## Dataset Details

The Longitudinal Rumour Stance (LRS) is a longitudinal version of the RumourEval-2017 dataset. It consists of Twitter conversations around
newsworthy events. The source tweet of the conversation conveys a *rumourous* claim, discussed by tweets in the stream. In 325 conversations, a total of 5,568
posts are labelled based on their stance towards the rumourous claim in the corresponding source tweet as either Supporting, Denying, Questioning or Commenting.
We convert conversation structure and labels into a Longitudinal Stance Switch Detection task.

Specifically, conversations are converted from tree-structured into linear timelines to obtain chronologically ordered
lists. Then the original stance labels from the RumourEval-2017 dataset are converted into a binary label of *Switch* and *No Switch* categories based on the
numbers of supporting tweets versus denying and questioning ones at each point in time.

More precisely this longitudinal task captures switches in overall user stance:
- Switch: switch between the total number of oppositions (query/deny) and supports or vv
- No Switch: absence of a switch or balance between the numbers of supporting and opposing posts


## Dataset Structure

```id```: a type ```float64``` unique id for each tweet

```timeline_id```: a ```string``` type unique id for each timeline. A timeline is a linear chronologically ordered conversation converted from the tree-structured conversation.

```datetime```: date and time of the tweet

```text```: a ```string``` type text of the tweet

```label_binary```: a type ```float64``` binary label of either *Switch* (1) or *No Switch* (0)

```label```: a type ```float64``` binary label of either *No Switch* (0), a switch in stance from supporting to opposing the claim starts (-1), a switch in stance from opposing to supporting the claim starts (1), a switch in stance from supporting to opposing the claim continues (-2), a switch in stance from opposing to supporting the claim continues (2).


### Data Splits

Each split has unique timelines.
