- Abstract
- The Deep Structure Indexing System is based on: (1) a set of postulated elementary categories of the elements fit to form componentes 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. Names of subjects formulated on the basis mentioned above are input to a set of computer programs to generate several different types of subject index entires. This paper describes briefly the Deep Structure Index System
