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、分類或推薦內容時，特別是規模很大時，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.(身后響起了汽車喇叭聲，看象人也用小鐵棒向他比劃著，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).(有關如何選擇相似度度量的更多信息，請訪問Mahout網站（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完成一些有趣的機器學習任務，這需要使用免費的Wikipedia數據集。)

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中的實現之前，我將從概念的層面上更加深入地討論這些任務。)

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