A COREFERENTIALLY ANNOTATED CORPUS AND ANAPHORA RESOLUTION FOR CZECH

The paper presents an overview of a finished project focused on annotation of grammatical, pronominal and extended nominal coreference and bridging relations in the Prague Dependency Treebank (PDT 2.0). We give an overview of existing similar projects and their interests and compare them with our project. We describe the annotation scheme and the typology of coreferential and bridging relations and give the statistics of these types in the annotated corpus. Further we give the final results of the interannotator agreement with some explanations. We also briefly present the anaphora resolution experiments trained on the coreferentially annotated corpus and the future plans.
