Linked is a web platform that measures the frequency and density of friendship and social ties around the world, a type of data that has rarely been made available to those interested in understanding how relationships affect social outcomes. Our platform leverages Twitter interactions to determine connectedness and social ties between users. These connections provide insights which can be pivotal in times of crisis – particularly when contact needs to be established.

Linked is currently accessible for free to Mental Health Organisations and Foundations, who can use it to reach out to Twitter users that post suicidal or mental health distress messages. The platform is also able to identify connections that can be contacted in times of emergencies with 87% accuracy
