原文(续[03-10])
The advantages of AI are most visible in firms’ predictions of what users want. Automated recommendations and suggestions are responsible for around three-quarters of what people watch on Netflix, for example, and more than a third of what people buy on Amazon. Facebook, which owns the popular app Instagram, uses machine learning to recognise the content of posts, photos and videos and display relevant ones to users, as well as filter out spam. In the past it ranked posts chronologically, but serving up posts and ads by relevance keeps users more engaged.
AI的优势在企业预测用户需求时最为明显。例如,人们在Netflix上观看内容的约四分之三、在亚马逊网站购买商品超过三分之一都来自系统自动推荐或建议。拥有流行应用Instagram的 Facebook利用机器学习来识别贴文、照片和视频的内容,向用户展示关联内容的同时过滤垃圾信息。过去它是按照时间顺序排列帖文,但现在是依照与用户的相关性排列帖子和显示广告,提高了用户参与度。
词汇讲解
· automated
automated指“自动化的”或“机械化的”,即通过电脑或机械来完成工作,而不是通过人力 (using computers and machines to do a job, rather than people)。它常见的搭配有highly automated和fully automated
· a highly automated factory
· The production process is now fully automated.
automated很明显来自automate,而automate来自automation的逆构词,而automation来自automatic
· “逆构词”(back formation) 即指从已存在的词中去掉一个词缀所形成的新词。
· televise来自television
· vacuum clean来自vacuum cleaner
· burgle来自burglar
· automated recommendations and suggestions
recommendation和suggestion是一对同义词。
相关同义词拓展
advice, opinion, suggestion, recommendation, view这些名词都可以表达“意见”或者“建议”。
· advice普通用词,侧重依据个人经验、学识和正确判断而提出的忠言。
· opinion日常用词,泛指对某事物的想法和意见。
· suggestion普通用词,语气比advice婉转客气,也不如proposal正式。着重为改进工作、解决困难等提出的建议,有时含所提建议不一定正确,仅供参考的意味。
· recommendation指在自己经历的基础上而提出的有益建议、意见或忠告。
· view侧重对重大的或引起公众关注的问题所持的看法和态度。
· own
文中释义:拥有
own在文中这里是表示“有”、“领有”、“拥有”这类的常用含义,我在这里补充一个own的熟词僻义:own作动词使用的时候还可以包含acknowledge的含义,表示“承认(过错)”,该用法下常见的搭配是own up (to sth)
· Nobody owned up to the theft. 这件偷窃事没有人承认是自己干的.
· Eventually she owned up. 她终于认错了
· When confronted with the evidence the thief owned up. 在证据面前小偷乖乖地招认了
· filter out [filter sth⇔out]
filter本义指“过滤器
