智能搜索大比拼：Siri不敵谷歌
|
????投資銀行Piper Jaffray的吉恩?蒙斯特非常嚴(yán)謹(jǐn)。大家排隊搶購蘋果（Apple）新產(chǎn)品時，他是那種會跑到現(xiàn)場清點人數(shù)的分析師。程序員們濟(jì)濟(jì)一堂，參加蘋果的開發(fā)者大會時，他又會攔下幾十號人，詢問他們是在為Mac、iPhone，還是Android設(shè)備開發(fā)應(yīng)用程序。 ????所以，當(dāng)明斯特想知道蘋果智能語音助手Siri和谷歌搜索究竟誰更厲害時，他（和他的助手）于是向iPhone提出了1,600個問題，其中800個是在明尼阿波利斯的繁忙嘈雜街道上進(jìn)行，另外800個則是在安靜的室內(nèi)。 ????Piper Jaffray在上周四致客戶的報告中公布了測試結(jié)果： ? 谷歌理解了100%的問題（這毫不意外，因為他們是打字輸入的問題） ? 谷歌回答的總計正確率是86% ? 在嘈雜的環(huán)境中，Siri理解了83%的問題；在安靜的室內(nèi)，這一數(shù)字為89% ? 在嘈雜的街道和安靜的室內(nèi)，Siri的正確率分別是62%和68%。 ????蒙斯特寫道：“如果想成為切實可靠的另一種移動搜索工具，Siri必須達(dá)到、超過谷歌目前的正確率B+，它必須從D提升到B，甚至更高的一檔?！?/p> ????雖然蒙斯特推測Siri在學(xué)習(xí)曲線上要比谷歌落后兩年以上，不過他十分樂觀：“隨著今年秋季iOS 6的推出，我們預(yù)計Siri將會取得顯著的進(jìn)步，而它對谷歌的依賴程度也將從目前的60%降至48%?！?/p> ????不過，鑒于測試結(jié)果，我們現(xiàn)在并不清楚減少Siri對谷歌的依賴性究竟是不是好事。 ????目前Siri的答案中，有60%來自谷歌，20%來自Yelp，14%來自計算數(shù)學(xué)應(yīng)用軟件開發(fā)商WolframAlpha，4%來自雅虎（Yahoo），另外2%則來自維基百科（Wikipedia）。 ????蒙斯特表示：“如果進(jìn)一步細(xì)分Siri的依賴關(guān)系，我們看到，谷歌提供了100%的導(dǎo)航結(jié)果、61%的信息結(jié)果、48%的商務(wù)結(jié)果和42%的本地結(jié)果。在其余搜索聚合商中，Yelp貢獻(xiàn)的本地結(jié)果（51%）和商務(wù)結(jié)果（51%）最多，而WolframAlpha則貢獻(xiàn)了34%的信息結(jié)果?！?/p> ????從今年秋天開始，蘋果將啟動自有地圖服務(wù)，對谷歌地圖的依賴將徹底成為歷史。而隨著雅虎體育、Open Table、爛番茄（Rotten Tomatoes）和Fandango等服務(wù)的整合，蘋果用戶將獲得體育比分與統(tǒng)計數(shù)據(jù)、餐廳預(yù)定、電影放映預(yù)告和票務(wù)等諸多服務(wù)。 ????蒙斯特將Siri所犯的錯誤進(jìn)行了分類，通過下面他提供的一些例子，我們可以看到Siri還有多長的路要走。 |
????Pi per Jaffray's Gene Munster is nothing if not methodical. When customers queue up for a new Apple (AAPL) product, he's the analyst who goes to the line and counts heads. When programmers gather at an Apple developers conference, he'll stop three or four dozen to ask if they are writing apps for Mac, iPhone or Android devices. ????So when he wanted to know how Siri stacked up against a Google (GOOG) search, he (or his staff) asked an iPhone 1,600 questions, 800 on the busy streets of Minneapolis, 800 in a quiet room. ????Piper Jaffray published the results Thursday in a note to clients: ? Google understands 100% of the questions (not surprisingly, since they are keyed in) ? Google replies accurately 86% of the time ? Siri comprehends 83% of queries in noisy conditions, 89% in a quiet room ? Siri answers accurately 62% of the time on the street and 68% in a quiet room. ????"In order to become a viable mobile search alternative," Munster writes, "Siri must match or surpass Google's accuracy of B+ and move from a grade D to a B or higher." ????He estimates that Siri is more than two years behind Google in its learning curve, but he's optimistic: "With the iOS 6 release in the fall, we expect Siri to improve meaningfully while reducing its reliance on Google from 60% to 48%." ????Given the results, however, it's not clear that reducing Siri's reliance on Google is necessarily a good thing. ????Currently Siri gets 60% of its answers from Google, 20% from Yelp, 14% from WolframAlpha, 4% from Yahoo and 2% from Wikipedia. ????"Breaking down Siri's reliance further," Munster writes, "Google provides 100% of navigation results, 61% of information results, 48% of commerce results and 42% of local results. Among other result aggregators, Yelp provided the most local results (51%) and commerce results (51%), while WolframAlpha provided 34% of information results." ????Starting in the fall, Apple's in-house maps will eliminate its reliance on Google for navigation and the integration of Yahoo Sports, Open Table, Rotten Tomatoes and Fandango will provide answers for sports scores and statistics, restaurant reservations, movie show times and ticket purchases. ????Breaking down the type of errors Siri makes, Munster provides some sample questions that demonstrate how far it has to go: |
