Abstract
<jats:p>This article examines contemporary approaches to the classification of intra-textual connections and discourse relations. Key theories from the 20th and 21st centuries are analyzed, including Segmented Discourse Representation Theory, annotated corpora, and O.Y. Inkova’s connector theory. Special attention is given to classification criteria such as semantic level, truth status, and semantic similarity of text fragments. The significance of multi-level and faceted analysis for identifying both explicit and implicit discourse relations is emphasized. The role of corpus studies and annotation in integrating theoretical and empirical data is discussed. It is noted that contemporary models allow for consideration of the cognitive, semantic, and pragmatic aspects of text. These approaches provide analytical universality for texts of different genres and languages. The article highlights the prospects of integrating linguistic theories with artificial intelligence methods in the study of discourse structure. Keywords: discourse relations, segmented representation, annotated corpora, connector theory, cognitive linguistics, semantic analysis, rhetorical structure</jats:p>
