DOCUMENT RETRIEVAL SYSTEM OPERATIONS INCLUDING THE USE OF MICROFICHE AND THE FORMULATION OF A COMPUTER AIDED INDEXING CONCEPT
Abstract
Additional part-time indexers were trained according to a previously established training program. Many documents are now being received in microfiche form. Several makes of microfiche readers were evaluated, particularly with regard to their use by indexers. One make offered the most advantages, and a number of these readers were purchased. A method of producing typed hard copy abstracts from microfiche was found. The number of search requests increased with requests both from outside organizations and from the AFML accounting for the increase. The thesaurus was updated and a separate section containing only metallic materials terminology made the thesaurus easier to use. A computed aided indexing concept was formulated which is based on analysis of technical text. Text words are matched against files of nontechnical words, technical words and bound terms. Words not recognized are presented for human intellectual decisions which are subsequently incorporated into the system. The concept included a self-contained document analysis, storage and retrieval system with which requestors could interact by means of remote access terminals. Remote communication capability with the computer was accomplished, some programs were prepared and file structures based on word length and alphabetization of the first two characters were designed.
