There’s just one hitch: the system still needs guinea pigs. Even the best weather models can’t pinpoint where clear-air turbulence will occur. So the NCAR programs continue to rely on firsthand reports from planes that have already been tossed around. New technologies could change that in coming years. A plane equipped with a lidar sensor—which uses lasers to detect much finer particles than radar can—could pick up on turbulence even in a cloudless sky. But lidar systems are still too bulky and expensive to fit into a plane’s nose cone. And the government and the airline industry have been slow to invest in improving them. For now, the best hope for a flight heading into turbulence might be to program the plane itself to ride the bumps.
机器先看的是结构。YouTube的内容长得都差不多：有标题、有简介、有标签，有时还有清晰的时间轴和章节。标题往往就是一个问题或主题，简介相当于摘要和补充说明，标签和分类是现成的语义标记，章节和时间点把一条长视频切成若干段。
