Description

【００９０】
この結果、情報Ｄの出現頻度が高く、多くの情報Ｄに平均的に出現するキーワードＫは、出現頻度が低いキーワードＫよりも低い重みが付けられる。また、テキスト情報が構造化されており、要約あるいは本文などの領域から構成されている場合、要約の領域に含まれるキーワードＫは、本文の領域に含まれるキーワードＫよりも高い重みが付けられる。なお、上記では、キーワード重み係数ＫＰの初期値算出方法の一例として、出現頻度と出現箇所とに基づく方法を例示したが、これに限るものではなく、種々の方法を採用できる。
【００９１】
一方、図２において、使用者が情報Ｄの重要度算出を指示した場合（Ｓ３にて YESの場合）、情報管理装置２は、Ｓ４において、重み係数Ｐに基づいて各情報Ｄの重要度Ｘｓを算出し、Ｓ５において、例えば、重要度Ｘｓの高い情報Ｄを強調して表示したり、重要度Ｘｓの高い順番に順位付けて表示するなど、情報管理装置２が算出した重要度Ｘｓを使用者が把握可能なように提示する。これにより、情報管理装置２が重要と判断する情報Ｄほど、使用者が取得しやすくなる。この結果、情報管理装置２が算出する重要度Ｘｓと使用者が感じる重要度Ｘｕとのズレが少ないほど、使用者は、少ない手間で所望の情報Ｄを取り出すことができる。なお、図２に示すＳ４が、特許請求の範囲に記載の重要度算出工程に対応し、Ｓ７が重み係数調整工程に対応する。
【００９２】
上述したように、本実施形態に係る情報管理装置２では、重み係数Ｐの一例として、情報Ｄを構成する単位であるキーワード重み係数ＫＰと、情報Ｄの蓄積単位であるファイルＦ毎に設けられるファイル重み係数ＦＰとが使用されており、情報管理装置２は、上記Ｓ４において、ある情報Ｄに含まれる各キーワードＫのキーワード重み係数ＫＰの総和と、当該情報Ｄを格納するファイルＦのファイル重み係数ＦＰとを加算して、当該情報Ｄの重要度Ｘｓを算出する。
【００９３】
ここで、上記Ｓ２で算出された重み係数Ｐの初期値は、予め定められる算出方法と、Ｓ１にて入力される情報Ｄとから決定されるので、両者が同一であれば、各情報管理装置２間で同一である。したがって、これらから算出される情報Ｄの重要度Ｘｓも、各情報管理装置２間で同一の値となる。一方、使用者が感じる情報Ｄの重要度Ｘｕは、各使用者毎に異なっているため、重み係数Ｐが初期値のままの状態では、情報管理装置２が提示する情報Ｄの重要度Ｘｓとの間にズレを生じる。
【００９４】
ところが、本実施形態に係る情報管理装置２は、例えば、情報Ｄの表示や内容変更、あるいは、検索や出力など、情報Ｄに関連する操作が行われた場合（上記Ｓ６にて YESの場合）、上記Ｓ７において、当該情報Ｄの重要度Ｘｓを算出するための重み係数Ｐを調整する。
【００９５】
これにより、例えば、キーワードの重要度を入力するなど、情報Ｄの重要度Ｘｓを管理するための操作が行われていないにも拘わらず、情報管理装置２は、使用者の感じる重要度Ｘｕへ、自らが算出する重要度Ｘｓを近づけることができる。この結果、使用者は、情報Ｄの重要度Ｘｓを管理することなく、より少ない手間で所望の情報Ｄを取り出すことができる。
【００９６】
ここで、上記Ｓ７における重み係数Ｐの調整方法としては、例えば、操作の内容や頻度、操作により情報Ｄが表示される時間など、情報Ｄに関連する操作に応じて調整する方法であれば、任意の方法を適用できるが、本実施形態では、調整方法の一例として、表示時間による重み付けについて説明する。
【００９７】
具体的には、図５に示すように、Ｓ２１において、ある情報Ｄ_A の表示を使用者が指示すると、当該指示は、操作分析部１３ｂにて識別され、情報制御部１５へ伝えられる（Ｓ２２）。情報制御部１５は、Ｓ２３において、当該通知を受け取ると、情報Ｄ_A の画面表示を行うための指令を作成して、表示制御部１２ａへ発信する。これにより、表示装置３には、情報Ｄ_A が表示される。
【００９８】
さらに、Ｓ２４において、情報制御部１５は、表示分析部１３ａへ、情報Ｄ_A の画面表示が開始されたことを通知し、Ｓ２５において、表示分析部１３ａは、情報Ｄ_A の表示時間計測を開始する。
【００９９】
一方、Ｓ２６において、使用者が情報Ｄ_A の表示終了を指示すると、当該指示は、操作分析部１３ｂにて識別され、情報制御部１５へ伝えられる（Ｓ２７）。情報制御部１５は、Ｓ２８において、情報Ｄ_A の画面表示を終了するための指令を作成して、表示制御部１２ａへ発信する。これにより、情報Ｄ_A の画面表示は終了する。
【０１００】
さらに、本実施形態に係る情報制御部１５は、Ｓ２９において、情報Ｄ_A の画面表示が終了されたことを表示分析部１３ａへ通知する。一方、Ｓ３０において、表示分析部１３ａは、当該通知に基づいて、情報Ｄ_A の表示時間計測を終了する。
【０１０１】
ここで、履歴記憶部１１ｃには、過去に情報Ｄが表示された時間の総和を示す総表示時間Ｔが、各情報Ｄに対応して格納されている。表示分析部１３ａは、Ｓ３１において、情報Ｄ_A の総表示時間Ｔ_A に、今回の表示時間を加算する。この加算結果は、新たな総表示時間Ｔ_A として、履歴記憶部１１ｃに格納される。なお、例えば、初めて表示された場合など、総表示時間Ｔ_A が履歴記憶部１１ｃに格納されていない場合は、表示分析部１３ａは、今回の表示時間を新たな総表示時間Ｔ_A として格納する。
【０１０２】
さらに、重み係数処理部１４ａは、Ｓ３２において、履歴記憶部１１ｃに格納された情報Ｄ_A の総表示時間Ｔ_A を参照して、総表示時間Ｔ_A が長いほど、当該情報Ｄ_A の重要度Ｘｓ_A が大きくなるように、当該情報Ｄ_A の重み係数Ｐ_A を調整する。
【０１０３】
例えば、以下の表２に示すように、情報Ｄ_B の総表示時間Ｔ_B が、情報Ｄ_A の総表示時間Ｔ_A の２倍の場合、重み係数処理部１４ａは、情報Ｄ_A の重み係数Ｐ_A の２倍に、情報Ｄ_B の重み係数Ｐ_B を増加させる。なお、表２では、比較のために、総表示時間Ｔのみが異なり、例えば、調整前の重み係数Ｐなど、他の条件が同一な情報Ｄ_A ・Ｄ_B ・Ｄ_C を例示しており、重み係数比は、重み係数Ｐ_A の値を１とした場合の比率である。
【０１０４】
【表２】

【０１０５】
本実施形態では、重み係数Ｐとして、ファイル重み係数ＦＰとキーワード重み係数ＫＰとが使用されているので、情報Ｄ_B が格納されるファイルＦ_B のファイル重み係数ＦＰ_B は、情報Ｄ_A が格納されるファイルＦ_A のファイル重み係数ＦＰ_A の２倍だけ増加し、情報Ｄ_B に含まれるキーワードＫ_B1のキーワード重み係数ＫＰ_B1は、情報Ａに含まれるキーワードＫ_A1のキーワード重み係数ＫＰ_A1の２倍だけ増加する。同様に、情報Ｄ_C の重み係数Ｐ_C は、情報Ｄ_A の重み係数Ｐ_A の１．５倍に増加する。
【０１０６】
上記Ｓ２１〜Ｓ３２の処理は、他の情報Ｄでも実施されるので、総表示時間Ｔが長い情報Ｄほど、重要度Ｘｓが相対的に増大し、総表示時間Ｔが短い情報Ｄほど、重要度Ｘｓが相対的に低下する。
【０１０７】
一般に、情報管理装置２の使用者は、主として、表示装置３の表示画面に表示された情報Ｄを見ながら、操作入力装置４を操作している。したがって、使用者が、ある情報Ｄに注意を払っているほど、当該情報Ｄの表示時間が長くなることが多い。ここで、情報管理装置２は、情報Ｄの総表示時間Ｔが長いほど、使用者が当該情報Ｄを重要視していると推測して重み係数Ｐを調整する。この結果、図２に示すＳ２の時点では、使用者の感じる情報Ｄの重要度Ｘｕと、情報管理装置２が算出する重要度Ｘｓとの間にズレが発生したとしても、上記Ｓ２１〜Ｓ３２（図２に示すＳ３〜Ｓ７）の処理を繰り返す毎に、ズレが縮小される。この結果、情報管理装置２は、各使用者に適合した重要度Ｘｓを提示できる。
【０１０８】
なお、この例では、ファイル重み係数ＦＰとキーワード重み係数ＫＰとの双方を調整しているが、一方のみを調整してもよい。ただし、ファイル重み係数ＦＰのみを調整する場合は、使用者が表示させた情報Ｄ_A の重要度Ｘｓ_A のみが調整される。したがって、他の情報Ｄ_B の内容が情報Ｄ_A に類似していたとしても、当該情報Ｄ_B の重要度Ｘｓ_B は変化せず、当該情報Ｄ_B の検索に手間や時間がかかる虞れがある。
【０１０９】
一方、キーワード重み係数ＫＰを調整する場合は、使用者が１つの情報Ｄに注目して操作するだけで、類似の内容を持つ情報Ｄ_B の重要度Ｘｓ_B も上昇する。この結果、使用者が当該情報Ｄ_B を発見しやすくなる。ところが、キーワード重み係数ＫＰのみを調整する場合は、両情報Ｄ_A ・Ｄ_B の重要度Ｘｓ_A ・Ｘｓ_B が同様に変化するため、使用者は、直接指示した情報Ｄ_A を他の情報Ｄ_B から区別しにくくなる。この結果、直接指示した情報Ｄ_A を検索したい場合には、手間や時間がかかる虞れがある。
【０１１０】
これに対して、本実施形態では、重み係数Ｐとして２つの重み係数ＦＰ・ＫＰを併用し、双方を調整している。この結果、直接指示した情報Ｄ_A の検索を妨げることなく、類似の情報Ｄ_B を発見しやすくできる。
【０１１１】
また、上記の例では、重み係数Ｐの増加率と、総表示時間Ｔとが比例するように重み係数Ｐを調整したが、これに限るものではない。増加率に代えて、増加幅で調整してもよいし、他の数式を用いて調整してもよい。総表示時間Ｔのみが異なる場合で比較した場合、総表示時間Ｔが長くなるに従って、情報Ｄの重要度Ｘｓが大きくなるような調整方法であれば、本実施形態と同様の効果が得られる。
【０１１２】
ただし、情報管理装置２がより使用者の感覚に近い重要度Ｘｓを算出するためには、例えば、図６に示すように、総表示時間Ｔに対してＳ字状に変化するように重み係数Ｐを調整する方が望ましい。この場合は、総表示時間Ｔが少ないうちは、重み係数Ｐが徐々に増加し、総表示時間Ｔが増大すると、重み係数Ｐの傾きが急峻になる。さらに、重み係数Ｐが所定の上限値Ｐ_LIM に近づくと、重み係数Ｐは、緩やかに上昇する。これにより、総表示時間Ｔに起因する重要度Ｘｓの変動を使用者の感覚に近づけることができる。
【０１１３】
また、情報管理装置２が動作を開始してからの時間が長くなると、各情報Ｄの総表示時間Ｔが長くなり、各情報Ｄの重要度Ｘｓが近づく虞れがある。したがって、ファイルＦあるいはキーワードＫに関連しない表示が続く場合は、図７に示すように、当該ファイルＦあるいはキーワードＫの重み係数Ｐ（ＫＰ・ＦＰ）を徐々に減少させる方がよい。これにより、時間が経過しても、各情報Ｄの重要度Ｘｓを広い範囲に分散させることができ、使用者は、所望の情報Ｄを発見しやすくなる。
【０１１４】
なお、上記の例では、履歴記憶部１１ｃへ、情報Ｄの総表示時間Ｔ自体を格納しているが、これに限るものではない。例えば、各情報Ｄの表示開始を指示した時刻と、各情報Ｄの表示停止を指示した時刻とを格納して、各情報Ｄの総表示時間を算出してもよい。また、表示装置３がマルチウィンドウ表示でき、複数の情報Ｄをオーバーラップして表示可能な場合は、表示時間を測定する際、表示の重なり順位に重みを付けてもよい。いずれの場合であっても、情報Ｄの表示時間に応じて、当該情報Ｄの重み係数Ｐを調整できれば、本実施形態と同様の効果が得られる。
【０１１５】
〔第２の実施形態〕
ところで、情報Ｄの総表示時間Ｔのみに基づいて、重み係数Ｐを調整する場合、例えば、画面の背景的に表示されている情報Ｄの重要度Ｘｓも増加してしまう。また、例えば、使用者が情報管理装置２から離れている場合など、使用者が当該情報Ｄを注視していない場合であっても、重要度Ｘｓが増大する虞れがある。
【０１１６】
本実施形態では、重み係数Ｐを調整する際の別の尺度として、図６〜図９を参照しながら、情報Ｄの操作回数について説明する。なお、情報Ｄへの操作には、種々の操作が存在するが、以下では、情報Ｄの表示開始指示と表示停止指示とを例にして説明する。この場合、例えば、使用者の指示や画面表示に関する処理は、図５の処理と同様なので、同じ処理には同じ参照符号を付して説明を省略する。また、本実施形態および以下の実施形態では、情報管理装置２の構成は、第１の実施形態と同様で、各部の動作のみが異なっているため、図１を参照して説明する。
【０１１７】
すなわち、図８に示すＳ２１〜Ｓ２４において、情報管理装置２は、使用者の指示に応じて、表示装置３へ情報Ｄ_A を表示し、情報制御部１５は、表示分析部１３ａへ表示開始を通知する。一方、本実施形態に係る表示分析部１３ａは、Ｓ４１において、履歴記憶部１１ｃに格納されている情報Ｄ_A の操作回数ｍ_A を１増加させる。
【０１１８】
また、使用者が表示終了を指示する場合、Ｓ２６〜Ｓ２９において、情報管理装置２は、表示装置３への情報Ｄ_A の表示を停止し、情報制御部１５は、表示分析部１３ａへ表示停止を通知する。この場合、上記Ｓ４１と同様に、Ｓ４２では、情報Ｄ_A の操作回数ｍ_A を１増加させる。これにより、履歴記憶部１１ｃには、各情報Ｄの操作回数ｍが格納される。
【０１１９】
さらに、重み係数処理部１４ａは、Ｓ４３において、履歴記憶部１１ｃに格納された情報Ｄ_A の操作回数ｍ_A を参照して、操作回数ｍ_A が多いほど、当該情報Ｄ_A の重要度Ｘｓ_A が大きくなるように、当該情報Ｄ_A の重み係数Ｐ_A を調整する。
【０１２０】
例えば、以下の表３に示すように、情報Ｄ_B の操作回数ｍ_B が、情報Ｄ_A の操作回数ｍ_A の２倍の場合、重み係数処理部１４ａは、図５に示すＳ３２と同様に、情報Ｄ_A の重み係数Ｐ_A の２倍だけ、情報Ｄ_B の重み係数Ｐ_B を増加させる。なお、以下の表３では、比較のために、操作回数ｍ_A のみが異なり、他の条件が同一な情報Ｄ_A ・Ｄ_B ・Ｄ_C を例示している。また、重み係数比は、重み係数Ｐ_A を１とした場合の比率である。
【０１２１】
【表３】

【０１２２】
上記Ｓ２１〜Ｓ４３の処理は、他の情報Ｄでも実施されるので、操作回数ｍが多い情報Ｄほど、重要度Ｘｓが相対的に増大し、操作回数ｍが少ない情報Ｄほど、重要度Ｘｓが相対的に低下する。
【０１２３】
ここで、画面に表示されている情報Ｄであっても、使用者が何も操作しない情報Ｄは、頻繁に操作する情報Ｄに比べて、重要度が低いことが多い。例えば、画面の背景として表示され、操作されない情報Ｄは、多くの場合、画面の最も前のウィンドウに表示され、頻繁に操作される情報Ｄに比べて重要度が低い。また、情報Ｄが長時間表示されていても、使用者が情報管理装置２から離れている場合もある。
【０１２４】
本実施形態に係る情報管理装置２は、情報Ｄの操作回数ｍが多いほど、使用者が当該情報Ｄを重要視していると推測して、重み係数Ｐを調整する。したがって、使用者が情報管理装置２から離れている期間の長さに拘わらず、重み係数Ｐを調整できる。なお、操作回数ｍに応じて重み係数Ｐが調整されるので、第１の実施形態のように、総表示時間Ｔに基づく調整と併用した場合であっても、使用者が情報管理装置２から離れている期間に起因する重み係数Ｐの変動を相対的に抑制できる。これらの結果、使用者の感じる重要度Ｘｕへ、情報管理装置２が算出する重要度Ｘｓを近づけることができる。
【０１２５】
なお、上記では、表示開始操作および停止操作を数える場合を例にして説明したが、これに限るものではない。使用者にとって当該情報Ｄが重要であると推測された種類の操作を数えれば、同様の効果が得られる。一例として、例えば、再表示や拡大表示など、表示状態を変更する種類の操作、例えば、情報Ｄの内容の修正や追加、部分複写あるいは部分削除など、情報Ｄの内容を変更する種類の操作と、例えば、外部記録媒体への複写や印刷あるいは送信など、情報管理装置２外へ出力する種類の操作となどが挙げられる。さらに、操作の対象としては、表示している情報Ｄ、情報Ｄの一部分、あるいは、情報Ｄを格納するファイルＦなどが挙げられる。例えば、ファイルＦの操作回数を数える場合には、使用者がファイルＦ_A を使用する度に、当該ファイルＦの操作回数ｍ_A は、１ずつ加算され、各ファイルＦの操作回数ｍに応じて、ファイルＦに格納された情報Ｄの重み係数Ｐが調整される。いずれの場合であっても、使用者が当該情報Ｄを重要視している種類の操作は、予め推測できるので、情報管理装置２は、これらの種類の操作が行われた際、操作回数を数えて、操作に関連する情報Ｄの重み係数Ｐを調整できる。
【０１２６】
なお、第１の実施形態と同様に、操作回数ｍに応じた重み係数Ｐの調整方法は、増加幅や増加率、あるいは、比例関係や任意の関数など種々の方法を採用できる。いずれの場合であっても、操作回数が多いほど、ある情報Ｄの重要度Ｘｓが上昇するような調整方法であれば、本実施形態と同様の効果が得られる。
【０１２７】
ただし、第１の実施形態と同様に、図６に示すように、操作回数ｍに対してＳ字状に変化するように重み係数Ｐを調整した方が、操作回数ｍに起因する重要度Ｘｓの変動を使用者の感覚に近づけることができる。また、図７に示すように、ファイルＦやキーワードＫに関連しない操作が続く場合、当該ファイルＦあるいはキーワードＫの重み係数Ｐ（ＫＰ・ＦＰ）を徐々に減少させる方が、所望の情報Ｄを発見しやすくなる。
【０１２８】
一方、情報Ｄの削除など、使用者にとって、その情報Ｄが不要と推測される種類の操作が行われた場合、例えば、図９に示すように、情報管理装置２は、操作回数ｍの増加に伴って、当該情報Ｄの重み係数Ｐを低下させる方がよい。当該種類の操作も予め推測できるので、情報管理装置２は、これらの種類の操作が行われた際、何ら支障なく、操作に関連する情報Ｄの重み係数Ｐを調整できる。
【０１２９】
〔第３の実施形態〕
ところで、第２の実施形態では、操作回数の数え方の一例として、各操作を同等に数える場合について説明した。ところが、実際の操作には、例えば、バックスクロール操作など、使用者が情報Ｄを重要視しているときに頻出する特定種類の操作が存在する。したがって、当該特定種類の操作が行われた場合と、残余の操作が行われた場合とで、同じように重み係数Ｐを調整すると、情報管理装置２が算出する重要度Ｘｓと使用者が感じる重要度Ｘｕとの間にズレが発生する虞れがある。
【０１３０】
これに対して、本実施形態では、例えば、上記特定種類の操作を数えるなど、情報Ｄの操作内容に応じて重み係数Ｐを調整する場合について、図１０〜図１３を参照しながら説明する。なお、以下では、特定操作の一例として、バックスクロール操作など、情報Ｄの中の同じ部分を再表示させる操作について説明する。
【０１３１】
すなわち、図１０に示すＳ５１において、情報Ｄ_A 中の、ある部分Ａ_A1を表示するように、使用者が指示した場合、情報制御部１５は、Ｓ５２において、使用者の指示に基づいて、当該部分Ａ_A1を表示するための指令を作成する。表示制御部１２ａは、当該指令に応じて、表示装置３の画面上に、例えば、図１１に示すように、情報Ｄ_A のうちの指示された部分Ａ_A1を表示する。
【０１３２】
さらに、情報制御部１５は、Ｓ５３において、当該部分Ａ_A1の画面表示が開始されたことを表示分析部１３ａへ通知する。また、表示分析部１３ａは、Ｓ５４において、当該部分Ａ_A1を示す部分情報Ｂ_A1が、履歴記憶部１１ｃに格納されているか否かを照合して、当該部分Ａ_A1が過去に表示されたか否かを判定する。例えば、図１２に示す例では、履歴記憶部１１ｃに格納されている部分情報Ｂ_A2は、部分Ａ_A2を示しており、現在、表示している部分Ａ_A1と異なっている。このように、上記部分Ａ_A1を示す部分情報Ｂ_A1が、履歴記憶部１１ｃに格納されていない場合、表示分析部１３ａは、当該部分Ａ_A1が過去に表示されていないと判定す。この場合、表示分析部１３ａは、部分情報Ｂ_A1を作成して、履歴記憶部１１ｃに格納する（Ｓ５５）。
【０１３３】
一方、部分Ａ_A1が過去に表示されている場合（上記Ｓ５４にて、 YESの場合）、例えば、図１３に示すように、現在、表示している部分Ａ_A1を示す部分情報Ｂ_A1は、既に、履歴記憶部１１ｃに格納されている。この場合、表示分析部１３ａは、使用者が情報Ｄ_A に対して再表示操作を行ったと判断し、情報Ｄ_A の再表示操作回数ｄ_A を１増加させる。当該再表示操作回数ｄ_A は、履歴記憶部１１ｃに格納される（Ｓ５６）。
【０１３４】
さらに、重み係数処理部１４ａは、Ｓ５７において、情報Ｄ_A の再表示操作回数ｄ_A を参照して、再表示操作回数ｄ_A が多いほど、当該情報Ｄ_A の重要度Ｘｓ_A が大きくなるように、当該情報Ｄ_A の重み係数Ｐ_A を調整する。
【０１３５】
例えば、比較のために、再表示操作回数ｄ_A のみが異なり、他の条件が同一な情報Ｄ_A ・Ｄ_B を例にして説明すると、情報Ｄ_B の再表示操作回数ｄ_B が、情報Ｄ_A の再表示操作回数ｄ_A の２倍の場合、重み係数処理部１４ａは、上述の表３と同様に、情報Ｄ_A の重み係数Ｐ_A の２倍だけ、情報Ｄ_B の重み係数Ｐ_B を増加させる。
【０１３６】
上記Ｓ５１〜Ｓ５７の処理は、他の情報Ｄでも実施されるので、再表示操作回数ｄが多い情報Ｄほど、重要度Ｘｓが相対的に増大し、再表示操作回数ｄが少ない情報Ｄほど、重要度Ｘｓが相対的に低下する。これにより、情報管理装置２は、使用者の感覚に近い重要度Ｘｓを算出できる。
【０１３７】
なお、上記では、再表示操作回数ｄを数えたが、これに限るものではない。使用者が情報Ｄを重要視している場合に頻出する操作であれば、予め定められた特定種類の操作として他の操作を数えた場合でも同様の効果が得られる。
【０１３８】
さらに、特定種類の操作として、複数の種類の操作を数え、各操作毎に、重み係数Ｐを変化させてもよい。例えば、上記特定種類の操作として、情報Ｄを表示する操作と、情報Ｄの内容を修正する操作と、フロッピーディスクなど、可搬性の記録媒体へ情報Ｄを複写する操作と、電子メールなど、当該情報Ｄを通信する操作と、情報Ｄを印刷する操作とをそれぞれ数える。さらに、表示操作時の重み係数Ｐの増加割合を１として、修正操作時の重み係数Ｐの増加割合を１．５、複写操作時の増加割合を２、通信操作時の増加割合を２．５、印刷操作時の増加割合を３などのように、操作毎の重み係数Ｐの増加割合を変化させる。
【０１３９】
一般に、情報Ｄの印刷、通信、複写など、情報管理装置２の外部へ情報Ｄを出力する操作が行われた場合、使用者は、当該情報Ｄを多くの人々に活用させようとしていることが多く、情報管理装置２内部で情報Ｄを処理している場合に比べて、使用者が情報Ｄを重要視していると推測できる。また、使用者は、必要がない限り、情報Ｄの内容を修正しないことが多いので、使用者は、単に表示されている情報Ｄに比べて、内容を修正した情報Ｄの方を重要視していると推測される。したがって、上述のように、表示操作、修正操作、複写操作、通信操作、印刷操作の順番で重みを付けて、情報Ｄの重み係数Ｐを調整すれば、情報管理装置２は、使用者の感覚にさらに近い重要度Ｘｓを算出できる。
【０１４０】
なお、上記では、それぞれの操作回数を別に数える場合を例にして説明したが、これに限るものではない。例えば、印刷操作を修正操作の３回分と数えるなど、計数の段階で重みを付けてもよい。操作回数を別にするか否かに拘わらず、上述の特定種類の操作毎に、重要度Ｘｓの変動幅を変更できれば、本実施形態と同様の効果が得られる。
【０１４１】
〔第４の実施形態〕
ところで、上記第１ないし第３の実施形態では、操作対象が情報Ｄ全体であるか否かに拘わらず、情報Ｄ毎に、表示時間や操作回数を数え、情報Ｄの重要度算出に使用される重み係数Ｐが調整される場合について説明した。これに対して、本実施形態では、操作対象が情報Ｄの一部分の場合、当該部分に関連する重み係数Ｐを調整する場合について、図１４および図１５に基づき説明する。なお、情報Ｄの一部分を操作対象とする操作は、種々の操作が挙げられるが、以下では、部分表示を例にして説明する。
【０１４２】
すなわち、図１４に示すＳ６１において、表示分析部１３ａは、情報Ｄが画面表示される毎に、例えば、情報制御部１５からの通知などに基づいて、情報Ｄのうち、どの部分Ａが表示されているかを判定し、重み係数処理部１４ａへ通知する。一方、重み係数処理部１４ａは、Ｓ６２において、情報分析部１３ｃに依頼して、図１５に示すように、当該部分Ａに含まれているキーワードを抽出する。さらに、Ｓ６３において、重み係数処理部１４ａは、例えば、各キーワードＫ毎に操作回数を数え、操作回数に応じて、キーワード重み係数ＫＰを調整するなどして、当該キーワードＫが部分Ａに含まれていない場合よりも重要度Ｘｓが大きくなるように、当該キーワードＫのキーワード重み係数ＫＰを調整する。
【０１４３】
なお、キーワード重み係数ＫＰの調整方法は、第２あるいは第３の実施形態と同様に、各種操作を区別せずに調整してもよいし、操作の種類毎に重みを付けてもよい。また、操作対象の削除など、使用者が操作対象が不要と推測される操作の場合は、キーワードＫの重要度Ｘｓが減少するように、キーワード重み係数ＫＰを調整する。
【０１４４】
いずれの場合であっても、情報Ｄの一部分が操作された場合、当該情報Ｄの中の各キーワードＫが操作対象に含まれるか否かによって、キーワードＫのキーワード重み係数ＫＰを個別に調整できる。したがって、情報管理装置２は、より使用者の感覚に近い重要度Ｘｓを算出できる。
【０１４５】
〔第５の実施形態〕
第４の実施形態では、情報Ｄの操作対象に含まれているか否かによって、キーワード重み係数ＫＰを調整する場合について説明したが、キーワードＫは、情報Ｄのみに含まれるものではなく、例えば、検索文字列など、使用者が入力する文字列にも含まれる。本実施形態では、図１６を参照しながら、入力文字列に応じたキーワード重み係数ＫＰの調整について説明する。
【０１４６】
すなわち、Ｓ７１において、例えば、検索や情報Ｄの修正などのために、使用者が文字列を入力すると、情報管理装置２の入力制御部１２ｂは、入力された文字列を情報分析部１３ｃへ通知する。さらに、情報分析部１３ｃは、Ｓ７２において、入力文字列中に含まれているキーワードＫを抽出する。
【０１４７】
一方、Ｓ７３において、情報制御部１５は、例えば、入力時点における情報管理装置２の状況（モード）を調査するなどして、当該入力文字列の用途を識別し、重み係数処理部１４ａへ通知する。さらに、重み係数処理部１４ａは、状況に応じて、各キーワードＫのキーワード重み係数ＫＰを調整する（Ｓ７４）。
【０１４８】
例えば、情報管理装置２がファイルＦを新規作成する状況であった場合、重み係数処理部１４ａは、キーワード重み係数ＫＰを増加させる割合を１に設定する。これとは逆に、情報管理装置２が情報Ｄを更新する状況にあった場合、重み係数処理部１４ａは、キーワード重み係数ＫＰを増加させる割合を１．５に設定する。また、情報Ｄを検索する状況の場合、キーワード重み係数ＫＰは、２の割合で増加する。
【０１４９】
上記構成によれば、使用者が入力した文字列に含まれるキーワードＫは、当該キーワードＫが入力文字列に含まれない場合よりも、キーワード重み係数ＫＰが大きくなる。さらに、入力文字列に含まれる場合であっても、キーワードＫのキーワード重み係数ＫＰは、新規作成、更新、検索の順番で大きくなる。
【０１５０】
一般に、使用者は、文字列を入力する際、使用者自身が重要視する文字列を入力している。したがって、使用者の入力文字列中に含まれるキーワードＫの重要度を大きくすることで、情報管理装置２は、使用者の感覚に近い重要度Ｘｓを算出できる。
【０１５１】
さらに、文字列の長さは、新規作成、更新、検索の順番で短くなることが多い。特に、検索時には、使用者が重要視しているキーワードＫのみが入力されることが多く、新規作成時には、重要視しているキーワードＫだけではなく、他のキーワードＫも入力される。したがって、上述のように、文字列の用途に応じて、キーワード重み係数ＫＰを調整することで、情報管理装置２は、さらに、使用者の感覚に近い重要度Ｘｓを算出できる。
【０１５２】
〔第６の実施形態〕
ところで、上記第１ないし第５の実施形態では、例えば、総表示時間Ｔや総操作回数ｍ（ｄ）など、情報Ｄ（ファイルＦ）が生成されてからの操作状況全てに応じて、重み係数Ｐを調整する方法（第１の方法）について説明した。この方法によれば、操作回数ｍに応じる場合、操作回数ｍが多い情報Ｄほど、重要度Ｘｓが増加するので、情報管理装置２は、例えば、図１７に示すように、操作回数ｍが異なる情報Ｄについて、互いに異なる重要度Ｘｓを提示できる。
【０１５３】
ところが、この第１の方法では、例えば、図１８に示すように、１年前に作成されて、その頃にｎ回操作されたファイルＦ_A に格納された情報Ｄ_A の重要度Ｘｓ_A は、最近作成され、ｎ回操作されたファイルＦ_B に格納された情報Ｄ_B の重要度Ｘｓ_B と同一になってしまう。
【０１５４】
ここで、一般に最近頻繁に操作された情報Ｄ_B は、かつて頻繁に操作された情報Ｄ_A よりも、現時点での重要度Ｘｓが高いことが多い。したがって、第１の方法で重み係数Ｐを調整すると、上記両重要度Ｘｓ_A ・Ｘｓ_B の値が近くなり、使用者が情報Ｄ_B を発見しにくくなる虞れがある。
【０１５５】
これに対して、本実施形態に係る重み係数処理部１４ａは、第２の方法として、ファイルＦが作成されてから現在に至るまでの経過時間Ｒで、総操作回数ｍを割った値（ｍ／Ｒ）に応じて、重み係数Ｐを変更する。なお、経過時間Ｒは、情報Ｄの属性として格納される作成日時などから算出できる。
【０１５６】
本実施形態では、重み係数処理部１４ａは、操作回数ｍに代えて、ｍ／Ｒに応じて、重み係数Ｐを調整する。したがって、経過時間Ｒが長い情報Ｄほど、重み係数Ｐの維持に必要な操作回数ｍが大きくなり、重要度Ｘｓが相対的に低下する。この結果、情報管理装置２は、現時点での使用者の感覚にさらに近い重要度Ｘｓを算出できる。
【０１５７】
〔第７の実施形態〕
ところで、第１ないし第６の実施形態では、履歴記憶部１１ｃに格納された総表示時間Ｔや操作回数ｍなどが、操作時に更新される場合について説明したが、総表示時間Ｔや操作回数を求める方法は、これに限るものではない。
【０１５８】
本実施形態では、操作時には、操作時刻などを含む履歴情報Ｈが履歴記憶部１１ｃに格納され、当該履歴情報Ｈに基づいて、重要度Ｘｓを算出する場合について説明する。なお、以下では、説明の便宜上、第２の実施形態において、履歴情報Ｈを格納する場合を例にして説明する。
【０１５９】
すなわち、図１９に示すように、Ｓ８１において、使用者が情報Ｄを操作すると、情報制御部１５は、Ｓ８２において、操作の履歴情報Ｈを格納する。当該履歴情報Ｈには、操作の時期と、重要度Ｘｓを後で算出する際、必要な情報とが含まれている。例えば、情報Ｄへ操作回数に基づいて重要度Ｘｓを算出する場合は、履歴情報Ｈには、操作した日時と、操作対象となる情報Ｄとが含まれる。
【０１６０】
さらに、重要度Ｘｓを算出する際、重み係数処理部１４ａは、Ｓ８３において、各情報Ｄの履歴情報Ｈに基づいて、それぞれの重み係数Ｐを調整し、重要度Ｘｓを算出する。
【０１６１】
ここで、本実施形態では、重み係数処理部１４ａは、履歴記憶部１１ｃに格納された履歴情報Ｈから、各情報Ｄ_A に関連する履歴情報Ｈをそれぞれ抽出すれば、各情報Ｄの操作回数ｍを算出できる。したがって、重み係数処理部１４ａは、上記第１の方法および第２の方法と同様に、操作回数ｍ、あるいは、操作回数ｍを経過時間Ｒで割った値に応じて、各情報Ｄの重み係数Ｐを調整できる。
【０１６２】
さらに、本実施形態では、履歴情報Ｈが格納されているため、上記第１の方法および第２の方法に加えて、操作時期に応じて重みを付ける第３の方法を選択できる。
【０１６３】
例えば、最近１か月に１回使用した場合に、重み係数Ｐを増加させる割合を１とした場合、過去１か月前から２か月前までの期間に１回使用した場合を０．９、２か月前から３か月前までの期間を０．８のように、操作する時点が、現時点から離れるに従って重みが小さくなるように重みを付けて、重み係数Ｐを調整する。これにより、図２０に示すように、経過時間Ｒと操作回数ｍとが同一であっても、より最近に操作された情報Ｄの重要度Ｘｓを相対的に増加できる。この結果、情報管理装置２は、使用者の感覚にさらに適合した重要度Ｘｓを算出できる。
【０１６４】
ここで、上記では、現時点との差に応じて重みを付ける場合について説明したが、これに限るものではない。任意の時点との差に応じて、重みを付ければ、当該時点における使用者の感覚に適合した重要度Ｘｓを算出できる。一般に、使用者が感じる重要度Ｘｕは、常に一貫している訳ではなく、時間の経過と共に変化することが多い。したがって、使用者は、ある時点において重要と考えていた情報Ｄに基づいて、情報Ｄを検索することがある。この場合には、情報管理装置２は、ある時点での使用者の感覚に近い重要度Ｘｓを算出することが求められる。第３の方法では、履歴情報Ｈを算出することで、任意の時点での重要度Ｘｓを算出できる。さらに、履歴記憶部１１ｃが履歴情報Ｈを格納しているので、使用者の要求に応じて、第１の方法〜第３の方法のうちの任意の方法を選択できる。したがって、使用者が所望の情報Ｄを発見する際の手間を大幅に削減できる。
【０１６５】
なお、上記では、履歴情報Ｈとして、第２の実施形態での重要度算出に必要な情報が記憶されている場合を例にして説明したが、第１ないし第５の実施形態での重要度算出に必要な情報を記憶すれば、いずれに適用しても、同様の効果が得られる。
【０１６６】
特に、第３の実施形態に適用した場合、重要度算出時点で、特定種類の操作を特定できると共に、各種操作間の重み付けを変更できる。例えば、印刷操作の重みを重くすれば、通信操作された情報Ｄの重要度Ｘｓを大きくできる。したがって、情報管理装置２が重要度Ｘｓを算出する際の方法を、より柔軟に変化させることができ、使用者が所望の情報Ｄを発見する際の手間を大幅に削減できる。
【０１６７】
ところで、履歴情報Ｈを格納する場合は、総表示時間Ｔや操作回数ｍ（ｄ）を格納する場合に比べて、多くの記憶容量を必要とする。ところが、履歴情報Ｈの格納に必要な記憶容量は、情報Ｄの格納に必要な記憶容量よりも極めて小さいことが多いので、情報管理装置２全体の記憶容量は、余り増加しない。
【０１６８】
なお、上記各第１ないし第７の実施形態で説明した重み係数Ｐの調整方法は、任意の組み合わせで併用できる。この場合は、各種の操作に応じて、重み係数Ｐを調整できるので、情報管理装置２は、さらに使用者の感覚に近い重要度Ｘｓを算出できる。特に、例えば、再表示の有無、外部出力の有無など、互いに異なる操作に基づいて、重み係数Ｐを調整すれば、広く一般の操作に応じて、重み係数Ｐを調整できるので、情報管理装置２は、より的確に重要度Ｘｓを算出できる。
【０１６９】
また、上記各実施形態では、重み係数Ｐが増大すれば、情報Ｄの重要度Ｘｓが増大する場合について説明したが、これに限るものではない。例えば、重み係数Ｐが増大した場合、情報Ｄの重要度Ｘｓが減少する場合など、他の方法で重要度Ｘｓを算出する場合であっても、上記各実施形態と情報Ｄの重要度Ｘｓが同様に変化するように、重み係数Ｐを調整できれば、同様の効果が得られる。
【０１７０】
さらに、上記各実施形態では、情報Ｄに関連する操作が行われた場合、当該情報Ｄの重要度算出に使用される重み係数Ｐを調整する場合について説明したが、これに限らず、例えば、情報Ｄの重要度算出に使用されない重み係数Ｐを調整してもよい。重要度算出に使用される重み係数Ｐの大きさと、残余の重み係数Ｐの大きさとを、相対的に変更できれば、同様の効果が得られる。
【０１７１】
また、上記各実施形態に係る記録媒体は、各情報に応じて作成される重み係数のうち、 情報に関連する重み係数に基づいて、当該情報の重要度を算出する重要度算出工程と、情報に関連する操作に応じて、上記重要度算出工程で使用される重み係数を調整する重み係数調整工程とを実行するプログラムが記録されていることを特徴としている。

BACKGROUND OF THE INVENTION
The present invention relates to an information management apparatus that manages various types of information while changing the importance of information according to a user, and a recording medium on which the program is recorded.
[0002]
[Prior art]
Conventionally, for example, managing various information using a computer or the like has been widely performed. The amount of information managed by these information management devices tends to increase more and more due to, for example, the widespread use of large-capacity recording media such as CD-ROMs and the expansion of information databases due to the development of information networks. The amount of information that can be manually organized and managed is being exceeded. Therefore, in recent years, an automatic organization / management technique using the information management apparatus itself has been proposed.
[0003]
For example, the information management apparatus described in Japanese Patent Application Laid-Open No. 5-20362 analyzes the contents of text stored in units of documents and automatically extracts the key words (keywords) that are the keys of each information, Each document is organized by automatically associating each document based on the importance of each keyword. In this way, the information management apparatus supports, so that it is possible to reduce the trouble for the user to extract necessary information from a large amount of information.
[0004]
[Problems to be solved by the invention]
However, since the importance level felt by the user is often different for each user, the conventional information management apparatus has a problem that it is difficult to provide sufficient support adapted to the intention of each user.
[0005]
Specifically, in the information management apparatus configured as described above, since each keyword is managed by mechanically extracting a keyword from the content of the information, each information is classified from a common point of view by each user. On the other hand, the degree of importance felt by the user is generally different for each user due to various factors such as the job type and interest of the user. Therefore, there is a difference between the importance managed by the information management device and the importance felt by the user of the information management device, and the information management device configured as described above stores the information with the importance according to each user. It is difficult to manage. As a result, in the information management apparatus, it is difficult to support the user in conformity with the user, and it is difficult to say that the effort for the user to extract necessary information is sufficiently reduced.
[0006]
Here, as a method of overcoming the above problem, there is a method of allowing each user to change the importance of the keyword. However, when recognizing the importance of a keyword, the user usually only recognizes the magnitude or ratio of the importance with other keywords, and sets the importance of the keyword to a desired value. Is difficult even for the user. Furthermore, since the amount of keywords increases as the amount of information increases, in the above configuration, the user manages a large number of keywords. Therefore, the user is required to manage keywords newly while being freed from information importance management. As a result, in order to extract necessary information, it still requires a lot of time and is a burden on the user. Furthermore, as the amount of information increases, there is a possibility that keywords cannot be managed completely.
[0007]
On the other hand, as another method for reflecting the importance felt by the user to the information management apparatus, in Japanese Patent Laid-Open No. 6-309291, the display layout based on the importance calculated by the information management apparatus is displayed by the user. A configuration is disclosed that learns and controls the weighting factor at the time of display layout calculation so as to match the layout. However, this configuration cannot be applied to general operations because the user needs to specify a target value by learning control of the information management apparatus.
[0008]
Furthermore, the weighting factor described in the publication is a parameter for combining basic importance functions in importance calculation such as structural importance functions and semantic importance functions. Therefore, the correction of the weighting factor is reflected as the correction of the policy when determining the display layout, and it is difficult to change the importance of each piece of information itself.
[0009]
Further, since it is indispensable to display in a display layout corresponding to the importance, the type of display device and the use of the information management device are limited. As a result, the application range of the information management apparatus is limited.
[0010]
The present invention has been made in view of the above problems, and an object of the present invention is to provide an information management apparatus that can be applied to a wide range and can manage information while changing the importance according to the user. It is to provide.
[0011]
[Means for Solving the Problems]
The present inventionIn order to solve the above problem, the information management apparatus according toWeighting factor storage means for storing weighting factors that are created according to each information and used to calculate the importance of related information, and the importance that calculates the importance of the information based on the weighting factors related to the information A calculating means and a weighting coefficient adjusting means for adjusting the weighting coefficient according to an operation related to information, wherein the weighting coefficient adjusting means attaches importance to the information among the operations related to information The weighting factor is adjusted so that the greater the value obtained by dividing the number of operations of the first type that is presumed to occur frequently by the elapsed time since the information was created, the greater the importance of the information. It is characterized by doing.
[0012]
In addition to the above configuration, the first type of operation may include at least one of information display, information output outside the information management apparatus, and information content change.
[0013]
Further, the weight coefficient adjusting means may change the adjustment amount of the weight coefficient according to the operation content of the first type operation.
[0014]
Further, in order to solve the above problems, the information management device according to the present invention is a weighting coefficient storage unit that stores weighting coefficients that are created according to each information and used for calculating the importance of related information, An importance calculation means for calculating the importance of the information based on a weight coefficient related to the information, and a weight coefficient adjustment means for adjusting the weight coefficient according to an operation related to the information. The above means that the importance of the information increases as the number of times of the first type operation that is presumed to occur frequently when the information is important among the operations related to the information increases. While adjusting the weighting factor, the weighting factor adjusting means may change the adjustment amount of the weighting factor according to the operation content of the first type of operation.
[0015]
Further, in addition to the above-described configuration, the weighting factor adjusting unit is configured so that the amount of change in the importance of information is larger in a display operation that requires redisplay than in a display operation that does not require redisplay. The weighting factor may be adjusted.
[0016]
Further, in addition to the above configuration, the weighting factor adjusting unit is configured so that the amount of change in the importance of the information is larger in the output operation outside the information management apparatus than in the information display operation. The weighting factor may be adjusted.
[0017]
Further, in addition to the above configuration, the weighting factor adjusting unit adjusts the weighting factor so that the information content change operation has a larger amount of change in the importance of information than the information display operation. May be.
[0018]
Further, in addition to the above configuration, the weighting factor adjusting means is configured so that the amount of change in the importance of information is greater in the output operation outside the information management device than in the information content change operation.

[0022]

[0023]
Further, in addition to the above configuration, the part specifying unit specifies an information display part as an operation part, and the weight coefficient adjusting unit includes the keyword when the operation part includes a keyword. The keyword weighting factor may be adjusted so that the degree of importance of the keyword is greater than when it is not.
[0024]
In addition to the above-described configuration, the weight coefficient adjustment unit is less important when the deleted operation part includes a keyword than when the keyword is not included. As described above, the keyword weighting coefficient may be adjusted.
[0025]
Furthermore, in order to solve the above-described problem, the information management apparatus according to the present invention includes weighting factor storage means for storing a weighting factor that is created for each piece of information and used for calculating importance of related information, An importance calculation means for calculating the importance of the information based on a weight coefficient related to the information, and a weight coefficient adjustment means for adjusting the weight coefficient according to an operation related to the information, and the weight coefficient storage The means includes keyword weight coefficient storage means for storing a keyword weight coefficient provided for each keyword constituting the information as the weight coefficient, and the importance calculation means includes the keyword weight coefficient for each keyword constituting the information. The weighting factor adjustment means calculates the importance of the information based on the keyword, and if the input character string includes a keyword, the keyword Than not contain a de, so the importance of the keyword increases, is characterized by adjusting the keyword weighting factors.
[0026]
Further, in addition to the above configuration, an identification unit for identifying the use of the input character string is provided, and the weighting factor adjusting unit may change the adjustment amount of the keyword weighting factor according to the use of the input character string. Good.
[0027]
Further, in addition to the above-described configuration, the weighting factor adjusting unit may increase the amount of change in the importance of the keyword when the use of the input character string is information search, compared with the case where the use is a new addition of information. The keyword weight coefficient may be adjusted.
[0028]
Further, in addition to the above configuration, the weighting factor adjustment unit may increase the importance of the keyword when the use of the input character string is information content correction than when the use is a new addition of information. The keyword weighting factor may be adjusted.
[0029]
Further, in addition to the above-described configuration, the weight coefficient adjustment means may be configured such that when the use of the input character string is information retrieval, the importance of the keyword is greater than when the use is information content correction. The weighting factor may be adjusted.
[0030]
In addition to the above configuration, the weight coefficient storage means includes file weight coefficient storage means for storing a file weight coefficient provided for each file, which is a storage unit of information, as the weight coefficient, and the importance level The calculation means may calculate the importance of the information based on the file weight coefficient of the file for storing information and the keyword weight coefficient constituting the information.
[0031]
Further, in addition to the above configuration, there is provided history information storage means for storing history information indicating a history of operations related to information, and the weighting coefficient adjusting means can adjust the weighting coefficient based on the history information. Good.
[0032]
In addition to the above-described configuration, the weighting factor adjusting unit may change the adjustment amount of the weighting factor according to the time when the operation is performed.
[0033]
If the weighting factor can be adjusted before the importance level calculating unit finishes calculating the importance level of the information, for example, the weighting factor adjusting unit may update the value stored in the weighting factor storage unit, You may adjust, after reading from the weight coefficient memory | storage means. Further, when a plurality of weighting factors are used when calculating the importance of certain information, at least one of the weighting factors may be adjusted. In addition, for each operation, the entire information (file) may be the operation target, or part of the information may be the operation target.
[0034]
the aboveWeighting factor storage means for storing weighting factors created according to each information and used for calculating the importance of related information, and importance for calculating importance of the information based on the weighting factor related to information A calculating unit and a weighting factor adjusting unit configured to adjust the weighting factor according to an operation related to information.In the configuration, the weighting coefficient is created according to each information, for example, for each file that is an information storage unit or for each keyword that is a unit constituting information, and is stored in the weighting coefficient storage means. In addition, the weighting coefficient adjusting unit adjusts the weighting coefficient when an operation related to information such as an operation on displayed information or an operation on a file in which information is stored is performed. Furthermore, the importance level calculation means calculates the importance level of the information based on the weighting coefficient related to the information.
[0035]
According to the above configuration, the importance of each information can be used, for example, the information to be operated, the distribution of files or keywords, or the type and timing of the operation, without the user instructing the importance. It is automatically adjusted according to the user's operation tendency. For example, if a method that increases the importance of the information every time the information is manipulated is selected as the weighting coefficient adjustment method, the more important the information, the greater the importance. As a result, the information management apparatus can calculate the importance suitable for each user without the user managing the keyword for search or managing the importance of each information. As a result, it is possible to greatly reduce the time and effort required for the user to organize information in order to find out necessary information.
[0036]
The weighting factor is created according to the information and adjusted according to the operation tendency. In this way, since the importance of each information is learned by the open learning system, the weighting coefficient of each information can be adjusted regardless of the importance of the information. Therefore, unlike the conventional technique in which each information is displayed in a layout corresponding to the degree of importance, and learning control is performed on the system-specific weight coefficient so as to match the layout instructed by the user, the applicable range is not limited. The present invention can be widely applied to information management devices that can perform operations related to information.
[0037]
Furthermore, onHistory information storage means for storing history information indicating an operation history related to the recording information, and the weighting coefficient adjusting means adjusts the weighting coefficient based on the history information.StructureIn the configuration, when an operation related to information is performed, history information indicating the operation is stored in the history information storage unit. Here, the weighting factor adjusting means can adjust the weighting factor by referring to the history information, for example, even when the time has elapsed since the operation time point, such as the time point when the user instructs the importance calculation of information. . Therefore, even if a weighting factor adjustment method is specified at the time of instructing importance calculation, the weighting factor can be adjusted by the adjustment method. As a result, the information management apparatus can calculate the importance of information more flexibly.
[0038]
In general, the importance felt by the user changes with the passage of time. Therefore, information that is determined to be important at a certain time and frequently manipulated may be determined to be less important at another time.
[0039]
the aboveThe weighting factor adjusting means is configured to change the adjustment amount of the weighting factor according to the time when the operation is performed.According to this, the adjustment amount of the weighting coefficient is changed according to the time when the operation is performed. Therefore, the adjustment amount of the weighting coefficient resulting from the operation at a specific time can be set to a value different from that at the remaining time. Accordingly, it is possible to increase the importance of information that is estimated to be important by the user at a specific time. As a result, it is possible to further reduce the trouble for the user to find desired information.
[0040]
UpThe weighting coefficient storage means includes file weighting coefficient storage means for storing a file weighting coefficient provided for each file as a storage unit of information as the weighting coefficient, and the importance calculation means stores information. Calculate the importance of the information based on the file weighting factorIn the configuration, the file weighting coefficient serving as a weighting coefficient is provided for each file serving as an information storage unit, and is adjusted according to an operation related to information. As a result, the information management apparatus can increase or decrease the importance of information in units of files.Note that the importance calculation unit may calculate the importance using other weighting factors such as a keyword weighting factor described later as long as the importance of the information is calculated based on the file weighting factor.
[0041]
Here, when a user operates information, the file is often set as an operation target, for example, by opening a file in which the information is stored and displaying the information. Accordingly, the information management device can increase or decrease the importance level for each file, thereby calculating the importance level suitable for the user's operation tendency, and the user can find necessary information earlier.
[0042]
By the way, as said information, not only a character but the information of various formats, such as an image and an audio | voice, can be considered. Among these, when information is composed of keywords that are meaningful units, such as information consisting of characters, it is effective to provide a weighting coefficient corresponding to the keywords.
[0043]
IeThe weight coefficient storage means includes keyword weight coefficient storage means for storing, as the weight coefficient, a keyword weight coefficient provided for each keyword constituting the information, and the importance degree calculation means includes each of the importance degree calculation means. Calculate the importance of the information based on the keyword weighting factor of the keywordIn the configuration, a keyword weighting factor that is a weighting factor is provided for each keyword constituting the information, and is adjusted according to an operation related to information including the keyword. Therefore, when certain information is operated, the importance of other information including the keyword in the information is adjusted.If the importance of information is calculated based on the keyword weighting factor, other weighting factors such as the file weighting factor may be used together.
[0044]
Here, information that includes many keywords in common often has contents similar to each other, and when a user determines that certain information is important, the information having contents similar to the information is also determined to be important. Often to do. Therefore, by adjusting the keyword weighting coefficient, it is possible to calculate the degree of importance suitable for the operation tendency of the user, and the user can find necessary information earlier.
[0045]
By the way, when the importance calculation means calculates the importance based only on the file weight coefficient, when certain information is operated, only the importance of the information changes, and the importance of the other information does not change. Therefore, it may take time to search for information having contents similar to the information. On the other hand, when the importance is calculated based only on the keyword weighting factor, the importance of the operated information is close to the importance of information having contents similar to the information, and it becomes difficult to find the operated information. There is a fear.
[0046]
On the other handAnd aboveRecordThe weight coefficient storage means includes file weight coefficient storage means for storing a file weight coefficient provided for each file as a storage unit of information as the weight coefficient, and the importance calculation means is a file for storing information. The importance of the information is calculated based on the file weighting coefficient and the keyword weighting coefficient constituting the information.In the configuration, the importance level calculation means calculates the importance level based on the file weight coefficient and the keyword weight coefficient. Therefore, when certain information is manipulated, the importance of information having contents similar to the information can be changed, and the difference between the importance of manipulated information and the importance of the similar information is maintained. Can do. As a result, it is possible to realize an information management apparatus that can discover both information directly operated and similar information earlier.If both weighting factors are used for calculating the importance of information, other weighting factors may be used in combination.
[0047]
Also,UpThe weighting factor adjusting means adjusts the weighting factor so that the importance of the information increases as the information display time increases.StructureAccording to the above, when the information is displayed, the weighting factor adjusting means adjusts the weighting factor according to the display time. As a result, the weighting factor can be adjusted so that information with a long display time has a relatively high importance.
[0048]
In general, information that is determined to be important by the user is frequently referred to and displayed longer than information that is determined to be unnecessary. Here, in the above configuration, since the weighting coefficient is adjusted according to the display time, it is possible to calculate the degree of importance suitable for the operation tendency of the user, and the user can find necessary information earlier.
[0049]
Note that the display time may be, for example, the time from when it is displayed on the screen until the display ends, or if the display device can display a plurality of windows in an overlapping manner, the display time is the highest. The time displayed in the window (active window) may be set as the display time. In addition, the display time in each overlap state is counted separately, and the display time is a value obtained by adding a weight corresponding to the overlap state to each display time so that the weight is larger when the overlap is higher. Good.
[0050]
MoreOnThe weighting coefficient adjusting means increases the importance of the information as the number of operations of the first type preliminarily estimated to occur frequently when the information is important among the operations related to the information. Adjust the weighting factor so thatStructureAccording to the configuration, for example, the user determines that the information is important, such as an operation related to display, an operation related to content change, an operation related to information retrieval, and an operation to output information outside the information management apparatus. If an operation that occurs frequently is performed, the importance of the information increases. As a result, the information management apparatus can calculate the degree of importance suitable for the operation tendency of the user, and the user can find necessary information earlier.
[0051]
Here, in general, a user often places importance on information that has been recently created and frequently used. UpThe weighting coefficient adjustment means calculates the number of times of the first type of operation that is presumed to occur frequently when the information is important among the operations related to the information by the elapsed time after the information is created. The weight coefficient is adjusted so that the greater the divided value, the greater the importance of the information.In the configuration, when an operation that is frequently performed when the information is determined to be important is performed, the importance of the information increases. Moreover, the importance of the information becomes smaller as the elapsed time from the creation of the information increases. As a result, even when the number of operations is the same, the importance of recently created information can be increased, and the information management apparatus can calculate the importance closer to the sense of the user.
[0052]
further,UpThe first type of operation includes at least one of information display, information output outside the information management apparatus, and information content change.StructureAccording to the configuration, when an information display operation, an output operation, or a content change operation is performed, the importance of the information increases. Here, examples of the display operation include display start and display stop, whole display, partial display, display part change in information, enlargement and reduction, or display position change on the display screen. The output operation includes, for example, printing, communication, or recording on a recording medium. Furthermore, the content change operation includes content addition, content correction, partial copying, partial deletion, and the like. Among operations related to information, these operations are frequently performed when the user attaches importance to the information. As a result, by adopting these operations as the first type of operation, the information management apparatus can calculate the importance closer to the sense of the user.
[0053]
By the way, as described above, there are various types of operations related to information, and each type of operation has an influence on the frequency of operation and the influence of one operation on the importance of information. Often different.
[0054]
For example, in the case of editing a certain document, the number of operations for character input is extremely large, and the importance of information does not change much by one operation. Since the process is performed when the user determines that the information needs to be updated, the importance of the information changes relatively greatly even though the number of operations is relatively small.
[0055]
Therefore, when adjusting the weighting factor according to the operation, if the adjustment is made uniformly for each type of operation, there is a risk that a deviation will occur between the importance calculated by the information management device and the importance felt by the user. is there.
[0056]
On the other handAnd aboveThe weight coefficient adjusting means changes the adjustment amount of the weight coefficient according to the operation content of the first type operation.StructureAccording to the above, the adjustment amount of the weighting coefficient changes according to the type of operation. As a result, the deviation between the importance calculated by the information and the importance felt by the user can be reduced, and the information management apparatus can calculate the importance of the information more accurately.
[0057]
Here, when displaying a lot of information at the same time or displaying a large amount of information, it is difficult to display all necessary information on the screen at the same time. Therefore, it is often the case that a plurality of pieces of information are superimposed and displayed, or only a part of the information is displayed. In this case, in order to display a desired portion, the user rewrites the screen, or displays information out of the display area of the screen again using a back scroll function or the like. As a result, as the information is more important to the user, the information display state is frequently changed and redisplayed.
[0058]
the aboveThe weighting factor adjusting means adjusts the weighting factor so that the amount of change in the importance of information is larger in a display operation that requires redisplay than in a display operation that does not require redisplay.According to the configuration, the more frequently the information is redisplayed, the higher the importance. Thereby, the information management apparatus can calculate the importance of information more accurately.Note that examples of the display operation that requires re-display include a back scroll operation and a display position change operation.
[0059]
MaThe topThe weighting factor adjusting means adjusts the weighting factor so that the amount of change in the importance of information is greater in the operation of outputting information outside the information management device than in the operation of displaying information.StructureAccording to Sei, the importance of information that has been output is relatively increased. Here, when the user outputs information or a part of the information, the user is often intended to refer to many people, and the information is more than the information used in the information management device. It is important. As a result, the information management apparatus can calculate the importance closer to the sense of the user.
[0060]
oneWay upThe weighting factor adjusting means adjusts the weighting factor so that the amount of change in the importance of information is greater in the information content changing operation than in the information displaying operation.StructureAccording to the configuration, when the contents are changed, the importance of the information becomes larger than when the contents are simply displayed. Here, when the user changes the contents of the information, the user often determines that this information is important. Therefore, the information management apparatus can calculate the importance of the information more accurately by relatively increasing the importance of the information whose contents are changed.
[0061]
further,UpThe weighting factor adjusting means adjusts the weighting factor so that the amount of change in the importance of the information becomes larger in the operation of outputting the information outside the information management apparatus than in the operation of changing the information content.StructureAccording to the configuration, the importance is relatively increased in the order of the output information, the information whose contents are changed, and the displayed information. Therefore, the information management apparatus can calculate the importance more accurately.
[0062]
on the other handThe weight coefficient adjustment means is configured so that, when an operation related to information is performed and a second type operation that is presumed to occur frequently when the information is unnecessary is performed, the importance of the information is reduced. , Adjust the above weighting factorIn the configuration, when the second type operation is performed, the importance of the information is lower than when the operation is not performed. Here, the second type of operation is frequently performed when the user determines that information is unnecessary. Therefore, the information management apparatus can calculate the importance level adapted to the operation tendency of the user, and the user can find necessary information earlier.Note that examples of the second type of operation include an operation for deleting information, such as an operation for deleting a file in which information is stored.
[0063]
By the way, when the operation target is a part of the information, the user often pays attention to the operation part in the information. Therefore, EmotionWhen the weight coefficient corresponds to a unit smaller than the information, the information management device is close to the user's sense by changing the adjustment amount of the weight coefficient depending on whether or not it is included in the operation part. Importance can be calculated.
[0064]
In particular,Above informationPart specifying means for specifying the operation part of the report, and the weight coefficient adjusting means adjusts the keyword weight coefficient of the keyword included in the operation part.StructureAccording to the configuration, the adjustment amount of the keyword weighting coefficient is changed depending on whether or not it is included in the operation part. Thereby, the information management apparatus can calculate the importance close to the sense of the user.
[0065]
further,UpThe part specifying means specifies the information display part as the operation part, and the weight coefficient adjusting means is configured such that when the operation part includes a keyword, the keyword is included rather than when the keyword is not included. Adjust the keyword weighting factor so that the importance ofStructureAccording to this, the importance of the keyword is greater when it is included in the display part. Therefore, the more frequently the keywords are displayed, the greater the importance. As a result, the information management apparatus can calculate the importance level close to the user's sense.
[0066]
Also,UpThe weighting factor adjustment means adjusts the keyword weighting factor so that when the deleted operation part includes a certain keyword, the importance of the keyword is smaller than when the keyword is not included. YouStructureAccording to this, the importance of the keyword is smaller when it is included in the deleted part. Therefore, the importance is relatively reduced as the keyword is frequently deleted as a result of the information content correction. As a result, the information management apparatus can calculate the importance level close to the user's sense.
[0067]
By the way, the keyword is included not only in the information but also in a character string input by the user such as a character string used when searching for information. Here, generally, when a user inputs a character string, the user himself / herself inputs a character string that the user considers important. Therefore, if the amount of change in the importance of the keyword is changed depending on whether it is included in the user's input character string, the importance close to the user's sense can be calculated.
[0068]
In particular,UpThe weighting coefficient adjusting means adjusts the keyword weighting coefficient so that when the keyword is included in the input character string, the importance of the keyword is higher than when the keyword is not included.StructureAccording to Sei, keywords that are frequently included in the input character string have a relatively high importance. Thereby, the information management apparatus can calculate the importance close to the sense of the user.
[0069]
MoreOnIdentification means for identifying the use of the input character string, and the weight coefficient adjustment means changes the adjustment amount of the keyword weight coefficient according to the use of the input character string.StructureAccording to the above, the adjustment amount of the keyword weighting coefficient is changed according to the use of the input character string. Here, for example, new input of information, correction of information content, search, etc. can be mentioned, and the length of the input character string is different from the degree to which the user attaches importance to the keyword in the input character string. There are many. Therefore, the information management apparatus can calculate the importance close to the user's sense by changing the adjustment amount according to the application.
[0070]
Also,UpThe weighting factor adjusting means adjusts the keyword weighting factor so that when the use of the input character string is information retrieval, the amount of change in the importance of the keyword is larger than when the use is a new addition of information.StructureAccording to this, keywords used for information retrieval have a relatively higher importance than keywords used for new input. Here, when searching for information, only keywords that are particularly important to the user are often input, and for new input, not only keywords that are particularly important to the user but also keywords related to the keywords. Are often entered. Therefore, the information management device can calculate the importance level close to the user's sense by increasing the importance level of the keyword used for the information search.
[0071]
on the other hand,UpThe weighting factor adjustment means adjusts the keyword weighting factor so that the importance of the keyword is greater when the use of the input character string is the modification of information content than when the use is a new addition of information.StructureAccording to this, the keyword used for content correction is relatively more important than the keyword used for new input. Here, in many cases, at the time of content correction, the length of the input character string is shorter than that at the time of new input, and the content rate of keywords that are more important is high. Therefore, the information management apparatus can calculate the importance close to the user's sense by increasing the importance of the keyword used for content correction.
[0072]
further,UpThe weighting factor adjusting means adjusts the keyword weighting factor so that the importance of the keyword is greater when the usage of the input character string is information retrieval than when the usage is information content modification.StructureAccording to this, the keyword used for information retrieval has a greater relative importance than the keyword used for content correction. Here, in many cases, the input character string at the time of information retrieval is shorter in length than the input character string at the time of content correction, and the content rate of the keyword regarded as important is high. Therefore, the information management apparatus can further increase the importance of the keyword used for information retrieval, and can calculate the importance close to the user's sense.
[0073]
Also,Main departureIn order to solve the above problems, a recording medium according to MingIn addition, a program for operating a computer is recorded as each means of each information management apparatus.It is characterized by having.
[0074]
When the program of the above configuration is executed on a computer,Above informationSimilar to the information management apparatus, a weighting factor is created according to the information and adjusted according to the tendency of the operation. Therefore, even if the importance of each information is not managed, the information management device can calculate the importance suitable for each user, and greatly reduces the trouble of organizing the information to find the necessary information for the user. Can be reduced.
[0075]
Also, since the importance of each information is learned by an open learning system, the weighting coefficient of each information can be adjusted regardless of the importance of the information. Therefore, the application range is not limited, and the present invention can be widely applied to information management apparatuses that can perform operations related to information.
[0076]
DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
An embodiment of the present invention will be described below with reference to FIGS. That is, the information management system according to the present embodiment is a system that manages various types of information while changing the importance of information according to the user. For example, the user feels that information related to a certain matter is necessary. When, for example, information with high importance is highlighted and displayed, it is used to assist in finding the information.

As shown in FIG. 1, an information management system 1 according to the present embodiment includes an information management device 2 that stores information D, a display device 3 that displays information D, and an information management device 2 such as a keyboard and a mouse. And an external input / output device 5 that exchanges information D with the outside of the information management device 2, such as a network 5a, a disk device 5b, or a printer 5c, for example. Based on this, the importance level Xs calculated by the information management apparatus 2 can be made closer to the importance level Xu felt by the user.
[0078]
Specifically, the information management apparatus 2 stores, as the storage unit 11, an information storage unit 11a that stores the information D itself, and a weighting factor P that is created according to the information D and that calculates the importance of the information D. The weight coefficient storage unit 11b and the history storage unit 11c updated according to the user's operation are provided. The weight coefficient storage unit 11b corresponds to the weight coefficient storage means, the file weight coefficient storage means, and the keyword weight coefficient storage means described in the claims. The history storage unit 11c corresponds to history information storage means.
[0079]
The information storage unit 11a according to the present embodiment stores at least a character string field as the information D. Note that the information D may include fields other than characters, such as pictures and voices.
[0080]
In addition, the weight coefficient storage unit 11b uses, as the weight coefficient P, a file weight coefficient FP provided for each file F, which is a storage unit of each information D, and a keyword provided for each keyword K constituting each information D. Stores weighting coefficient KP and some information D_A Importance Xs_A Is the information D_A File F where is stored_A File weighting factor FP_A And the information D_A K that constitutes_A1Keyword weighting factor KP ..._A1It is calculated by adding the sum of…. Hereinafter, for convenience of explanation, the file weight coefficient FP and the keyword weight coefficient KP used for calculating the importance of the information D are referred to as the weight coefficient P of the information D.
[0081]
Furthermore, the history storage unit 11c stores information for adjusting each weighting factor P according to the operation of the user, such as the display time and the number of operations, for example, which will be described in detail later.
[0082]
On the other hand, a display control unit 12a, an input control unit 12b, and an information input / output control unit 12c are provided as the input / output control unit 12 for controlling the devices 3 to 5. In addition, as an analysis unit 13 for analyzing information D and operations, a display analysis unit (part specifying means) 13a for analyzing the display of the display device 3 based on input / output of the display control unit 12a, and an operation input device 4 From the operation input unit 4 and the external input / output device 5 through the input control unit 12b and the information input / output control unit 12c. And an information analysis unit 13c that analyzes the information D to be calculated and calculates an initial value of the weighting coefficient P.
[0083]
Further, as the calculation unit 14 for calculating the importance degree Xs, based on the weighting factor P, a weighting factor processing unit (weighting factor adjusting unit) 14a that processes the weighting factor P stored in the weighting factor accumulating unit 11b. And an importance level calculation unit (importance level calculation means) 14b for calculating the importance level Xs. Furthermore, an information control unit (identification means) 15 that controls each of the units 11 to 14 is provided.
[0084]
Each of the units 11 to 15 may be a functional module realized by a computer executing a predetermined program, or may be unique hardware. However, when realized as a functional module, the information management apparatus 2 can be realized simply by distributing a recording medium on which the program is recorded.
[0085]
In the above configuration, the operation of each unit when inputting information D will be described with reference to FIG. That is, when information D is input to the information management apparatus 2 in S1, the information management apparatus 2 generates a weighting coefficient P for calculating the importance level Xs of each information D in S2.
[0086]
Specifically, as illustrated in FIG. 3, when the user generates information D, in S <b> 11, the input control unit 12 b of the information management device 2 determines that the input from the operation input device 4 is information D. Then, the information D generated by the user is output to the information analysis unit 13c. On the other hand, when the information D is taken from the external input / output device 5, in S12, the information input / output control unit 12c of the information management device 2 receives the information D from the external input / output device 5 such as the network 5a or the disk device 5b. Receive it and output it to the information analyzer 13c.
[0087]
In any case, the information analysis unit 13c accumulates the received information D in the information accumulation unit 11a of the storage unit 11 in S13. As long as the information D includes a region D1 including text information, for example, as illustrated in FIG. 4, the information D may include a region D2 including information other than a character string, such as an image. A file weight coefficient FP, which is one of the weight coefficients P, is generated corresponding to the file F, which is the storage unit of information D, and stored in the weight coefficient storage unit 11b (S14). Note that the initial value of the file weight coefficient FP may be set to a different value depending on the acquisition route of the information D such as the operation input device 4 or the network 5a, or may be a constant value.
[0088]
In S15, the information analysis unit 13c extracts text information from the input information D. In S16, the keyword K is cut out from the extracted text information by character string processing. In S17, the information analysis unit 13c weights each keyword K according to, for example, the appearance frequency or the appearance location in the information D. Thereby, for example, as shown in Table 1 below, the initial value of the weighting coefficient KP of each keyword K is calculated. When weighting is performed according to the appearance frequency, the appearance frequency in the other information D stored in the information storage unit 11a is also referred to.
[0089]
[Table 1]

[0090]
As a result, the keyword K having a high appearance frequency of the information D and appearing on a large amount of information D on the average is given a lower weight than the keyword K having a low appearance frequency. When the text information is structured and is composed of areas such as a summary or text, the keyword K included in the summary area is given a higher weight than the keyword K included in the text area. In the above description, the method based on the appearance frequency and the appearance location is exemplified as an example of the method for calculating the initial value of the keyword weight coefficient KP. However, the present invention is not limited to this, and various methods can be adopted.
[0091]
On the other hand, in FIG. 2, when the user instructs the importance calculation of the information D (YES in S3), the information management device 2 determines the importance Xs of each information D based on the weighting coefficient P in S4. In S5, for example, the importance Xs calculated by the information management device 2 is used, such as highlighting and displaying the information D with the highest importance Xs, or ranking and displaying the information D with the highest importance Xs. Present it so that the person can grasp it. As a result, the information D that the information management device 2 determines is more important for the user to acquire. As a result, the user can extract desired information D with less effort as the difference between the importance Xs calculated by the information management device 2 and the importance Xu felt by the user is smaller. Note that S4 shown in FIG. 2 corresponds to the importance calculation step described in the claims, and S7 corresponds to the weighting coefficient adjustment step.
[0092]
As described above, in the information management apparatus 2 according to the present embodiment, as an example of the weighting factor P, the keyword weighting factor KP that is a unit constituting the information D and the file F that is a storage unit of the information D are provided. The file weighting factor FP is used, and the information management device 2 uses the sum of the keyword weighting factors KP of each keyword K included in a certain information D and the file weight of the file F storing the information D in S4. The importance Xs of the information D is calculated by adding the coefficient FP.
[0093]
Here, since the initial value of the weighting coefficient P calculated in S2 is determined from a predetermined calculation method and the information D input in S1, if each is the same, each information management device The same between the two. Accordingly, the importance level Xs of the information D calculated from these values is the same value between the information management apparatuses 2. On the other hand, since the importance level Xu of the information D felt by the user is different for each user, the importance level Xs of the information D presented by the information management device 2 in the state where the weighting factor P remains at the initial value. Deviation occurs between the two.
[0094]
However, the information management apparatus 2 according to the present embodiment, for example, when an operation related to the information D such as display or content change of the information D or search or output is performed (in the case of YES in S6). In S7, the weighting coefficient P for calculating the importance Xs of the information D is adjusted.
[0095]
Thus, for example, the information management apparatus 2 changes to the importance level Xu felt by the user even though an operation for managing the importance level Xs of the information D such as inputting the importance level of the keyword is not performed. The importance degree Xs calculated by itself can be made closer. As a result, the user can take out the desired information D with less effort without managing the importance level Xs of the information D.
[0096]
Here, as a method of adjusting the weighting factor P in S7, for example, if it is a method of adjusting according to the operation related to the information D such as the content and frequency of the operation, the time when the information D is displayed by the operation, Although any method can be applied, in this embodiment, weighting by display time will be described as an example of an adjustment method.
[0097]
Specifically, as shown in FIG. 5, in S21, certain information D_A When the user instructs the display, the instruction is identified by the operation analysis unit 13b and transmitted to the information control unit 15 (S22). Upon receiving the notification in S23, the information control unit 15 receives the information D_A A command for performing the screen display is generated and transmitted to the display control unit 12a. As a result, the display device 3 receives information D._A Is displayed.
[0098]
Further, in S24, the information control unit 15 sends the information D to the display analysis unit 13a._A Is displayed, and in S25, the display analysis unit 13a displays the information D._A Display time measurement starts.
[0099]
On the other hand, in S26, the user receives information D._A Is instructed by the operation analysis unit 13b and transmitted to the information control unit 15 (S27). In S28, the information control unit 15 performs information D_A A command for ending the screen display is generated and transmitted to the display control unit 12a. As a result, information D_A The screen display ends.
[0100]
Furthermore, the information control unit 15 according to the present embodiment performs information D in S29._A Is notified to the display analysis unit 13a. On the other hand, in S30, the display analysis unit 13a performs information D based on the notification._A The display time measurement of is terminated.
[0101]
Here, in the history storage unit 11c, a total display time T indicating the total of the time when the information D was displayed in the past is stored corresponding to each information D. In S31, the display analysis unit 13a performs information D_A Total display time T_A Is added to the current display time. The result of this addition is the new total display time T_A Is stored in the history storage unit 11c. Note that the total display time T is displayed when, for example, it is displayed for the first time._A Is not stored in the history storage unit 11c, the display analysis unit 13a sets the current display time as a new total display time T._A Store as.
[0102]
Furthermore, the weight coefficient processing unit 14a receives the information D stored in the history storage unit 11c in S32._A Total display time T_A Referring to the total display time T_A The longer the is, the information D_A Importance Xs_A The information D so that the_A Weighting factor P_A Adjust.
[0103]
For example, as shown in Table 2 below, information D_B Total display time T_B But information D_A Total display time T_A Is twice the weight coefficient processing unit 14a, the information D_A Weighting factor P_A Information D_B Weighting factor P_B Increase. In Table 2, for comparison, only the total display time T is different. For example, information D having the same other conditions such as a weighting factor P before adjustment._A ・ D_B ・ D_C And the weighting factor ratio is the weighting factor P_A It is a ratio when the value of 1 is 1.
[0104]
[Table 2]

[0105]
In the present embodiment, since the file weight coefficient FP and the keyword weight coefficient KP are used as the weight coefficient P, the information D_B File F where is stored_B File weighting factor FP_B Is information D_A File F where is stored_A File weighting factor FP_A Information D_B Keyword K included in_B1Keyword weight coefficient KP_B1Is the keyword K included in information A_A1Keyword weight coefficient KP_A1Increases by a factor of two. Similarly, information D_C Weighting factor P_C Is information D_A Weighting factor P_A It increases to 1.5 times.
[0106]
Since the processes of S21 to S32 are also performed on other information D, the importance Ds increases relatively as the information D with a longer total display time T, and the importance increases as the information D with a shorter total display time T. Xs relatively decreases.
[0107]
In general, the user of the information management device 2 operates the operation input device 4 mainly while looking at the information D displayed on the display screen of the display device 3. Therefore, as the user pays attention to certain information D, the display time of the information D often becomes longer. Here, the information management apparatus 2 adjusts the weighting coefficient P by estimating that the user attaches importance to the information D as the total display time T of the information D is longer. As a result, even if a deviation occurs between the importance level Xu of the information D perceived by the user and the importance level Xs calculated by the information management apparatus 2 at the time of S2 shown in FIG. Each time the processes of S3 to S7) shown in FIG. 2 are repeated, the deviation is reduced. As a result, the information management apparatus 2 can present the importance level Xs suitable for each user.
[0108]
In this example, both the file weight coefficient FP and the keyword weight coefficient KP are adjusted, but only one of them may be adjusted. However, when adjusting only the file weight coefficient FP, the information D displayed by the user is displayed._A Importance Xs_A Only adjusted. Therefore, other information D_B Is the information D_A Even if it is similar to_B Importance Xs_B Does not change, the information D_B It may take time and effort to search for.
[0109]
On the other hand, when adjusting the keyword weighting coefficient KP, the user simply operates by paying attention to one piece of information D, and information D having similar contents._B Importance Xs_B Also rises. As a result, the user receives the information D_B Makes it easier to discover. However, when adjusting only the keyword weighting coefficient KP, both information D_A ・ D_B Importance Xs_A ・ Xs_B Changes in the same manner, so that the user can directly indicate the information D_A The other information D_B It becomes difficult to distinguish from. As a result, the directly designated information D_A If you want to search for, there is a risk of taking time and effort.
[0110]
On the other hand, in the present embodiment, two weighting factors FP and KP are used together as the weighting factor P, and both are adjusted. As a result, the directly designated information D_A Similar information D without interfering with the search for_B Can be easily discovered.
[0111]
In the above example, the weighting factor P is adjusted so that the increasing rate of the weighting factor P is proportional to the total display time T, but the present invention is not limited to this. Instead of the increase rate, it may be adjusted by an increase width, or may be adjusted using another mathematical formula. When compared only when the total display time T is different, the same effect as in the present embodiment can be obtained if the adjustment method is such that the importance level Xs of the information D increases as the total display time T increases.
[0112]
However, in order for the information management device 2 to calculate the importance level Xs closer to the user's sense, for example, as shown in FIG. It is preferable to adjust P. In this case, the weighting factor P gradually increases while the total display time T is short, and the slope of the weighting factor P becomes steep when the total display time T increases. Further, the weight coefficient P is a predetermined upper limit value P_LIM As the value approaches, the weighting factor P increases gently. Thereby, the fluctuation | variation of the importance Xs resulting from the total display time T can be brought close to a user's sense.
[0113]
Moreover, if the time after the information management apparatus 2 starts operation | movement becomes long, the total display time T of each information D will become long, and there exists a possibility that the importance Xs of each information D may approach. Therefore, when the display not related to the file F or the keyword K continues, it is better to gradually decrease the weighting coefficient P (KP · FP) of the file F or the keyword K as shown in FIG. Thereby, even if time passes, importance Xs of each information D can be distributed over a wide range, and it becomes easy for a user to find desired information D.
[0114]
In the above example, the total display time T of the information D itself is stored in the history storage unit 11c. However, the present invention is not limited to this. For example, the time when the display start of each information D is instructed and the time when the display stop of each information D is instructed may be stored to calculate the total display time of each information D. Further, when the display device 3 can perform multi-window display and can display a plurality of pieces of information D in an overlapping manner, the display overlapping order may be weighted when the display time is measured. In any case, if the weighting coefficient P of the information D can be adjusted according to the display time of the information D, the same effect as in the present embodiment can be obtained.
[0115]
[Second Embodiment]
By the way, when the weighting coefficient P is adjusted based only on the total display time T of the information D, for example, the importance Xs of the information D displayed on the background of the screen also increases. In addition, for example, even when the user is not paying attention to the information D, such as when the user is away from the information management device 2, there is a possibility that the importance degree Xs increases.
[0116]
In this embodiment, the number of operations of information D will be described with reference to FIGS. 6 to 9 as another measure for adjusting the weighting factor P. FIG. Various operations exist for the operation on the information D. In the following, a display start instruction and a display stop instruction for the information D will be described as examples. In this case, for example, processing related to the user's instruction and screen display is the same as the processing in FIG. 5, and thus the same processing is denoted by the same reference numeral and description thereof is omitted. Further, in the present embodiment and the following embodiments, the configuration of the information management apparatus 2 is the same as that of the first embodiment, and only the operation of each part is different.
[0117]
That is, in S21 to S24 shown in FIG. 8, the information management device 2 sends information D to the display device 3 in accordance with a user instruction._A The information control unit 15 notifies the display analysis unit 13a of the start of display. On the other hand, in step S41, the display analysis unit 13a according to the present embodiment stores information D stored in the history storage unit 11c._A Number of operations m_A Increase by one.
[0118]
When the user gives an instruction to end the display, the information management device 2 sends information D to the display device 3 in S26 to S29._A The information control unit 15 notifies the display analysis unit 13a of the display stop. In this case, as in S41 above, in S42, the information D_A Number of operations m_A Increase by one. Thereby, the operation memory m of each information D is stored in the history storage unit 11c.
[0119]
Further, the weight coefficient processing unit 14a receives the information D stored in the history storage unit 11c in S43._A Number of operations m_A Refer to the number of operations m_A The more information, the more information D_A Importance Xs_A The information D so that the_A Weighting factor P_A Adjust.
[0120]
For example, as shown in Table 3 below, information D_B Number of operations m_B But information D_A Number of operations m_A 2, the weighting coefficient processing unit 14a performs the information D similarly to S32 shown in FIG._A Weighting factor P_A Information D only twice_B Weighting factor P_B Increase. In Table 3 below, for comparison, the number of operations m_A Information D that is different only in other conditions_A ・ D_B ・ D_C Is illustrated. The weighting factor ratio is the weighting factor P_A Is the ratio when.
[0121]
[Table 3]

[0122]
Since the processing of S21 to S43 is also performed on other information D, the importance level Xs is relatively increased as the information D has a higher operation count m, and the importance level Xs is higher as the information D has a lower operation count m. Relatively decreases.
[0123]
Here, even if the information D is displayed on the screen, the information D that is not operated by the user is often less important than the information D that is frequently operated. For example, information D that is displayed as a screen background and is not operated is often displayed in the foremost window on the screen and is less important than information D that is frequently operated. Even if the information D is displayed for a long time, the user may be away from the information management device 2.
[0124]
The information management apparatus 2 according to the present embodiment adjusts the weighting coefficient P by estimating that the user attaches importance to the information D as the number of operations m of the information D increases. Therefore, the weighting factor P can be adjusted regardless of the length of the period during which the user is away from the information management device 2. In addition, since the weighting coefficient P is adjusted according to the number of operations m, even when the adjustment based on the total display time T is used together with the adjustment from the information management apparatus 2 as in the first embodiment. It is possible to relatively suppress fluctuations in the weighting factor P due to the distant period. As a result, the importance level Xs calculated by the information management device 2 can be brought closer to the importance level Xu felt by the user.
[0125]
In the above description, the case where the display start operation and the stop operation are counted has been described as an example. However, the present invention is not limited to this. The same effect can be obtained by counting the types of operations presumed that the information D is important for the user. As an example, for example, a type of operation for changing the display state, such as redisplay or enlarged display, for example, a type of operation for changing the content of the information D, such as correction or addition of the content of the information D, partial copying, or partial deletion. For example, there are types of operations that are output to the outside of the information management apparatus 2, such as copying, printing, or transmission to an external recording medium. Furthermore, examples of the operation target include the displayed information D, a part of the information D, or a file F that stores the information D. For example, when counting the number of operations of the file F, the user uses the file F_A The number of operations m of the file F each time_A Are added one by one, and the weighting coefficient P of the information D stored in the file F is adjusted according to the number of operations m of each file F. In any case, since the types of operations on which the user attaches importance to the information D can be estimated in advance, the information management apparatus 2 determines the number of operations when these types of operations are performed. Counting can adjust the weighting factor P of the information D related to the operation.
[0126]
As in the first embodiment, various methods such as an increase width, an increase rate, a proportional relationship, and an arbitrary function can be adopted as a method for adjusting the weighting coefficient P according to the number of operations m. In any case, the same effect as in the present embodiment can be obtained as long as the adjustment method increases the importance Xs of certain information D as the number of operations increases.
[0127]
However, as in the first embodiment, as shown in FIG. 6, it is more important that the weighting factor P is adjusted so as to change in an S shape with respect to the number of operations m. Can be brought closer to the user's sense. Further, as shown in FIG. 7, when an operation not related to the file F or the keyword K continues, the desired information D can be obtained by gradually decreasing the weighting factor P (KP · FP) of the file F or the keyword K. It becomes easy to discover.
[0128]
On the other hand, when the user performs an operation of a type in which it is assumed that the information D is unnecessary for the user, such as deleting the information D, for example, as shown in FIG. Accordingly, it is better to reduce the weighting factor P of the information D. Since this type of operation can also be estimated in advance, the information management apparatus 2 can adjust the weight coefficient P of the information D related to the operation without any trouble when these types of operations are performed.
[0129]
[Third Embodiment]
By the way, 2nd Embodiment demonstrated the case where each operation was counted equally as an example of how to count operation frequency. However, the actual operation includes a specific type of operation that frequently appears when the user attaches importance to the information D, such as a back scroll operation. Therefore, when the weighting factor P is adjusted in the same manner when the specific type of operation is performed and when the remaining operation is performed, the user feels the importance Xs calculated by the information management device 2. There is a possibility that a deviation from the importance level Xu occurs.
[0130]
On the other hand, in this embodiment, for example, the case where the weighting coefficient P is adjusted according to the operation content of the information D, such as counting the specific types of operations, will be described with reference to FIGS. Hereinafter, as an example of the specific operation, an operation for redisplaying the same portion in the information D such as a back scroll operation will be described.
[0131]
That is, in S51 shown in FIG._A Part A inside_A1In S52, the information control unit 15 determines that the part A is based on the user's instruction in S52._A1Create a directive to display. In response to the command, the display control unit 12a displays information D on the screen of the display device 3, for example, as shown in FIG._A Indicated part A of_A1Is displayed.
[0132]
Furthermore, the information control unit 15 determines that the part A in S53._A1Is notified to the display analysis unit 13a. In addition, the display analysis unit 13a determines that the part A in S54._A1Partial information B indicating_A1Is stored in the history storage unit 11c, the portion A_A1It is determined whether or not has been displayed in the past. For example, in the example shown in FIG. 12, the partial information B stored in the history storage unit 11c._A2Is part A_A2The part A currently displayed_A1Is different. Thus, the above part A_A1Partial information B indicating_A1Is not stored in the history storage unit 11c, the display analysis unit 13a_A1Is determined not to be displayed in the past. In this case, the display analysis unit 13a performs partial information B_A1Is stored in the history storage unit 11c (S55).
[0133]
On the other hand, part A_A1Is displayed in the past (in the case of YES in S54 above), for example, as shown in FIG._A1Partial information B indicating_A1Is already stored in the history storage unit 11c. In this case, the display analysis unit 13a indicates that the user has information D_A It is determined that a re-display operation has been performed for information D_A Redisplay operation count d_A Increase by one. Redisplay operation count d_A Is stored in the history storage unit 11c (S56).
[0134]
Furthermore, the weighting coefficient processing unit 14a performs information D in S57._A Redisplay operation count d_A , The number of redisplay operations d_A The more information, the more information D_A Importance Xs_A The information D so that the_A Weighting factor P_A Adjust.
[0135]
For example, for comparison, the number of redisplay operations d_A Information D that is different only in other conditions_A ・ D_B As an example, information D_B Redisplay operation count d_B But information D_A Redisplay operation count d_A 2, the weighting coefficient processing unit 14a performs the information D as in Table 3 above._A Weighting factor P_A Information D only twice_B Weighting factor P_B Increase.
[0136]
Since the processing of S51 to S57 is also performed on other information D, the information D having a larger redisplay operation count d, the importance Xs is relatively increased, and the information D having a smaller redisplay operation count d is decreased. The importance level Xs decreases relatively. Thereby, the information management apparatus 2 can calculate the importance Xs close to the user's sense.
[0137]
In the above description, the number of redisplay operations d is counted, but the present invention is not limited to this. If the operation is frequently performed when the user attaches importance to the information D, the same effect can be obtained even when other operations are counted as a predetermined specific type of operation.
[0138]
Further, a plurality of types of operations may be counted as specific types of operations, and the weighting coefficient P may be changed for each operation. For example, as the specific type of operation, an operation for displaying the information D, an operation for correcting the content of the information D, an operation for copying the information D to a portable recording medium such as a floppy disk, an e-mail, etc. The operation for communicating information D and the operation for printing information D are each counted. Further, the increasing rate of the weighting factor P during the display operation is 1, the increasing rate of the weighting factor P during the correcting operation is 1.5, the increasing rate during the copying operation is 2, and the increasing rate during the communication operation is 2.5. The increase rate of the weighting factor P for each operation is changed such that the increase rate during the printing operation is 3 or the like.
[0139]
Generally, when an operation for outputting the information D to the outside of the information management apparatus 2 such as printing, communication, or copying of the information D is performed, the user may try to make the information D available to many people. In many cases, it can be presumed that the user attaches importance to the information D as compared with the case where the information D is processed inside the information management apparatus 2. Further, since the user often does not correct the contents of the information D unless necessary, the user attaches more importance to the information D whose contents are corrected than the information D that is simply displayed. I guess that. Therefore, as described above, if the weighting factor P of the information D is adjusted by assigning weights in the order of display operation, correction operation, copying operation, communication operation, and printing operation, the information management apparatus 2 can sense the user. It is possible to calculate the importance Xs closer to.
[0140]
In the above description, the case where the number of operations is counted separately has been described as an example. However, the present invention is not limited to this. For example, the printing operation may be counted as three correction operations, and a weight may be given at the counting stage. Regardless of whether the number of operations is different or not, if the fluctuation range of the importance level Xs can be changed for each specific type of operation described above, the same effect as in the present embodiment can be obtained.
[0141]
[Fourth Embodiment]
In the first to third embodiments, regardless of whether the operation target is the entire information D or not, the display time and the number of operations are counted for each information D and used to calculate the importance of the information D. The case where the weighting coefficient P is adjusted has been described. On the other hand, in the present embodiment, when the operation target is a part of the information D, a case where the weighting coefficient P related to the part is adjusted will be described with reference to FIGS. Note that various operations can be cited as operations for which a part of the information D is to be operated, but in the following, partial display will be described as an example.
[0142]
That is, in S61 shown in FIG. 14, every time the information D is displayed on the screen, the display analysis unit 13a displays which part A of the information D is displayed based on, for example, a notification from the information control unit 15. And notifies the weighting coefficient processing unit 14a. On the other hand, in S62, the weight coefficient processing unit 14a requests the information analysis unit 13c to extract the keywords included in the portion A as shown in FIG. Furthermore, in S63, the weight coefficient processing unit 14a counts the number of operations for each keyword K and adjusts the keyword weight coefficient KP according to the number of operations, for example, so that the keyword K is included in the portion A. The keyword weighting coefficient KP of the keyword K is adjusted so that the importance level Xs is larger than the case where it is not.
[0143]
Note that the adjustment method of the keyword weighting coefficient KP may be adjusted without distinguishing various operations, as in the second or third embodiment, or may be weighted for each type of operation. In addition, in the case of an operation in which the user is assumed to not need the operation target, such as deletion of the operation target, the keyword weighting coefficient KP is adjusted so that the importance level Xs of the keyword K decreases.
[0144]
In any case, when a part of the information D is operated, the keyword weight coefficient KP of the keyword K can be individually adjusted depending on whether or not each keyword K in the information D is included in the operation target. . Therefore, the information management apparatus 2 can calculate the importance level Xs that is closer to the user's sense.
[0145]
[Fifth Embodiment]
In the fourth embodiment, the case where the keyword weight coefficient KP is adjusted depending on whether or not the information D is included in the operation target has been described. However, the keyword K is not included only in the information D. It is also included in character strings entered by the user, such as search character strings. In the present embodiment, adjustment of the keyword weighting coefficient KP according to the input character string will be described with reference to FIG.
[0146]
That is, in S71, for example, when the user inputs a character string for search or correction of information D, the input control unit 12b of the information management device 2 notifies the information analysis unit 13c of the input character string. To do. Further, in S72, the information analysis unit 13c extracts the keyword K included in the input character string.
[0147]
On the other hand, in S73, the information control unit 15 identifies the use of the input character string by, for example, investigating the status (mode) of the information management device 2 at the time of input, and notifies the weighting factor processing unit 14a. . Further, the weight coefficient processing unit 14a adjusts the keyword weight coefficient KP of each keyword K according to the situation (S74).
[0148]
For example, when the information management apparatus 2 is in a situation where a file F is newly created, the weight coefficient processing unit 14a sets the ratio of increasing the keyword weight coefficient KP to 1. On the other hand, when the information management apparatus 2 is in a state of updating the information D, the weighting factor processing unit 14a sets the ratio of increasing the keyword weighting factor KP to 1.5. In the situation where information D is searched, the keyword weight coefficient KP increases at a rate of 2.
[0149]
According to the above configuration, the keyword weight coefficient KP of the keyword K included in the character string input by the user is larger than that in the case where the keyword K is not included in the input character string. Furthermore, even if it is included in the input character string, the keyword weight coefficient KP of the keyword K increases in the order of new creation, update, and search.
[0150]
Generally, when a user inputs a character string, the user himself / herself inputs a character string regarded as important by the user. Therefore, by increasing the importance of the keyword K included in the user's input character string, the information management apparatus 2 can calculate the importance Xs close to the user's sense.
[0151]
Furthermore, the length of the character string is often shortened in the order of new creation, update, and search. In particular, at the time of search, only the keyword K that is regarded as important by the user is often input, and at the time of new creation, not only the keyword K that is emphasized but also other keywords K are input. Therefore, as described above, by adjusting the keyword weighting coefficient KP according to the use of the character string, the information management apparatus 2 can further calculate the importance level Xs that is close to the user's sense.
[0152]
[Sixth Embodiment]
By the way, in the first to fifth embodiments, for example, the weighting coefficient is determined according to all the operation situations after the information D (file F) is generated, such as the total display time T and the total number of operations m (d). The method for adjusting P (first method) has been described. According to this method, when responding to the number of operations m, the information X having a larger number of operations m increases the importance level Xs. Therefore, the information management apparatus 2 has a different number of operations m as shown in FIG. Different degrees of importance Xs can be presented for the information D.
[0153]
However, in this first method, for example, as shown in FIG. 18, a file F created one year ago and operated n times at that time._A Information D stored in_A Importance Xs_A Is the file F recently created and manipulated n times_B Information D stored in_B Importance Xs_B Will be the same.
[0154]
Here, in general, information D that has been frequently manipulated recently_B Is information D that has been frequently manipulated once_A In many cases, the current importance level Xs is higher. Therefore, when the weighting factor P is adjusted by the first method, both the above-mentioned importance levels Xs_A ・ Xs_B The value of the_B May be difficult to discover.
[0155]
In contrast, as a second method, the weight coefficient processing unit 14a according to the present embodiment divides the total number of operations m by the elapsed time R from the creation of the file F to the present (m / R), the weighting factor P is changed. The elapsed time R can be calculated from the creation date and time stored as an attribute of the information D.
[0156]
In the present embodiment, the weight coefficient processing unit 14a adjusts the weight coefficient P according to m / R instead of the number of operations m. Therefore, as the information D has a longer elapsed time R, the number of operations m necessary to maintain the weighting coefficient P increases, and the importance level Xs relatively decreases. As a result, the information management apparatus 2 can calculate the importance level Xs that is closer to the user's sense at the present time.
[0157]
[Seventh Embodiment]
In the first to sixth embodiments, the total display time T and the number of operations m stored in the history storage unit 11c have been described as being updated at the time of operation. However, the total display time T and the number of operations are not limited. The method to obtain is not limited to this.
[0158]
In the present embodiment, a case will be described in which history information H including an operation time is stored in the history storage unit 11c and the importance level Xs is calculated based on the history information H during operation. In the following, for convenience of explanation, the case where the history information H is stored in the second embodiment will be described as an example.
[0159]
That is, as shown in FIG. 19, when the user operates the information D in S81, the information control unit 15 stores the operation history information H in S82. The history information H includes the operation time and information necessary for calculating the importance level Xs later. For example, when the importance level Xs is calculated for the information D based on the number of operations, the history information H includes the date and time of the operation and the information D to be operated.
[0160]
Furthermore, when calculating the importance level Xs, the weighting factor processing unit 14a adjusts each weighting factor P based on the history information H of each information D in S83 to calculate the importance level Xs.
[0161]
Here, in the present embodiment, the weighting coefficient processing unit 14a receives each information D from the history information H stored in the history storage unit 11c._A If the history information H related to each is extracted, the number of operations m of each information D can be calculated. Therefore, the weighting coefficient processing unit 14a performs the weighting coefficient of each information D according to the number of operations m or the value obtained by dividing the number of operations m by the elapsed time R, as in the first method and the second method. P can be adjusted.
[0162]
Furthermore, in the present embodiment, since the history information H is stored, in addition to the first method and the second method, a third method for weighting according to the operation time can be selected.
[0163]
For example, when the rate of increasing the weighting coefficient P is 1 when used once a month recently, 0.9 is used when it is used once in the period from the past one month to two months ago. The weighting factor P is adjusted by assigning a weight so that the weighting becomes smaller as the operation time is away from the current time, such that the period from 2 months ago to 3 months ago is 0.8. As a result, as shown in FIG. 20, even when the elapsed time R and the number of operations m are the same, the importance level Xs of the information D that has been operated more recently can be relatively increased. As a result, the information management apparatus 2 can calculate the importance level Xs further adapted to the user's feeling.
[0164]
Here, the case where weighting is performed according to the difference from the current time has been described above, but the present invention is not limited to this. If weighting is applied according to the difference from an arbitrary time point, the importance level Xs suitable for the sense of the user at that time point can be calculated. In general, the importance Xu felt by the user is not always consistent and often changes with the passage of time. Therefore, the user may search for the information D based on the information D that is considered important at a certain time. In this case, the information management apparatus 2 is required to calculate the importance level Xs that is close to the user's feeling at a certain time. In the third method, by calculating the history information H, the importance level Xs at an arbitrary time point can be calculated. Furthermore, since the history storage unit 11c stores the history information H, any method of the first method to the third method can be selected according to the user's request. Therefore, it is possible to greatly reduce the labor for the user to find the desired information D.
[0165]
In the above description, the history information H has been described by taking as an example the case where information necessary for calculating the importance in the second embodiment is stored. However, the importance in the first to fifth embodiments is described. If information necessary for calculation is stored, the same effect can be obtained regardless of which information is applied.
[0166]
In particular, when applied to the third embodiment, a specific type of operation can be specified at the time of importance calculation, and the weighting between various operations can be changed. For example, if the weight of the printing operation is increased, the importance level Xs of the information D that has been subjected to the communication operation can be increased. Therefore, the method when the information management device 2 calculates the importance level Xs can be changed more flexibly, and the time and effort required for the user to find the desired information D can be greatly reduced.
[0167]
By the way, storing the history information H requires more storage capacity than storing the total display time T and the number of operations m (d). However, since the storage capacity required for storing the history information H is often much smaller than the storage capacity required for storing the information D, the storage capacity of the information management apparatus 2 as a whole does not increase much.
[0168]
Note that the adjustment method of the weighting coefficient P described in each of the first to seventh embodiments can be used in any combination. In this case, since the weighting coefficient P can be adjusted according to various operations, the information management apparatus 2 can calculate the importance level Xs that is closer to the user's sense. In particular, for example, if the weighting factor P is adjusted based on different operations such as the presence / absence of redisplay and the presence / absence of external output, the weighting factor P can be adjusted widely according to general operations. Can calculate the importance Xs more accurately.
[0169]
In each of the above embodiments, the case where the importance Xs of the information D increases as the weighting factor P increases has been described. However, the present invention is not limited to this. For example, even when the importance level Xs of the information D is calculated by other methods, such as when the weighting factor P increases or the importance level Xs of the information D decreases, the importance level Xs of the above embodiments and the information D is If the weighting coefficient P can be adjusted so as to change similarly, the same effect can be obtained.
[0170]
Furthermore, in each of the above-described embodiments, the case where the weighting coefficient P used for calculating the importance of the information D is adjusted when an operation related to the information D is performed has been described. The weighting factor P that is not used for calculating the importance of the information D may be adjusted. The same effect can be obtained if the magnitude of the weighting factor P used for the importance calculation and the magnitude of the remaining weighting factor P can be changed relatively.
[0171]
In addition, the recording medium according to each of the above embodiments includes a weighting factor created according to each information, Based on a weighting factor related to information, an importance calculation step for calculating the importance of the information, and a weighting factor adjustment for adjusting a weighting factor used in the importance calculation step according to an operation related to information A program for executing the process is recorded.
