Facebook tracking suicide-tied posts The social media site is providing researchers at the suicide prevention group Save.org a glimpse of how those who take their own lives behave in the days leading up to their deaths, as outlined in their Facebook postings. Dan Reidenberg, executive director of Save and a national leader in the counseling field, expects the information will one day help friends, family and social media sites better identify warning signs in the words and actions that lead up to suicide. The Jan. 11 death of Internet activist Aaron Swartz, the latest casualty in a series of high-profile suicides in the technology industry over a decade, has spurred new interest in understanding the triggers that compel people to cut their own lives short. Google's search engine, meanwhile, has been designed to bring up the phone number for the National Suicide Prevention Lifeline for any searches on "suicide" or related terms, said Jay Nancarrow, a spokesman for the Mountain View company. A partnership formsSocial media's partnership with suicide experts started in the summer of 2010, after a cluster of suicides in Palo Alto set the industry on edge, Reidenberg said. In 2010, representatives of Facebook, Google and San Francisco's Twitter met with medical experts from the National Suicide Prevention Lifeline about what they could do to help. [...] the company will help independent researchers analyze patterns that may reveal how people approach their decisions to commit suicide. The research will allow investigators to track such language online without having to depend on the memories of survivors or friends.
