Peer reviewedBookstein, Abraham – Journal of the American Society for Information Science, 1974
Defines a hash coding model for non-unique search keys and derives the expected number of accesses needed to retrieve all desired records from a computer storage device. (Author)

Peer reviewedSaracevic, Tefko – Journal of the American Society for Information Science, 1971
The main conclusions are: the human factor appears to be the main variable in all components of an information retrieval system; length of indexes affects performance considerably more than indexing languages; question analysis and search strategies affect performance to a great extent - as much, if not more than indexing.

Peer reviewedBrooks, Terrence A. – Journal of the American Society for Information Science, 1988
Proposes a solution to the problem of loading repetitive bibliographic information in a microcomputer-based relational database management system. The alternative design described is based on a representational redundancy design and normalization theory. (12 references) (Author/CLB)

Peer reviewedMacleod, Ian A. – Journal of the American Society for Information Science, 1991
Compares two models used for text storage and retrieval systems, the text model and the relational model. Characteristics of documents and document collections are discussed, trends in document processing are described, and future directions of document management systems are suggested. (20 references) (LRW)

Peer reviewedPetry, Frederick E.; Cobb, Maria A. – Journal of the American Society for Information Science, 1998
Presents a model for representing and storing binary topological and directional relationships between 2-dimensional objects that is used to provide a basis for fuzzy querying capabilities. A data structure called an abstract spatial graph (ASG) is defined for the binary relationships that maintains all necessary information regarding topology and…

Peer reviewedLindquist, Mats G. – Journal of the American Society for Information Science, 1978
An analysis of computer-based search services (ISSs) from a system's viewpoint, using a continuous simulation model to reveal growth and stagnation of a typical system is presented, as well as an analysis of decision making for an ISS. (Author/MBR)

Peer reviewedParker, Ralph H. – Journal of the American Society for Information Science, 1982
Examines the distribution of use of items in a large information store and suggests that a simple exponential model describes the process of obsolescence more precisely. Three tables, four figures, and a 17-item reference list are included. (Author/JL)

Peer reviewedAdams, Carl; And Others – Journal of the American Society for Information Science, 1991
Discusses three configurations that were developed for the Integrated Information Center (IIC) at the University of Minnesota. These configurations--basic, intermediate, and advanced--represent increasing sophistication of support capabilities, increasing costs, and possible stages of implementation, depending on the requirements of the academic…
