Description
1. 本システムは検索エンジンを使用し、基準ドキュメントの集合Rからキーワード(Wi1,...,Wik)全てを含む上位γ個のドキュメントを引き出す。
2. TF.IDF分析によって、本システムはこのγ個のドキュメントの集合から上位δ個のキーワードを抽出する。1実施形態では、このようなキーワードは個々のドキュメントから抽出されるのではなく、全てのドキュメントが単一の大きなドキュメントへと連結されているかのように、γ個のドキュメントを集めた集合から抽出される。
3. 動作2から取得したδ個のキーワードとシードキーワードのセットK*との積集合をW*とする。W*が空でなければ、本システムはキーワードベクトル(Wi1,...,Wik)をLに追加する。そして本システムは、リストLを出力し、終了する。
106 キーワード
108 コーパス
112 検索エンジン
Claims (3)
- プライバシーポリシーを強化するためにコンピュータが実行する方法であって、
トレーニングドキュメントのセットとプライバシーポリシーに関連付けられた1つのシードキーワードとを取得し、
前記トレーニングドキュメントから1つのキーワード候補を抽出し、
前記キーワード候補を含むクエリーをコーパスに発し、
結果ドキュメントの第1のセットを受け取り、
前記キーワード候補と前記シードキーワードとを含むクエリーをコーパスに発し、
結果ドキュメントの第2のセットを受け取り、
前記第2のセットに含まれるドキュメントの数を前記第1のセットに含まれるドキュメントの数で除した値が極めて1に近いか否かを判定し、
前記判定が肯定された場合、前記キーワード候補を前記プライバシーポリシーに関連付けることによって、前記プライバシーポリシーを強化する、
方法。 - 結果ドキュメントそれぞれに含まれる単語またはフレーズについて用語の出現頻度・ドキュメントの逆出現頻度(TF.IDF)の重みを決定することで、前記結果ドキュメントからキーワードを抽出する、ことをさらに含む、請求項1記載の方法。
- キーワード候補と各シードキーワードとの推論の強さを評価し、
キーワード候補が少なくとも1つのシードキーワードにマッチするかどうかを判定する際に評価した強さを使用する、
ことをさらに含む、請求項1記載の方法。
