A low-cost automatic classification method is reported that uses computer time in proportion to NlogN, where N is the number of information items and the base is a parameter, some barriers besides cost are treated briefly in the opening section, including types of intellectual resistance to the idea of doing classification by content-word…

The feasibility of completely automating the Minnesota Multiphasic Personality Inventory (MMPI) was tested, and item response latencies were compared with other MMPI item characteristics. A total of 26 scales were successfully scored automatically for 165 subjects. The program also typed a Mayo Clinic interpretive report on a computer terminal,…

This report describes work concerned with the statistical evaluation of the output of MEDICO automatic indexing procedure. The statistical tests were designed to examine the validity of the assumptions which formed the bases of the indexing algorithms with primary emphasis on the algorithm development for the computation of weights and links. Some…

Discusses the use of computer information systems to aid in library management functions such as planning, control, and decision making. Outlined are applications of macroanalysis (comparative library data, performance measures, use statistics) and microanalysis (circulation, acquisition, catalog support, and online catalog systems).

The objectives of this research were to investigage (1) the feasibility of an index simulator, and (2) the use of a sequential analysis model for the automatic classification of documents. Index simulation was studied in general for various types of indexes, and in depth for the simulation of an inverted coordinate index to a document collection…

This volume tells stories about the tools we use, but these narratives are told in numbers rather than in words. Organized by various aspects of society, each chapter uses tables and statistics to examine everything from budgets, costs, sales, trade, employment, patents, prices, usage, access and consumption. In each chapter, each major topic is…
