While it may be unlikely for a computer to write a best seller, a technology expert has created a computer program that writes its own fiction stories with minimal user input. The program, called MEXICA, is the first to generate original stories based on computerized representations of emotions and tensions between characters.

    An Internet survey was carried out to see the popularity of the computer-generated stories, other computerized stories and stories written solely by a human. The result was that readers ranked MEXICA stories highest for flow and coherence, structure, content, suspense and overall quality. Rafael Pérezy Pérez, the creator of MEXICA, explained that a story might begin with something as basic as, “The enemy wounded the knight. The princess cured the knight. The knight killed the enemy. The knight rewarded the princess. The end.”

    The program reads characters as variables (变量) and assigns a numerical value, between a continuum (连续体) from -3 to +3, to emotional connections that are defined as either amorous or non-amorous. The numerical value is equivalent to the degree of emotion, with -3 being intense hate and +3 being intense love. The program also understands story tension, such as linking the word “wounded” with tension. This too is assigned a numerical value.

    Once these clusters of emotional links and tensions are established, the program begins what is called an “engagement reflection cycle”. Basically this involves searching a database of story actions and other happenings, which are called “atoms”, and determines the best match for the characters and contexts for that moment.

    The process repeats itself again and again until the system can no longer make any matches. At this point, the computer analyzes the story for coherence and “interestingness”. The program views a story as interesting when tension levels increase and fall throughout the piece. If the program finds that the story is boring or incoherent in places, it will replace or insert atoms until a version is thought to be satisfactory.

    When Wu Jia, then aged 23, returned from Canada to work for her father's Hangzhou-based Zoland Animation (动画) in 2007, she found Chinese animation productions were just-so-so. Back then, Chinese animation shown at overseas events, received a poor response.

    But things soon changed following a boom in China's movie and television industries. By 2011, China developed into one of the world's largest animation producers, with animation and cartoon products reaching a record of 260,000 minutes.

    However, that figure has witnessed a fall in recent years. The latest statistics show that China made only 244 animated productions totaling 83,600 minutes in 2017. But Wu says: “Chinese animators are changing from quantity to quality and Chinese animators are now producing more quality works” at the 14th China International Cartoon & Animation Festival.

    Wu, now the chairman of Zoland Animation, is among those who are part of China's rapidly growing animation industry. She says the company has so far displayed more than 8,000 hours of animated content to 93 countries and regions, including the United States, United Kingdom, France, South Korea and Russia.

    Magic Eye, one of Zoland's most popular animated works, which was sold to just Singapore in 2006, is now reaching the screens of nearly 80 countries and regions worldwide. The 500-episode animated series about an alien boy's adventures on Earth also has a sequel (续集) series Magic Eye is Back, which has 104 episodes. Thanks to Magic Eye's popularity, the sequel quickly arouses interest in overseas markets and is being displayed in 38 countries and regions.

    Speaking about how to succeed abroad, Wu says: “First, the works should be good. And, you need an experienced team who knows international markets.”

    When people see machines that respond like humans, or computers that perform amazing feats of strategy, they sometimes joke about a future in which humanity will need to accept robot overlords. But buried in the joke is a seed of unease. Science fiction writing and popular movies have shown us about artificial intelligence (AI) that exceeds the expectations of its creators and escapes their control, eventually outcompeting and enslaving humans or targeting them for extinction(灭绝).

    Even in the real word, not everyone is ready to welcome AI with open arms. In recent years, as computer scientists have pushed the boundaries of what AI can accomplish, leading figures in technology and science have warmed about the frightening dangers that artificial intelligence may pose to humanity, even suggesting that AI capabilities could destroy the human race.

    But why are people so frightened about the idea of AI?

    Elon Musk is one of the famous voices that have raised red flags about AI, In July 2017. Musk told attendees at a meeting of the National Governors Association, I have exposured to the very cutting-edge Al, and I think people should be really concerned about it. I keep sounding the alarm bell. But until people see robots going down the street killing people, they don't know how to react, because it seems so impossible."

    Earlier, in 2014, Musk had labeled AI "our biggest existential threat," and in August 2017, he declared that humanity faced a greater risk from AI than the terrorists. Physicist Stephen Hawking, who died on March14, also expressed concerns about AI, telling the BBC in 2014 that "the development of full artificial intelligence could spell the end of the human race.

    The Bermuda Triangle is an area in the western part of the North Atlantic Ocean, near Florida in the USA, where a number of aircraft and ships are said to have disappeared mysteriously.

    ①The earliest suggestion of unusual disappearances in the Bermuda area appeared in a September 17, 1950 article. Two years later, published "Sea Mystery at Our Back Door", covering the loss of several planes and ships, including the loss of Flight 19. Flight 19 alone would be covered again in the April 1962 issue of American Legion magazine. In it, author Allan W. Eckert wrote that the flight leader had been heard saying, "We are entering white water. Nothing seems right. We don't know where we are." In the February 1964, the article "The Deadly Bermuda Triangle" argued that Flight 19 and other disappearances were just part of strange events in the area.

    ②Triangle writers have used a number of supernatural ideas to explain the events. One explanation refers to leftover technology from the mysterious lost continent of Atlantis. Some of the Triangle writers related the events to UFOs. This idea was used by Steven Spielberg for his science fiction film Close Encounters of the Third Kind, in which the lost Flight 19 aircrews were taken by aliens.

    ③But there are also some explanation relating to nature. For example, laboratory experiments carried out in Australia have proven that bubbles containing natural gas can sink a large ship by decreasing the density(密度) of the water. Because it has been assumed that the eruption of volcanoes(火山)may produce much natural gas, making large areas of bubbles under sea so that water is no longer able to provide enough supporting power for ships. If this were the case, such an area forming around a ship could cause it to sink very rapidly and without any warning.

    ④Violent weather is likely to be another reason. Powerful storms forming in tropical(热带的)waters have caused thousands of deaths and caused billions of dollars in damage. These storms have in the past caused a number of incidents related to the Triangle.

Friends play an important part in our lives, and although we may take friendship for granted, we often don't clearly understand how to make friends. While we get on well with a number of people, we are usually friends with only a very few — for example, the average among students is about 6 per person. In all the cases of friendly relationships, two people like one another and enjoy being together, but beyond that, the degree of intimacy between them and the reasons for their shared interests vary greatly. As we get to know people, we take into account things like age, race, economic condition, social position, and intelligence. Although these factors are not of great importance, it is more difficult to get on with people when there is a marked difference in age and background.

Some friendly relationships can be kept on argument and discussion, but it is usual for close friends to have similar ideas and beliefs, the same opinions and interests — they often talk about "being on the same wavelength". It generally takes time to reach this point. And the more intimately involved people become, the more they depend on one another. People who want to be friends have to learn to put up with annoying habits and to stand differences.

In contrast with marriage, there are no friendship ceremonies to strengthen the association between two people. But the supporting and understanding of each other that results from shared experiences and emotions does seem to create a powerful bond, which can overcome differences in background, and break down barriers of age, class or race.
