INFORMATION RETRIEVAL

Abstract

This paper is divided into two distinct parts. The first is a summary of the general theory of information retrieval. A comprehensive mathematical model is described in terms of the theory of Boolean lattices, which serves to unify and make precise the basic problem of information retrieval. All possible basic methods of coding information for storage and retrieval are briefly described and contrasted. Another mathematical model for information retrieval based on linear graphs and stochastic processes is briefly described as an alternative to the lattice model. The appendices contain a survey of lattice theory, and an example of superimposed coding. The second part of this paper is a detailed example of the application of information retrieval techniques utilizing the facilities of the USNPGS Computer Center to handle a problem involving the technical reports section of the school library.
