Abstract

A method is presented for batch creation and maintenance of BRS thesaurus files . The thesaurus elaborated contains 7.500 terms corresponding to world geography and is used to control input and retrieval from severa! bibliographic and audiovisual databases. The load file structure, as well as the delimitations of terminological rclationships, have been performed using a microcomputer database management system. Semantic scope of every term has been represented by alphanumeric classificatory codcs, equivalencc relationship being represented by equality of notation and jerarquic relationships by inclusion of generic codes in the more specific ones. Thc procedure is also applicable to associative relationships. Processing is based on the connection between two main term files, one containing all terrns in alphabetic arrangement and the other sorting preferred term by their endes. Two additional files contain non preferred and associatcd terms. As a result, not only the alphabetic and hierarchical displays. out a combination of hoth are obtaincd, suitable for a later loading of the file in BRS thesaurus module. Source programs are provided.
