Previous: Our Focus Model for
As mentioned in the introduction, one goal of this work is to assess
the adequacy of a recency-based focus model for this task and genre.
To be well founded, such evaluations must be made
with respect to a particular set of relations.
For example, the modify relation
supports a recency-based approach.
Consider the following example, reproduced from
The Need for Explicit Identification of Relations
|(1) Monday looks good.
|| Assume: Monday 19 August
|(2) How about 2?
|| (co-reference relation) 2pm,

without this relation might require
(3)'s antecedent to be provided by
