摘要：Given the great amount of definite noun
phrases that introduce an entity into the
text for the first time, this paper presents a
set of linguistic features that can be used
to detect this type of definites in Spanish.
The efficiency of the different features
is tested by building a rule-based and
a learning-based chain-starting classifier.
Results suggest that the classifier, which
achieves high precision at the cost of recall,
can be incorporated as either a filter
or an additional feature within a coreference
resolution system to boost its performance.
