Table 1

Annotation task (ST for sequence tagging, Cl for classification) and the number of instances per dataset and split. $μ_{| D |}$ denotes the average instance length in characters and μ_t the average annotation time. $σ_{| D |}$ and σ_t denotes the standard deviation, respectively. Across all datasets, annotation time is reported for annotating the whole instance (i.e., not for individual entities).
