|Summary: Local Discourse and Reference|
Concentrating mostly on anaphoric reference to noun phrases, we
have described a simple algorithm for deciding what object in the
history list a phrase in the text refers to. The key ideas presented
include searching the history list in most-recent-first order, using
relationships between objects to determine indirect references. We
also looked briefly at the effects of the use of quantifiers like "each"
on the referent of an object within the scope of the quantifier.
