Theory of functional sentence perspective and its application for the purposes of automatic extracting

摘要

When preparing the more sophisticated methods of text analysis for information systems, an important role may belong to the applications of modified results gained on the basis of the theory of so called “functional sentence perspective”, working with the concepts of the “theme” of a sentence (that which is spoken about in the sentence) and of the “rheme” (that which is said about the theme in the sentence). From the standpoint of the need to establish the “informational content” of the text an analysis of this kind undoubtly is more important than a traditional examination of a subject-predicate relations etc. Along with a brief characterization of the results of this theory, the article analyzes the possibilities for the implementation of this theory in the theory of information systems, particularly with respect to the study of so called thematic progressions in the text and general structural formula of the text. Besides, particular attention is paid to the utilization of this theory in the domain of automatic extracting.
