Description

表１を参照して、各店舗の広告情報１００には、店コードの欄と、有効日付の欄と、商品分類の欄と、広告の欄と、通常の欄とがある。店コードの欄には、各店舗に一意に付与された識別番号が記録される。有効日付の欄には、広告が有効な日付が記録される。商品分類の欄には、各商品を特定するための分類番号が記録される。商品分類の欄にはさらに、大分類の欄と、中分類の欄と、小分類の欄とがある。大分類の欄には大分類番号が記録され、中分類の欄には中分類番号が記録され、小分類の欄には小分類番号及び商品名が記録される。広告の欄には、広告の内容が記録される。広告の欄にはさらに、広告表示数量の欄と、広告表示価格の欄と、広告基準価格の欄とがある。広告表示数量の欄には、広告商品の販売単位（広告表示数量）が記録される。広告表示価格の欄には、広告商品の販売価格（広告表示価格）が記録される。広告基準価格の欄には、広告商品の基準単位当たりの価格（広告基準価格）が記録される。
【００４５】
表１の例では、玉ねぎをＡ店は３個３９８円で販売しているのに対し、Ｂ店は１個８５円で販売している。したがって、広告表示価格を単純に比較しても、どちらの店舗の玉ねぎが安いのかを判断することはできない。そのため、価格を比較するときの商品の数又は量を決めておく必要がある。この商品の数又は量が基準単位であり、基準単位当たりの価格が基準価格である。広告基準価格は次の式（１）で算出される。
【００４６】
広告基準価格＝広告表示価格／広告表示数量×基準単位 （１）
【００４７】
「玉ねぎ」の基準単位は「１個」であるから、Ａ店の広告基準価格は「１３２．７円」であるのに対し、Ｂ店の広告基準価格は「８５．０円」である。よって、Ｂ店の玉ねぎの方が安い。なお、各商品の基準単位は商品マスタ７００に登録されているが、これについては後述する。
【００４８】
また、通常の欄には、通常時における商品の販売内容が記録される。通常の欄にはさらに、通常表示数量の欄と、通常表示価格の欄と、通常基準価格の欄とがある。通常表示数量の欄には、通常時における商品の販売単位（通常表示数量）が記録される。通常表示価格の欄には、通常時における商品の販売価格（通常表示価格）が記録される。通常基準価格の欄には、通常時における商品の基準単位当たりの価格（通常基準価格）が記録される。通常基準価格は次の式（２）で算出される。
【００４９】
通常基準価格＝通常表示価格／通常表示数量×基準単位 （２）
【００５０】
３−２．分類マスタの構成
次の表２は、分類マスタ６００に登録されるテーブルの一例を示す。
【００５１】
【表２】

表２を参照して、分類マスタ６００は、広告データベース２０３に登録される商品分類の体系を表したテーブルを有する。このテーブルには、大分類の欄と、中分類の欄とがある。大分類の欄には、大分類識別子及び大分類名が記録される。表２の例では、大分類識別子「００１」は大分類名「鮮魚」を示す。また、大分類識別子「００３」は大分類名「青果」を示す。中分類の欄には、大分類をさらに細分化した中分類、具体的には中分類識別子及び中分類名が記録される。たとえば大分類識別子「００３」の大分類名「青果」に対応する中分類の欄には、中分類識別子「００１」の中分類名「レタス」と、中分類識別子「００２」の中分類名「大根」と、中分類識別子「００３」の中分類名「玉ねぎ」とが記録される。
【００５２】
３−３．商品マスタの構成
次の表３は、商品マスタ７００に登録されるテーブルの一例を示す。
【００５３】
【表３】

表３を参照して、商品マスタ７００は、広告データベース２０３に登録される商品の名称を登録するためのテーブルを有する。このテーブルには、大分類の欄と、中分類の欄と、小分類の欄と、商品名の欄と、基準単位の欄とがある。大分類の欄には大分類識別子が記録され、中分類の欄には中分類識別子が記録される。小分類の欄には、中分類をさらに細分化した小分類、具体的には小分類識別子が記録される。商品名の欄には小分類識別子に対応して商品名が記録される。表２の例では、大分類識別子「００４（＝日用品）」の中分類識別子「００１（＝トイレットペーパー）」に対応して、小分類識別子「０００」及び商品名「トイレットペーパー」、小分類識別子「００１」及び商品名「ＴＡ」、並びに小分類識別子「００３」及び商品名「ＴＢ」が記録される。基準単位の欄には、基準価格を算定するための基準単位が記録される。
【００５４】
３−４．価格マスタの構成
次の表４は、価格マスタ８００に登録されるテーブルの一例である。
【００５５】
【表４】

表４を参照して、価格マスタ８００は、所定地域ごとに商品の底値及び安値を登録するためのテーブルを有する。このテーブルには、地域コードの欄と、商品分類の欄と、底値の欄と、安値基準価格の欄とがある。地域コードの欄には、所定地域ごとに予め定められた地域コードが記録される。分類の欄には、大分類の欄と、中分類の欄と、小分類の欄とがある。これらの欄には、前述した大分類識別子、中分類識別子、及び小分類識別子が記録される。底値の欄には、底値表示数量の欄と、底値表示価格の欄と、底値基準価格の欄と、参照日付の欄とがある。底値表示数量の欄には商品が底値で販売されたときの一販売当たりの商品の数量が記録され、底値表示価格の欄には底値で販売されたときの一販売当たりの商品の価格が記録され、底値基準価格の欄には底値で販売された商品の基準価格が記録される。表４の例では、商品「サンマ」（大分類「００１」、中分類「００１」、小分類「００１」）は、３尾で３００円が底値である。よって、底値表示数量は「３尾」であり、底値表示価格は「３００円」である。また、表２に示した商品マスタ７００より商品「サンマ」の基準単位は「１尾」であるから、底値基準価格は「１００円」である。
【００５６】
参照日付の欄には、広告基準価格が底値基準価格よりも安い場合、又は広告基準価格が底値基準価格以上であってもその差額が所定範囲（本例では底値基準価格の１０％）内の場合、その広告の有効日付が記録される。ただし、その差額が所定範囲外の場合、参照日付は以前のまま維持される。すなわち、参照日付は底値基準価格が更新されるか、更新されなくても広告基準価格が現在登録されている底値基準価格に近い場合、参照日付は更新される。したがって、底値基準価格が異常に安い広告基準価格で更新されたとすると、参照日付は長期間更新されなくなる。よって、参照日付が長期間更新されない場合は登録されている底値基準価格をクリアするようにすれば、底値基準価格が異常に安い広告基準価格で更新され、それ以降ずっと更新されなくなるのを防止することができる。
【００５７】
また、安値基準価格の欄には、複数の店舗の中で最も安い商品の広告基準価格が記録される。
【００５８】
３−５．地域マスタの構成
次の表５は、地域マスタ９００に登録されるテーブルの一例である。
【００５９】
【表５】

表５を参照して、地域マスタ９００は、各店舗の所在地域を特定するためのテーブルを有する。このテーブルには、地域コードの欄と、店コードの欄とがある。店コードの欄には、１つの地域コードに対応して１又は２以上の店コードが記録される。表５の例では、地域コード「００１」に対応して２つの店コード「００１」及び「００２」が記録されている。すなわち、店コード「００１」は地域コード「００１」だけでなく地域コード「００２」にも対応して記録されている。「００１」の店舗は実際には「００２」の地域に存在する場合でも「００１」の地域が「００２」の地域と隣接しているときは、このような態様で店コードを記録することにより「００１」の店舗の広告を「００２」の地域だけでなく「００１」の地域にも配信できるようにする。
【００６０】
４．広告配信システムの動作
次に、本システムの動作を説明する。本システムは、主として広告配信機能及び広告表示機能という２つの動作を行う。
【００６１】
４−１．広告配信機能
広告配信機能による動作は、広告登録処理、価格マスタ更新処理、配信一時ファイル作成処理、配信処理の順に行われる。以下、各処理を説明する。
【００６２】
４−１−１．広告登録処理
まず図１及び図２を参照して、広告の登録処理を説明する。この処理は、売り主が広告登録端末３０を用いて広告配信装置２０の広告データベース２０３に所望の広告を登録するものである。以下、この処理の詳細を説明する。
【００６３】
まず、広告登録端末３０は売り主の操作に応じて広告の有効日付を入力する（Ｓ１）。
【００６４】
続いて、広告登録端末３０は分類マスタ６００を照会し、全ての大分類を取得する（Ｓ２）。広告登録端末３０は、取得した大分類をディスプレイ（図示せず）上に表示する。広告登録端末３０は、表示された大分類の中から売り主の操作に応じて所望の１つを選択する（Ｓ３）。広告登録端末３０は分類マスタ６００を検索し、選択された大分類に属する全ての中分類を取得する（Ｓ４）。広告登録端末３０は、取得した中分類をディスプレイ上に表示する。
【００６５】
表示された中分類の中に広告を登録しようとする中分類がある場合、売り主はその中分類を選択するが、ない場合、所望の中分類を入力する。中分類がある場合、広告登録端末３０は分類マスタ６００の中から売り主の操作に応じて所望の中分類を選択し、ステップＳ６に進む（Ｓ５）。一方、中分類がなく、入力する場合、広告登録端末３０はステップＳ８に進む（Ｓ５）。
【００６６】
分類マスタ６００の中から中分類を選択した場合、広告登録端末３０は商品マスタ７００を検索し、選択された中分類に属する全ての小分類を取得する（Ｓ６）。広告登録端末３０は、取得した小分類をディスプレイ上に表示する。広告登録端末３０は、表示された小分類の中から売り主の操作に応じて所望の１つを選択する（Ｓ７）。一方、売り主が所望の中分類を入力する場合、広告登録端末２０は中分類識別子及び小分類識別子をともに「９９９」に設定し（Ｓ８）、売り主の操作に応じて所望の小分類名を入力する（Ｓ９）。
【００６７】
続いて、広告登録端末３０は売り主の操作に応じて広告内容を入力する（Ｓ１０）。具体的には、広告商品の販売単位である広告表示数量と、広告商品の販売価格である広告表示価格とを入力する。広告登録端末３０は、入力された広告表示数量及び広告表示価格並びに商品マスタ７００に登録されている基準単位に基づき、前述した式（１）により広告基準価格を算出する（Ｓ１１）。
【００６８】
続いて、広告登録端末３０はこれらの広告情報を広告配信装置２０に送信し、広告データベース２０３に登録する（Ｓ１２）。具体的には、入力された広告表示数量を広告表示数量の欄に記録し、入力された広告表示価格を広告表示価格の欄に記録し、算出された広告基準価格を広告基準価格の欄に記録する。
【００６９】
全ての広告を登録し終えた場合、広告登録端末３０は上述した広告登録処理を終了するが、未だ終えていない場合はステップＳ３に戻って広告登録処理を繰り返す。
【００７０】
なお、図２のフロー図には示されていないが、ステップＳ１０で広告内容を入力するとき、通常時における商品の販売内容が未だ広告データベース２０３に登録されていない場合はその内容も併せて入力する。具体的には、通常時における商品の販売単位である通常表示数量と、通常時における商品の販売価格である通常表示価格とを入力する。広告登録端末３０は、ステップＳ１１で広告基準価格を算出するとき、入力された通常表示数量及び通常表示価格並びに商品マスタ７００に登録されている基準単位に基づき、前述した式（２）により通常基準価格も併せて算出する。広告登録端末３０は、ステップＳ１２で広告情報を登録するとき、通常時における商品の販売情報も併せて登録する。具体的には、入力された通常表示数量を通常表示数量の欄に記録し、入力された通常表示価格を広告表示価格の欄に記録し、算出された通常基準価格を通常基準価格の欄に記録する。
【００７１】
また、ステップＳ１１で広告基準価格や通常基準価格を算出するときに商品マスタ７００に登録されている基準単位を用いているが、商品マスタ７００に登録されていない商品については基準単位も登録されていない。そこで、商品マスタ７００に登録されていない商品の広告基準価格や通常基準価格を算出する場合には、基準単位を「１」に設定する。表１の例ではＡ店の広告情報１００に「歯ブラシ」が登録されているが、「歯ブラシ」は商品マスタ７００に登録されていない。そのため、基準単位を「１」に設定し、広告基準価格「１３２．０円」（＝１３２円／１本×１本）や通常基準価格「１５０．０円」（＝１５０円／１本×１本）を算出している。
【００７２】
４−１−２．価格マスタ更新処理
次に図１及び図３を参照して、価格マスタ８００の更新処理を説明する。上述した広告登録処理が終了すると、広告配信装置２０は価格マスタ８００の更新処理を開始する。この処理は、広告データベース２０３に登録された広告情報１００に基づき、価格マスタ８００に登録されている底値及び安値を更新するものである。以下、この処理の詳細を説明する。
【００７３】
まず広告配信装置２０において、データ処理部２０４は広告データベース２０３の中からある１つの商品に関する広告情報１００を読み込む（Ｓ１４）。
【００７４】
続いて、データ処理部２０４は共通データベース２０２の地域マスタ９００を検索し、読み込んだ広告情報１００の店コードに対応する地域コードを読み込む（Ｓ１５）。
【００７５】
続いて、データ処理部２０４は価格マスタ８００を検索し、読み込んだ地域コードと同じ地域コードを有しかつ読み込んだ広告情報１００の商品分類と同じ商品分類を有する商品を特定する（Ｓ１６）。
【００７６】
続いて、データ処理部２０４は、ステップＳ１４で読み込んだ広告情報１００の広告基準価格をステップＳ１６で特定した商品の底値基準価格と比較する（Ｓ１７）。比較の結果、広告基準価格が底値基準価格よりも安い場合、データ処理部２０４は広告基準価格で底値基準価格を更新する（Ｓ１８）。この場合、データ処理部２０４は読み込んだ広告情報１００の広告表示価格及び広告表示数量で価格マスタ８００の底値表示価格及び底値表示数量もそれぞれ併せて更新する（Ｓ１８）。その後、データ処理部２０４は読み込んだ広告情報１００の有効日付で価格マスタ８００の参照日付を更新する（Ｓ２０）。
【００７７】
一方、広告基準価格が底値基準価格よりも安くない高い場合、データ処理部２０４は広告基準価格が次の式（３）を満たすか否かを判断する（Ｓ１９）。
【００７８】
広告基準価格≦底値基準価格＋１０％ （３）
【００７９】
広告基準価格が式（３）を満たす場合、データ処理部２０４は上記と同様に広告情報１００の有効日付で価格マスタ８００の参照日付を更新する（Ｓ２０）。一方、広告基準価格が式（３）を満たさない場合、データ処理部２０４は参照日付を更新せず、次のステップＳ２１に進む。底値基準価格の所定割合は本システムで予め設定される。本例では所定割合を底値基準価格の１０％に設定している。
【００８０】
次に、データ処理部２０４は、ステップＳ１４で読み込んだ広告情報１００の広告基準価格をステップＳ１６で特定した商品の安値基準価格と比較する（Ｓ２１）。比較の結果、広告基準価格が安値基準価格よりも安い場合、データ処理部２０４は広告基準価格で安値基準価格を更新する（Ｓ２２）。一方、広告基準価格が安値基準価格よりも安くない場合、データ処理部２０４は安値基準価格を変更せず、次のステップＳ２３に進む。
【００８１】
最後に、データ処理部２０４は広告データベース２０３に登録されている全ての商品に関する広告情報１００について価格マスタ更新処理を行ったか否かを判断する（Ｓ２３）。全ての商品に関する広告情報１００について価格マスタ更新処理を行った場合、データ処理部２０４は価格マスタ更新処理を終了するが、行っていない場合はステップＳ１４に戻って価格マスタ更新処理を繰り返す。
【００８２】
４−１−３．配信一時ファイル作成処理
次に図１、図４及び図５を参照して、配信一時ファイル３００の作成処理を説明する。上述した価格マスタ更新処理が終了すると、広告配信装置２０は配信一時ファイル３００の作成処理を開始する。この処理は、広告データベース２０３に登録されている広告情報１００及び価格マスタ８００に登録されている底値及び安値に基づいて、携帯電話機１０への配信データを作成するのに必要な配信一時ファイル３００を作成するものである。配信一時ファイル３００の作成処理を説明する前に、まず配信一時ファイル３００の構成を説明する。
【００８３】
次の表６は、配信一時ファイル３００の一例である。
【００８４】
【表６】

表６を参照して、配信一時ファイル３００には、携帯電話機１０に配信すべき配信データの作成に必要な情報が記録される。配信一時ファイル３００には具体的には、有効日付の欄と、地域コードの欄と、店コードの欄と、商品分類（大分類、中分類、小分類）の欄と、基準単位の欄と、広告（広告表示数量、広告表示価格、広告基準価格）の欄と、安値フラグの欄と、底値基準価格の欄と、通常基準価格の欄とがある。安値フラグの欄には、広告基準価格が安値か否かを識別するためのフラグが記録される。配信一時ファイル３００の各欄には、後述の一時ファイル作成処理により所定の情報が記録される。以下、配信一時ファイル作成処理の詳細を説明する。
【００８５】
まず広告配信装置２０において、データ処理部２０４は広告データベース２０３の中からある１つの商品に関する広告情報１００（店コード、有効日付、大分類識別子、中分類識別子、小分類識別子、広告表示数量、広告表示価格、広告基準価格、通常表示数量、通常表示価格、通常基準価格）を読み込む（Ｓ２４）。
【００８６】
続いて、データ処理部２０４は共通データベース２０２の地域マスタ９００を検索し、ステップＳ２４で読み込んだ店コードに対応する地域コードを付加する（Ｓ２５）。
【００８７】
続いて、データ処理部２０４は分類マスタ６００を検索し、ステップＳ２４で読み込んだ大分類識別子及び中分類識別子にそれぞれ対応する大分類名及び中分類名を付加する（Ｓ２６）。
【００８８】
続いて、データ処理部２０４は商品マスタ７００を検索し、ステップＳ２４で読み込んだ小分類識別子に対応する基準単位を付加する（Ｓ２７）。
【００８９】
続いて、データ処理部２０４は価格マスタ８００を検索し、ステップＳ２５で読み込んだ地域コード及びステップＳ２４で読み込んだ商品分類（大分類識別子、中分類識別子、小分類識別子）に基づいて当該商品の安値基準価格及び底値基準価格を抽出する（Ｓ２８）。
【００９０】
続いて、データ処理部２０４はステップＳ２４で読み込んだ広告基準価格をステップＳ２８で抽出した安値基準価格と比較する（Ｓ２９）。比較の結果、広告基準価格が安値基準価格以下の場合、安値フラグを「１」にする（Ｓ３０）。一方、広告基準価格が安値基準価格よりも高い場合、安値フラグを「０」にする（Ｓ３１）。
【００９１】
続いて、データ処理部２０４はステップＳ２８で抽出した底値基準価格を付加する（Ｓ３２）。
【００９２】
続いて、データ処理部２０４はステップＳ２４〜Ｓ２８，Ｓ３０〜Ｓ３３で得た広告情報、地域コード、大分類名及び中分類名、基準単位、安値フラグ、及び底値基準価格を配信一時ファイル３００に登録する（Ｓ３３）。
【００９３】
最後に、データ処理部２０４は広告データベース２０３に登録されている全ての商品に関する広告情報１００について配信一時ファイル作成処理を行ったか否かを判断する（Ｓ３４）。全ての商品に関する広告情報１００について配信一時ファイル作成処理を行った場合、データ処理部２０４は配信一時ファイル作成処理を終了するが、行っていない場合はステップＳ２４に戻って配信一時ファイル作成処理を繰り返す。
【００９４】
４−１−４．配信処理
次に図１、図５及び図６を参照して、広告の配信処理を説明する。上述した配信一時ファイル作成処理が終了すると、広告の配信準備が整う。広告配信装置２０は携帯電話機１０からの広告配信要求に応じて広告の配信処理を開始する。この処理は、作成された配信一時ファイルに基づき、携帯電話機１０への配信データを作成するものである。ただし、全ての買い主に同じ配信データを配信するのではなく、買い主ごとにカスタマイズした配信データを配信する。配信データをカスタマイズするために、買い主は必要な情報を携帯電話機１０に登録する。配信処理の詳細を説明する前に、このカスタマイズ情報の登録方法を説明する。
【００９５】
まず、携帯電話機１０は買い主の操作に応じて買物メモ１５２を登録する（Ｓ３８）。買物メモ１５２は、買い主が購入を予定している商品を登録しておくためのものである。買物メモ１５２の登録方法は２通りある。１つは分類マスタ６００に登録されている商品の中から１つを選択する方法である。もう１つは任意の商品を手動で入力する方法である。
【００９６】
最初に分類マスタ６００の中から商品を選択する方法を説明する。図７を参照して、携帯電話機１０はＥＥＰＲＯＭ１０３には買物メモ１５２を記憶している。買物メモ１５２には、利用者ＩＤの欄、商品分類（大分類及び中分類）の欄、買値の欄、及び登録日の欄がある。買値の欄にはさらに、数量の欄及び価格の欄がある。
【００９７】
買い主が買物メモ１５２を登録する場合、携帯電話機１０は表示部１０７に買物メモの画面１１１を表示する。買い主は購入予定商品を登録するとき、買物メモの画面１１１上の「２．追加」を選択する。これにより、画面１１１は画面１１２に切り替わる。買い主は画面１１２上の「１．分類マスタより選択」を選択する。その結果、携帯電話機１０は無線基地局４０を介して広告配信装置２０に接続され、分類マスタ６００から大分類及び中分類を取得する。これにより、画面１１２は画面１１３に切り替わる。この画面１１３上には取得した複数の大分類が表示される。買い主は表示された大分類の中から購入予定商品が属する大分類を１つ選択する。図７の例では、買い主は「４．日用品」を選択している。買い主が大分類を選択すると、図示されていないが、携帯電話機１０は選択した大分類に属する中分類を表示する。買い主は購入予定商品が属する中分類を選択する。選択された大分類及び中分類は、買物メモ１５２の商品分類の欄に記録される。
【００９８】
続いて、買い主は選択した中分類に属する商品の買値情報を登録する。買値情報には、買値数量及び買値価格が含まれる。買値数量は買い主の希望購入数量であり、買値価格は買い主の希望購入価格である。希望購入数量は買物メモ１５２の数量の欄に記録され、希望購入価格は買物メモ１５２の価格の欄に記録される。
【００９９】
次に、任意の商品を手動で入力する方法を説明する。分類マスタ６００に購入予定商品が属する分類がない場合、図８を参照して、買い主は買物メモの画面１１２において「２．手入力」を選択する。これにより、画面１１２は画面１１４に切り替わる。この画面１１４上には、購入予定商品の名称を入力するための商品名入力部１１６と、その商品の希望購入数量を入力するための数量入力部１１７と、その商品の単位を入力するための単位入力部１１８が表示される。買い主は商品名を商品名入力部１１６に入力し、数量を数量入力部１１７に入力し、単位を単位入力部１１８に入力する。入力された商品名は買物メモ１５２の中分類の欄に記録され、入力された数量及び単位は買物メモ１５２の数量の欄に記録される。このように任意の商品を手動で入力した場合、買物メモ１５２の大分類及び中分類識の欄にはいずれも識別子「９９９」が記録される。
【０１００】
なお、買物メモ１５２の利用者ＩＤの欄には、図５に示した利用者情報１６０の利用者ＩＤが記録される。また、登録日の欄には、買物メモ１５２を登録又は更新した日付が記録される。
【０１０１】
買物メモ１５２を登録した後、携帯電話機１０は買い主の操作に応じて価格差率１５４を登録する（Ｓ３９）。価格差率は、広告基準価格が底値基準価格よりも高い場合でも買い主がほぼ底値とみる底値差率を登録したり、買い主が買い得とみる割引率を登録したりするためのものである。
【０１０２】
図９を参照して、買い主が価格差率を登録する場合、携帯電話機１０は表示部１０７に価格差率の画面１１９を表示する。買い主が画面１１９上の「２．追加」を選択すると、携帯電話機１０は無線基地局４０を介して広告配信装置２０に接続され、分類マスタ６００を参照し、全ての大分類を取得する。これにより画面１１９は画面１２０に切り替わり、携帯電話機１０は取得した大分類を画面１２０上に表示する。買い主は表示された大分類の中から価格差率を設定しようとする大分類を１つ選択する。図９の例では、買い主は「３．青果」を選択している。大分類を選択すると、画面１２０は画面１２１に切り替わる。画面１２１には、底値差率を入力するための底値差率入力部１２２と、割引率を入力するための割引率入力部１２３とが表示される。買い主は所望の底値差率を底値差率入力部１２２に入力し、所望の割引率を割引率入力部１２３に入力する。図９の例では、「３％」の底値差率が入力され、「１０％」の割引率が入力されている。
【０１０３】
上述したカスタマイズ情報（買物メモ及び価格差率）の登録後、買い主が携帯電話機１０を操作して広告の配信を要求すると、広告配信装置２０は広告の配信処理を開始する。以下、図１、図５及び図６を参照して、配信処理の詳細を説明する。
【０１０４】
携帯電話機１０は、上記で登録された買物メモ１５２（厳密にはその一部）及び価格差率１５４を利用者情報１６０とともに広告配信装置２０に送信し（Ｓ４０、図５中の▲１▼）、広告配信装置２０はこれを受信する（Ｓ４１）。このとき、買物メモ１５２の中分類識別子は送信されるが、中分類名は送信されない。中分類名は分類マスタ６００に登録されているからである。また、買物メモ１５２に手動で入力された商品の情報（図５の例では「サラダ油」に関する情報）も送信されない。手動で入力された商品には正規の分類コードがなく、広告データベース２０３や価格マスタ８００を参照できないからである。ただし、価格差率１５４及び利用者情報１６０の内容はそのまま送信される。その結果、広告配信装置２０は図３に示すような買物メモ１５５（買物メモ１５２の一部）を取得する。なお、利用者情報１６０には、利用者ＩＤ、メールアドレス及び地域コードが含まれる。これらは予め登録されている。
【０１０５】
広告配信装置２０は買物メモ１５５などを受信した後、その受信した買物メモ１５５及び上記で作成した配信一時ファイル３００に基づいて配信データ４００を作成し、携帯電話機１０に送信する（図５中の▲２▼）。
【０１０６】
次の表７は、配信データ４００の構成を示す。
【０１０７】
【表７】

表７を参照して、配信データ４００には、有効日付、店コード、商品分類（大分類、中分類、小分類）、広告（広告表示数量及び広告表示価格）、フラグ（底値フラグ、安値フラグ、割引フラグ、買物メモフラグ、Ｍｕｓｔ−Ｂｕｙフラグ）が登録される。底値フラグは、当該商品の広告価格が底値以下又はほぼ底値か否かを識別するためのフラグである。割引フラグは、当該商品の広告価格が通常よりも安いか否かを識別するためのフラグである。買物メモフラグは、当該商品が買物メモ１５５に登録されているか否か、登録されている場合は当該商品の広告価格が希望購入価格以下か否かを識別するためのフラグである。Ｍｕｓｔ−Ｂｕｙフラグは、当該商品が買い得又は購入予定であるか否かを識別するためのフラグである。
【０１０８】
次に、この配信データ４００の作成方法の詳細を説明する。
【０１０９】
広告配信装置２０において、データ処理部２０４は上記で作成した配信一時ファイル３００から必要な情報を読み込む（Ｓ４２）。具体的には、利用者情報１６０の地域コードと同じ地域コードを有する商品について、有効日付、店コード、商品分類、広告表示数量、広告表示価格、及び安値フラグを読み込む。
【０１１０】
続いて、データ処理部２０４は買物メモフラグを設定する（Ｓ４３〜Ｓ４９）。具体的には、データ処理部２０４は買物メモ１５５を検索し（Ｓ４３）、商品分類が買物メモ１５５に登録されているか否かを判断する（Ｓ４４）。判断の結果、商品分類が買物メモ１５５に登録されている場合、データ処理部２０４は次の式（４）により買値基準価格を算出する（Ｓ４５）。
【０１１１】
買値基準価格＝買値価格／買値数量×基準単位 （４）
【０１１２】
買値価格及び買値数量は買物メモ１５５から読み出され、基準単位は配信一時ファイル３００から読み出される。買値基準価格は、基準単位当たりの希望購入価格である。
【０１１３】
続いて、データ処理部２０４は広告基準価格を算出した買値基準価格と比較する（Ｓ４６）。比較の結果、広告基準価格が買値基準価格以下の場合、データ処理部２０４は買物メモフラグを「２」にする（Ｓ４７）。一方、広告基準価格が買値基準価格以下でない場合、データ処理部２０４は買物メモフラグを「１」にする（Ｓ４８）。
【０１１４】
一方、ステップＳ４４における判断の結果、商品分類が買物メモ１５５に登録されていない場合、データ処理部２０４は買物メモフラグを「０」にする（Ｓ４９）。
【０１１５】
ステップＳ４３〜Ｓ４９の結果、買い主が買物メモに登録した商品のうち、希望購入価格以下で広告されている商品については買物メモフラグが「２」になり、希望購入価格よりも高い価格で広告されている商品については買物メモフラグが「１」になる。買い主が買物メモに登録していない商品については買物メモフラグが「０」になる。
【０１１６】
続いて、データ処理部２０４は底値フラグを設定する（Ｓ５０〜Ｓ５４）。具体的には、データ処理部２０４は、広告基準価格を底値基準価格と比較する（Ｓ５０）。比較の結果、広告基準価格が底値基準価格以下の場合、データ処理部２０４は底値フラグを「１」にする（Ｓ５１）。一方、広告基準価格が底値基準価格以下でない場合、データ処理部２０４は広告基準価格が次の式（５）を満たすか否か判断する（Ｓ５２）。
【０１１７】
広告基準価格≦底値基準価格×（１＋底値差率） （５）
【０１１８】
広告基準価格及び底値基準価格は配信一時ファイル３００から読み出され、底値差率は価格差率１５４から読み出される。判断の結果、広告基準価格が式（５）を満たす場合、データ処理部２０４は底値フラグを「２」にする（Ｓ５３）。一方、広告基準価格が式（５）を満たさない場合、データ処理部２０４は底値フラグを「０」にする（Ｓ５４）。
【０１１９】
ステップＳ５０〜Ｓ５４の結果、底値以下の商品については底値フラグが「１」になる。また、底値以下でない商品であってもほぼ底値の商品については底値フラグが「２」になり、ほぼ底値でもない商品については底値フラグは「０」になる。
【０１２０】
続いて、データ処理部２０４は割引フラグを設定する（Ｓ５５〜Ｓ５７）。具体的には、データ処理部２０４は価格差率１５４の割引率が次の式（６）を満たすか否かを判断する（Ｓ５５）。
【０１２１】
割引率≦（通常基準価格−広告基準価格）／通常基準価格×１００ （６）
【０１２２】
判断の結果、割引率が式（６）を満たす場合、データ処理部２０４は割引フラグを「１」にする（Ｓ５６）。一方、割引率が式（６）を満たさない場合、データ処理部２０４は割引フラグを「０」にする（Ｓ５７）。
【０１２３】
ステップＳ５５〜Ｓ５７の結果、買い主の希望割引率以上に割引されている商品については割引フラグが「１」になり、それほど割引されていない商品については割引フラグが「０」になる。
【０１２４】
続いて、データ処理部２０４はＭｕｓｔ−Ｂｕｙフラグを設定する（Ｓ５８〜Ｓ６３）。具体的には、データ処理部２０４は、底値フラグが「１」又は「２」であるか否かを判断する（Ｓ５８）。判断の結果、底値フラグが「１」又は「２」の場合、データ処理部２０４はＭｕｓｔ−Ｂｕｙフラグを「Ｔｒｕｅ（真）」にする（Ｓ５９）。一方、底値フラグが「１」又は「２」でない場合、つまり「０」の場合、データ処理部２０４は安値フラグが「１」か否かを判断する（Ｓ６０）。判断の結果、安値フラグが「１」の場合、データ処理部２０４はＭｕｓｔ−Ｂｕｙフラグを「Ｔｒｕｅ」にする（Ｓ５９）。一方、安値フラグが「０」の場合、データ処理部２０４は割引フラグが「１」か否かを判断する（Ｓ６１）。判断の結果、割引フラグが「１」の場合、データ処理部２０４はＭｕｓｔ−Ｂｕｙフラグを「Ｔｒｕｅ」にする（Ｓ５９）。一方、割引フラグが「０」の場合、データ処理部２０４は買物メモフラグが「１」又は「２」であるか否かを判断する（Ｓ６２）。判断の結果、買物メモフラグが「１」又は「２」の場合、データ処理部２０４はＭｕｓｔ−Ｂｕｙフラグを「Ｔｒｕｅ」にする（Ｓ５９）。一方、買物メモフラグが「１」又は「２」でない場合、つまり「０」の場合、データ処理部２０４はＭｕｓｔ−Ｂｕｙフラグを「Ｆａｌｓｅ（偽）」にする（Ｓ６３）。
【０１２５】
ステップＳ５８〜Ｓ６３の結果、底値又はほぼ底値の商品、安値の商品、高割引率の商品、又は購入予定の商品についてはＭｕｓｔ−Ｂｕｙフラグが「Ｔｒｕｅ」になる。
【０１２６】
以上の結果、配信データ４００の作成が完了し、データ処理部２０４はこの完成した配信データを携帯電話機１０に送信する（Ｓ６４）。続いて、データ処理部２０４は広告の配信数をカウントし、広告データベース２０３内にある配信広告管理テーブル５００に記録する（Ｓ６５、図５中の▲３▼）。配信広告管理テーブル５００には、利用者ＩＤ、店コード、配信数、及び発行ポイントが記録される。配信数は店舗ごとにカウントされる。配信数は１つの広告商品につき１つカウントアップされてもよいし、１つの配信データ４００につき１つカウントアップされてもよい。発行ポイントは配信数に応じて発行される。
【０１２７】
一方、携帯電話機１０は配信データ４００を受信し（Ｓ６６）、買物メモ１５２の中から大分類識別子「９９９」の商品を検索する（Ｓ６７）。大分類識別子「９９９」の商品が存在する場合、携帯電話機１０はその商品に関する情報を受信した配信データ４００に追加する（Ｓ６８、図５中の▲４▼）。具体的には、買物メモ１５２に登録されている中分類を配信データ４００の小分類の欄に登録する。また、携帯電話機１０は底値フラグ、安値フラグ及び割引フラグを「０」にし、買物メモフラグを「１」にする。さらに、携帯電話機１０はＭｕｓｔ−Ｂｕｙフラグを「Ｔｒｕｅ」にする。
【０１２８】
上述した配信処理の結果、携帯電話機１０はその所有者たる買い主ごとにカスタマイズされた配信データ４００を取得することになる。最後に、携帯電話機１０はその配信データ４００を登録し、後述する広告表示機能を実行することにより買い主の閲覧に供する（Ｓ６９）。
【０１２９】
４−２．広告表示機能
次に、本システムの広告表示機能を説明する。
【０１３０】
４−２−１．買物リスト表示機能
買物リスト表示機能は、上述したＭｕｓｔ−Ｂｕｙフラグが「Ｔｒｕｅ」になっている商品の情報を携帯電話機１０上に表示する機能である。具体的には、携帯電話機１０は表示部１０７上に図１０に示すような買物リストを表示する。買物リストの上部には、店舗名３００（図１０の例では「Ａスーパー」）を表示する。
【０１３１】
携帯電話機１０は、Ｍｕｓｔ−Ｂｕｙフラグが「Ｔｒｕｅ」になっている商品を特定し、その広告情報を表示する。具体的には、小分類名（商品名）３０１、広告表示数量３０２、広告表示価格３０９，３０６を表示する。表７に示した配信データ４００の例では、店コード「００１」の「Ａスーパー」の広告情報１００であってＭｕｓｔ−Ｂｕｙフラグが「Ｔｒｕｅ」になっている商品は、「レタス」、「大根」、「トイレットペーパーＴＡ」である。よって、携帯電話機１０はこれらの商品の広告情報を表示する。「Ａスーパー」の広告情報１００ではないが、「サラダ油」は買物メモ１５２に登録され、Ｍｕｓｔ−Ｂｕｙフラグが「Ｔｒｕｅ」になっているから、その小分類名も併せて表示する。
【０１３２】
また、携帯電話機１０は、底値フラグが「１」になっている商品を特定し、その広告表示価格３０９の右横に下向き矢印３０３を点滅表示する。これにより、買い主は底値以下の商品を容易に認識することができる。携帯電話機１０はさらに、底値フラグが「２」になっている商品を特定し、上記表示した矢印３０４を表示する。これにより、買い主はほぼ底値の商品を容易に認識することができる。また、携帯電話機１０は、安値フラグが「１」になっている商品を特定し、その広告表示価格３０９に下線３０５を表示する。これにより、買い主は近隣の店舗の中で最も安い商品を容易に認識することができる。また、携帯電話機１０は、割引フラグが「１」になっている商品を特定し、その広告表示価格３０６を他と異なる色（たとえば赤）で表示する。これにより、買い主は希望割引率以上に割り引かれている商品を容易に認識することができる。また、携帯電話機１０は、買物メモフラグが「１」になっている商品を特定し、その商品名３０１の左横に記号３０７を表示する。これにより、買い主は買物メモ１５２に登録した商品を容易に認識することができる。また、図１０の例では示されていないが、携帯電話機１０は、買物メモフラグが「２」になっている商品を特定し、その商品名の左横に記号を点滅表示する。これにより、買い主は買物メモ１５２に登録した商品であって希望購入価格以下の商品を容易に認識することができる。
【０１３３】
４−２−２．一般広告表示機能
広告表示機能は、上述したように主に売り主に有用な広告情報のみを表示するものであるが、その他一般の広告情報も表示することもできる。図１１は、買物リストにない商品の広告情報を表示する手順を説明するための画面遷移図である。買い主が買物リストにない商品の広告情報を閲覧したい場合、図１０に示した買物リスト画面中のメニューボタン３０８をクリックする。これにより、携帯電話機１０は図１１に示すようにサブメニュー画面Ｄ１を表示する。サブメニュー画面Ｄ１には複数のサブメニューが表示される。買い主がこれらのサブメニューの中から「４．その他価格一覧」を選択すると、サブメニュー画面Ｄ１はその他価格一覧画面Ｄ２に切り替わる。その他価格一覧画面Ｄ２には、買物リストには挙がらなかったが、広告されている商品の件数が大分類ごとに表示される。買い主はその他価格一覧画面Ｄ２上で所望の大分類を選択する。たとえば「３．青果」が選択されると、その他価格一覧画面Ｄ２は選択された大分類「青果」に属する商品情報を列挙した青果画面Ｄ３に切り替わる。ここで、買い主が「玉ねぎ」の購入を予定しており、買い物する際に忘れないように買物リストに挙げておきたい場合、買い主はメニューボタン３０８をクリックする。これにより、青果画面Ｄ３は再びサブメニュー画面Ｄ１に切り替わる。買い主がサブメニューの中から「１．リストへ追加」を選択すると、携帯電話機１０は「玉ねぎ」の買物メモフラグを「０」から「１」に変更し、かつＭｕｓｔ−Ｂｙフラグを「Ｆａｌｓｅ」から「Ｔｒｕｅ」に変更する。これにより、サブメニュー画面Ｄ１は買物リスト画面Ｄ４に切り替わる。この買物リスト画面Ｄ４には追加した「玉ねぎ」が表示されている。
【０１３４】
４−２−３．底値確認機能
底値確認機能は、買物リスト画面に表示された商品の底値を確認できるようにする。図１２を参照して、買物リスト画面に表示された商品の底値を知りたい場合、買い主は買物リストの中から所望の商品を選択し、メニューボタン３０８をクリックとする。これにより、買物リスト画面はサブメニュー画面Ｄ１に切り替わる。買い主がサブメニューの中から「３．底値確認」を選択すると、携帯電話機１０は広告配信装置２０に接続され、価格マスタ８００から選択された商品の底値情報（底値表示数量、底値表示価格）を取得する。携帯電話機１０は底値確認画面Ｄ５上に取得した底値表示数量及び底値表示価格を表示する。
【０１３５】
４−２−４．他店価格確認機能
他店舗確認機能は、買物リスト画面に表示された商品の他店舗での広告表示価格を確認できるようにする。図１３を参照して、買物リスト画面に表示された商品の他店舗での広告表示価格を知りたい場合、買い主は買物リストの中から所望の商品を選択し、メニューボタン３０８をクリックする。図１３の例では「レタス」が選択されている。これにより、買物リスト画面はサブメニュー画面Ｄ１に切り替わる。買い主がサブメニューの中から「５．他店価格確認」を選択すると、携帯電話機１０は受信して保存している配信データ４００を検索し、上記で選択された商品の広告情報（広告表示数量、広告表示価格）を読み出す。図１３の例では選択された「レタス」の広告情報が読み出される。これにより、サブメニュー画面Ｄ１は店舗別価格確認画面Ｄ６に切り替わる。この画面Ｄ６には、検索で読み出された商品の広告表示数量及び広告表示価格が表示されている。図１３の例では、「Ａスーパー」に加えて、「Ｂスーパー」の「レタス」の広告表示数量及び広告表示価格が表示されている。配信データ４００に選択された商品の広告情報がない場合、携帯電話機１０は広告配信装置２０に接続され、価格マスタ８００から他の店舗の広告情報を取得する。
【０１３６】
４−２−５．通常価格確認機能
通常価格確認機能は、買物リスト画面に表示された商品の通常表示価格を確認できるようにする。図１４を参照して、買物リスト画面に表示された商品の通常表示価格を知りたい場合、買い主は買物リストの中から所望の商品を選択し、メニューボタン３０８をクリックする。図１４の例では「トイレットペーパーＴＡ」が選択されている。これにより、買物リスト画面はサブメニュー画面Ｄ１に切り替わる。買い主がサブメニューの中から「６．通常価格確認」を選択すると、携帯電話機１０は広告配信装置２０に接続され、広告データベース２０３から選択された商品の通常情報（通常表示数量、通常表示価格）を取得する。これにより、サブメニュー画面Ｄ１は通常価格確認画面Ｄ７に切り替わる。図１４の例では選択された「トイレットペーパーＴＡ」の通常表示数量及び通常表示価格が表示されている。
【０１３７】
５．広告配信システムの効果
以上のように本システムによれば、売り主の操作に応じて所望の広告を登録し、その登録された広告を買い主の携帯電話機１０に配信しているため、売り主は広告を簡易かつ広く買い主に配信することができる。しかも、底値、安値、割引など、買い主に有用な情報を付加して広告を配信しているため、買い主は買い得な商品の広告だけを閲覧することができる。また、底値でなくてもほぼ底値とみなす底値差率や希望割引率を買い主ごとに設定しているため、買い主は自らが決めた条件を満たす広告だけを閲覧することができる。また、買い主の居住地域又はその隣接地域内にある店舗の広告だけを配信しているため、売り主は近隣に住む買い主だけに広告を配信することができ、買い主は近隣にある店舗の広告だけを閲覧することができる。また、一般の広告情報とともに底値、安値、割引などの情報を含む配信データ４００を携帯電話機１０に配信しているため、携帯電話機１０は広告配信装置２０に頻繁にアクセスすることなく配信データ４００に基づいて広告を表示することができる。そのため、買い主は、場所、時間、通信料を気にせず、自由に所望の広告を閲覧することができる。また、広告は買い主に有用な情報とともに携帯電話機１０のディスプレイという限られたスペースで効率よく表示されるため、買い主は有用な広告情報を視覚的に素早く認識することができる。
【０１３８】
６．他の実施の形態
上述した実施の形態では、買物メモ１５２に手動で入力された商品の情報は携帯電話機１０から広告配信装置２０に送信されていない。そのため、この商品について言えば買物メモ１５２は買い主の備忘メモとしての役割を果たすのみである。しかし、買物メモ１５２に登録された商品は買い主の購入予定商品であるため、その商品に関連する広告は買い主だけでなく売り主にとっても有用な情報である。そこで、買物メモ１５２を広告配信装置２０に送信し、その商品に関連する広告をその買い主の携帯電話機１０に配信するようにしてもよい。
【０１３９】
次の表８は、この実施の形態で用いられる配信一時ファイル３１０の構成を示す。
【０１４０】
【表８】

前述の表６と異なり、この配信一時ファイル３１０には小分類ごとに１又は２以上のキーワードが登録されている。たとえば店コード「００１」、大分類識別子「００３」、中分類識別子「００１」、小分類識別子「００１」の商品に対しては、「レタス」、「野菜」、「サラダ」といったキーワードが登録されている。
【０１４１】
以下、図１５及び図１６を参照して、この実施の形態による広告の配信処理を説明する。ただし、前述の実施の形態と異なる部分を説明し、同じ部分はその説明を援用する。
【０１４２】
携帯電話機１０は、広告配信装置２０に広告情報を要求するとき、買物メモ１５２、価格差率１５４、利用者情報１６０の全てを広告配信装置２０に送信する（Ｓ４０、図１５中の▲１▼）。前述の実施の形態と異なり、手動で買物メモ１５２に登録された大分類及び中分類識別子「９９９」の商品も送信する。
【０１４３】
広告配信装置２０は、配信一時ファイル３１０に登録されているキーワードを順に選択し、その選択したキーワードで買物メモ１５２を検索する（Ｓ１００〜Ｓ１０５）。具体的には、広告配信装置２０はキーワードカウント数Ｎを「０」にリセットする（Ｓ１００）。続いて、広告配信装置２０は配信一時ファイル３００にキーワードがあるか否かを判断する（Ｓ１０１）。キーワードがない場合、広告配信装置２０は直ちに買物メモフラグを「０」にする（Ｓ４９）。一方、キーワードがある場合、広告配信装置２０はキーワードカウント数Ｎをインクリメントし（Ｓ１０２）、Ｎ個目のキーワードを選択する（Ｓ１０３）。続いて、広告配信装置２０はその選択したキーワードで買物メモ１５２を検索し（Ｓ１０４）、そのキーワードが買物メモ１５２に含まれているか否かを判断する（Ｓ１０５）。含まれている場合は検索を終了し、次のステップＳ１０６に進むが、含まれていない場合はステップＳ１０１に戻り、検索を繰り返す。
【０１４４】
検索の結果、買物メモ１５２に含まれるキーワードを見つけた場合、広告配信装置２０はそのキーワードに対応する商品の小分類識別子が「９９９」か否かを判断する（Ｓ１０６）。判断の結果、小分類識別子が「９９９」の場合、広告配信装置２０は買物メモフラグを「１」にする（Ｓ４７）。一方、小分類識別子が「９９９」でない場合、広告配信装置２０は前述と同様に買値基準価格を算出し（Ｓ４５）、広告内容基準価格を算出した買値基準価格と比較し（Ｓ４６）、広告内容基準価格が買値基準価格以下の場合、買物メモフラグを「２」にし（Ｓ４７）、広告内容基準価格が買値基準価格以下でない場合、買物メモフラグを「１」にする（Ｓ４８）。買物メモフラグが「１」又は「２」の場合、その商品のＭｕｓｔ−Ｂｕｙフラグは「Ｔｒｕｅ」になる（Ｓ５９）。
【０１４５】
たとえば表８に示した買物メモ１５２の「油」に注目すると、広告配信装置２０は配信一時ファイル３１０内のキーワードが買物メモ１５２に含まれているか否かを検索する。その結果、小分類識別子「９９９」の小分類名「○社オリーブオイル」に対応するキーワード「油」が買物メモ１５２に含まれていると判断する。したがって、小分類識別子「９９９」の小分類名「○社オリーブオイル」の買物メモフラグが「１」になり、かつＭｕｓｔ−Ｂｙフラグが「Ｔｒｕｅ」になる。
【０１４６】
以降の動作は図６と同じで、広告配信装置２０は配信データ４００を携帯電話機１０に配信する（Ｓ６４，図１５中の▲２▼）。
【０１４７】
なお、広告配信装置２０はステップＳ６５で広告配信数をカウントした後、ステップＳ４１で受信した買物メモ１５２を記録する（Ｓ１１０）。記録された買物メモ１５２は広告配信装置２０で分析され、その分析結果は今後の広告戦略の資料として店舗で利用される。
【０１４８】
また、携帯電話機１０はステップＳ６６で配信データ４００を受信した後、前述のステップＳ６７及びＳ６８の処理を行うことなく、その配信データ４００を登録し、広告表示機能を実行する（Ｓ６９）。
【０１４９】
以上の実施の形態によれば、広告配信装置２０は配信一時ファイル３１０に登録されているキーワードで買物メモ１５２を検索し、買物メモ１５２に登録された商品に関連する広告をその買い主の携帯電話機１０に送信しているため、買い主は買物メモ１５２に登録した商品に関連する広告を閲覧することができる。
【０１５０】
以上、本発明の実施の形態を例示したが、本発明はその他の形態でも実施可能である。
【０１５１】
上記実施の形態では広告配信装置２０側で配信データ４００を作成しているため、携帯電話機１０の処理負荷は小さい。しかし、広告配信装置２０から配信一時ファイル３００を携帯電話機１０に送信し、携帯電話機１０側で配信データ４００を作成するようにしてもよい。また、広告登録端末３０はなくてもよく、広告配信装置２０と一体化されていてもよい。また、上記の有効日付は１日であるが、有効日付に代えて有効期間を登録するようにしてもよい。さらに上記システムは多店舗が参加する場合で説明したが、１つしか店舗が参加しない場合も同様に本発明は適用可能である。ただし、１つしか店舗がない場合、安値フラグは全て「０」に固定するか、削除する。
【０１５２】
以上、本発明の実施の形態を説明したが、上述した実施の形態は本発明を実施するための例示に過ぎない。よって、本発明は上述した実施の形態に限定されることなく、その趣旨を逸脱しない範囲内で上述した実施の形態を適宜変形して実施することが可能である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an advertisement distribution system and an advertisement distribution method, and more particularly, to an advertisement distribution system and an advertisement distribution method for distributing an advertisement of a product to a mobile phone.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a method for advertising a product or service, there is a method in which a newspaper is delivered to the public together with a newspaper with a leaflet for advertisement placed between newspapers. In general, in the distribution and retail businesses such as supermarkets and discount stores, it is an effective method to promote sales because the general consumers purchase the products they handle, etc. . However, the method of placing an advertisement or the like on a flyer is no longer an effective method for promoting sales. Newspaper buyers are decreasing year by year. In particular, the proportion of young people who subscribe to newspapers by home delivery is low. This is because information can be obtained from the Internet or television without obtaining information from newspapers. Another reason is that obtaining information from the Internet or a television is less expensive than obtaining information from a newspaper.
[0003]
Therefore, as a method of advertising a product or the like handled by the distribution / retail industry, an alternative method to the flyer has been required. As an advertising method replacing the flyer, there is a marketing method using the Internet or a mobile phone. There are two types of such marketing methods, an opt-in mail type and a privilege providing type. The opt-in mail type is a marketing method of transmitting a direct mail by e-mail to a user who has previously received the direct mail. The user can select an item of interest or the like from a large number of information in advance and receive information on the item or the like by e-mail. The privilege providing type is a marketing method of providing a privilege such as points to a user based on the reception result as a price for receiving a banner advertisement or an opt-in mail. However, such opt-in mail type and privilege providing type marketing methods can make maximum use of the features that the mobile phone is a medium capable of two-way communication and that the mobile phone is highly likely to be always carried. Absent.

An advertisement distribution system according to one aspect of the present invention includes an advertisement storage unit that stores an advertisement for a product including a price of a product input in response to a request from a seller, and an advertisement for a product stored in the advertisement storage unit that is stored in an advertisement storage unit. Advertising distribution means for distributing to a mobile phone; bottom price storage means for storing a bottom price of a product; bottom product search means for searching for a product whose price is equal to or less than the bottom price stored in the bottom price storage means from the advertisement storage means; Display means for displaying, on a mobile phone, a product retrieved by the means.
[0007]
According to this advertisement distribution system, an advertisement input in response to a seller's request is distributed to a buyer's mobile phone, and products below the floor price are displayed on the mobile phone. , And buyers can easily recognize products below the bottom price.
[0008]
An advertisement distribution system according to another aspect of the present invention is an advertisement distribution system including a mobile phone and an advertisement distribution device connectable to the mobile phone. The advertisement distribution device includes an advertisement storage unit that stores an advertisement of a product including a price of the product input in response to a seller's request, a bottom price storage unit that stores a bottom price of the product, and a price stored in the bottom price storage unit. The system includes a bottom price search unit for searching for a product having a bottom price or less from the advertisement storage unit and adding bottom price information to the searched product, and an advertisement distribution unit for delivering an advertisement for the product to the mobile phone together with the bottom price information. The mobile phone includes a display unit that extracts and displays an advertisement of a product to which bottom price information has been added from advertisements of the product distributed from the advertisement distribution device.
[0009]
According to this advertisement distribution system, an advertisement input in response to a seller's request is distributed together with bottom price information to a buyer's mobile phone, and an advertisement for a product with a price lower than the bottom price is extracted from the advertisement for the product, and , The buyer can only view advertisements for products below the floor price.

Preferably, when the price of the product stored in the advertisement storage means is lower than the bottom price stored in the bottom price storage means, the advertisement distribution device further stores the bottom price stored in the bottom price storage means in the advertisement storage means. And a bottom price updating means for rewriting to a price of
[0011]
Preferably, the mobile phone includes means for registering the allowable range of the bottom price in accordance with the operation of the buyer, and means for transmitting the registered allowable range of the bottom price to the advertisement distribution device. The bottom price searching means also searches for products whose price is within the allowable range of the bottom price transmitted from the mobile phone, in addition to the products having the bottom price or lower.
[0012]
In this case, since a condition that is not a bottom price but is regarded as a bottom price is set for each buyer, the buyer can browse only advertisements having a bottom price that satisfy the conditions determined by the buyer.
[0013]
An advertisement distribution system according to still another aspect of the present invention is an advertisement distribution system including a mobile phone and an advertisement distribution device connectable to the mobile phone.

[0033]
2. Main functions of the ad distribution system
The present system mainly has an advertisement distribution function, an advertisement display function, an advertisement distribution result introduction function, and a point redemption function. Hereinafter, each function will be described.
[0034]
2-1. Ad serving function
The advertisement distribution function is a function of editing a large number of registered advertisements and distributing them to the buyer's mobile phone 10 so that useful advertisements for the buyer can be displayed on the mobile phone 10. The advertisement distribution function includes a bottom price notification function, a low price notification function, and a bargain notification function. The bottom price notification function is a function of notifying the bottom price (the lowest price among the prices of any advertised products so far) among the currently advertised products. When a plurality of stores participate in the system, the lowest advertising price in all stores is the bottom price. When only one store participates in the present system, the lowest advertising price in the store at that store becomes the bottom price. The low price notification function is a function for notifying the lowest price (low price) of the same type of product currently advertised in a plurality of stores. The bargain notification function is a function of notifying a product that is cheaper than usual among products currently advertised in one store.
[0035]
2-2. Ad display function
The advertisement display function is a function of displaying the distributed advertisement on the display screen of the mobile phone 10 as a shopping list useful for the buyer. Specifically, the shopping list displays the bottom price, low price, and bargain items notified by the advertisement distribution function. The shopping list also displays products registered in the shopping memo. In the shopping memo, a product that the buyer plans to purchase is registered.
[0036]
2-3. Ad delivery performance inquiry function
The advertisement distribution result function is a function for inquiring about the number of advertisements targeted for the shopping list among the distributed advertisements. This feature allows the seller to determine the effectiveness of the advertisement compared to others. In addition, the seller can confirm what kind of buyer has used the registered advertisement. Thus, this feature helps improve advertising planning.
[0037]
2-4. Point reduction function
The point redemption function is a function of issuing service points to the buyer according to the number of distributed advertisements. The number of delivered advertisements can be totaled for each seller and for each buyer. Thus, the seller can issue service points that can be used only in his own store only to the buyer who has received his own advertisement. In addition, by increasing the number of issued points according to the number of received advertisements, the seller can return the packet reception fee for the mobile phone 10 to the buyer.
[0038]
In the case of the conventional point system that issues points in response to clicks on opt-in emails and banner advertisements, points issued at one store are used at another store, or points issued at another store are used at Often used in. In contrast, the point redemption function issues points for each store. Since the service of issuing points exclusively for the store has already been established in supermarkets and the like, this point redemption function is easy to appeal to the buyer. It is also expected that the buyer will use the acquired points at the store that issued the points.
[0039]
3. Overall configuration of the ad distribution system
Next, the configuration of the present system will be described in detail with reference to FIG.
[0040]
The mobile phone 10 includes a data processing unit 101 such as a CPU, a RAM 102, an EEPROM 103, an antenna 104, a transmission / reception unit 105, an input unit 106 such as a numeric keypad or a cursor key, a display unit 107 such as a liquid crystal display, a battery. 108 and an interface (I / F) unit 109. The mobile phone 10 is mounted on a power adapter 110, and a current is supplied from the power adapter 110 to the battery 108 through the I / F unit 109, and the battery 108 is charged. The data processing unit 101 executes a normal mobile phone function using the RAM 102, the EEPROM 103, the transmission / reception unit 105, the input unit 106, the display unit 107, and the I / F unit 109, and executes the above-described advertisement display function.
[0041]
The advertisement distribution device 20 includes a data processing unit 204 such as a CPU, and a data storage unit 201 such as a ROM, a RAM, and a hard disk. The data storage unit 201 includes a common database 202 and an advertisement database 203. The common database 202 includes a classification master 600, a product master 700, a price master 800, and a region master 900. The data processing unit 204 performs the above-described advertisement distribution function using the common database 202 and the advertisement database 203. The advertisement created by the data processing unit 204 is transmitted from the antenna 404 of the wireless base station 40 to the mobile phone 10.
[0042]
The advertisement registration terminal 30 inputs a desired advertisement according to the seller's operation, and transmits the input advertisement to the advertisement distribution device 20 via the network 50.
[0043]
3-1. Ad database structure
Advertising information 100 is registered in the advertising database 203 for each store as shown in Table 1 below.
[0044]
[Table 1]

Referring to Table 1, the advertisement information 100 of each store includes a store code column, an effective date column, a product classification column, an advertisement column, and a normal column. In the column of store code, an identification number uniquely assigned to each store is recorded. The effective date column records the effective date of the advertisement. In the column of product classification, a classification number for specifying each product is recorded. The product classification column further includes a large classification column, a medium classification column, and a small classification column. A major classification number is recorded in the major classification column, a middle classification number is recorded in the middle classification column, and a small classification number and a product name are recorded in the minor classification column. The content of the advertisement is recorded in the advertisement column. The advertisement column further includes an advertisement display quantity column, an advertisement display price column, and an advertisement reference price column. In the column of the advertisement display quantity, the sales unit of the advertisement product (the advertisement display quantity) is recorded. The selling price (advertising display price) of the advertising product is recorded in the advertising display price column. In the column of advertisement reference price, a price per reference unit of the advertisement product (advertisement reference price) is recorded.
[0045]
In the example shown in Table 1, three shops sell onions for 398 yen, while shop B sells one onion for 85 yen. Therefore, even if the advertisement display prices are simply compared, it is not possible to determine which store has the cheaper onion. Therefore, it is necessary to determine the number or quantity of commodities when comparing prices. The number or quantity of the products is a reference unit, and the price per reference unit is the reference price. The advertisement reference price is calculated by the following equation (1).
[0046]
Ad base price = Ad display price / Ad display quantity x Base unit (1)
[0047]
Since the reference unit of “onion” is “1”, the advertisement reference price of store A is “132.7 yen”, whereas the advertisement reference price of store B is “85.0 yen”. Therefore, the onion at B store is cheaper. The reference unit of each product is registered in the product master 700, which will be described later.
[0048]
In the ordinary column, the contents of sales of the commodity at the ordinary time are recorded. The normal column further includes a column for a normal display quantity, a column for a normal display price, and a column for a normal reference price. In the column of the normal display quantity, the sales unit (normal display quantity) of the product in the normal state is recorded. In the column of the normal display price, the selling price of the product at normal time (normal display price) is recorded. In the column of the normal reference price, a price per reference unit of the commodity at normal time (normal reference price) is recorded. The normal reference price is calculated by the following equation (2).
[0049]
Normal base price = Normal display price / Normal display quantity x Base unit (2)
[0050]
3-2. Structure of Classification Master
Table 2 below shows an example of a table registered in the classification master 600.
[0051]
[Table 2]

Referring to Table 2, the classification master 600 has a table representing a system of product classification registered in the advertisement database 203. This table has a column of a large classification and a column of a medium classification. In the column of major classification, a major classification identifier and a major classification name are recorded. In the example of Table 2, the large classification identifier “001” indicates the large classification name “fresh fish”. The major category identifier “003” indicates the major category name “vegetables”. In the column of middle classification, a middle classification obtained by further subdividing the large classification, specifically, a middle classification identifier and a middle classification name are recorded. For example, in the column of the middle category corresponding to the major category name "vegetables" of the major category identifier "003", the middle category name "lettuce" of the middle category identifier "001" and the middle category name "letter" of the middle category identifier "002" are displayed. Radish "and the middle classification name" onion "of the middle classification identifier" 003 "are recorded.
[0052]
3-3. Structure of product master
Table 3 below shows an example of a table registered in the product master 700.
[0053]
[Table 3]

Referring to Table 3, product master 700 has a table for registering the names of products registered in advertisement database 203. This table includes a column of a large classification, a column of a middle classification, a column of a small classification, a column of a product name, and a column of a reference unit. The large classification column records a large classification identifier, and the middle classification column records a middle classification identifier. In the sub-category column, a sub-category obtained by further subdividing the middle class, specifically, a sub-class identifier is recorded. In the column of product name, a product name is recorded corresponding to the small classification identifier. In the example of Table 2, the small classification identifier “000”, the product name “toilet paper”, and the small classification identifier correspond to the middle classification identifier “001 (= toilet paper)” of the large classification identifier “004 (= daily necessities)”. "001" and a trade name "TA", and a small classification identifier "003" and a trade name "TB" are recorded. In the column of reference unit, a reference unit for calculating a reference price is recorded.
[0054]
3-4. Structure of price master
Table 4 below is an example of a table registered in the price master 800.
[0055]
[Table 4]

Referring to Table 4, price master 800 has a table for registering a bottom price and a low price of a product for each predetermined area. This table includes a column for an area code, a column for a product category, a column for a bottom price, and a column for a low price. In the area code column, an area code predetermined for each predetermined area is recorded. The classification column includes a large classification column, a medium classification column, and a small classification column. In these fields, the above-mentioned large classification identifier, medium classification identifier, and small classification identifier are recorded. The bottom price column includes a bottom price display quantity column, a bottom price display price column, a bottom price reference price column, and a reference date column. The Bottom Marked Quantity column records the quantity of the product per sale when the product was sold at the bottom price, and the Bottom Marked Price column records the price of the product per sale when the product was sold at the bottom price. The bottom price base price column records the base price of the product sold at the bottom price. In the example of Table 4, the product “Sanma” (major category “001”, middle category “001”, and minor category “001”) has a bottom price of 300 yen for three fishes. Accordingly, the bottom price display quantity is “3 fish” and the bottom price is “300 yen”. Also, since the reference unit of the product “Sanma” is “1” from the product master 700 shown in Table 2, the base price reference price is “100 yen”.
[0056]
In the column of the reference date, if the advertisement reference price is lower than the bottom price, or if the advertisement reference price is equal to or more than the bottom price, the difference is within a predetermined range (10% of the bottom price in this example). If so, the effective date of the advertisement is recorded. However, if the difference is out of the predetermined range, the reference date is maintained as before. That is, the reference date is updated when the bottom price reference price is updated, or when the advertisement reference price is close to the currently registered bottom price reference price without being updated. Therefore, if the bottom price is updated with an abnormally low advertisement price, the reference date will not be updated for a long time. Therefore, if the reference date is not updated for a long period of time, by clearing the registered bottom price base price, it is possible to prevent the bottom price base price from being updated with an abnormally low advertisement base price and not being updated continuously thereafter be able to.
[0057]
In the column of the low reference price, the advertisement reference price of the cheapest product among the plurality of stores is recorded.
[0058]
3-5. Configuration of regional master

[0059]
[Table 5]

Referring to Table 5, area master 900 has a table for specifying the location area of each store. This table has a column of a region code and a column of a store code. In the store code column, one or more store codes are recorded corresponding to one area code. In the example of Table 5, two store codes “001” and “002” are recorded corresponding to the area code “001”. That is, the store code “001” is recorded in correspondence with not only the area code “001” but also the area code “002”. Even if the store of “001” actually exists in the region of “002”, if the region of “001” is adjacent to the region of “002”, the store code can be recorded in this manner. The advertisement of the store “001” can be distributed not only to the area “002” but also to the area “001”.
[0060]
4. Operation of the ad distribution system
Next, the operation of the present system will be described. The present system mainly performs two operations of an advertisement distribution function and an advertisement display function.
[0061]
4-1. Ad serving function
The operation by the advertisement distribution function is performed in the order of advertisement registration processing, price master update processing, distribution temporary file creation processing, and distribution processing. Hereinafter, each process will be described.
[0062]
4-1-1. Ad registration process
First, an advertisement registration process will be described with reference to FIGS. In this process, the seller registers a desired advertisement in the advertisement database 203 of the advertisement distribution device 20 using the advertisement registration terminal 30. Hereinafter, the details of this processing will be described.
[0063]
First, the advertisement registration terminal 30 inputs the effective date of the advertisement according to the seller's operation (S1).
[0064]
Subsequently, the advertisement registration terminal 30 refers to the classification master 600 and acquires all the large classifications (S2). The advertisement registration terminal 30 displays the acquired large classification on a display (not shown). The advertisement registration terminal 30 selects a desired one from the displayed large categories according to the seller's operation (S3). The advertisement registration terminal 30 searches the classification master 600 and acquires all the intermediate classifications belonging to the selected large classification (S4). The advertisement registration terminal 30 displays the acquired middle classification on a display.
[0065]
If the displayed middle category includes a middle category for which an advertisement is to be registered, the seller selects the middle category, but if not, inputs a desired middle category. If there is a middle category, the advertisement registration terminal 30 selects a desired middle category from the category master 600 according to the seller's operation, and proceeds to step S6 (S5). On the other hand, when there is no middle classification and the user inputs the advertisement, the advertisement registration terminal 30 proceeds to step S8 (S5).
[0066]
When the middle class is selected from the class master 600, the advertisement registration terminal 30 searches the product master 700 and acquires all the small classes belonging to the selected middle class (S6). The advertisement registration terminal 30 displays the acquired minor classification on a display. The advertisement registration terminal 30 selects a desired one from the displayed small categories according to the seller's operation (S7). On the other hand, when the seller inputs a desired middle category, the advertisement registration terminal 20 sets both the middle category identifier and the minor category identifier to "999" (S8), and inputs a desired minor category name according to the seller's operation. (S9).
[0067]
Subsequently, the advertisement registration terminal 30 inputs the contents of the advertisement according to the seller's operation (S10). Specifically, an advertisement display quantity which is a sales unit of the advertisement product and an advertisement display price which is a sales price of the advertisement product are input. The advertisement registration terminal 30 calculates the advertisement reference price by the above-described equation (1) based on the input advertisement display quantity and advertisement display price and the reference unit registered in the product master 700 (S11).
[0068]
Subsequently, the advertisement registration terminal 30 transmits the advertisement information to the advertisement distribution device 20 and registers the advertisement information in the advertisement database 203 (S12). Specifically, the entered advertisement display quantity is recorded in the advertisement display quantity field, the entered advertisement display price is recorded in the advertisement display price field, and the calculated advertisement reference price is recorded in the advertisement reference price field. Record.
[0069]
When all the advertisements have been registered, the advertisement registration terminal 30 ends the above-described advertisement registration process. However, when the advertisement registration terminal 30 has not completed the advertisement registration process, the process returns to step S3 to repeat the advertisement registration process.
[0070]
Although not shown in the flow chart of FIG. 2, when the advertising content is input in step S10, if the selling content of the product under normal conditions is not yet registered in the advertising database 203, the content is also input. I do. Specifically, a normal display quantity, which is a sales unit of the product in normal time, and a normal display price, which is the selling price of the product in normal time, are input. When calculating the advertisement reference price in step S11, the advertisement registration terminal 30 uses the above-described formula (2) based on the input normal display quantity and normal display price and the reference unit registered in the product master 700 to calculate the normal reference price. The price is also calculated. When registering the advertisement information in step S12, the advertisement registration terminal 30 also registers the sales information of the product in the normal state. Specifically, the entered normal display quantity is recorded in the normal display quantity field, the input normal display price is recorded in the advertisement display price field, and the calculated normal reference price is recorded in the normal reference price field. Record.
[0071]
In addition, when calculating the advertisement reference price and the normal reference price in step S11, the reference unit registered in the product master 700 is used, but the reference unit is also registered for the product not registered in the product master 700. Absent. Therefore, when calculating the advertisement reference price or the normal reference price of a product not registered in the product master 700, the reference unit is set to “1”. In the example of Table 1, "toothbrush" is registered in the advertisement information 100 of the store A, but "toothbrush" is not registered in the product master 700. Therefore, the reference unit is set to “1”, and the advertisement reference price “132.0 yen” (= 132 yen / line × 1 line) and the normal reference price “150.0 yen” (= 150 yen / line × 1).
[0072]
4-1-2. Price master update processing
Next, an update process of the price master 800 will be described with reference to FIGS. When the above-described advertisement registration processing is completed, the advertisement distribution device 20 starts updating the price master 800. This processing updates the bottom price and the low price registered in the price master 800 based on the advertisement information 100 registered in the advertisement database 203. Hereinafter, the details of this processing will be described.
[0073]
First, in the advertisement distribution device 20, the data processing unit 204 reads the advertisement information 100 on a certain product from the advertisement database 203 (S14).
[0074]
Subsequently, the data processing unit 204 searches the area master 900 of the common database 202 and reads the area code corresponding to the store code of the read advertisement information 100 (S15).
[0075]
Subsequently, the data processing unit 204 searches the price master 800, and specifies a product having the same region code as the read region code and having the same product classification as the product classification of the read advertisement information 100 (S16).
[0076]
Subsequently, the data processing unit 204 compares the advertisement reference price of the advertisement information 100 read in step S14 with the bottom price reference price of the product specified in step S16 (S17). As a result of the comparison, when the advertisement reference price is lower than the bottom price, the data processing unit 204 updates the bottom price with the advertisement reference price (S18). In this case, the data processing unit 204 also updates the bottom display price and the bottom display quantity of the price master 800 with the advertisement display price and the advertisement display quantity of the read advertisement information 100 (S18). Thereafter, the data processing unit 204 updates the reference date of the price master 800 with the effective date of the read advertisement information 100 (S20).
[0077]
On the other hand, when the advertisement reference price is not lower than the bottom price, the data processing unit 204 determines whether the advertisement reference price satisfies the following equation (3) (S19).
[0078]
Advertisement base price ≤ bottom price base price + 10% (3)
[0079]
When the advertisement reference price satisfies Expression (3), the data processing unit 204 updates the reference date of the price master 800 with the effective date of the advertisement information 100 in the same manner as described above (S20). On the other hand, when the advertisement reference price does not satisfy Expression (3), the data processing unit 204 does not update the reference date and proceeds to the next step S21. The predetermined ratio of the bottom price reference price is preset in the present system. In this example, the predetermined ratio is set to 10% of the bottom price reference price.
[0080]
Next, the data processing unit 204 compares the advertisement reference price of the advertisement information 100 read in step S14 with the low reference price of the product specified in step S16 (S21). As a result of the comparison, when the advertisement reference price is lower than the low reference price, the data processing unit 204 updates the low reference price with the advertisement reference price (S22). On the other hand, when the advertisement reference price is not lower than the low reference price, the data processing unit 204 does not change the low reference price and proceeds to the next step S23.
[0081]
Finally, the data processing unit 204 determines whether or not the price master update process has been performed on the advertisement information 100 on all the products registered in the advertisement database 203 (S23). If the price master update process has been performed on the advertisement information 100 for all products, the data processing unit 204 ends the price master update process. If not, the process returns to step S14 to repeat the price master update process.
[0082]
4-1-3. Temporary distribution file creation processing
Next, with reference to FIG. 1, FIG. 4, and FIG. 5, a process of creating the distribution temporary file 300 will be described. When the price master updating process described above is completed, the advertisement distribution device 20 starts the process of creating the distribution temporary file 300. This processing is performed based on the advertisement information 100 registered in the advertisement database 203 and the bottom price and the low price registered in the price master 800. The temporary distribution file 300 necessary for creating distribution data to the mobile phone 10 is stored in the temporary storage file 300. To create. Before describing the process of creating the temporary distribution file 300, the configuration of the temporary distribution file 300 will be described first.
[0083]
Table 6 below is an example of the temporary distribution file 300.
[0084]
[Table 6]

Referring to Table 6, in distribution temporary file 300, information necessary for creating distribution data to be distributed to mobile phone 10 is recorded. Specifically, the temporary delivery file 300 includes a column for an effective date, a column for a region code, a column for a store code, a column for a product classification (major classification, medium classification, and small classification), a column for a reference unit, , An advertisement (advertisement display quantity, advertisement display price, advertisement reference price), a low price flag column, a bottom price reference price column, and a normal reference price column. In the column of low price flag, a flag for identifying whether or not the advertisement reference price is low is recorded. In each column of the distribution temporary file 300, predetermined information is recorded by a temporary file creation process described later. Hereinafter, the details of the delivery temporary file creation process will be described.
[0085]
First, in the advertisement distribution device 20, the data processing unit 204 generates the advertisement information 100 (store code, effective date, large classification identifier, medium classification identifier, small classification identifier, advertisement display quantity, advertisement amount) for a certain product from the advertisement database 203. The display price, advertisement reference price, normal display quantity, normal display price, normal reference price) are read (S24).
[0086]
Subsequently, the data processing unit 204 searches the area master 900 of the common database 202, and adds an area code corresponding to the shop code read in step S24 (S25).
[0087]
Subsequently, the data processing unit 204 searches the classification master 600, and adds a major classification name and a middle classification name corresponding to the major classification identifier and the middle classification identifier read in step S24, respectively (S26).
[0088]
Subsequently, the data processing unit 204 searches the product master 700, and adds a reference unit corresponding to the minor classification identifier read in step S24 (S27).
[0089]
Subsequently, the data processing unit 204 searches the price master 800, and based on the area code read in step S25 and the product category (major category identifier, middle category identifier, small category identifier) read in step S24, the low price of the product. The base price and the bottom price base price are extracted (S28).
[0090]
Subsequently, the data processing unit 204 compares the advertisement reference price read in step S24 with the low reference price extracted in step S28 (S29). If the comparison result indicates that the advertisement reference price is equal to or lower than the low reference price, the low price flag is set to "1" (S30). On the other hand, when the advertisement reference price is higher than the low reference price, the low flag is set to “0” (S31).
[0091]
Subsequently, the data processing unit 204 adds the bottom price extracted in step S28 (S32).
[0092]
Subsequently, the data processing unit 204 registers the advertisement information, the area code, the major category name and the middle category name, the reference unit, the low price flag, and the bottom price reference price obtained in steps S24 to S28 and S30 to S33 in the temporary distribution file 300. (S33).
[0093]
Finally, the data processing unit 204 determines whether or not the distribution temporary file creation processing has been performed on the advertisement information 100 on all the products registered in the advertisement database 203 (S34). If the temporary distribution file creation processing has been performed for the advertisement information 100 for all products, the data processing unit 204 ends the temporary distribution file creation processing, but if not, returns to step S24 and repeats the temporary distribution file creation processing. .
[0094]
4-1-4. Delivery process
Next, an advertisement distribution process will be described with reference to FIGS. When the above-described temporary distribution file creation processing is completed, the preparation for advertisement distribution is completed. The advertisement distribution device 20 starts advertisement distribution processing in response to an advertisement distribution request from the mobile phone 10. This process is to create distribution data to the mobile phone 10 based on the created distribution temporary file. However, the same distribution data is not distributed to all buyers, but distribution data customized for each buyer is distributed. In order to customize the distribution data, the buyer registers necessary information in the mobile phone 10. Before describing the details of the distribution process, a method of registering this customization information will be described.
[0095]
First, the mobile phone 10 registers the shopping memo 152 in accordance with the operation of the buyer (S38). The shopping memo 152 is for registering a product that the buyer plans to purchase. There are two ways to register the shopping memo 152. One is a method of selecting one from commodities registered in the classification master 600. The other is a method of manually inputting an arbitrary product.
[0096]
First, a method of selecting a product from the classification master 600 will be described. Referring to FIG. 7, mobile phone 10 stores shopping memo 152 in EEPROM 103. The shopping memo 152 has a column of user ID, a column of merchandise classification (major classification and middle classification), a column of buying price, and a column of registration date. The buy price column further includes a quantity column and a price column.
[0097]
When the buyer registers the shopping memo 152, the mobile phone 10 displays a shopping memo screen 111 on the display unit 107. When registering the product to be purchased, the buyer selects “2. Add” on the shopping memo screen 111. As a result, the screen 111 is switched to the screen 112. The buyer selects “1. Select from classification master” on the screen 112. As a result, the mobile phone 10 is connected to the advertisement distribution device 20 via the wireless base station 40 and acquires the large classification and the medium classification from the classification master 600. As a result, the screen 112 is switched to the screen 113. On this screen 113, a plurality of acquired major categories are displayed. The buyer selects one of the displayed large categories to which the product to be purchased belongs. In the example of FIG. 7, the buyer has selected “4. When the buyer selects the large category, although not shown, the mobile phone 10 displays the middle category belonging to the selected large category. The buyer selects the middle category to which the product to be purchased belongs. The selected large category and middle category are recorded in the item category of the shopping memo 152.
[0098]
Subsequently, the buyer registers the purchase price information of the product belonging to the selected middle category. The purchase price information includes a purchase price quantity and a purchase price. The purchase price is the buyer's desired purchase quantity, and the purchase price is the buyer's desired purchase price. The desired purchase quantity is recorded in the quantity column of the shopping memo 152, and the desired purchase price is recorded in the price field of the shopping memo 152.
[0099]
Next, a method of manually inputting an arbitrary product will be described. If there is no classification to which the product to be purchased belongs in the classification master 600, the buyer selects “2. manual input” on the shopping memo screen 112 with reference to FIG. As a result, the screen 112 is switched to the screen 114. On this screen 114, a product name input unit 116 for inputting a name of a product to be purchased, a quantity input unit 117 for inputting a desired purchase quantity of the product, and a unit for inputting a unit of the product. The unit input section 118 is displayed. The buyer inputs the product name to the product name input section 116, the quantity to the quantity input section 117, and the unit to the unit input section 118. The input product name is recorded in the middle category column of the shopping memo 152, and the entered quantity and unit are recorded in the quantity column of the shopping memo 152. When an arbitrary product is manually input in this way, the identifier “999” is recorded in both the large classification and the middle classification in the shopping memo 152.
[0100]
In the user ID column of the shopping memo 152, the user ID of the user information 160 shown in FIG. 5 is recorded. In the column of registration date, the date when the shopping memo 152 was registered or updated is recorded.
[0101]
After registering the shopping memo 152, the mobile phone 10 registers the price difference rate 154 according to the operation of the buyer (S39). The price difference rate is for registering the bottom price difference rate that the buyer considers to be almost the bottom price even when the advertisement base price is higher than the bottom price base price, or registers the discount rate that the buyer considers to be bargain.
[0102]
Referring to FIG. 9, when the buyer registers a price difference rate, mobile phone 10 displays a screen 119 of the price difference rate on display unit 107. When the buyer selects “2. Add” on the screen 119, the mobile phone 10 is connected to the advertisement distribution device 20 via the wireless base station 40, and refers to the classification master 600 to acquire all major classifications. As a result, the screen 119 is switched to the screen 120, and the mobile phone 10 displays the acquired large classification on the screen 120. The buyer selects one of the displayed large categories for which the price difference rate is to be set. In the example of FIG. 9, the buyer has selected “3. When the large classification is selected, the screen 120 is switched to the screen 121. On the screen 121, a bottom price difference rate input section 122 for inputting a bottom price difference rate and a discount rate input section 123 for inputting a discount rate are displayed. The buyer inputs a desired bottom price difference rate to the bottom price difference rate input section 122 and inputs a desired discount rate to the discount rate input section 123. In the example of FIG. 9, a bottom price difference rate of “3%” is input, and a discount rate of “10%” is input.
[0103]
After the above-described registration of the customization information (shopping memo and price difference rate), when the buyer operates the mobile phone 10 to request the advertisement distribution, the advertisement distribution device 20 starts the advertisement distribution processing. Hereinafter, the details of the distribution process will be described with reference to FIGS. 1, 5, and 6.
[0104]
The mobile phone 10 transmits the shopping memo 152 (strictly a part thereof) and the price difference rate 154 registered above together with the user information 160 to the advertisement distribution device 20 (S40, (1) in FIG. 5). The advertisement distribution device 20 receives this (S41). At this time, the middle class identifier of the shopping memo 152 is transmitted, but the middle class name is not transmitted. This is because the middle classification name is registered in the classification master 600. In addition, the information of the product (the information on “salad oil” in the example of FIG. 5) manually input to the shopping memo 152 is not transmitted. This is because a manually input product does not have a regular classification code and cannot refer to the advertisement database 203 or the price master 800. However, the contents of the price difference rate 154 and the user information 160 are transmitted as they are. As a result, the advertisement distribution device 20 acquires the shopping memo 155 (a part of the shopping memo 152) as shown in FIG. Note that the user information 160 includes a user ID, a mail address, and an area code. These are registered in advance.
[0105]
After receiving the shopping memo 155 and the like, the advertisement distribution device 20 creates distribution data 400 based on the received shopping memo 155 and the distribution temporary file 300 created above, and transmits the distribution data 400 to the mobile phone 10 (FIG. 5). (2)).
[0106]
Table 7 below shows a configuration of the distribution data 400.
[0107]
[Table 7]

Referring to Table 7, distribution data 400 includes effective date, store code, product category (major category, medium category, small category), advertisement (advertisement display quantity and advertisement display price), and flag (bottom price flag, low price flag). , A discount flag, a shopping memo flag, and a Must-Buy flag). The bottom price flag is a flag for identifying whether or not the advertisement price of the product is at or below the bottom price or almost at the bottom price. The discount flag is a flag for identifying whether or not the advertisement price of the product is lower than usual. The shopping memo flag is a flag for identifying whether or not the product is registered in the shopping memo 155 and, if registered, whether or not the advertisement price of the product is equal to or less than a desired purchase price. The Must-Buy flag is a flag for identifying whether the product is bargain or planned to be purchased.
[0108]
Next, details of a method of creating the distribution data 400 will be described.
[0109]
In the advertisement distribution device 20, the data processing unit 204 reads necessary information from the distribution temporary file 300 created above (S42). Specifically, for a product having the same area code as the area code of the user information 160, the validity date, store code, product classification, advertisement display quantity, advertisement display price, and low price flag are read.
[0110]
Subsequently, the data processing unit 204 sets a shopping memo flag (S43 to S49). Specifically, the data processing unit 204 searches the shopping memo 155 (S43), and determines whether or not the product category is registered in the shopping memo 155 (S44). As a result of the determination, when the product classification is registered in the shopping memo 155, the data processing unit 204 calculates the purchase price base price by the following equation (4) (S45).
[0111]
Buy price base price = buy price / buy price quantity x base unit (4)
[0112]
The purchase price and the purchase price are read from the shopping memo 155, and the reference unit is read from the temporary distribution file 300. The purchase price reference price is a desired purchase price per reference unit.
[0113]
Subsequently, the data processing unit 204 compares the advertisement reference price with the calculated purchase price reference price (S46). When the comparison result indicates that the advertisement reference price is equal to or less than the purchase price reference price, the data processing unit 204 sets the shopping memo flag to “2” (S47). On the other hand, when the advertisement reference price is not lower than the purchase price reference price, the data processing unit 204 sets the shopping memo flag to “1” (S48).
[0114]
On the other hand, as a result of the determination in step S44, when the product classification is not registered in the shopping memo 155, the data processing unit 204 sets the shopping memo flag to “0” (S49).
[0115]
As a result of Steps S43 to S49, among the products registered in the shopping memo by the buyer, the products that are advertised at or below the desired purchase price have the shopping memo flag set to “2”, and are advertised at a price higher than the desired purchase price. The shopping memo flag is set to “1” for the product that is present. For items that are not registered in the shopping memo by the buyer, the shopping memo flag is set to “0”.
[0116]
Subsequently, the data processing unit 204 sets a bottom price flag (S50 to S54). Specifically, the data processing unit 204 compares the advertisement reference price with the bottom price reference price (S50). As a result of the comparison, when the advertisement reference price is equal to or lower than the floor price, the data processing unit 204 sets the floor price flag to “1” (S51). On the other hand, when the advertisement reference price is not lower than the floor price, the data processing unit 204 determines whether the advertisement reference price satisfies the following equation (5) (S52).
[0117]
Advertisement reference price ≤ bottom price base price x (1 + bottom price difference rate) (5)
[0118]
The advertisement reference price and the bottom price reference price are read from the distribution temporary file 300, and the bottom price difference rate is read from the price difference rate 154. As a result of the determination, when the advertisement reference price satisfies Expression (5), the data processing unit 204 sets the bottom price flag to “2” (S53). On the other hand, when the advertisement reference price does not satisfy Expression (5), the data processing unit 204 sets the bottom price flag to “0” (S54).
[0119]
As a result of Steps S50 to S54, the bottom price flag is set to "1" for products whose prices are below the bottom price. In addition, even if the product is not at or below the bottom price, the bottom price flag is set to "2" for a product having substantially the bottom price, and the bottom price flag is set to "0" for a product that is not substantially at the bottom price.
[0120]
Subsequently, the data processing unit 204 sets a discount flag (S55 to S57). Specifically, the data processing unit 204 determines whether the discount rate of the price difference rate 154 satisfies the following expression (6) (S55).
[0121]
Discount rate ≤ (normal reference price-advertisement reference price) / normal reference price x 100 (6)
[0122]
As a result of the determination, when the discount rate satisfies Expression (6), the data processing unit 204 sets the discount flag to “1” (S56). On the other hand, when the discount rate does not satisfy Expression (6), the data processing unit 204 sets the discount flag to “0” (S57).
[0123]
As a result of steps S55 to S57, the discount flag is set to "1" for a product discounted at or above the buyer's desired discount rate, and the discount flag is set to "0" for a product that is not so discounted.
[0124]
Subsequently, the data processing unit 204 sets the MUST-BUY flag (S58 to S63). Specifically, the data processing unit 204 determines whether the bottom price flag is “1” or “2” (S58). When the bottom value flag is “1” or “2” as a result of the determination, the data processing unit 204 sets the Must-Buy flag to “True (true)” (S59). On the other hand, if the bottom price flag is not “1” or “2”, that is, if it is “0”, the data processing unit 204 determines whether the low price flag is “1” (S60). If the result of the determination is that the low price flag is “1”, the data processing unit 204 sets the Must-Buy flag to “True” (S59). On the other hand, when the low price flag is “0”, the data processing unit 204 determines whether the discount flag is “1” (S61). As a result of the determination, when the discount flag is “1”, the data processing unit 204 sets the Must-Buy flag to “True” (S59). On the other hand, if the discount flag is “0”, the data processing unit 204 determines whether the shopping memo flag is “1” or “2” (S62). If the result of the determination is that the shopping memo flag is “1” or “2”, the data processing unit 204 sets the Must-Buy flag to “True” (S59). On the other hand, if the shopping memo flag is not “1” or “2”, that is, if it is “0”, the data processing unit 204 sets the Must-Buy flag to “False” (S63).
[0125]
As a result of steps S58 to S63, the Must-Buy flag is set to “True” for the commodity at the bottom or almost the bottom, the commodity at the low price, the commodity at the high discount rate, or the commodity to be purchased.
[0126]
As a result, the creation of the distribution data 400 is completed, and the data processing unit 204 transmits the completed distribution data to the mobile phone 10 (S64). Subsequently, the data processing unit 204 counts the number of distributions of the advertisement and records it in the distribution advertisement management table 500 in the advertisement database 203 (S65, (3) in FIG. 5). In the distribution advertisement management table 500, a user ID, a store code, the number of distributions, and an issue point are recorded. The number of distributions is counted for each store. The number of distributions may be incremented by one for one advertisement product, or may be incremented by one for one distribution data 400. Issue points are issued according to the number of distributions.
[0127]
On the other hand, the mobile phone 10 receives the distribution data 400 (S66), and searches the shopping memo 152 for a product with the large classification identifier "999" (S67). If there is a product with the large classification identifier “999”, the mobile phone 10 adds information on the product to the received distribution data 400 (S68, (4) in FIG. 5). Specifically, the middle category registered in the shopping memo 152 is registered in the subcategory column of the distribution data 400. The mobile phone 10 sets the bottom price flag, the low price flag, and the discount flag to “0”, and sets the shopping memo flag to “1”. Further, the mobile phone 10 sets the “Must-Buy” flag to “True”.
[0128]
As a result of the above-described distribution processing, the mobile phone 10 acquires distribution data 400 customized for each buyer who is the owner. Finally, the mobile phone 10 registers the distribution data 400, and executes the advertisement display function described later to make it available to the buyer (S69).
[0129]

Specifically, the mobile phone 10 displays a shopping list as shown in FIG. At the top of the shopping list, a store name 300 (“A supermarket” in the example of FIG. 10) is displayed.
[0131]
The mobile phone 10 specifies a product whose “Must-Buy” flag is “True” and displays the advertisement information. Specifically, a sub-category name (product name) 301, an advertisement display quantity 302, and advertisement display prices 309 and 306 are displayed. In the example of the distribution data 400 shown in Table 7, the advertisement information 100 of “A supermarket” with the store code “001” and the Must-Buy flag being “True” include “lettuce” and “radish”. "And" Toilet paper TA ". Therefore, the mobile phone 10 displays the advertisement information of these products. Although it is not the advertisement information 100 of “A supermarket”, “salad oil” is registered in the shopping memo 152 and the Must-Buy flag is set to “True”.
[0132]
In addition, the mobile phone 10 specifies a product whose bottom price flag is “1”, and blinks a downward arrow 303 to the right of the advertisement display price 309. As a result, the buyer can easily recognize the commodities below the bottom price. The mobile phone 10 further identifies a product whose bottom price flag is “2” and displays the displayed arrow 304. As a result, the buyer can easily recognize the commodity having the almost bottom price. In addition, the mobile phone 10 identifies a product whose low price flag is “1”, and displays an underline 305 on the advertisement display price 309 thereof. As a result, the buyer can easily recognize the cheapest product among the nearby stores. In addition, the mobile phone 10 specifies a product for which the discount flag is “1” and displays the advertisement display price 306 in a color different from the others (for example, red). As a result, the buyer can easily recognize the merchandise that has been discounted at or above the desired discount rate. In addition, the mobile phone 10 specifies a product whose shopping memo flag is “1”, and displays a symbol 307 on the left side of the product name 301. Thereby, the buyer can easily recognize the product registered in the shopping memo 152. Although not shown in the example of FIG. 10, the mobile phone 10 specifies a product whose shopping memo flag is “2” and blinks a symbol to the left of the product name. As a result, the buyer can easily recognize products registered in the shopping memo 152 that are lower than the desired purchase price.
[0133]
4-2-2. General ad display function
As described above, the advertisement display function mainly displays only advertisement information that is useful to the seller, but can also display other general advertisement information. FIG. 11 is a screen transition diagram for explaining a procedure for displaying advertisement information of a product not in the shopping list.

5. Effect of ad distribution system
As described above, according to the present system, a desired advertisement is registered according to the operation of the seller, and the registered advertisement is distributed to the mobile phone 10 of the buyer. Therefore, the seller can easily and widely distribute the advertisement to the buyer. Can be delivered. Moreover, since the advertisement is distributed with useful information such as the bottom price, the low price, and the discount added to the buyer, the buyer can view only the advertisement of the bargain product. In addition, since the bottom price difference rate and the desired discount rate that are not bottom prices but are regarded as bottom prices are set for each buyer, the buyer can browse only advertisements that satisfy the conditions determined by himself. In addition, since only advertisements for stores located in the buyer's residence area or its adjacent area are distributed, the seller can distribute advertisements only to buyers living nearby, and buyers can only advertise advertisements for nearby stores. Can be viewed.

6. Other embodiments
In the above-described embodiment, the product information manually input to the shopping memo 152 is not transmitted from the mobile phone 10 to the advertisement distribution device 20. Therefore, regarding this product, the shopping memo 152 only serves as a memorandum for the buyer. However, since the merchandise registered in the shopping memo 152 is a merchandise to be purchased by the buyer, the advertisement related to the merchandise is useful information not only for the buyer but also for the seller. Therefore, the shopping memo 152 may be transmitted to the advertisement distribution device 20, and the advertisement relating to the product may be distributed to the buyer's mobile phone 10.
[0139]
Table 8 below shows a configuration of the temporary delivery file 310 used in this embodiment.
[0140]
[Table 8]

Unlike Table 6 described above, one or two or more keywords are registered in the distribution temporary file 310 for each small classification. For example, keywords such as “lettuce”, “vegetables”, and “salad” are registered for products with a store code “001”, a large classification identifier “003”, a middle classification identifier “001”, and a small classification identifier “001”. ing.
[0141]
Hereinafter, an advertisement distribution process according to this embodiment will be described with reference to FIGS. However, portions different from the above-described embodiment will be described, and the description of the same portions will be cited.
[0142]
When requesting advertisement information from the advertisement distribution device 20, the mobile phone 10 transmits all of the shopping memo 152, the price difference ratio 154, and the user information 160 to the advertisement distribution device 20 (S40, (1) in FIG. 15). ). Unlike the above-described embodiment, the merchandise having the large classification and middle classification identifier “999” manually registered in the shopping memo 152 is also transmitted.
[0143]
The advertisement distribution device 20 sequentially selects the keywords registered in the distribution temporary file 310, and searches the shopping memo 152 using the selected keywords (S100 to S105). Specifically, the advertisement distribution device 20 resets the keyword count number N to “0” (S100). Subsequently, the advertisement distribution device 20 determines whether there is a keyword in the distribution temporary file 300 (S101). If there is no keyword, the advertisement distribution device 20 immediately sets the shopping memo flag to “0” (S49). On the other hand, when there is a keyword, the advertisement distribution device 20 increments the keyword count N (S102) and selects the Nth keyword (S103). Subsequently, the advertisement distribution device 20 searches the shopping memo 152 using the selected keyword (S104), and determines whether the keyword is included in the shopping memo 152 (S105). If it is included, the search ends, and the process proceeds to the next step S106. If it is not included, the process returns to step S101 and the search is repeated.
[0144]
As a result of the search, when a keyword included in the shopping memo 152 is found, the advertisement distribution device 20 determines whether or not the small classification identifier of the product corresponding to the keyword is “999” (S106). As a result of the determination, when the minor classification identifier is “999”, the advertisement distribution device 20 sets the shopping memo flag to “1” (S47). On the other hand, if the minor classification identifier is not “999”, the advertisement distribution device 20 calculates the purchase price reference price in the same manner as described above (S45), compares the advertisement content reference price with the calculated purchase price reference price (S46), and If the base price is equal to or lower than the purchase price base price, the shopping memo flag is set to "2" (S47). If the advertisement content base price is not equal to or lower than the purchase price base price, the shopping memo flag is set to "1" (S48). When the shopping memo flag is “1” or “2”, the Must-Buy flag of the product becomes “True” (S59).
[0145]
For example, focusing on “oil” of the shopping memo 152 shown in Table 8, the advertisement distribution device 20 searches whether or not the keyword in the temporary distribution file 310 is included in the shopping memo 152. As a result, it is determined that the keyword “oil” corresponding to the small category name “Olive Oil” of the small category identifier “999” is included in the shopping memo 152. Therefore, the shopping memo flag of the minor category name “○ company olive oil” of the minor category identifier “999” becomes “1” and the Must-By flag becomes “True”.
[0146]
The subsequent operation is the same as in FIG. 6, and the advertisement distribution device 20 distributes the distribution data 400 to the mobile phone 10 (S64, (2) in FIG. 15).
[0147]
After counting the number of advertisement distributions in step S65, the advertisement distribution device 20 records the shopping memo 152 received in step S41 (S110). The recorded shopping memo 152 is analyzed by the advertisement distribution device 20, and the analysis result is used in the store as a material of a future advertisement strategy.
[0148]
After receiving the distribution data 400 in step S66, the mobile phone 10 registers the distribution data 400 without executing the processes in steps S67 and S68, and executes the advertisement display function (S69).
[0149]
According to the above-described embodiment, the advertisement distribution device 20 searches the shopping memo 152 using the keyword registered in the temporary distribution file 310, and displays the advertisement related to the product registered in the shopping memo 152 on the mobile phone of the buyer. 10, the buyer can browse the advertisement related to the product registered in the shopping memo 152.
[0150]
The embodiment of the present invention has been described above, but the present invention can be implemented in other embodiments.
[0151]
In the above embodiment, the distribution data 400 is created on the advertisement distribution device 20 side, so that the processing load of the mobile phone 10 is small. However, the distribution temporary file 300 may be transmitted from the advertisement distribution device 20 to the mobile phone 10, and the mobile phone 10 may create the distribution data 400. The advertisement registration terminal 30 may not be provided, and may be integrated with the advertisement distribution device 20. Although the above-mentioned effective date is one day, an effective period may be registered instead of the effective date. Further, the above system has been described in the case where many stores participate, but the present invention is similarly applicable when only one store participates. However, if there is only one store, all low price flags are fixed to “0” or deleted.
[0152]
The embodiment of the present invention has been described above, but the above-described embodiment is merely an example for implementing the present invention. Therefore, the present invention is not limited to the above-described embodiment, and can be implemented by appropriately modifying the above-described embodiment without departing from the spirit thereof.
