Discourse-level Analysis Task

A Discourse-level Analysis Task is a Linguistic Analysis Task of a Discourse that looks at Text Meaning beyond the individual Sentences.

• AKA: Extrasentential Semantic Analysis, Discourse Analysis, Discourse Analysis Task, Discourse-level Analysis.
• Context:
  • Input: a Linguistic Artifact.
  • output: Discourse Structure.
  • The entire Text (Discourse) gives additional meaning to its Constituent parts (e.g. Words and Sentences).
  • It can be solved by a Discourse-level Analysis Algorithm.
  • It can require the identification of Discourse Structure.
  • It can be supported by a Discourse Analysis Theory.
  • It can range from being a Single-Document Discourse Analysis Task to being a Corpus-based Discourse Analysis Task.
  • It can be:
    • a Linguistic Expression Entailment Task.
    • a Coreference Resolution Task.
    • a Topic Modeling Task.
  • …
• Example(s):
  • In the sentence "David was too far away to see." the Sentence Subject is not specified. The subject could be anyone, or it could be a specific person. The decision requires insight into the other Sentences in the Text. E.g. “X scanned the horizon in vain. Y was too distant to see."
  • TET("My cat is black”, “I have a black cat”) ⇒ True.
  • Coreference Resolution Task.
  • Topic Modeling Task.
  • …
• Counter-Example(s):
  • Sentence-level Analysis Task, such as a Syntactic Parsing Task.
  • Word-level Analysis Task,
• See: Centering Theory, Semantic Parsing, Mention Reference Resolution Task.
