Wikipedia article depth/ja

ウィキペディアにおいて、深さ (depth) または編集の深さ (edition depth) は、プロジェクトにおいて記事の更新頻度を示し、百科事典の共同性を計る、ざっくりとしているかもしれない指標のひとつです。この指標は計算不可能な学術的価値を示すものではありませんが、ウィキペディアンの質を示すことはできます。

定義

この式は、編集回数と記事数が記事の更新の頻度に関係している、という仮定の下にあります。また、後者の記事数はより重要な要素だと仮定されています。

ウィキペディアの一覧では、深さを以下のように定義しています:

${\text{深 さ}}={\frac {\text{編 集 回 数}}{\text{記 事 数}}}\cdot {\frac {\text{記 事 以 外}}{\text{記 事}}}\cdot \left(1-{\frac {\text{記 事}}{\text{合 計}}}\right)$

深さは以下の等価な式で簡略化することもできます:

${\text{深 さ}}={\frac {\text{編 集 回 数}}{\text{合 計}}}\cdot \left({\frac {\text{記 事 以 外}}{\text{記 事}}}\right)^{2}$

記事以外は、利用者ページ、リダイレクト、ファイル、プロジェクトページ、カテゴリ、テンプレートとこれらに付属するノートページを示します。合計は記事と記事以外の和です。

現在の英語版ウィキペディアの深さは20.31 × 63.53 = 1290で、この深さは1万記事以上を有するプロジェクトにおいてもっとも大きな数字となっています。なお、日本語版ウィキペディアの深さは24.31 × 3.75 = 91です。また、全ウィキペディア・プロジェクトを含めた最大の深さを有するウィキペディアは994のリプアーリ語版であり、最小の深さを有するウィキペディアは、8.437のチェチェン語版です。

背景

The measurement of depth was introduced after some limitations of the classic measurement of article count were realized. This insight is similar to the various suggestions to redefine the ordering of Wikipedias that appear on the international front page www.wikipedia.org. See Top Ten Wikipedias and Talk:Www.wikipedia.org portal.

Still in early February 2006 the list of Wikipedias only listed the article count. But on February 10, 2006, this changed into a table format that also listed the total edit count, number of users and admins.

The depth column first appeared on November 29, 2006. The initial definition was edits/articles, giving the English Wikipedia a value of 62. This definition changed already the next day to (Edits/Articles) × (Non-Articles/Articles), giving the English Wikipedia a value of 209. The next definition change occurred on October 9, 2007, when the Stub-ratio factor was appended. The stub ratio is (1-(Articles/Total)). The new value for the English Wikipedia was 288. The formula changed again on October 17, October 28, and finally on April 11, 2008.

The discussion of the introduction of the depth parameter is found in Talk:List of Wikipedias/Archive 4. Early on, there were discussions of whether depth implies quality. The changes in October 2007 were discussed in Talk:List of Wikipedias/Archive 5#Depth 2.0.
