Samaritans Radar analyses Twitter to identify users at risk for suicide

Samaritans Radar is a web app that works across various devices.

Excerpt from this article:

Samaritans Radar launched today as a website that will “flag potentially worrying tweets that you may have missed” once Twitter users register their details.

Developed by digital agency Jam, the service will analyse tweets for phrases and keywords that may indicate someone is at risk for suicide, then email friends registered with Samaritans Radar with advice on how to help.The phrases include “tired of being alone”, “hate myself”, “depressed”, “help me” and “need someone to talk to”, although Samaritans admits that the algorithm is likely to evolve over the coming months, to avoid false positives.
