To judge the performance of temporal taggers and new methods, evaluations need to be performed on diverse text types, e.g., on news articles and narrative-style Wikipedia documents.
to many natural language processing tasks, there has also been some effort towards multilinguality in the context of temporal tagging, e.g., research competitions were organized not only for English but covered further languages such as Spanish and Italian (Verhagen et al., 2010;Caselli et al., 2014).
