SAPHIRE--an information retrieval system featuring concept matching, automatic indexing, probabilistic retrieval, and hierarchical relationships.

SAPHIRE (Semantic and Probabilistic Heuristic Information Retrieval Environment) is an experimental computer program designed to test new techniques in automated information retrieval in the biomedical domain. A main feature of the program is a concept-finding algorithm that processes free text to find canonical concepts. The algorithm is designed to handle a wide variety of synonyms and convert them to canonical form. This allows natural language to be used for query input and also serves as the basis for a new approach to automatic indexing based on a combination of probabilistic and linguistic methods.

[Development of an automated information retrieval system for the identification of antibiotics].

The basic points in the development of a specialized computer information search system providing ientification of new antibiotics at early stages of their investigation are described. The system of coding the physico-chemical properties of the agents and the spectra of their antimicrobial activity presenting the substance in the information bank is developed. The task of identification is to find in the reference bank according to some specially organized keys such antibiotics which are identical or close by their properties to the substance being identified. Mini-computer of M-6000 type is used as the technical base of the information search system. Preliminary organization of the bank specified by the coding system markedly reduces the requirements to the computer operative memory.
