Abstract

A Program-Package containing fifteen programs for use in the design, development, and operation of a system for document finding (SDF) is described. The computer-based SDF integrates within it a Freely-faceted Scheme for Classification of subjects. The system provides for: 1 Retrospective search for entries of documents relevant to a reader's query in a Catalogue on- Tape; 2 SDI service; 3 Reader's approach oy name of subject, author, collaborator, series, etc; 4 Reader Profile Catalogue in which the subject of interest to the reader may be in the form of Class Number, or Feature Heading only, or Class Number and Feature Heading; 5 Acceptance of reader's query about a subject in the form of Kernel Terms in random sequence; 6 Replacement of non-standard terms, if any, in the query, by standard terms in the classification schedules through a built-in thesaurus of a special kind; 7 Rearrangement of the Kernel Terms of a subject in the facet structure sequence using schedules in which the kernel ideas are arranged in a special way; 8 Synthesis of Class Number for Subject of document or of query using Colon Classification; 9 Translation of Class Number into Kernel Terms to form Feature Heading; 10 Direct reader-computer "dialogue"; 11 Browsing, in the output documentation list among its classified entries fitted with adequate Feature Headings; 12 Alphabetical Index to the Subjects etc of the output documentation list; 13 Different formats of Main Entry in the output; 14 Output on link printer, punched card, and magnetic tape; 15 Updating the Catalogue on-Tape, the Catalogue of Reader Profile-on-Tape, and the Classification Schedules-an-Tape ; and 16 Guidance by computer to help reader to use the system.

Abstract

The characters in the Class Number, according to Colon Classification consists of alphanumeric, and special characters, and varies from one record to another. The problems in using a digital computer for arranging the Class Number in the preferred sequence are considered. A program, using the two-way merge technique, in Autocoder language for an IBM 1401 Computer, has been developed and tested.

Abstract

A schedule look-up procedure for the translation of Colon Class Number into the standard terms of the schedules to form a Feature Heading using a computer, is described. The methods used for recognising a devised isolate number and an unsought link are mentioned. The procedure for preparing cyclically permuted Class Index Headings is described briefly.

Abstract

The linear relation between the number of discoveries and the number of re-discoveries in the field of antibiotics conforms to the Square-Cube Law as applied to growing organisms. The Square-Cube Law relation gives a rriore precise prediction of the number of rediscoveries of antibiotics given the number of reports of discoveries of antibiotics, than with the least square technique, reported earlier. There is isometry between the relative rate of growth of the cumulative total number of discoveries and the cumulative total of the number of re-discoveries.
