Harmon, Glynn – Information Processing and Management, 1984
Views information as residual or catalytic form of energy which regulates other forms of energy in natural and artificial systems. Parallel human information processing (production systems, algorithms, heuristics) and information measurement are discussed. Suggestions for future research in area of parallel information processing include a matrix…

Rau, Lisa F.; And Others – Information Processing and Management, 1989
Describes SCISOR (System for Conceptual Information Summarization, Organization and Retrieval), a prototype intelligent information retrieval system that extracts useful information from large bodies of text. It overcomes limitations of linguistic coverage by applying a text processing strategy that is tolerant of unknown words and gaps in…

Wong, Wai Yee Peter; Lee, Dik Lun – Information Processing and Management, 1993
Discussion of search strategies in information retrieval systems focuses on the implementation of document ranking based on inverted files. Highlights include descriptions of three heuristic methods for implementing a weighting strategy and a comparison of two methods for estimating retrieval accuracy, including document movement and linear…

Davies, Roy – Information Processing and Management, 1987
Discusses possibility of using expert systems to develop new model in cataloging theory made necessary by technological progress, rising user expectations, and economic pressures. A data structure for bibliographic information required by Anglo American Cataloging Rules, 2nd edition, (AACR2) is suggested, and possible heuristics for interpreting…

Croft, W. Bruce; Turtle, Howard R. – Information Processing and Management, 1993
Reports information retrieval experiments comparing the performance of a probabilistic retrieval model that incorporates interdocument links with the simpler spreading activation strategy. Results indicated that the overall improvement obtained by including hypertext links in the retrieval model was low. (30 references) (EA)

Rada, Roy; And Others – Information Processing and Management, 1993
Describes a collaborative, reuse hypertext system, called MUCH (Many Using and Creating Hypertext). The novel browsing and retrieval characteristics of the system are based on a semantic net connecting documents, thesauri, and discussions. Word patterns are documented for reuse, creating and reorganizing network traversal according to user…

Findler, Nicholas V.; And Others – Information Processing and Management, 1992
Describes SHRIF, a System for Heuristic Retrieval of Information and Facts, and the medical knowledge base that was used in its development. Highlights include design decisions; the user-machine interface, including the language processor; and the organization of the knowledge base in an artificial intelligence (AI) project like this one. (57…

Jeng, Ling Hwey – Information Processing and Management, 1991
Describes a study which investigated the general patterns and level of applicability of Anglo American Cataloging Rules (AACR2). It is suggested that designers and revisers of AACR2 should reduce the number of rules of very limited applicability levels and enhance the rule contents for application domains to expand the usefulness of AACR2.

Brooks, H. M. – Information Processing and Management, 1987
Explores what an intelligent information retrieval system involves and why expert system techniques might interest system designers. Expert systems research is reviewed with emphasis on components, architecture, and computer interaction, and it is concluded that information retrieval is not an ideal problem domain for expert system application at…
