A discourse relation (or rhetorical relation) is a description of how two segments of discourse are logically connected to one another.

One method of modeling discourse involves a set of concepts that constitute "segmented discourse representation theory" (SDRT).


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

Content-level relations[edit]

Text structuring relations[edit]

Divergent relations[edit]

Metatalk relations[edit]

  • Consequence*(α,β)[1]
  • Explanation*(α,β)[1]
  • Explanation*q(α,β)[1]
  • Result*(α,β)[1]
