This classification scheme attempts to demonstrate a method of controlling and organizing an indexing language for the physical forms of non-book media. The classification is based on the technique of facet analysis. It comprises a classification of the concepts of the subject with an alphabetical listing of the verbal descriptions of the subject.…

A survey of automatic indexing systems and experiments has been conducted by the Research Information Center and Advisory Service on Information Processing, Information Technology Division, Institute for Applied Technology, National Bureau of Standards. Consideration is first given to indexes compiled by or with the aid of machines, including…

The report contains five papers dealing with some problems of a general classification scheme covering the whole field of knowledge which were presented at a conference held in London, June 1963. Topics covered included retrieval schemes, classification problems, inadequacies of existing classification schemes and the proposal of the…

The largest patent libraries annually acquire over 300,000 descriptions. The tasks and problems of patent libraries are characteristic for patent libraries in many countries. However, until recently, international cooperation mainly boiled down to mutual patent document exchanges. These libraries did not participate in various international…

This report, a supplement to Technical Report Number 82, is designed to aid the researcher concerned with concept learning. It contains: (1) a rationale and strategy for compiling a bibliography of articles concerned with concept learning; (2) a definition of the word concept; (3) a system for classifying articles by their content; (4) a…

The basic index for minutes presented in this manual was developed to aid clerks in indexing their minute books. A minute book is an extremely important record, but reference to an unindexed or poorly indexed minute book can be a time-consuming problem. The manual outlines the procedure to be followed in setting up an index and maintaining it on a…

This report summarizes the work carried out on the automatic construction of keyword classifications and their use in information retrieval. It discusses the possible characteristics of such classifications, and potential ways of using them; and describes the various approaches to classification that were considered in terms of an overall frame of…

A need exists for a more clear-cut description of how the taxonomy of educational objectives can be implemented in the school setting. In answer to that need, a way is shown to formulate specific behavioral objectives within the hierarchy of the major levels and sublevels of the taxonomies as set forth by Bloom (1956) and Krathwohl (1964). To…

The idea of pseudo-classification based on external relevance was introduced and compared with the usual classifications using associative techniques. A general model for an information retrieval system using term classification was described. A set of operators for adjusting pseudo-classifications and preventing their deterioration was derived…

The contents of this report are designed to aid the researcher concerned with concept learning. This publication contains: (1) rationale and strategy for compiling the bibliography, (2) a definition of the word concept, (3) a system for classifying articles by their content, (4) a bibliography of articles dealing with concept learning from 51…

The problem which this study addresses is the effects of cognitive style and variations in the free sort procedures on the sorting outcome of sorting time and number and quality of manifest partitions. This experiment was designed to look at the effects of the cognitive styles of field dependence, category width and equivalence range,…

The field of education serves as the basis for this discussion on the use of categories in a thesaurus for information processing and documentation purposes. The author briefly shows how a number of writers concerned with the structure of the field of education, as well as makers of classification schemes, have commented on the value of setting up…

This report is intended to describe and analyze the present state and future needs of performance-based materials. It is limited to materials presently available for dissemination. The first section outlines the background of the project and describes the procedures for selecting, classifying, and describing the materials. The second section…

An account is given of the rationale, methodology, and preliminary results of an initial research effort to develop a scheme for use as a guide in generating and applying behavioral information. Objectives are to clarify relationships between military tasks and existing psychological knowledge, indicate training problems requiring further…

As a result of a concern over the adequacy of teacher rating instruments, a project was begun to develop a pool of items describing teacher behavior. Most of the items were derived from the literature; some were written by the project. The item pool presently consists of 1137 items subsumed under 19 categories. Examples of categories are: personal…
