The purpose of this paper is to describe a method of finding the significant attributes of documents established during the course of research on the automatic classification of documents. The problem was first approached by examining the way in which an existing hierarchical classification system classifies things. The study of biological…

Student grouping on the elementary and secondary level is discussed. The three sections include: (1) historical perspective of grouping patterns, (2) grouping objectives and purposes, and (3) grouping criteria and practices. Emerging patterns of horizontal and vertical school organization represent a conscious attempt at flexibility. Also included…

The results of a project undertaken to develop a usable file of measures appropriate for use with children from birth through age 8 and to formulate a reliable system for cross-classifying instruments by construct and response methodology are presented. The completed file referenced 800 readily available measures from published and unpublished…

The reading list contains 180 references and serves as an introduction to classification research literature. While the list includes major viewpoints on basic work in the field of classification as well as related areas, it excludes critical literature. The major divisions of the reading list are: (1) Definition: What is Classification, (2)…

This outline of how to establish and maintain an Asian national union catalog contains basic instruction for the staff and for the participating libraries of one of West Asia's largest union catalogs. It has been prepared to: (1) define and clarify the purposes of the Iranian National Union Catalog; (2) explain the policies and procedures under…

The purpose of this study was to determine which of six methods of ordering variables in a discriminant analysis yields subsets of variables that have the greatest discriminatory power. One method is based on univariate mean-square (or F) ratios, a second method on stepwise ordering, two methods on linear discriminant function (LDF) variable…

This study examines strategic and semantic aspects of the answers given by preschool children to class inclusion problems. Results show that children understand the semantics of inclusion but are unable to coordinate their semantic knowledge with enumeration strategy. (Author/DEP)

Seven decades after Charles A. Cutter's death, his classification is still being used by a dozen American and Canadian libraries. These libraries are identified and their use of the Cutter classification is briefly discussed. (Author)

This study produced a taxonomy of planning data sources of use by comprehensive educational planners at the school district level. The taxonomy identifies and classifies these sources on the basis of the data they provide. (Author/IRT)

A numeric classification system has been devised for a meteorological data collection which is based upon World Meteorological Organization region numbers. An enriched KWIC index has been prepared for this collection, which contains material in a variety of physical forms. (Author)

Based on the example of economic research, the method outlined permits the drawing up of a typology of Social Science information sources. Resources are grouped in four categories: organizational framework, reference sources, periodicals, and information services. (Author/JAB)

A type of descriptor is suggested for application to the description and classification of information systems, and for the development of an information system typology. A list of 83 Function Descriptors developed in the exploratory description of 25 systems is provided. (Author/KP)

Individuals are classified in a cross-classification table where two behavioral observations on each individual determine the classification. The problem is to test certain structural models assumed to underlie the cross-classified observations. A minimum chi-square test procedure is proposed. (Author)
