FIRST LETTER FREQUENCY OF RELATED TERM REFERENCES IN FOUR TECHNICAL THESAURI

Abstract

The method was to compare the first letter frequencies in the thesauri with each other, with the first letter frequencies of their descriptors, and with the pattern noted by other investigators. The thesauri selected were The Engineers' Joint Council Thesaurus of Engineering Terms (EJC), the Defense Documentation Center's Thesaurus of Astia Descriptors (ASTIA), the Medical Subject Headings of the National Library of Medicine (MESH); and the Medical and Health Related Sciences Thesaurus of the Public Health Service (MHRST). The related terms did not follow the first letter frequency pattern of their own descriptors or of that reported in the literature. The principal difference was in redundancy of letters within their own letter section. The thesauri were fairly consistent in this difference. In addition to word redundancy, there seemed to be an additional factor resulting in the redundancy.
