So now we're ready to think about how we should represent

それではWebコンテンツコーパスのインデックスをどのように表せばよいのかを

the index for our web content corpus.

考えていきましょう

And we're going to have a quiz to see if you can think of a good way to represent our index.

インデックスを表す最適な方法を考え出せるか確認するための小テストを行います

So I'm going to give you several options.

いくつか選択肢を用意しました

And try to decide which one you think would be the best way to represent our index.

インデックスを表す最適な方法だと思うものを 1つ選んでください

And I should note that several of these could work.

有効なものは複数あります

We could build a search index using different data structures,

異なるデータ構造を使用して検索インデックスを作成します

and if we tried hard enough, we could make many of these possibilities work.

これらの選択肢からいろいろな可能性を導き出せるかもしれませんが

But I want you to think hard about what's going to be the best one to use.

ここでは運用に最も適しているものをよく考え選んでください

So the first option is we could have a single list

1つ目の選択肢はキーワードに続いて

where we have a keyword followed by the URLs where that keyword appears

そのキーワードが現れるURLと続いてもう1つのキーワードがあり

followed by another keyword followed by the URLs where that keyword appears.

それに続いて別のキーワードが現れるURLとなっている1つのリスト

The second option would be we would have a list

2つ目の選択肢は

containing as its elements lists.

その要素リストが含まれているリスト

And each element would be a list of the keyword followed by the URLs where that keyword appears.

各要素はキーワードに続いてキーワードが現れるURLのリストになっているもの

The third option, we could have a list where each element of the list is a list where the first element is the URL,

3つ目の選択肢はリストの要素1つ1つがリストでその1つ目の要素がURLであり

and the second element is a list of all the keywords that are found on that page.

2つ目の要素がページ上で見つかったすべてのキーワードのリストになっているリスト

The fourth choice is a list where each element is a list and each element list is a keyword followed by a list of all the URLs that contain that keyword.

4つ目の選択肢はそれぞれの要素がリストになっているリストで各要素リストはキーワードに続くキーワードを含んだすべてのURLのリストになっているもの

So see if you can decide which one of these four representations

この4つから最適な表現を選んでください

will be the best one to use to represent the index for our web content corpus.
