A NOTE ON A SET OF FUNCTIONS FOR INFORMATION RETRIEVAL

An information retrieval system for experimental use is considered and a notation is introduced to help in its description. The system is experimental in that it is designed to facilitate the examination of the effect of different keyword classifications on retrieval performance. The notation derives from the basic operations encountered in information retrieval and examples are given of its use in a system which has already been implemented on a computer. These operations and their relevance to retrieval system is described in detail. Consideration is given to store allocation in the implementation of such a system and a simple method of automatic allocation is presented. © 1969.
