Information and Its Retrieval
Abstract
Information is defined abstractly as a set of highly structured elements. This structure induces a two-way classification of the elements and also other relations among them. The definition includes rules for expanding this information by incorporating new elements and for discarding elements that have become obsolete or are no longer needed. The definition of information is geared to its purpose, viz. to provide easy retrieval of known facts that are of interest to a specialist in the field. A pilot example of such a retrieval system is included, and principles for the physical realization of the system are presented. It is stated that a clear distinction must be made between a collection of documents and the information they contain. Likewise, the difference between recovering relevant documents and retrieving desired information is emphasized.
