| ### Dataset Summary | |
| 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*. | |
| For more details see [Recognising and Interpreting Named Temporal Expressions](https://aclanthology.org/R13-1015.pdf) | |

| ## Dataset Structure | |
| ### Data Instances | |
| ### Data Fields | |
| Each tweet contains an ID, a list of tokens, and a list of timex chunk flags. | |
| - `id`: a `string` feature. | |
| - `tokens`: a `list` of `strings` . | |
| - `ntimex_tags`: a `list` of class IDs (`int`s) for whether a token is out-of-timex or in a timex chunk. | |
