Discourse relation
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 in text is established through text relations that constitute paratactic (coordinate) or hypotactic (subordinate) relations that hold across two or more text spans.[1]
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
In its original motivation, SDRT attempts to complement Discourse Representation Theory (DRT) with RST-style discourse relations. Asher and Lascarides (2003) categorize SDRT discourse relations into several classes:
- Content-level relations - Text structuring relations - Divergent relations - Metatalk relations
Metatalk relations include:
