In Natural Language Processing, coreference resolution involves finding antecedents of referential expressions (e.g. pronouns or some definite nominals). The resolution of coreference depends on a combination of salience, syntactic, semantic and discourse constraints. The acquisition of such knowledge is difficult and could certainly benefit from a visualization tool, enabling the linguist researcher to find examples of coreference relations. Furthermore, an alternative knowledge-minimalist technique for resolving coreference can be developed by relying on text corpora annotated with coreference data. In this paper we present COREFDRAW, a tool that enables both the annotation of coreference data and its visualization from large text corpora. The resulting annotations enable enhanced coreference resolution methods.
