Two statistical models for estimating search time have been developed for the CA Condensates data base using the University of Georgia Text Search System. Comparative timings between the Chemical Abstracts Service search program and the University of Georgia search program are made for the Ca Condensates data base. (5 references) (Author/NH)

Recommends use of entries from the information retrieval diary of Ted Crump, expert technical translator at the National Institute of Health, in the construction of computer models showing how expert translators solve problems of ambiguity in language. Expert and inexpert translation systems, eponyms, abbreviations, and alphabetic solutions are…

This proceedings from the 2003 Symposium on Applications and the Internet (SAINT) contains papers from sessions on: (1) mobile Internet, including a target-driven cache replacement policy, context-awareness for service discovery, and XML transformation; (2) collaboration technology I, including human-network-based filtering, virtual collaboration…

Examines traditional and interactive models that have emerged in information retrieval (IR), and proposes an interactive IR model based on different levels in the interactive processes. Analyzes strengths and weaknesses of the traditional model. Concludes with general remarks on the state of IR interaction research. (Author/AEF)

A transformational model offers a way to eliminate the middleman (programmer) in acccessing a computerized data base. It provides a basis for the algorithms which analyze the input query. The linguistic analysis of the sentence string is translated into system terms and the required operations are carried out. (28 references) (Author/NH)

A future, automated, interactive, knowledge delivery system for use by researchers was tested using a manual cognitive model. Conceptualized from schema/frame/script theories in cognitive psychology and artificial intelligence, this hypothetical system was simulated by two psychologists who interacted with four researchers in microbiology to…

The Voice Interactive Analysis System study continued research and development of the LISTEN real-time, minicomputer based connected speech recognition system, within NAVTRAEQUIPCEN'S program of developing automatic speech technology in support of training. An attempt was made to identify the most effective features detected by the TTI-500 model…

Discusses the problem of establishing terminology for mental models, attempts to sort out the various meanings found in the literature, and offers definitions that could help in developing a more standardized terminology for discussing issues of concern to researchers in human-computer interaction. The role of mental models in learning and using…

Organized from the viewpoint of information retrieval theory, this review addresses issues of chemical information representation, comparison and matching, and retrieval strategies. Additional topics include similarity and clustering, visualization, and molecular diversity. Trends in research and application are identified, and gaps in the…

This report describes the development of a design and a small working model for a system for teaching and assisting in the performance of bibliographic on-line searches through the use of an intermediary computer. The system in its present form is intended for direct users of scientific and technical information systems. However, it is felt that…

The objectives of the study presented in the dissertation were to identify present and anticipated information requirements of the various departments within the Oklahoma State Department of Vocational and Technical Education, to design a computerized information system model utilizing an integrated systems concept to meet information…

The aim of the Automated Retrieval Information System to Track and Optimize the Training and Learning Environment (ARISTOTLE) project is to develop a computer-based training model to link program standards, tests, resources, curriculum, and operational and student placement procedures of the Canada Manpower Centers, the Ministry of Colleges and…

Society and education are changing rapidly, and since computers are playing a significant role in these changes it is imperative that secondary school teachers become more fully informed about computers. Computers are of interest to learners because they have led to new theoretical developments, such as automata theory, have many practical…

Discusses the traditional Cranfield model for information retrieval (IR) evaluation, problems with the model, and extensions and alternatives to Cranfield; describes emerging themes in IR evaluation, including multiple evaluation dimensions and methods, inclusion of users and other stakeholders in the evaluation process, and various approaches to…

The paper examines in depth administrative and instructional uses of the computer in adult education. The author demonstrates: (1) positive findings related to the feasible use of the computer in data analyses and report writing for administrative purposes, and (2) preliminary, yet encouraging, findings in the area of computer managed instruction…
