This paper introduces ERIC searchers to the use of clearinghouse codes as search keys and includes a brief history of ERIC Clearinghouses, information on how codes are assigned, the use of clearinghouse codes in the WISE Search Program at the University of Wisconsin-Madison, and some examples of potential uses of codes in searching. Examples in…

Automatic processing of the bibliography on vapor-liquid equilibrium data is done by means of a specially developed mnemonic coding system. (Author/JB)

The boundary between two neighboring rings is called the fusion lines, which is enclosed by external segments called arcs. In the code, the separation of fusion line(s) from arcs takes place in such a way that proper matching is achieved. By this procedure, the structure of a compound is recreated. (Author)

Nearly all organizations are faced with problems of classifying and coding financial data, management and technical information, components, stores, etc. and need to apply some logical and meaningful system of identification. This report examines the objectives and applications of classification and coding systems and reviews eight systems…

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.…

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…

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…

Two systems, WLN and Ringcode, for retrieving structural information were analyzed qualitatively and evaluated for a series of chemical compounds. The studies ranged from specific to generic questions and also involved retrieval by fragments. Neither system was completely satisfactory for all types of searches. (6 references) (Author)

An access method for bibliographic records that combines features of the search key approach and the inverted file approach. Permits extension of search key technique to large files. (Author/LS)

THIS PROJECT SOUGHT TO DEVELOP AN OPERATIONAL "TOTAL" DATA SYSTEM FOR AN INSTITUTE OF HIGHER EDUCATION. THE REPORT SYNTHESIZES MANY PREVIOUS EXPERIENCES IN DATA PROCESSING, IN ORDER TO PRESCRIBE A MANAGEMENT INFORMATION SYSTEM SUITED TO COLLEGES AND UNIVERSITIES. IT WAS FELT THAT A BROAD BASE, GENERAL PURPOSE INFORMATION SYSTEM WOULD…

The author proposes a system using the HUC to identify all information and knowledge which can be reduced to a written, pictorial, oral, or machine readable record. The code designations, which may consist of letters, numerals, and other symbols and which average 12 to 18 characters in length, provide information in 12 fields: type of material,…

This document is a review of Canada's attempt to develop a standardized, multipurpose occupational classification system suited to national requirements. The main objective of Volume 1 the CCDO is to provide an instrument for use in manpower research and analysis, for statistical survey purposes, census taking, and for operational activities such…

THE FEASIBILITY OF EMPLOYING ELECTRONIC COMPUTERS AS RESEARCH AND OPERATIONAL TOOLS IN THE AREA OF SCHOOL LAW WAS TESTED. TEXT MATERIAL WAS SELECTED, MARKED FOR TYPING BY AN ATTORNEY, AND TRANSFERRED TO MAGNETIC TAPE THROUGH THE INTERMEDIATE STEPS OF PUNCHED PAPER TAPE AND IBM PUNCH CARDS. A CONCORDANCE PROGRAM BROKE DOWN THE TEXT INTO ALPHABETIC…

Rooted binary trees with weighted nodes are structures encountered in many areas, such as coding theory, searching and sorting, information storage and retrieval. The path length is a meaningful quantity which gives indications about the expected time of a search or the length of a code, for example. In this paper, two sharp bounds for the total…
