Analysis and Reference Resolution of Bridge Anaphora across Different Text Genres

We discuss bridge relations in Dutch between two textual referents across six di↵erent text genres. After briefly presenting the annotation guidelines and inter-annotation agreement results, we conduct an in-depth manual analysis of the di↵erent types of bridge relations found in our data sets. This analysis reveals that for all genres bridging references stand mostly in a class relationship, which is exactly the kind of information represented in a WordNet hierarchy. This inspired us to investigate to what extent a standard coreference resolution system for Dutch is capable of resolving bridge relations across di↵erent text genres and study the e↵ect of adding semantic features encoding WordNet information. Our results reveal modest improvements when using Dutch WordNet LCS information for all but one genre.
