past, Internet did not support…

Shortly after a researcher arrived at a Traditional Mohawk (Iroquois) Indian community in New York State in May 1997, seven community members began using the Netscape 3.0 e-mail system with steadily increasing frequency. The researcher was interested in studying the relationship between new communication technology and identity maintenance. E-mail…

Documents issues on and makes specific recommendations for adapting extant time-sharing systems for computer assisted instruction. (Authors/WM)

Proposes algorithmic method of searching and presents experimental data testing efficacy of using Boolean negation to eliminate redundancy and reduce cognitive strain of communication barrier at human-computer interface. Cognitive information processes, concept of Boolean NOT, and problem-solving behavior are explored. Twenty-five references are…

Outlines structural changes in the information supply community effected by the emergence of computer-searchable files as a major information resource together with other developments in electronic technology. Database definitions, interface differences, DuPont experiences, and options available to libraries and information centers are discussed.…

Michigan State University has now documented the energy savings that have accrued since 1975 when a central control system was first installed. (Author)

Examines electronic aids to translation both as ways to automate it and as an approach to solve problems resulting from shortage of qualified translators. Describes the limitations of robotic MT (Machine Translation) systems, viewing MAT (Machine-Aided Translation) as the only practical solution and the best vehicle for further automation. (MES)

Data from three graduate programs using advanced learning technologies (ALTs) identified important human factors issues in technology use in three categories: learners (needs, skills, support, and motivation related to ALTs); faculty (attitudes, skills, support, and motivation related to ALTs); and technical staff (methods of providing assistance,…

Examines various ways of dividing the labor of an information search between the person and the system. Different configurations of two dimensions--degree of system involvement in searching and types of search activity carried out by the person or system--are discussed. Recommendations for further research and development are offered. (49…

Describes an information system interface that allows specification of uncertain queries and combines evidence about the relevance of documents to produce an overall ranking. Results of an experiment that addressed some of the cognitive aspects of such an interface are also reported. (22 references) (Author/MES)

Describes the Case Hierarchy, a model of the case system of unconstrained natural language, and ways in which the case system is specialized in a restricted domain. Results of a feasibility study which examined the utility of the Case Hierarchy and the Case Hierarchy Tool (an intelligent editor supporting the domain analysis process) are…

As scientists seek to develop machines that can "learn," that is, solve problems by imitating the human brain, a gold mine of information on the processes of human learning is being discovered, expert systems are being improved, and human-machine interactions are being enhanced. (SK)

Presents a new model of searching in online and other information systems, and reviews the literature of manual information seeking behavior for suggestions of capabilities users might like in online systems. Based on the model--called "berrypicking"--and research, suggestions are made for how new search capabilities could be implemented…
