METHOD OF INTERACTIVE SEARCH IN DISTRIBUTED COMPUTER NETWORKS AND INFORMATION RETRIEVAL SYSTEM TO THIS EFFECT

摘要

FIELD: automation.;SUBSTANCE: invention relates to automation of training and scientific researches and can be used in interactive systems of automation of research works. The method of interactive search in distributed computer networks includes integration of processes of formation of interactive search inquiries and digital conversions of the results of measurements of corresponding signals in every channel of formation of search inquiries. Here, input signals of search inquiries are separated into two groups, the first group incorporating time-independent interactive search inquiries and the second one including those time-dependent. Now, the channels of measurement are selected for the aforesaid both search inquiries signals, a combinatory polling is effected, for example, exhaustive search of combinations, an appropriate number of channels of measurement and measurement of parameters of signals in each channel of search inquiries formation. Here, measurement of signals from the first group is effected on the basis of values of scatter of their lower and upper limits of variations allowing for tolerable, for example, absolute error of measurement in corresponding time intervalT_j=t_i1+1-t_i1 of measurement for all t∈[t_i, t_i1+1], i₁=1, 2, etc. Now, the duration of the temporary intervalT_i1 of formation of interactive search inquiries is corrected on the basis of values of the signal of mismatch of the affinity of the document content to a query or information need in previous interval T_i1-1 of formation of search inquiries. Also, the system of implementation of the proposed method is claimed.;EFFECT: higher efficiency of interactive search processes, higher accuracy, reliability and objectivity of search results.;3 cl, 16 dwg
