TimeTank: A Corpus of Sentences Annotated with TimeInfo for Temporal Data

Annotating temporal information in texts is a challenging and time-consuming task. It requires an understanding of natural language, as well as knowledge about the various ways in which temporal data can be expressed and structured in a text. However, the ability to access temporal semantics through computer tools is crucial for many applications that involve interpreting and understanding texts.

A corpus available in this field is TimeBank (Pustejovsky et al., 2003), which was annotated using the TIMEX3 annotation scheme (Pustejovsky et al., 2003), a scheme that does not support complex temporal expressions.

We proposed a new annotation scheme for temporal information in scientific texts: TimeInfo (Yahiaoui & Atanassova, 2022) which allows for more precise and directly usable annotations. The corpus presented here, named TimeTank, consists of 1186 sentences containing a total of 1200 temporal expressions annotated according to the TimeInfo annotation scheme.
