text: Information as well as the use of expert Information with unknown and dlffleult to assess Indicators of accuracy and. reliability. Directions In solving this problem are the following. In case of accumulation and processing of large arrays of retrospective and current· technlco-economlc Information It Is further development of data banks of various levels and aspects which ensure col lectlve access of various ·subscribes engaged In forecasting In different fields of SandT progress. o In the field of patent Information the All-Union state ~ standard and methodloglcal recommendations for patent research "" was 1·ssued In 1984 which Includes methods of evaluation of 22-3 331 technology level and forecasting trends on the basis of statistical processing of patent and firms' Information. At present an automated system of patent lfnormatlon has been created In the USSR which by 1985 wll I be able to ensure for the users the posslbll lty of statistical processing and tracking of trends In a given field of S and T development In the world Invention beginning with 1920. Major problems related to expert sources of Information mainly consist In the formation of expert group for forecasting with high average competence of. Its participants, In the preparation of Initial Information while carrying out Inquests to ensure maximum rei lability of evaluation results, In finding and real lzatlon of Incentives conditioning high Interest of experts In formulating qual ltatlve evaluations, In the organization of such procedure of work with the experts which would not take much time, be simple and not tiresome for an expert. Col lectlve or Individual lnquestlng with the use of dialogue mode of operation of computers having the necessary volume of alI accessible Infor­ mation for a given forecasting problem seems to be a very promis­ Ing direction of this work. Efficiency of forecasts The problem of realization of forecasting results Is closely 
analysis: The text discusses the accumulation and processing of large arrays of technoeconomic information, patent research, and forecasting trends in various fields of scientific and technological progress. It highlights the importance of expert sources of information, dialogue mode of operation of computers, and the need for efficient forecasting results. These topics suggest that the text is related to the development and application of scientific and technological knowledge.
