THE TDCK‐COMPACT SYSTEM

Abstract

TDCK uses a combination of uniterms and descriptors for its information retrieval system. In order to index two series of about twenty thousand documents each per year, a punched card with twenty thousand positions has been designed. In each series about eight thousand uniterms are used to describe the documents.
