  • Welcome to CS101. I'm Dave Evans, I will be your guide on this journey.

    歡迎來到 CS101 課程, 我是 Dave Evan, 是你們這趟旅程的指導老師

  • This course will introduce you to the fundamental ideas in computing

    這門課將向你介紹計算的基本觀念

  • and teach you to read and write your own computer programs.

    教你如何讀寫你自己的電腦程式

  • We are going to do that in the context of building a web search engine.

    我們要透過建立網路搜尋引擎的來龍去脈,來進行講解

  • I'm guessing everyone here has at least used a search engine before.

    我猜想這裡的每個人至少曾用過一種搜尋引擎

  • Like Google, DuckDuckGo or even my personal favorite - DaveDaveFind.

    像是 Google、 DuckDuckGo, 或是我個人最喜歡的 DaveDaveFind

  • You type in what you are looking for, and voila -

    當你敲入要搜尋的內容,瞧

  • in literally a blink of an eye, about a tenth of a second, back come the results.

    幾乎一眨眼的功夫,大概十分之一秒,就得到了結果

  • This might not be enough to make you wise, but it is pretty amazing.

    這可能不足以讓你變聰明,但真的很神奇

  • A goal of this class is to turn some of the magic of the search engine

    這門課的目的就是要將神奇的搜尋引擎

  • into something a bit more understandable.

    變得更容易理解

  • Our biggest goal tho is to learn about computer science.

    我們的最主要目標是學習電腦科學

  • Computer science is about how to solve problems,

    電腦科學是關於如何解決問題

  • like building a search engine,

    像是建立一個搜尋引擎

  • by breaking them into smaller pieces

    將它分解成幾個小部分

  • and then precisely and mechanically describing a sequence of steps that you can use to solve each piece.

    然後準確並機械式地描述,解決每個部分的一連串步驟

  • And those steps can be executed by a computer.

    並由電腦來執行這些步驟

  • For our search engine the three main pieces are:

    我們的搜尋引擎有三個主要部分:

  • finding data by crawling web pages,

    透過爬行網頁來收集資料

  • building an index to be able to respond quickly to search queries,

    建立索引,以便能夠快速地對查詢做出回應

  • and ranking pages so that we get the best result for a given query.

    為網頁排序,對查詢取得最好的結果

  • In this course we will not get into everything that you need

    這門課不會對如何建立像 Google

  • to build a search engine as powerful as Google,

    這麼強大的搜尋引擎做詳細的介紹

  • but we will cover the main ideas and learn a lot about computer science along the way.

    但會涵蓋主要的觀念, 並同時學習大量的電腦科學知識

  • The first three units will focus on building the web crawler.

    前三個單元的重點在於如何建立網頁蜘蛛

  • We will talk more about that soon.

    我們很快地會討論更多這方面的知識

  • Units 4 and 5 will cover how to respond to queries quickly.

    第四和第五單元,將涵蓋如何快速地回應查詢

  • And unit 6 will get into how to rank results

    第六單元會介紹如何為結果排序

  • and cover the method Google uses to rank pages, that made it so successful.

    涵蓋了 Google 所使用的網頁排序方法, 這個方法使得 Google 如此的成功

  • But first, let's talk about how to build a web crawler

    但首先,我們來談談如何建立網頁蜘蛛

  • that we are going to use to get data for our search engine.

    它將為搜尋引擎收集資料
