we present an implelnented system for processing definite descriptions. The system is based on the re- sults of a corpus analysis previously reported, which showed how common discourse-new descriptions are in newspaper corpora, and identified several problems to be dealt with when developing compu- tational methods for interpreting bridging descrip- tions. The annotated corpus produced in this ear- licr work was used to extensively evaluate the pro- posed techniques for matchiug delinite descriptions with their antecedents, discourse segmentation, rec- ognizing discourse-new descriptions, and suggest- ing anchors for bridging descriptions. 1 Motivation In previous work (Poesio and Vieira, 1998) we re- ported the results of corpus annotation experiments in which the subjects were asked to c...
