Abstract
This paper describes the scheme of annotation of coreference in PDT. We represent the structure of annotation stages, which consist of grammatical coreference annotation (the antecedent can be calculated from the grammatical rules of the language), textual pronominal coreference and the extended scheme of textual coreference, which includes noun anaphoric relations and bridging anaphora.
We suggest and discuss coreference relations in the extended coreference scheme, examine some complications, which occur by annotation and present our first results.
