[ti:Facebook Likes Can Tell a Lot About You] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.16]Facebook "likes" can tell a lot about a person. [00:05.36]In a 2013 study, researchers showed they could use Facebook "likes" [00:11.48]to correctly predict personal information, [00:14.92]including a user's sexual identity and ethnicity. [00:20.76]The researchers could also predict a person's age, intelligence, [00:26.12]and opinions about religion and politics. [00:30.92]They could identify whether someone is happy [00:34.16]or used addictive substances. [00:38.12]They could even predict whether an individual's parents would stay together [00:43.12]until the person turned 21 years old. [00:47.84]The study was based on information from 58,000 volunteers [00:53.51]who provided "likes" to Facebook, the American social media company. [01:00.32]The findings were published in Proceedings of the National Academy of Sciences. [01:07.40]The researchers used computer programs to look for hard-to-establish patterns, [01:13.92]such as a link between a love for curly fries and higher intelligence. [01:20.28]The 2013 study found that Facebook users who rated high on Openness [01:26.40]often liked Hello Kitty brand products. [01:30.32]They also were more likely to be of African-American ancestry [01:35.28]and support Democratic Party values. [01:39.52]Many businesses urge people to log on to their websites [01:43.84]with Facebook or other social media accounts. [01:48.20]This, in turn, provides companies with a complete picture of the user's birthday, [01:54.12]list of friends, schools attended and other personal information. [02:00.84]Marketers often use Facebook "likes" and other digital records [02:06.13]to sell products and improve services. [02:10.88]The researchers warned about the possible misuse of digital records and personal information. [02:18.52]They said marketers can collect information about large numbers of people [02:23.96]without asking for their approval and without them noticing. [02:29.40]They said companies, governmental agencies, or even one's Facebook friends [02:35.24]could gather data that an individual may not have wanted to share. [02:41.36]Last week, Facebook reported that a private company called Cambridge Analytica [02:47.32]did just that with data from its social media website. [02:52.64]Facebook said Cambridge Analytica collected private information, [02:57.48]including Facebook "likes," from more than 50 million Facebook users. [03:04.04]It said the company got the information from 270,000 people [03:09.17]who downloaded a software program described as a personality test. [03:15.28]Those individuals agreed to share personal information for a study. [03:21.40]A researcher also took the information of all their Facebook friends, [03:26.56]a move that was permitted under Facebook's rules until 2015. [03:32.76]The researcher then sold the information to Cambridge Analytica, [03:37.28]which used the data during the 2016 election campaign in the United States. [03:44.16]The company worked for then candidate Donald Trump. [03:49.04]However, a Trump campaign official said the campaign used Republican data sources, [03:55.56]not Cambridge Analytica, for voter information. [04:00.88]Facebook suspended Cambridge Analytica for violating its rule. [04:06.40]And it was considering legal action against the company. [04:12.08]Those measures might not be enough to satisfy U.S. and British officials. [04:19.36]Britain's Information Commissioner Elizabeth Denham [04:23.12]said she is seeking permission to search Cambridge Analytica's London headquarters. [04:30.12]She wanted to see whether Facebook did enough [04:33.17]to protect users' personal information about themselves and their friends. [04:39.56]Several U.S. lawmakers want Facebook chief Mark Zuckerberg [04:44.48]to speak to Congress about the use of its users' information. 更多听力请访问51VOA.COM
