In this course we discussed the use of
annotated corpora to study anaphora and anaphora resolution. After
briefly reviewing the semantics and
pragmatics of anaphoric expressions, we discussed first of
all the problems involved in creating a corpus annotated with
anaphoric information. We then discussed work concerned with using
corpora to explore theories of salience (such as
Grosz and Sidner's theory and Centering theory) and the empirical
concerning their claims. We then discussed the use of corpora to
develop computational models of anaphora resolution, with particular
concern for bridging references.
