An Annotated Dataset of Coreference in English Literature
This dataset enables evaluation of cross-domain performance and analysis of long-distance coreference in literature, addressing a specific gap in NLP resources.
The authors introduced a new dataset for coreference resolution in English literature, containing 29,103 mentions across 100 works, with documents averaging 2,105.3 words, four times longer than previous benchmarks like OntoNotes.
We present in this work a new dataset of coreference annotations for works of literature in English, covering 29,103 mentions in 210,532 tokens from 100 works of fiction. This dataset differs from previous coreference datasets in containing documents whose average length (2,105.3 words) is four times longer than other benchmark datasets (463.7 for OntoNotes), and contains examples of difficult coreference problems common in literature. This dataset allows for an evaluation of cross-domain performance for the task of coreference resolution, and analysis into the characteristics of long-distance within-document coreference.
