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.…

Presents the "Evidence-of-Existence" information system in which the structure is developed, with application of cybernetic concepts, as an isomorphic model in analogy to the system structure of communication technology. Three criteria of structuring are postulated: (1) source-channel-sink, with input-output characteristics, (2) filter-type…

The chemical coding scheme of the Medical Coding Scheme (MCS), developed for use in the Comparative Systems Laboratory (CSL), is outlined and evaluated in this report. The chemical coding scheme provides a classification scheme and encoding method for drugs and chemical terms. Using the scheme complicated chemical structures may be expressed…

This handbook is designed to assist its users in gathering information about elements of educational technology by defining standardized terms and providing a structure showing the interrelationships between those terms. It is intended to serve as a reference tool for researchers, statisticians, and others who gather and interpret data about…

This book deals with properties of vocabularies for indexing and searching document collections; the construction, organization, display, and maintenance of these vocabularies; and the vocabulary as a factor affecting the performance of retrieval systems. Most of the text is concerned with vocabularies for post-coordinate retrieval systems, with…

The purpose of this project was to provide guidance to ERIC on how to facilitate product information retrieval.
