Abstract
The paper presents expert systems as a new generation of information storage and retrieval systems which may consider ably improve the processes of scientific and technical informa tion exchange and dissemination. Essential features of the expert systems with databases containing scientific or technical information have been specified. For databases in which a semantic network is used as a knowledge representation scheme, an idea of database organization has been described with some attention paid to the problem of extracting factual information from the texts of scientific and technical publications. The process of information retrieval from the database of a scien tific or technical information expert system has also been briefly described.
