Siri補考有進步
????Siri有點像天氣。人人嘴上都愛抱怨它,但只有投資銀行Piper Jaffray的吉恩?蒙斯特真正采取了行動。 ????今年六月,蒙斯特測試了iOS 5版本的蘋果(Apple)聲控個人助理Siri。他向Siri問了1,600個問題,其中有800個問題是在美國明尼阿波里斯市的街頭問的,而另外800個則是在一間安靜的房間中問的。 ????結果顯示Siri尚有很大的改進空間。在最理想的情況下(即沒有街道噪音),Siri正確理解了89%的問題,正確回答了68%的問題。(一個很典型的例子是,Siri聽見問:下次哈雷彗星出現是什么時候?它的回答是:“您沒有安排與哈利會面。” ????上周四,明斯特報道了在安靜的房間(沒有街道噪音)里對“改進后的”iOS 6版Siri再度進行測試的結果。這一次,Siri理解了91%的問題,并正確回答了77%的問題。 ????按照學校的打分標準,Siri的得分從D提高到了C。 ????(明斯特沒有解釋他為何將Siri在六月份的正確率從68%調高到了76%,從而使得iOS 6版Siri的進步看起來小了很多。或許他現在是按正態曲線評分了。) |
????Siri is a little like the weather. Everybody complains about it, but only Piper Jaffray's Gene Munster seems to do anything. ????In June he put the iOS 5 version of Apple's (AAPL) voice-activated personal assistant to the test -- asking her 1,600 questions,800 in the streets of Minneapolis and 800 in a quiet room. ????The results left much to be desired. In the best of circumstances (i.e. no street noise), Siri correctly interpreted 89% of the questions and correctly answered 68%. (Typical exchange, as Siri heard it: When is the next Haley's comment? "You have no meetings matching Haley's".) ????On Thursday, Munster reported the results of a quiet-room (no street noise) re-test of the "improved" iOS 6 version. This time Siri understood 91% of the questions and correctly answered 77%. ????In school-grade terms, she's gone from a D to a C. ????(For reasons Munster doesn't explain, he's raised Siri's June score from 68% to 76%, making the improvement look more modest than it was. Perhaps he's now grading on a curve.) |
