First sentence: After a break of three and a half years - the last issue being F. Rigg's "Indexing Glossary..." FID/CR is continuing its Report Series with a research paper in which the findings of Francis Devadason' s voluminous Ph.D thesis (649 p !) entitled "Computer based systems for generating different types of subject indexes and alphabetical classaurus based on 'Deep Structure of Subject Indexing Languages" are summarised.
Description: A Subject Indexing Language is an artificial  language used for formulating names of subjects. The Deep Structure Indexing System (DSIS) is based on 1) a set of postulated Elementary Categories of the elements fit to form components of names of subjects; 2) a set of syntax rules with reference to the categories; 3) a vocabulary control tool such as Classaurus; 4) a set of indicator digits to denote the categories and their subdivisions; and 5) a set of codes to denote a few of the decisions of the indexer, in order to generate by computer manipulation different types of subject index entries. The report also discusses the salient features of this system such as the production of POPSI subject index entries resulting in an "organizing classification effect" in the alphanumeric arrangement of subject headings. The system consists of programs written in COBOL & PL/1 tested at an IBM 370-155 II mainframe.
