Generation Of Thesaurus In Different Languages A Computer Based System

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'ln language and linguistic studies. The significant contributions o f the theories o f 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-proposltlons, formulated according to the subject analysis techniques, enriched with certain codes for relating the terms in the subject-proposltlons has been developed. The system generates hierarchlc, 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.
