Title (article) An Approach to Analysis of News Streams as Discrete Signals
Authors Lande D.V.
Kiev, Ukraine
Annotation A data processing model in which text information streams are considered as discrete signals is de-scribed. Frequency-semantic ranks of terms or documents are used as peak values of signals. Creation of the toolkit providing viewing of so-called «marginal» messages on subject-matter determined by user query is validated. The method actually answers the question — what are the least mentioned subjects within determined subject-matter for some time past. Refs: 9 titles.
Key words information streams, processing of signals, Internet, text corpus, ranking
