Gautam Bhattacharyya · SRELS Journal of Information Management · 1982
Furnishes a brief account of the fundamentals and procedure of POPSI (Postulate-based Permuted Subject Indexing) Language. Demonstrates how POPSI Specifics are derived by systematic manipulations of POPSI-Basic. Outlines the features of the vocabulary control device for POPSI called Classaurus- a faceted systematic scheme of hierarchical classification having all the necessary features of a conventional theasurus.
