今日の井原

研究室でクローラ勉強会なるものをやることになって、その中でクローラのソースコードを読むことになりました。んで、ぼくがその講師役を仰せつかりました。そこで、どのクローラのソースを読むかを決めるために、オープンソースなクローラをリストアップして、それらについて簡単に表を作りました。どこかに役立ててくれるひとがいるかもしれないんで、ここに置いておきます。

表の見方ですが……まあ、見れば分かります。たぶん。

＃クローラってのは、WWW上の文書や画像などを周期的に取得し、自動的にデータベース化するプログラムのことです。もうちょっと詳しく知りたい方はここなど御覧ください:-)

うおー。とっても参考になる。

ネット上では、クローリング技術についてあまり議論されないよね。特に、分散での処理については。
まぁ。ネット上で議論 = 個人レベル のような感じなので、分散処理（大規模）のように個人レベルを超えてるのなら仕方ないかな。

裏方すぎて注目されにくいよね。インデクサだとnamazuがかなりメジャーだけど、クローラで同じような地位に居るものって見つからない。

技術的な難しさが分かりにくい（＝理解されにくい）し、検索エンジンで使われるような大規模なものになってくると、分散処理もそうだけどハードウェアのレベルでの仕事が要求されてくるから、仰るとおり、個人レベルでは議論されないわな。どうしても。
