Overview of the Classifying Concerning Tweets study
This study aimed to determine whether suicide-related Twitter posts could be classified as ‘strongly concerning’ based solely on the content of the post, as judged by human coders.
We wished to determine whether such content could be legitimately considered as an indicator of suicide risk. From the 18th February 2014 to the 23rd April 2014, Twitter was monitored for a series of suicide-related phrases and terms using the public Application Program Interface (API). Matching tweets were stored in a data annotation tool developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
