This is a dataset annotated for named temporal expression chunks.
The
commonest temporal expressions typically
contain date and time words, like April or
hours. Research into recognising and interpreting these typical expressions is mature in many languages. However, there is
a class of expressions that are less typical,
very varied, and difficult to automatically
interpret. These indicate dates and times,
but are harder to detect because they often do not contain time words and are not
used frequently enough to appear in conventional temporally-annotated corpora –
for example Michaelmas or Vasant Panchami.
