Discourse Processing, by Manfred Stede, Potsdam University

Synthesis Lectures on Human Language Technologies #15
(Morgan & Claypool Publishers), 2012, 165 pages


Discourse Processing here is framed as marking up a text with structural
descriptions on several levels, which can serve to support many
language-processing or text-mining tasks. We first explore some ways of
assigning structure on the document level: the logical document
structure as determined by the layout of the text, its genre-specific
content structure, and its breakdown into topical segments. Then the
focus moves to phenomena of local coherence. We introduce the problem of
coreference and look at methods for building chains of coreferring
entities in the text.  Next, the notion of coherence relation is
introduced as the second important factor of local coherence. We study
the role of connectives and other means of signaling such relations in
text, and then return to the level of larger textual units, where tree
or graph structures can be ascribed by recursively assigning coherence
relations. Taken together, these descriptions can inform text
summarization, information extraction, discourse-aware sentiment
analysis, question answering, and the like.
