SEARCH ALGORITHM IN COMPUTER SYSTEMS AND DATABASES

摘要

FIELD: information technologies.;SUBSTANCE: invention relates to search tools in computer systems and databases. Method includes text information indexing, entering a query and searching by index. To index the database of texts stored in the database, using the search system, calculating the rhythmic characteristics of the texts, namely vectors that encode the rhythmic properties of text individual lines and the entire text as a whole. Construction of vectors by a search system occurs in two stages. At the first stage, line is segmented into syllables, after which the line automatically puts the stresses and at the output of the first stage in the line of text the syllable boundaries are arranged and for each of them it is indicated, unstressed or search system can not uniquely determine its stress. At the second stage, the search system computes a vector for each line of text, and then calculates an aggregated vector for all text, which determines the rhythmic structure of this text. Aggregated vector is stored in a vector storage that supports the nearest neighbors search function. Performing a query input in text or pseudo-text form to find text data, suitable audio data.;EFFECT: technical result consists in providing the possibility of selecting musical and text information to each other on the basis of their rhythmic properties.;5 cl, 5 dwg
