The development of the theory of library classification and of subject indexing, for the organisation, storage and retrieval of subjects embodied in documents has a striking parallelism to the search for 'universal forms' and deep structure' in language and linguistic studies. The significant contributions of the theories of classification and subject indexing are the subject analysis techniques of Ranganathan and Bhattacharyya's POPSI. A computer based system, for generating an information retrieval thesaurus, from modulated subject-propositions, formulated according to the subject analysis techniques, enriched with certain codes for relating the terms in the subject-propositions has been developed. The system generates hierarchic, associative, coordinate and synonymous relationships between terms and presents them as an alphabetical thesaurus. Also, once a thesaurus is generated in one language it is possible to produce the same thesaurus in different languages by just forming a table of equivalent terms in the required language.
