TheInfoList




A discourse relation (or rhetorical relation) is a description of how two segments of discourse are logically and/or structurally connected to one another. It is widely accepted that Coherence (linguistics), coherence in text is established through text relations that constitute paratactic (coordinate) or hypotactic (subordinate) relations that hold across two or more text spans. Selected theories and annotation frameworks of discourse relations include: * Rhetorical Structure Theory (RST) that uses rhetorical relations as a systematic way for an analyst to analyse the text. An analysis is usually built by reading the text and constructing a tree using the relations. * Segmented discourse representation theory" (SDRT)


SDRT

Asher and Lascarides categorize the discourse relations formalized in SDRT into five classes.


Content-level relations


Text structuring relations


Divergent relations


Metatalk relations
