For more than a decade, ÚFAL discourse-oriented research concentrated on the description of various linguistic aspects of local, “chain-like” coherence. Global coherence, on the other hand, assumes a hierarchical representation of smaller (clauses, sentences) and larger text units (e.g. paragraphs) and the existence of coherence relations between these units on all levels of the hierarchy. A single interconnected representation for the entire document is postulated, too.
In the lecture, one of the most influential models of global coherence will be introduced, the Rhetorical Structure Theory, along with its impact on corpus design, empirical annotation of coherence relations and natural language generation tasks.
