We investigate methods to improve the re- call in coreference resolution by also trying to resolve those definite descriptions where no earlier mention of the referent shares the same lexical head (coreferent bridging). The problem, which is notably harder than iden- tifying coreference relations among men- tions which have the same lexical head, has been tackled with several rather different ap- proaches, and we attempt to provide a mean- ingful classification along with a quantita- tive comparison. Based on the different mer- its of the methods, we discuss possibilities to improve them and show how they can be ef- fectively combined.
