Abstract
【解決手段】 抽出されたデータは特徴の形で扱うことができ、特徴は、機械学習システムと共に使用し、改良されたフィルタを構築することができる。送信元情報、ならびにメッセージの受信者がメッセージの送信者に接触および/または応答することを可能にするメッセージの本文内に埋め込まれた他の情報に関連付けられたデータを特徴として抽出することができる。特徴またはそのサブセットは、機械学習システムの特徴として使用する前に正規化および/または明瞭化することができる。特徴は、スパム検出および防止を容易にする複数の特徴リストに配置するために使用することができる。例示的な特徴には、電子メールアドレス、IPアドレス、URL、URLを指す埋込み画像、および/またはその一部分が含まれる。
