title: Augmented dataset of rumours and non-rumours for rumour detection

description: This data set contains a collection of Twitter rumours and non-rumours during six real-world events: 1) 2013 Boston marathon bombings, 2) 2014 Ottawa shooting, 3) 2014 Sydney siege, 4) 2015 Charlie Hebdo Attack, 5) 2014 Ferguson unrest, and 6) 2015 Germanwings plane crash

The data set is an augmented data set of the PHEME dataset of rumours and non-rumours based on two data sets: the PHEME data [2] (downloaded via https://figshare.com/articles/PHEME_dataset_for_Rumour_Detection_and_Veracity_Classification/6392078), and the CrisisLexT26 data [3] (downloaded via https://github.com/sajao/CrisisLex/tree/master/data/CrisisLexT26/2013_Boston_bombings).

 

<strong>PHEME-Aug v2.0 (aug-rnr-data_filtered.tar.bz2 and aur-rnr-data_full.tar.bz2) </strong>contains augmented data for all six events.

<strong>aug-rnr-data_full.tar.bz2</strong> contains source tweets and replies without temporal filtering. Please refer to [1] for details about temporal filtering. The statistics are as follows:

* 2013 Boston marathon bombings: 392 rumours and 784 non-rumours 

* 2014 Ottawa shooting: 1,047 rumours and 2,072 non-rumours 

* 2014 Sydney siege: 1,764 rumours and 3,530 non-rumours 

* 2015 Charlie Hebdo Attack: 1,225 rumours and 2,450 non-rumours 

* 2014 Ferguson unrest: 737 rumours and 1,476 non-rumours 

* 2015 Germanwings plane crash: 502 rumours and 604 non-rumours 

 

<strong>aug-rnr-data_filtered.tar.bz2 </strong>contains source tweets, replies, and retweets after temporal filtering and deduplication.  Please refer to [1] for details. The statistics are as follows:

* 2013 Boston marathon bombings: 323 rumours and 645 non-rumours 

* 2014 Ottawa shooting: 713 rumours and 1,420 non-rumours 

* 2014 Sydney siege: 1,134 rumours and 2,262 non-rumours 

* 2015 Charlie Hebdo Attack: 812 rumours and 1,673 non-rumours 

* 2014 Ferguson unrest: 471 rumours and 949 non-rumours 

* 2015 Germanwings plane crash: 375 rumours and 402 non-rumours 

 

The data structure follows the format of the PHEME data [2]. Each event has a directory, with two subfolders, rumours and non-rumours. These two folders have folders named with a tweet ID. The tweet itself can be found on the 'source-tweet' directory of the tweet in question, and the directory 'reactions' has the set of tweets responding to that source tweet. Also each folder contains ‘aug_complete.csv’ and ‘reference.csv'.

'aug_complete.csv' file contains the metadata (tweet ID, tweet text, timestamp, and rumour label) of augmented tweets before deduplication and filtering tweets without context (i.e., replies).

'reference.csv' file contains manually annotated reference tweets [2, 3].
