From Facebook chief security officer Alex Stamos to former Microsoft Corp chief executive Steve Ballmer, US tech executives have sought in recent days to dispel the notion there is a swift solution to the proliferation of spurious or insidious information on the Internet, a phenomenon critics said wields an outsized and unhealthy influence on public discourse and elections.
Baidu Inc (百度) president Zhang Yaqin (張亞勤) said China faces similar challenges, despite operating one of the world’s largest and most sophisticated online surveillance machines.
Companies in China, where freedom of speech is curtailed by censorship programs, have long used a mix of advanced technologies and human cybercops to police the Internet.
Baidu, China’s largest search engine, employs technology to spot potentially false information before turning to local agencies such as the Cyberspace Administration of China to verify items. One of the country’s three largest Internet players, it checks 3 billion claims of fake news every year.
“Every year we see somewhere around 3 billion claims, requests that we need to verify that might turn out to be fake news,” Zhang said. “We’re using a combination of technology and content authorization to minimize the fake news.”
From Tencent Holdings Ltd (騰訊) to Sina Corp’s (新浪) Weibo (微博), China’s social media employ technology and armies of vetters to scour its services for undesirable content, which goes beyond rumors and unsubstantiated claims to include any and all information deemed harmful to social stability.
Yet, even the best-funded online operators have difficulty keeping up: China’s cybercops last month fined Tencent, Weibo and Baidu for carrying illegal content.
Days later, Weibo began recruiting and rewarding “supervisors” from among its own users to report problems.
“We have an obligation to make sure the user gets good content, but it continues to be a challenge for us, for other companies in China and companies in the US,” Zhang said.
The problem persists despite China having some of the strictest rules aimed at preventing the spread of “false news.”
It recently established regulations forcing forum-posters to register with their real identities and its laws threaten jail time for posting defamatory false information, Weibo’s latest annual report said.
However, Zhang said fixing the problem required the use of advanced technologies like artificial intelligence and even closer cooperation with relevant government regulators.
Pressure is building on social media services from Google to Twitter to try and curb the proliferation of fake news and targeted ads.
Stamos last week said it was very difficult to spot fake news and propaganda using computer programs.
Executives from Alphabet Inc’s Google, Facebook Inc and Twitter Inc are scheduled to testify before US Congress on Nov. 1 about Russian use of their sites to influence last year’s US presidential election — a hot-button topic that the social media and Internet services are under pressure to address.
Stamos, who is handling Facebook’s investigation, said that technical solutions could have unintended consequences of ideological bias.
“I’m not sure you can say that is Facebook’s job, they’re not in the news business, they pass along other people’s news,” Ballmer said. “Same thing with Google. ”
SECOND-RATE: Models distilled from US products do not perform the same as the original and undo measures that ensure the systems are neutral, the US’ cable said The US Department of State has ordered a global push to bring attention to what it said are widespread efforts by Chinese companies, including artificial intelligence (AI) start-up DeepSeek (深度求索), to steal intellectual property from US AI labs, according to a diplomatic cable. The cable, dated Friday and sent to diplomatic and consular posts around the world, instructs diplomatic staff to speak to their foreign counterparts about “concerns over adversaries’ extraction and distillation of US AI models.” Distillation is the process of training smaller AI models using output from larger, more expensive ones to lower the costs of training a powerful new
Singapore-based ride-hailing and delivery giant Grab Holdings’ planned acquisition of Foodpanda’s Taiwan operations has yet to enter the formal review stage, as regulators await supplementary documents, the Fair Trade Commission (FTC) said yesterday. Acting FTC Chairman Chen Chih-min (陳志民) told the legislature’s Economics Committee that although Grab submitted its application on March 27, the case has not been officially accepted because required materials remain incomplete. Once the filing is finalized, the FTC would launch a formal probe into the deal, focusing on issues such as cross-shareholding and potential restrictions on market competition, Chen told lawmakers. Grab last month announced that it would acquire
The artificial intelligence (AI) boom has triggered a seismic reshuffling of global equity markets, with Taiwan and South Korea muscling past European nations one by one. With its stock market now valued at nearly US$4.3 trillion, Taiwan surpassed the UK, Europe’s biggest market, earlier this month, data compiled by Bloomberg showed. South Korea is about US$140 billion away from doing the same. The tech-heavy Asian markets have shot past Germany and France in the past seven months. The shift is largely down to massive gains in shares of three companies that provide essential hardware for AI: Taiwan Semiconductor Manufacturing Co (TSMC, 台積電),
Shares of Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) have repeatedly hit new highs, but an equity analyst said the stock’s valuation remains within a reasonable range and any pullback would likely be technical. The contract chipmaker’s historical price-to-earnings (P/E) ratio has ranged between 20 and 30, Cathay Futures Consultant Co (國泰證期) analyst Tsai Ming-han (蔡明翰) told Central News Agency. With market consensus projecting that TSMC would post earnings per share of about NT$100 (US$3.17) this year, supported by strong global demand for artificial intelligence (AI) applications, and the stock currently trading at a P/E ratio of below 25, Tsai said the valuation
