Scientists at Canada's University of Alberta (UAlberta) have created a machine learning model that can identify linguistic clues indicating early signs of depression in written text, like Twitter messages.

The team developed the English-language model from writing samples by individuals who identify as depressed in online depression forums; the algorithm was trained to detect depressive language in tweets.

UAlberta's Nawshad Farruque said, "This is the first study to show that depressive language has a specific linguistic representation. We demonstrate that it is possible to identify it, transfer it, and further use it for depressive language detection tasks."
