[ti:Facebook Uses Artificial Intelligence to Fight Suicide] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.12]Facebook says it has successfully tested a computer program [00:05.48]that can help keep users from taking their own lives. [00:11.28]The social media network now says it will expand the use of [00:17.16]the pattern recognition software to other countries. [00:23.52]Facebook began testing the software in the United States in March. [00:30.84]The software is considered an example of artificial intelligence. [00:37.32]In February, Facebook chief Mark Zuckerberg wrote in a statement [00:43.60]that artificial intelligence could be used to help keep people safe. [00:50.84]The software scans messages on Facebook for comments [00:56.64]that could be signs that a person intends to harm themselves. [01:01.56]Facebook has not released any of the technical details about the program. [01:10.52]But, the company did say that it looks for phrases [01:14.72]such as "Are you ok?" and "Can I help?" [01:20.96]If the software finds the signs it is looking for, [01:25.36]it alerts a team of Facebook workers [01:28.96]who specialize in dealing with such reports. [01:35.04]The system suggests resources to the user [01:39.44]or to friends of the person such as a telephone help line. [01:46.52]Facebook workers sometimes call local officials to take action. [01:53.72]Facebook said it tries to have specialists available [01:58.36]at any hour to call officials in local languages. [02:04.08]Guy Rosen is Facebook's vice president for product management. [02:10.52]He posted a description of the program on the Facebook website on Monday. [02:18.08]He said the company was expanding use of the software [02:22.60]because the tests were successful. [02:26.80]He said first responders checked on people more than 100 times [02:33.24]after Facebook's software raised alarms. [02:38.52]Reuters reported that Rosen said, "Speed really matters. [02:44.20]We have to get help in real time." [02:48.56]Facebook started to use the new software [02:52.04]after the launch of live video broadcasting in 2016. [02:58.68]A number of incidents took place in which people were live [03:03.56]broadcasting violent acts including suicides and murders. [03:10.24]In May, the company said it would hire 3,000 people to monitor video and other content. [03:20.56]Rosen did not say where Facebook would use the software outside the U.S. [03:27.76]He said, in time, it would be used around the world except in the European Union [03:35.24]where privacy laws would likely place limits on its use. [03:41.96]Google is another technology company that tries to prevent suicides by monitoring users. [03:52.08]The Google search engine will show a hot line telephone number [03:57.44]if certain searches are made. [04:01.48]Facebook uses information from its users to target advertising. [04:08.44]The company has not announced in the past that it scans messages for harmful behavior. [04:17.40]However, the company says it does look for suspicious comments [04:23.08]between children and adult sex criminals. [04:28.12]Facebook says sometimes it contacts officials when it finds targeted discussions. [04:37.68]Ryan Calo is a law professor at the University of Washington. [04:44.32]He says scanning people's discussions is harder to justify in other situations. [04:52.88]Calo said, "Once you open the door, [04:56.68]you might wonder what other kinds of things we would be looking for." [05:03.64]Rosen declined to comment about whether Facebook [05:07.48]is considering pattern recognition software to fight non-sex related crimes. [05:16.08]The company announced that it was using technology and other resources [05:21.76]to help save lives on September 7, World Suicide Prevention day. [05:30.08]I'm Mario Ritter. 更多听力请访问51VOA.COM
