Artificial intelligence programs built by China's e-commerce titan Alibaba scored better than humans on a Stanford University reading and comprehension test.


"This is the first time that a machine has outperformed humans on such a test Roberto Alomar Youth Jersey ," Alibaba said in a statement on Monday.


The test was designed by artificial intelligence experts at Stanford to measure computers' growing reading abilities. Alibaba's software was the first to beat the human race.


Luo Si, chief scientist for natural language processing at Alibaba's AI research arm, called the milestone "a great honor," but also acknowledged that it is likely to lead to a significant number of workers losing their jobs to machines.


The technology "can be gradually applied to numerous applications such as customer service, museum tutorials and online responses to medical inquiries from patients, decreasing the need for human input in an unprecedented way," Si said in a statement.


Alibaba has already employed the underlying technology in its November 11 shopping festival over the years, using computers to answer a large number of customer service questions, the company said.


Pranav Rajpurkar, one of the Stanford researchers who developed the reading test, said in a tweet that Alibaba's feat is "a great start to 2018" for artificial intelligence.


Based on more than 500 Wikipedia articles, the Stanford quiz asks the AI to provide exact answers to more than 100,000 questions, testing its ability to process large amounts of information before supplying precise answers to queries. It is considered one of the world's most authoritative machine-reading gauges and has previously attracted companies such as Google, Facebook, IBM, Tencent and Samsung.


The deep neural network model developed by Alibaba scored 82.44 on the test last week, narrowly beating the 82.304 achieved by human participants. A day later, Microsoft's AI software scored 82.650 on the same test.


"That means objective questions such as 'what causes rain' can now be answered with high accuracy by machines," Si said.


China's technology firms Tencent and Baidu are also competing to develop AI that can enrich social media feeds, target ads and services or even aid autonomous driving.


China has stressed innovation in its 13th Five-Year Plan (2016-2020), with an aim to become an "innovation nation" by 2020, an international leader in innovation by 2030, and a world powerhouse in scientific and technological innovation by 2050.


BEIJING, Dec. 20 (Xinhua) -- The U.S. national security strategy unveiled by President Donald Trump Monday has raised concerns worldwide with the international community calling it confrontational and contradictory and displaying an outdated Cold War mentality.


CONFRONTATIONAL, NOT CONSTRUCTIVE


Instead of promoting cooperation between countries, the new security strategy sparks confrontation in the global community and hampers constructive resolution of pressing international issues, the Russian Foreign Ministry said in a statement Tuesday.


"Its key message - 'to preserve peace through strength' - sets the line not for constructive cooperation with other countries on an equal basis and in the interests of a joint resolution of existing problems, but for confrontation," the statement read.


The ministry said the plan of action outlined in the strategy clearly demonstrated Washington's strive to retain its weakened domination and superiority in the global arena by all means.


A Kremlin spokesperson called the strategy "imperial". "There is a persistent reluctance to renounce the concept of a unipolar world, as well as rejection of a multipolar world," spokesperson Dmitry Peskov said.


"Destabilizing policies and actions by some countries to maintain their hegemony in pursuit of absolute power are responsible for instability in several parts of the world, including ours," the Pakistani Foreign Ministry said in a statement.


Selcuk Colakoglu, director of the Turkish Center for Asia Pacific Studies, said the U.S. strategy indicates a more confrontational approach toward Russia, China, Iran and the Democratic People's Republic of Korea.


GAP BETWEEN TRUMP'S STRATEGY AND ACTION


The media and experts pointed out that Trump himself did not seem to be totally buying the new national security strategy himself. The president's viewpoint seemed to differ from that of his establishment-minded foreign policy advisors.


The Atlantic magazine said on Wednesday that's Trump's speech unveiling the strategy "butchered it in a revealing way." The strategy declares that the Trump administration will pursue a "strategy of principled realism." But what Trump said was, "Our new strategy is based on a principle, realism."


Also, the strategy presented Russia as a power bent on undermining U.S. interests and meddling in the U.S. presidential race last year. But in his speech, Trump did not mention the alleged Russian intervention in the election he won. Instead, he talked about a phone call from his Russian counterpart Vladimir Putin, mentioning how the latter had thanked him for providing intelligence to foil a major terror attack in Russia.


"Trump's speech highlighted the gap between his theories and his actions," said Norhan al-Sheikh, professor of international relations at Cairo University. "His speech is contradictory. He seems to be dealing with a hypothetical world."


After calling Russia and China two "revisionist" powers seeking to undermine U.S. influence, values and interests, Trump immediately called for building a "great partnership" with them, al-Sheikh pointed out.


Moreover, Trump demanded that NATO allies contribute more to the cost of protecting Europe, threatening to retreat otherwise. But his administration has been vowing to restore the U.S. presence in the international area
