Schneider, John H. – Drexel Library Quarterly, 1974
Discusses the role of certain types of classifications in a modern automated environment. (Author/PF)
Descriptors: Automatic Indexing, Automation, Classification, Computers
And Others; Prywes, Noah S. – Information Storage and Retrieval, 1974
Reports on a series of programs that have been developed to process data bases, consisting of textual items, and to index and arrange (classify) the data items in accordance with an automatically generated classification system. (Author)

DeBardeleben, Marian Z.; Lunsford, Carol G. – Special Libraries, 1982
Recounts the development of a slide storage and retrieval system at the Philip Morris Research Center in Richmond, Virginia and describes the methods used to classify and access slides in the collection. A reference list and three appendices accompany the text. (JL)

Landry, Bertrand C.; Rusk, James E. – J Amer Soc Info Sci, 1970
Deals with the relationship between a theory of indexing and a theory of information storage and retrieval. Attention is directed to the view that indexing is an order increasing operation, and some thermodynamic notions are invoked to aid in this description. (MF)

Vance, David – 1974
This paper describes the process of automatic extraction of implicit--global--data from explicit information by file inversion and threading. Each datum is the symbolic representation of a proposition, and as such has a number of movable parts corresponding to the ideal elements of the proposition represented; e.g., subject, predicate. A third…

Meincke, Peter P. M.; Atherton, Pauline – Journal of the American Society for Information Science, 1976
Proposes a new conceptual basis for visualizing the organization of information, or knowledge, which differentiates between the concept "vectors" for a field of knowledge represented in a multidimensional space, and the state "vectors" for a person based on his understanding of these concepts, and the representational…

Howard Research Co., Arlington, VA. – 1966
This report presents the identification and definitions of subject oriented engineering and scientific disciplines and fields which are included in the EDIS Subject Categories. The discussion is extended to include the mix of subjects with other orientations, such as Item, Mission-Project, Expertise and Data Bank Categories. Sample queries are…

Soergel, Dagobert – Drexel Library Quarterly, 1982
This discussion of the general principles of structure and construction of numeric databases introduces the concept of data points, their relationship to each other, and their storage in a nonredundant way. The collection of numeric data and their integration into the database structure are explained. Eight references are cited. (EJS)

Williams, John H., Jr. – 1966
A series of experiments was performed to investigate the effectiveness and utility of automatically classifying documents through the use of multiple discriminant functions. Classification is accomplished by computing the distance from the mean vector of each category to the vector of observed frequencies of a document and assigning the document…

Hody, George L. – 1969
The U.S. Army Aeromedical Research Laboratory (USAARL) is often required to make specialized measurements and perform applied research in aircraft-related areas of environmental medicine. Rapid access to the periodical literature is essential for the completion of many of these projects. A growing file of reprints from the periodical literature is…

Alt, Franz L.; Herschman, Arthur
Against a background of widespread interest in national information systems, the American Institute of Physics is developing such a system for physics. This program pivots on the design of a new classification system for physics which is to be used, in conjunction with free-language index terms, for the intellectual organization of the physics…

Litofsky, Barry – 1969
Large-scale, on-line information storage and retrieval systems pose numerous problems above those encountered by smaller systems. A step toward the solution of these problems is presented along with several demonstrations of feasibility and advantages. The methodology on which this solution is based is that of a posteriori automatic classification…

Sparck Jones, K.; Van Rijsbergen, C. J. – Journal of Documentation, 1973
Substantial alterations to a system often have little or no effect on particular collections. This may be due to poor separation of relevant and non-relevant documents. The paper presents a procedure for characterizing this separation, which can show whether proposed modifications of the base system are likely to be useful. (8 references)…
