Machine learning for suicidal ideation identification: A systematic literature review

作者:

Highlights:

• Suicidal ideation is the first stage in the risk scale, being a potential gate for suicide prevention.

• Studies explored mainly data from social media and investigated suicidal tendencies in the individuals' language.

• Deep learning models seem to be a tendency in this area nowadays, mainly when the task is text analysis.

• This review found a growing interest in suicidal ideation in the last years.

• This study summarizes machine learning techniques and current research challenges into two taxonomies.
