The next time you have a need to cluster, categorize, or recommend content, especially at large scale, give Apache Mahout a look.(下次在需要集群、分類或推薦內(nèi)容時，特別是規(guī)模很大時，一定要考慮使用ApacheMahout。)

Halfway up the hill, he saw an elephant coming down, with a small bundle of leaves on its back and a mahout poking its ear with an iron rod.(就在上到半山腰的時候，他看到了迎面走過來一頭大象，大象背上背著一小捆樹葉，旁邊看象人拿一根小鐵棒在撥弄著它的耳朵。)

Cars honked behind him. The mahout turned and gesticulated at him with his iron rod. A passerby yelled at him not to block traffic.(身后響起了汽車?yán)嚷暎聪笕艘灿眯¤F棒向他比劃著，一個過路人更對他吼著讓他不要妨礙交通。)

You'll find more information on choosing a similarity measure at the Mahout Web site (see Resources).(有關(guān)如何選擇相似度度量的更多信息，請訪問Mahout網(wǎng)站（見參考資料）。)

To do so, you need the Mahout Job JAR, which is located in the hadoop directory in the sample code.(為此，您需要MahoutJobJAR，它位于示例代碼的hadoop目錄中。)

“They didn’t pay me, ” the mahout said.(他們沒有付錢給我呢。)

Early one morning, Ladyface's mahout came to see him as usual.(一天清晨，“菩薩相”的看象人如常來看他。)

Then I'll show you how to use Mahout to do some interesting machine-learning tasks using the freely available Wikipedia data set.(然后，我將演示如何使用Mahout完成一些有趣的機(jī)器學(xué)習(xí)任務(wù)，這需要使用免費的Wikipedia數(shù)據(jù)集。)

I'll take a deeper look at each of these tasks at the conceptual level before exploring their implementations in Mahout.(在研究它們在Mahout中的實現(xiàn)之前，我將從概念的層面上更加深入地討論這些任務(wù)。)

Therein lies the premise and the promise of the field of machine learning and the project this article introduces: Apache Mahout (see Resources).(這其中就蘊(yùn)含著機(jī)器學(xué)習(xí)領(lǐng)域以及本文章所介紹項目的前景：ApacheMahout（見參考資料）。)
