Abstract

In the present invention a storage unit (101) stores intervals associated respectively with multiple products. A reception unit (102) receives from a shopper a request specifying, among products purchased by the shopper, a lower-limit product and an upper-limit product. An acquisition unit (103) determines a first retrieval interval, wherein a lower-limit value of a first lower-limit interval associated with the lower-limit product and an upper-limit value of a first upper-limit interval associated with the upper-limit product are set respectively as the lower-limit value and the upper-limit value. A retrieval unit (104) retrieves products associated with an interval overlapping the first retrieval interval. A presentation unit (105) presents to the shopper the products associated with the interval overlapping the first retrieval interval. When a product associated with the interval overlapping the first retrieval interval is stored in the storage unit (101) and the first lower-limit interval and the first upper-limit interval overlap, an updating unit (106) updates the upper-limit value of the first lower-limit interval to a lower value and updates the lower-limit value of the first upper-limit interval to a higher value, so that an overlap interval becomes smaller.

　インターネットショッピングサイトにおいて、衣類や靴など、同じ商品でも異なるサイズを有する商品が多数扱われている。このような商品は、実店舗と違って実際に手に取ったり、試着したりすることができないので、ショッパーにとって、希望のサイズの商品を選択するのは難しいという問題があった。このような事情を背景に、従来より、商品サイズの提示についてさまざまな技術が提案されている。例えば、特許文献１では、他のショッパーが購入した商品のサイズ及び評価を基に、試着を行わなくてもショッパーの体に合うサイズを提示する技術が開示されている。 ・ On the Internet shopping site, many items with the same size, such as clothes and shoes, are handled. Unlike actual stores, such products cannot be picked up or tried on, so it is difficult for shoppers to select products of the desired size. Against this background, various techniques have been proposed for presenting product sizes. For example, Patent Document 1 discloses a technique for presenting a size that fits a shopper's body without trying on, based on the size and evaluation of a product purchased by another shopper.

（３．実施形態に係る検索装置の概要構成）
　実施形態に係る検索装置１００は、図３に示すように、記憶部１０１と、受付部１０２と、取得部１０３と、検索部１０４と、提示部１０５と、更新部１０６と、から構成される。 (3. Outline configuration of search device according to embodiment)
As illustrated in FIG. 3, the search device 100 according to the embodiment includes a storage unit 101, a reception unit 102, an acquisition unit 103, a search unit 104, a presentation unit 105, and an update unit 106. .
　本実施形態において、ＣＰＵ　６０１及び記憶装置６０４が協働して、記憶部１０１として機能し、ＣＰＵ　６０１及びＮＩＣ　６０５が協働して、受付部１０２及び提示部１０５として機能し、ＣＰＵ　６０１が取得部１０３、検索部１０４、及び、更新部１０６として機能する。 In this embodiment, the CPU 601 and the storage device 604 cooperate to function as the storage unit 101, and the CPU 601 and the NIC 605 cooperate to function as the reception unit 102 and the presentation unit 105, and the CPU 601 acquires Functions as the unit 103, the search unit 104, and the update unit 106.
　記憶部１０１は、複数の商品のそれぞれに対応付けられる区間を記憶する。 The storage unit 101 stores a section associated with each of a plurality of products.
　複数の商品とは、電子市場で扱われる商品である。 “Multiple products” are products handled in the electronic market.
　区間とは、ショップや電子市場の管理者等が、商品の各メーカが規定したサイズを基に指定する商品サイズの範囲である。 A section is a product size range specified by a shop or electronic market manager based on the size specified by each product manufacturer.
　本実施形態では、商品は、衣類とし、区間は、身長についてのサイズ範囲として説明する。例えば、衣類の場合、各メーカが規定したサイズについては、そのサイズの着用に適している想定身長や想定ウェスト等が設けられている。区間は、この想定身長等に基づいて定める。 In the present embodiment, the commodity is described as clothing, and the section is described as a size range for height. For example, in the case of clothing, for a size specified by each manufacturer, an assumed height and an assumed waist that are suitable for wearing the size are provided. The section is determined based on the assumed height.
　例えば、あるメーカＰが規定するサイズＳ、Ｍ、Ｌの想定身長は、それぞれ、１５５ｃｍ～１６５ｃｍ、１６５ｃｍ～１７５ｃｍ、１７５ｃｍ～１８５ｃｍである。一方、他のメーカＱが規定するサイズＳ、Ｍ、Ｌの想定身長は、それぞれ、１６０ｃｍ～１７０ｃｍ、１６５ｃｍ～１７５ｃｍ、１７０ｃｍ～１８０ｃｍである。この場合、Ｓ及びＬサイズは、同じサイズであっても想定身長は一致しないので、例えば、メーカＰ及びＱでＳサイズの商品を購入したとしても、メーカＰの商品はショッパーのサイズと合っているが、メーカＱの商品はショッパーのサイズに合っていないということがある。また、ＭサイズのようにメーカＰ及びＱの想定身長が一致していても、例えば、メーカＰはゆとりを持って商品を作成する傾向があり、メーカＱは、ゆとりを持たせないように商品を作成する傾向がある場合、ショッパーが実際に着た時に感じるフィット感は異なっていることがある。 For example, the assumed heights of sizes S, M, and L specified by a certain manufacturer P are 155 cm to 165 cm, 165 cm to 175 cm, and 175 cm to 185 cm, respectively. On the other hand, the assumed heights of sizes S, M, and L specified by other manufacturers Q are 160 cm to 170 cm, 165 cm to 175 cm, and 170 cm to 180 cm, respectively. In this case, the assumed height does not match even if the S and L sizes are the same size. For example, even if the S size product is purchased by the manufacturer P and Q, the product of the manufacturer P matches the size of the shopper. However, there are cases where the product of manufacturer Q does not match the size of the shopper. Also, even if the assumed heights of manufacturers P and Q are the same as in the M size, for example, manufacturer P tends to create products with a margin, and manufacturer Q has a product that does not have a margin. If you tend to create a shopper, the fit that you feel when you actually wear it may be different.
　このように、メーカが想定しているサイズは、ショッパーの印象とは一致していないことがあるので、各区間の初期設定の際には、サイズの幅には余裕を持たせ、隣接するサイズが重複するように設定し、調節可能な幅を広く設けておく。例えば、メーカＰのＳ、Ｍ、Ｌについては、それぞれの区間を、１５０ｃｍ～１７０ｃｍ、１６０ｃｍ～１８０ｃｍ、１７０ｃｍ～１９０ｃｍのように設定し、メーカＱのＳ、Ｍ、Ｌについては、それぞれの区間を、１５５ｃｍ～１７５ｃｍ、１６０ｃｍ～１８０ｃｍ、１６５ｃｍ～１８５ｃｍのように設定する。 In this way, the size assumed by the manufacturer may not match the shopper's impression, so when initializing each section, leave a margin for the size and set the adjacent size. Are set to overlap, and a wide adjustable range is provided. For example, for S, M, and L of manufacturer P, the respective sections are set to 150 cm to 170 cm, 160 cm to 180 cm, and 170 cm to 190 cm, and for S, M, and L of manufacturer Q, the respective sections are set. 155 cm to 175 cm, 160 cm to 180 cm, and 165 cm to 185 cm.
　例えば、記憶部１０１には、図４に示すような商品区間テーブル１０１ａが格納されている。商品区間テーブル１０１ａには、電子市場の商品を識別するための商品ＩＤ　１０１ａ１と、当該商品の区間１０１ａ２と、が対応付けて登録されている。図４の商品区間テーブル１０１ａの１行目は、商品ＩＤが「Ａ」の商品が対象とするショッパーの身長の区間が「１５０ｃｍ～１７０ｃｍ」であることを示す。 For example, the storage section 101 stores a product section table 101a as shown in FIG. In the product section table 101a, a product ID 101a1 for identifying a product in the electronic market and a section 101a2 of the product are registered in association with each other. The first line of the product section table 101a in FIG. 4 indicates that the height section of the shopper targeted by the product with the product ID “A” is “150 cm to 170 cm”.
　受付部１０２は、ショッパーより、当該ショッパーが購入した商品の中から、下限商品と上限商品とが指定された要求を受け付ける。 The accepting unit 102 accepts a request from the shopper in which the lower limit product and the upper limit product are designated from among the products purchased by the shopper.
　下限商品とは、ショッパーが購入した商品であり、ショッパーがこの商品以上に大きい商品を検索することを要求する場合に指定される商品である。 The lower limit product is a product purchased by the shopper and is a product designated when the shopper requests to search for a product larger than this product.
　上限商品とは、ショッパーが購入した商品であり、ショッパーがこの商品以下に小さい商品を検索することを要求する場合に指定される商品である。 The upper limit product is a product purchased by a shopper, and is a product specified when the shopper requests to search for a product smaller than this product.
　例えば、図５に示すような検索ページ５００がショッパーＸのショッパー端末２００の画面に表示されているとする。ショッパーＸは、検索語を「シャツ」として検索し、この検索結果を絞り込むために、下限商品及び上限商品を指定する。ボックス５０１のプルダウンをクリックすると、ショッパーＸが過去に購入した商品のリストが表示され、この中から商品を選択すると、ボックス５０１に選択した商品名「商品Ａ」が表示される。同様に、ボックス５０２のプルダウンをクリックして過去に購入した商品の中から商品を選択すると、ボックス５０２に商品名「商品Ｂ」が表示される。そして、絞込みを要求するボタン５０３をクリックすると、ショッパー装置２００から、下限商品に「商品Ａ」、上限商品に「商品Ｂ」が指定された絞込み要求が送信され、受付部１０２は、この絞込み要求を受信する。 For example, assume that a search page 500 as shown in FIG. 5 is displayed on the screen of the shopper terminal 200 of the shopper X. The shopper X searches the search term as “shirt”, and specifies the lower limit product and the upper limit product in order to narrow down the search result. When the pull-down box 501 is clicked, a list of products purchased by the shopper X in the past is displayed. When a product is selected from the list, the selected product name “product A” is displayed in the box 501. Similarly, when a product is selected from products purchased in the past by clicking on the pull-down box 502, the product name “product B” is displayed in the box 502. When the button 503 for requesting narrowing is clicked, the shopper device 200 transmits a narrowing request in which “product A” is designated as the lower limit product and “product B” is designated as the upper limit product. Receive.
　なお、下限商品及び上限商品の指定の態様は上記に限らず、例えば、検索語を記入するボックス５０４に「商品Ａ以上に大きく商品Ｂ以上に小さい」のような文言を記入させ、この文言を解析して下限商品及び上限商品を特定するようにしてもよい。 The specification mode of the lower limit product and the upper limit product is not limited to the above. For example, in the box 504 for entering a search term, a word such as “larger than product A and smaller than product B” is entered, and this wording is changed. The lower limit product and the upper limit product may be specified by analysis.
　取得部１０３は、記憶部１０１から、下限商品に対応付けられた区間を第１下限区間とし、上限商品に対応付けられた区間を第１上限区間として取得し、第１下限区間の下限値及び第１上限区間の上限値を、それぞれ下限値及び上限値とする第１検索区間を求める。 The acquisition unit 103 acquires, from the storage unit 101, the section associated with the lower limit product as the first lower limit section, the section associated with the upper limit product as the first upper limit section, and the lower limit value of the first lower limit section and A first search section is obtained with the upper limit value of the first upper limit section as the lower limit value and the upper limit value, respectively.
　第１下限区間とは、下限商品に対応付けられた区間である。また、第１上限区間とは、上限商品に対応付けられた区間である。 The first lower limit section is a section associated with the lower limit product. The first upper limit section is a section associated with the upper limit product.
　例えば、取得部１０３は、図４の商品区間テーブル１０１ａを参照して、下限商品の「商品Ａ」の区間「１５０ｃｍ～１７０ｃｍ」を第１下限区間として取得し、上限商品の「商品Ｂ」の区間「１５５ｃｍ～１７５ｃｍ」を第１上限区間として取得する。そして、第１下限区間の下限値「１５０ｃｍ」を下限値とし、第１上限区間の上限値「１７５ｃｍ」を上限値とする、第１検索区間「１５０ｃｍ～１７５ｃｍ」を求める。 For example, referring to the product section table 101a of FIG. 4, the acquisition unit 103 acquires the section “150 cm to 170 cm” of the “product A” of the lower limit product as the first lower limit section, and sets the “commodity B” of the upper limit product. The section “155 cm to 175 cm” is acquired as the first upper limit section. Then, a first search section “150 cm to 175 cm” is obtained in which the lower limit value “150 cm” of the first lower limit section is set as the lower limit value and the upper limit value “175 cm” of the first upper limit section is set as the upper limit value.
　検索部１０４は、第１検索区間と重複する区間が対応付けられた商品を、記憶部１０１から検索する。 The search unit 104 searches the storage unit 101 for a product associated with a section that overlaps the first search section.
　例えば、検索部１０４は、図４の商品区間テーブル１０１ａの区間１０１ａ２を参照して、第１検索区間「１５０ｃｍ～１７５ｃｍ」と重複する区間を有する商品を選択する。例えば、商品Ｃの区間「１６０ｃｍ～１８０ｃｍ」は一部区間が重なるので、検索部１０４は、商品Ｃを選択する。同様に、商品Ｄ、商品Ｅも選択される。 For example, the search unit 104 refers to the section 101a2 of the product section table 101a in FIG. 4 and selects a product having a section overlapping with the first search section “150 cm to 175 cm”. For example, since the sections “160 cm to 180 cm” of the product C partially overlap, the search unit 104 selects the product C. Similarly, the product D and the product E are also selected.
　なお、検索部１０４は、第１検索区間と重複する区間が対応付けられた商品ではなく、第１検索区間に含まれる区間が対応付けられた商品を選択するようにしてもよい。例えば、第１検索区間に対応付けられた区間が含まれる商品Ｄは選択されるが、第１検索区間に含まれない区間を有する商品Ｃ、商品Ｅは選択されない。 Note that the search unit 104 may select a product associated with a section included in the first search section instead of a product associated with a section overlapping with the first search section. For example, the product D including the section associated with the first search section is selected, but the product C and the product E having sections not included in the first search section are not selected.
　提示部１０５は、第１検索区間と重複する区間が対応付けられた商品をショッパーに提示する。 The presenting unit 105 presents to the shopper a product associated with a section that overlaps the first search section.
　例えば、提示部１０５は、検索ページ５００の検索結果５０５を、検索部１０４により選択された商品のみが含まれるよう更新する。 For example, the presentation unit 105 updates the search result 505 of the search page 500 so that only the product selected by the search unit 104 is included.
　更新部１０６は、第１検索区間と重複する区間が対応付けられた商品が記憶部１０１に記憶され、第１下限区間と第１上限区間とが重複する場合、第１下限区間と第１上限区間との重複区間が小さくなるように、記憶部１０１に記憶された第１下限区間の上限値を減少させた値に更新し、記憶部１０１に記憶された第１上限区間の下限値を増加させた値に更新する。 The update unit 106 stores, in the storage unit 101, a product in which a section overlapping with the first search section is associated, and when the first lower limit section and the first upper limit section overlap, the first lower limit section and the first upper limit section The upper limit value of the first lower limit section stored in the storage unit 101 is updated to a value that is decreased, and the lower limit value of the first upper limit section stored in the storage unit 101 is increased so that the overlapping section with the section becomes smaller. Update to the value that was set.
　図６は、第１検索区間と重複区間との関係を示す図である。図６において、重複区間（区間７０４）は、第１下限区間（区間７０１）と第１上限区間（区間７０２）の重複する区間であり、第１検索区間（区間７０３）に含まれる区間である。 FIG. 6 is a diagram showing the relationship between the first search section and the overlapping section. In FIG. 6, an overlapping section (section 704) is a section where the first lower limit section (section 701) and the first upper limit section (section 702) overlap and is included in the first search section (section 703). .
　第１検索区間と重複する区間が対応付けられた商品が記憶部１０１に記憶されているということは、第１検索区間に誤りがないということを示し、すなわち、ショッパーＸが下した、「商品Ａ」よりも「商品Ｂ」の方が大きい、との判断に誤りがないことを示す。もし、ショッパーＸの下限商品を「商品Ｅ」、上限商品を「商品Ａ」のように指定すれば、第１検索区間として、下限値が「１７１ｃｍ」で上限値が「１７０ｃｍ」という誤った区間が設定され、このような第１検索区間と重複する区間を有する商品は存在しない。よって、第１検索区間と重複する区間が対応付けられた商品が記憶部１０１に記憶されていれば、ショッパーの示した大小関係が信頼できると判断する。 The fact that the product associated with the section that overlaps the first search section is stored in the storage unit 101 indicates that there is no error in the first search section. This indicates that there is no error in determining that “product B” is larger than “A”. If the lower limit product of shopper X is specified as “product E” and the upper limit product is specified as “product A”, the first search section is an erroneous section where the lower limit value is “171 cm” and the upper limit value is “170 cm”. Is set, and there is no product having such a section that overlaps the first search section. Therefore, if a product associated with a section that overlaps the first search section is stored in the storage unit 101, it is determined that the magnitude relationship indicated by the shopper is reliable.
　更新部１０６は、ショッパーＸによる「商品Ａ」よりも「商品Ｂ」の方が大きい、との判断に基づいて、商品Ａに対応付けられた区間と、商品Ｂに対応付けられた区間との差を明確にするために、重複区間が小さくなるよう変更する。 Based on the determination that “product B” is larger than “product A” by shopper X, the update unit 106 determines whether the section associated with product A and the section associated with product B are the same. In order to clarify the difference, the overlap interval is changed to be small.
　例えば、第１検索区間「１５０ｃｍ～１７５ｃｍ」（区間７０３）と重複する区間が対応付けられた商品が図４の商品区間テーブル１０１ａに登録され、第１下限区間「１５０ｃｍ～１７０ｃｍ」（区間７０１）と、第１上限区間「１５５ｃｍ～１７５ｃｍ」（区間７０２）とは重複区間（区間７０４）があるので、更新部１０６は、区間７０４がより小さい区間になるよう、区間７０１の上限値「１７０ｃｍ」と、区間７０２の下限値「１５５ｃｍ」を変更する。 For example, a product associated with a section that overlaps the first search section “150 cm to 175 cm” (section 703) is registered in the product section table 101a of FIG. 4, and the first lower limit section “150 cm to 170 cm” (section 701). Since the first upper limit section “155 cm to 175 cm” (section 702) has an overlapping section (section 704), the update unit 106 sets the upper limit value “170 cm” of the section 701 so that the section 704 becomes a smaller section. Then, the lower limit value “155 cm” of the section 702 is changed.
　ここで、更新部１０６は、重複区間が、当該重複区間の長さに１未満の数を乗じた長さとなるよう、第１下限区間の上限値と、第１上限区間の下限値と、を調整する。 Here, the update unit 106 calculates the upper limit value of the first lower limit section and the lower limit value of the first upper limit section so that the overlap section has a length obtained by multiplying the length of the overlap section by a number less than 1. adjust.
　例えば、重複区間（区間７０４）の長さは「１５ｃｍ」であり、この値に定数「０．８」を乗じた値「１２ｃｍ」を新たな重複区間の長さとする。この定数を、大きくすれば調整量は小さくなり、小さくすれば調整量は大きくなる。更新部１０６は、重複区間の長さが「１２ｃｍ」となるよう、区間７０１の上限値「１７０ｃｍ」を「１６８．５ｃｍ」に変更し、区間７０２の下限値「１５５ｃｍ」を「１５６．５ｃｍ」に変更する。そして、更新部１０６は、それぞれ変更した第１下限区間「１５０ｃｍ～１６８．５ｃｍ」（区間７０５）及び第１上限区間「１５６．５ｃｍ～１７５ｃｍ」（区間７０６）を、商品区間テーブル１０１ａに登録する（図７）。 For example, the length of the overlapping section (section 704) is “15 cm”, and a value “12 cm” obtained by multiplying this value by a constant “0.8” is set as the length of the new overlapping section. Increasing this constant decreases the adjustment amount, and decreasing it increases the adjustment amount. The updating unit 106 changes the upper limit value “170 cm” of the section 701 to “168.5 cm” and sets the lower limit value “155 cm” of the section 702 to “156.5 cm” so that the length of the overlapping section becomes “12 cm”. Change to Then, the update unit 106 registers the changed first lower limit section “150 cm to 168.5 cm” (section 705) and first upper limit section “156.5 cm to 175 cm” (section 706) in the product section table 101a. (FIG. 7).
　なお、第１下限区間の上限値の減少幅、及び、第１上限区間の下限値の増加幅は、任意に決定することができる。例えば、上記の例では、下限値の減少幅及び上限値の増加幅は「１．５ｃｍ」で同じであるが、異なっていてもよい。また、上記のように、重複区間に１未満の定数を乗じるのではなく、更新部１０６が、条件を満たすと判断したら、第１下限区間の上限値を「１ｃｍ」減少させ、第１上限区間の下限値を「１ｃｍ」増加させる、というように所定の値だけ変更するようにしてもよい。 In addition, the decreasing range of the upper limit value of the first lower limit section and the increasing range of the lower limit value of the first upper limit section can be arbitrarily determined. For example, in the above example, the decrease width of the lower limit value and the increase width of the upper limit value are the same at “1.5 cm”, but may be different. In addition, as described above, instead of multiplying the overlapping section by a constant less than 1, if the update unit 106 determines that the condition is satisfied, the upper limit value of the first lower limit section is decreased by “1 cm” and the first upper limit section is decreased. The lower limit value may be changed by a predetermined value, for example, “1 cm” is increased.
　通常、商品のサイズについては各メーカがそれぞれ指定するが、指定されたサイズが一致するからといって、必ずしも同じ大きさであるとは限らない。例えば、衣類であれば、同じＭサイズを示していても、メーカごとにゆったり目あるいはぴったり目など、大きさの傾向に違いがある場合がある。このようにメーカごとに異なる実際の大きさのばらつきを考慮して商品の大小関係を求めるのは、商品数や実際に計測する手間などから、困難であった。しかし、本実施形態によれば、実際に購入したショッパーが示した大小関係を利用することができ、これに基づいて、商品の区間を調節することができる。そして、商品同士の大小関係を多数のショッパーが入力すれば、それだけ、各商品の下限値及び上限値が調整される回数が増える。商品に対応付けられる区間は、このような調整を繰り返すことにより、多数のショッパーの印象を反映した商品の大小関係を求めることができる。 Normally, each manufacturer specifies the product size, but just because the specified sizes match does not necessarily mean they are the same size. For example, in the case of clothing, even if the same M size is shown, there may be a difference in the size tendency such as loose eyes or perfect eyes for each manufacturer. In this way, it is difficult to obtain the size relationship between products in consideration of the variation in actual size that varies from manufacturer to manufacturer because of the number of products and the time and effort of actual measurement. However, according to the present embodiment, the size relationship indicated by the actually purchased shopper can be used, and the section of the product can be adjusted based on this. And if many shoppers input the magnitude relationship between goods, the frequency | count that the lower limit and upper limit of each goods will be adjusted will increase by that much. The section associated with the product can obtain the magnitude relation of the product reflecting the impressions of many shoppers by repeating such adjustment.
　また、ショッパーが実際に商品を購入した後に、購入商品の大きさについてフィードバックを求めても、面倒と受け取られて、フィードバックが得られないことがある。しかし、ショッパーが商品の検索をするときに、購入履歴を利用して、検索対象の商品を絞り込むことは、ショッパーの負担も軽い。そして、ショッパーは実感に基づく大きさの絞り込みを行うことができるので、ショッパーにとっても利点がある。このように、本実施形態によれば、ショッパーに煩わしさを感じさせることなく、ショッパーによる商品の大小関係についての判断を利用することができる。 Also, after a shopper actually purchases a product, even if he asks for feedback on the size of the purchased product, it may be regarded as troublesome and feedback may not be obtained. However, when a shopper searches for a product, using the purchase history to narrow down the products to be searched reduces the burden on the shopper. And since a shopper can narrow down the magnitude | size based on actual feeling, there exists an advantage also for a shopper. As described above, according to the present embodiment, it is possible to use the shopper's judgment about the size relationship of the product without making the shopper feel bothersome.
　また、受付部１０２が、要求に指定された下限商品及び上限商品が指定された他の要求を、所定数以上の他のショッパーから受け付けると、更新部１０６は、重複区間が無くなるように、第１下限区間の上限値を減少させた値に更新し、第１上限区間の下限値を増加させた値に更新するようにしてもよい。 In addition, when the receiving unit 102 receives another request in which the lower limit product and the upper limit product specified in the request are specified from another predetermined number or more of other shoppers, the updating unit 106 is configured to eliminate the overlapping section. The upper limit value of the first lower limit section may be updated to a value that is decreased, and the lower limit value of the first upper limit section may be updated to a value that is increased.
　例えば、ショッパーＸが、下限商品を「商品Ａ」、上限商品を「商品Ｂ」と指定して商品の絞込みを行い、同じように、下限商品を「商品Ａ」、上限商品を「商品Ｂ」と指定して絞込みを行ったショッパーがショッパーＸ以外に多数存在する場合、「商品Ａ」よりも「商品Ｂ」の方が明らかに大きいと判断して、重複区間が無くなるようにそれぞれの商品の区間を更新する。例えば、更新部１０６は、「商品Ａ」の区間を、「１５０ｃｍ～１６２．５ｃｍ」と、「商品Ｂ」の区間を、「１６２．５ｃｍ～１７５ｃｍ」と更新する。 For example, shopper X designates the lower limit product as “product A” and the upper limit product as “product B”, and narrows down the products. Similarly, the lower limit product is “product A” and the upper limit product is “product B”. If there are many shoppers other than shopper X that have been specified, it is determined that “product B” is clearly larger than “product A”, so that there are no overlapping sections. Update the interval. For example, the updating unit 106 updates the section “product A” to “150 cm to 162.5 cm” and the section “product B” to “162.5 cm to 175 cm”.
　なお、所定数は、ショッパーによる商品の大小関係の認定が十分信頼できると判断できる数とし、検索装置１００の管理者が適宜設定できる。 It should be noted that the predetermined number is a number by which it can be determined that the shopper can sufficiently trust the authorization of the product size, and can be appropriately set by the administrator of the search device 100.
　このような構成により、多数のショッパーの大小関係に関する印象を反映して、商品区間の差を明確に設定することができる。 構成 With such a configuration, it is possible to clearly set the difference between the product sections, reflecting the impression of the size relationship of a large number of shoppers.
　また、要求にかかる下限商品及び上限商品から取得した第１下限区間及び第１上限区間に基づいて求めた第１検索区間と重複する区間が対応付けられた商品が記憶部１０１に記憶され、第１下限区間と第１上限区間とが重複する場合、記憶部１０１は、要求を記憶する。 In addition, a product associated with a first search section obtained based on the first lower limit section and the first upper limit section acquired from the lower limit product and the upper limit product according to the request is stored in the storage unit 101, When the 1 lower limit section and the first upper limit section overlap, the storage unit 101 stores the request.
　例えば、記憶部１０１には、図８に示すような要求履歴テーブル１０１ｂが格納されている。要求履歴テーブル１０１ｂには、受け付けた要求を識別するための要求ＩＤ　１０１ｂ１と、当該要求に指定された下限商品を識別するための下限商品ＩＤ　１０１ｂ２と、当該下限商品に対応付けられた第１下限区間１０１ｂ３と、当該要求に指定された上限商品を識別するための上限商品ＩＤ　１０１ｂ４と、当該上限商品に対応付けられた第１上限区間１０１ｂ５と、が対応付けて登録されている。図８の要求履歴テーブル１０１ｂの１行目は、要求ＩＤが「１」の要求に指定された下限商品が「商品Ａ」、上限商品が「商品Ｂ」であり、第１下限区間が「１５０ｃｍ～１７０ｃｍ」、第１上限区間が「１５５ｃｍ～１７５ｃｍ」であることを示す。 For example, the storage unit 101 stores a request history table 101b as shown in FIG. The request history table 101b includes a request ID 101b1 for identifying the received request, a lower limit product ID 101b2 for identifying the lower limit product specified in the request, and a first lower limit associated with the lower limit product. The section 101b3, the upper limit product ID 101b4 for identifying the upper limit product specified in the request, and the first upper limit section 101b5 associated with the upper limit product are registered in association with each other. The first line of the request history table 101b in FIG. 8 indicates that the lower limit product specified in the request with the request ID “1” is “product A”, the upper limit product is “product B”, and the first lower limit section is “150 cm”. ˜170 cm ”and the first upper limit section is“ 155 cm to 175 cm ”.
　例えば、下限商品を「商品Ａ」、上限商品を「商品Ｂ」と指定された要求を受け付けた場合、受け付けた下限商品及び上限商品に基づいて求めた第１検索区間「１５０ｃｍ～１７５ｃｍ」と重複する区間を有する商品が図４の商品区間テーブル１０１ａに登録され、第１下限区間「１５０ｃｍ～１７０ｃｍ」と、第１上限区間「１５５ｃｍ～１７５ｃｍ」とは重複区間があるので、更新部１０６は、要求を識別するためのＩＤを付して、要求に指定された下限商品及び上限商品と、それらから求めた第１下限区間及び第１上限区間と、を対応付けて要求履歴テーブル１０１ｂに登録する。 For example, if a request with the lower limit product specified as “product A” and the upper limit product as “product B” is received, it overlaps with the first search section “150 cm to 175 cm” obtained based on the received lower limit product and upper limit product. The product having the section to be registered is registered in the product section table 101a of FIG. 4, and the first lower limit section “150 cm to 170 cm” and the first upper limit section “155 cm to 175 cm” have overlapping sections. An ID for identifying the request is attached, and the lower limit product and the upper limit product specified in the request, and the first lower limit section and the first upper limit section obtained from them are associated and registered in the request history table 101b. .
　そして、更新部１０６は、記憶された要求に係る第１下限区間及び第１上限区間の組み合わせの数に従い、第１下限区間の上限値及び第１上限区間の下限値を調節する。 Then, the update unit 106 adjusts the upper limit value of the first lower limit section and the lower limit value of the first upper limit section according to the number of combinations of the first lower limit section and the first upper limit section related to the stored request.
　例えば、図８の要求履歴テーブル１０１ｂには、「商品Ａ」を下限商品、「商品Ｂ」を上限商品と指定した要求が多数（例えば、１０個）登録されており、「商品Ｂ」を下限商品、「商品Ａ」を上限商品と指定した要求が、１つだけ登録されているとする。この場合、次に、「商品Ｂ」を下限商品、「商品Ａ」を上限商品と指定した要求を受け付けると、更新部１０６は、更新の条件を満たしていたとしても、「商品Ｂ」の第１下限区間「１５５ｃｍ～１７５ｃｍ」の上限値「１７５ｃｍ」を減少させず、「商品Ａ」の第１上限区間「１５０ｃｍ～１７０ｃｍ」の下限値「１５０ｃｍ」を増加させない。 For example, in the request history table 101b of FIG. 8, a large number (for example, 10) of requests specifying “product A” as the lower limit product and “product B” as the upper limit product are registered, and “product B” is set as the lower limit. It is assumed that only one request that designates the product, “product A”, as the upper limit product is registered. In this case, when receiving a request that designates “product B” as the lower limit product and “product A” as the upper limit product, the update unit 106 determines whether the “product B” The upper limit value “175 cm” of the first lower limit section “155 cm to 175 cm” is not decreased, and the lower limit value “150 cm” of the first upper limit section “150 cm to 170 cm” of “product A” is not increased.
　あるいは、記憶された要求の数に比例させるように、上限値及び下限値を調節するようにしてもよい。例えば、「商品Ａ」を下限商品、「商品Ｂ」を上限商品と指定した要求を受け付けた場合は、要求履歴テーブル１０１ｂに同じ内容の要求は１０個登録されているので、第１下限区間の上限値の減少幅を「２ｃｍ」、第１上限区間の下限値の増加幅を「２ｃｍ」とする。一方、「商品Ｂ」を下限商品、「商品Ａ」を上限商品と指定した要求を受け付けた場合は、要求履歴テーブル１０１ｂに同じ内容の要求は１個登録されているので、第１下限区間の上限値の減少幅を「０．２ｃｍ」、第１上限区間の下限値の増加幅を「０．２ｃｍ」とする。 Alternatively, the upper limit value and the lower limit value may be adjusted so as to be proportional to the number of stored requests. For example, if a request specifying “product A” as the lower limit product and “product B” as the upper limit product is received, ten requests having the same contents are registered in the request history table 101b. The decrease width of the upper limit value is “2 cm”, and the increase width of the lower limit value of the first upper limit section is “2 cm”. On the other hand, when a request specifying “product B” as the lower limit product and “product A” as the upper limit product is received, one request having the same content is registered in the request history table 101b. The decrease width of the upper limit value is “0.2 cm”, and the increase width of the lower limit value of the first upper limit section is “0.2 cm”.
　ショッパーによる商品の大小に関する印象は、感じ方に個人差があるので、必ずしも実際の大きさに対応しているわけではない。したがって、大多数のショッパーと異なる判断を示すショッパーも存在する。しかし、このような構成により、できるだけ多くのショッパーの判断に基づいた区間の調整を行うことができる。 The impression of the size of the product by the shopper does not necessarily correspond to the actual size because there are individual differences in how it is felt. Therefore, there are shoppers that show different judgments from the majority of shoppers. However, with such a configuration, it is possible to adjust the section based on the judgment of as many shoppers as possible.
　また、以下に示すように、要求に指定された下限商品及び上限商品を入れ替えて検索することにより、ショッパーの指定した下限商品及び上限商品の誤りを検出するようにしてもよい。 Also, as shown below, an error in the lower limit product and upper limit product specified by the shopper may be detected by searching the lower limit product and the upper limit product specified in the request.
　取得部１０３は、下限商品に対応付けられた区間を第２上限区間とし、上限商品に対応付けられた区間を第２下限区間とし、第２上限区間の上限値及び第２下限区間の下限値をそれぞれ上限値及び下限値とする第２検索区間を求める。 The acquisition unit 103 sets the section associated with the lower limit product as the second upper limit section, sets the section associated with the upper limit product as the second lower limit section, and sets the upper limit value of the second upper limit section and the lower limit value of the second lower limit section. Are obtained as the upper limit value and the lower limit value, respectively.
　以下、図９を参照して説明する。例えば、受付部１０２が、ショッパーＹから下限商品を「商品Ｃ」、上限商品を「商品Ａ」と指定して絞り込み要求を受け付けた場合、取得部１０３は、まず、第１下限区間を「１６０ｃｍ～１８０ｃｍ」（区間８０１）、第１上限区間を「１５０ｃｍ～１７０ｃｍ」（区間８０２）、第１検索区間を「１６０ｃｍ～１７０ｃｍ」（区間８０３）と求める。そして、取得部１０３は、さらに、第２下限区間を「１５０ｃｍ～１７０ｃｍ」（区間８０２）、第２上限区間を「１６０ｃｍ～１８０ｃｍ」（区間８０１）、第２検索区間を「１５０ｃｍ～１８０ｃｍ」（区間８０４）と求める。 Hereinafter, description will be given with reference to FIG. For example, when the receiving unit 102 receives a narrowing request from the shopper Y by designating the lower limit product as “product C” and the upper limit product as “product A”, the acquisition unit 103 first sets the first lower limit section to “160 cm. ˜180 cm ”(section 801), the first upper limit section is obtained as“ 150 cm to 170 cm ”(section 802), and the first search section is obtained as“ 160 cm to 170 cm ”(section 803). Further, the acquisition unit 103 further sets the second lower limit section to “150 cm to 170 cm” (section 802), the second upper limit section to “160 cm to 180 cm” (section 801), and the second search section to “150 cm to 180 cm” (section 802). Section 804) is obtained.
　検索部１０４は、第２検索区間と重複する区間が対応付けられた商品を、記憶部１０１から検索する。 The search unit 104 searches the storage unit 101 for a product associated with a section that overlaps the second search section.
　例えば、検索部１０４は、図４の商品区間テーブル１０１ａの区間１０１ａ２を参照して、第１検索区間「１６０ｃｍ～１７０ｃｍ」と重複する商品を選択し、さらに、第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する商品を選択する。 For example, the search unit 104 refers to the section 101a2 of the product section table 101a of FIG. 4, selects a product that overlaps the first search section “160 cm to 170 cm”, and further selects the second search section “150 cm to 180 cm”. Select the products that overlap.
　提示部１０５は、第１検索区間と重複する区間が対応付けられた商品の数が、第２検索区間と重複する区間が対応付けられた商品の数と比較して、所定の比較基準より小さければ、第２検索区間と重複する区間が対応付けられた商品を、ショッパーに提示する。 The presenting unit 105 determines that the number of products associated with a section overlapping with the first search section is smaller than a predetermined comparison criterion compared with the number of products associated with a section overlapping with the second search section. For example, a product in which a section overlapping with the second search section is associated is presented to the shopper.
　所定の比較基準とは、２つの数の大きさの差がどの程度であるかを示すものである。本実施形態では、一方の数が、この基準より小さければ、他方の数より十分小さいと見なす。 The predetermined comparison standard indicates how much the difference between the two numbers is. In the present embodiment, if one number is smaller than this reference, it is considered to be sufficiently smaller than the other number.
　例えば、所定の比較基準を、「一方の数が他方の数の１０分の１」とする。第１検索区間「１６０ｃｍ～１７０ｃｍ」と重複する区間を有する商品の数が「９０」、第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する区間を有する商品の数が「１２００」の場合、提示部１０５は、第１検索区間と重複する区間が対応付けられた商品の数が、第２検索区間と重複する区間が対応付けられた商品の数と比較して、所定の比較基準より小さいと判断し、第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する区間が対応付けられた商品をショッパーＹに提示する。なお、所定の比較基準は、「一方の数が１００個以下、他方の数が１０００以上」のように設定してもよい。 For example, the predetermined comparison criterion is “one number is one tenth of the other number”. When the number of products having a section overlapping with the first search section “160 cm to 170 cm” is “90” and the number of products having a section overlapping with the second search section “150 cm to 180 cm” is “1200”, the presentation unit 105 determines that the number of products associated with a section overlapping with the first search section is smaller than a predetermined comparison criterion compared to the number of products associated with a section overlapping with the second search section. Then, the merchandise associated with the second search section “150 cm to 180 cm” and the overlapping section is presented to the shopper Y. The predetermined comparison criterion may be set such that “one number is 100 or less and the other number is 1000 or more”.
　そして、更新部１０６は、第１検索区間と重複する区間が対応付けられた商品の数が、第２検索区間と重複する区間が対応付けられた商品の数と比較して、所定の比較基準より小さく、第２下限区間と第２上限区間とが重複する場合、第２下限区間と第２上限区間との重複区間が小さくなるように、記憶部１０１に記憶された第２下限区間の上限値を減少させた値に更新し、記憶部１０１に記憶された第２上限区間の下限値を増加させた値に更新する。 Then, the update unit 106 compares the number of products associated with the section overlapping with the first search section with the number of products associated with the section overlapped with the second search section, and determines a predetermined comparison criterion. If the second lower limit interval and the second upper limit interval overlap with each other, the upper limit of the second lower limit interval stored in the storage unit 101 is reduced so that the overlap interval between the second lower limit interval and the second upper limit interval becomes smaller. The value is updated to the decreased value, and the lower limit value of the second upper limit section stored in the storage unit 101 is updated to the increased value.
　例えば、第１検索区間「１６０ｃｍ～１７０ｃｍ」と重複する区間を有する商品の数「９０」が第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する区間を有する商品の数「１２００」と比較して、１０分の１より小さく、第２下限区間「１５０ｃｍ～１７０ｃｍ」（区間８０２）と第２上限区間「１６０ｃｍ～１８０ｃｍ」（区間８０１）とは重複区間（区間８０３）があるので、更新部１０６は、第２下限区間の上限値「１７０ｃｍ」を「１６８ｃｍ」に更新し、第２上限区間の下限値「１６０ｃｍ」を「１６２ｃｍ」に更新する。 For example, the number “90” of products having a section overlapping with the first search section “160 cm to 170 cm” is compared with the number “1200” of products having a section overlapping with the second search section “150 cm to 180 cm”. Since the second lower limit section “150 cm to 170 cm” (section 802) and the second upper limit section “160 cm to 180 cm” (section 801) have an overlapping section (section 803), the update unit 106 is smaller than 1/10. The upper limit value “170 cm” of the second lower limit section is updated to “168 cm”, and the lower limit value “160 cm” of the second upper limit section is updated to “162 cm”.
　指定された下限商品の区間と上限商品の区間とを入れ替えて、検索結果に含まれる商品の数の大きさが大幅に増加した場合、指定した下限商品と上限商品との大小関係が誤っていると考えられる。このような構成によれば、検索結果の数を利用して、ショッパーの入力誤りを検出し、正しい区間に基づいた検索結果を提示し、区間の調整を行うことができる。 If the size of the number of products included in the search results increases significantly when the specified lower limit product section and the upper limit product section are swapped, the magnitude relationship between the specified lower limit product and the upper limit product is incorrect. it is conceivable that. According to such a configuration, by using the number of search results, it is possible to detect a shopper input error, present a search result based on the correct section, and adjust the section.
（４．実施形態の検索装置の動作）
　本実施形態の検索装置が行う動作について説明する。検索装置は、例えば、電源が投入されると、図１０に示す検索処理を開始する。 (4. Operation of search device of embodiment)
The operation | movement which the search device of this embodiment performs is demonstrated. For example, when the power is turned on, the search device starts the search process shown in FIG.
　受付部１０２は、ショッパーより、当該ショッパーが購入した商品の中から、下限商品と上限商品とが指定された要求を受け付ける（ステップＳ１０１）。受付部１０２が、ショッパーより上記要求を受け付けたと判断すると（ステップＳ１０１；Ｙｅｓ）、取得部１０３は、記憶部１０１から、下限商品に対応付けられた区間を第１下限区間とし、上限商品に対応付けられた区間を第１上限区間として取得し、第１下限区間の下限値及び第１上限区間の上限値を、それぞれ下限値及び上限値とする第１検索区間を求め、さらに、下限商品に対応付けられた区間を第２上限区間とし、上限商品に対応付けられた区間を第２下限区間とし、第２上限区間の上限値及び第２下限区間の下限値をそれぞれ上限値及び下限値とする第２検索区間を求める（ステップＳ１０２）。一方、受付部１０２が、上記要求を受け付けていないと判断すると（ステップＳ１０１；Ｎｏ）、そのまま待機する。 The accepting unit 102 accepts, from the shopper, a request in which the lower limit product and the upper limit product are specified from among the products purchased by the shopper (step S101). When the receiving unit 102 determines that the request has been received from the shopper (step S101; Yes), the acquiring unit 103 sets the section associated with the lower limit product as the first lower limit section from the storage unit 101, and corresponds to the upper limit product. The attached section is acquired as a first upper limit section, a first search section is obtained with the lower limit value of the first lower limit section and the upper limit value of the first upper limit section as the lower limit value and the upper limit value, respectively. The associated section is the second upper limit section, the section associated with the upper limit product is the second lower limit section, the upper limit value of the second upper limit section and the lower limit value of the second lower limit section are the upper limit value and the lower limit value, respectively. The second search interval to be obtained is obtained (step S102). On the other hand, if the reception unit 102 determines that the request has not been received (step S101; No), it waits as it is.
　例えば、受付部１０２が、ショッパーＹから、下限商品に「商品Ｃ」、上限商品に「商品Ａ」が指定された絞込み要求を受信すると、取得部１０３は、下限商品の「商品Ｃ」の区間「１６０ｃｍ～１８０ｃｍ」と、上限商品の「商品Ａ」の区間「１５０ｃｍ～１７０ｃｍ」とを取得する。そして、取得部１０３は、第１検索区間を「１６０ｃｍ～１７０ｃｍ」と求め、第２検索区間を「１５０ｃｍ～１８０ｃｍ」と求める。 For example, when the reception unit 102 receives a narrowing request from the shopper Y in which “product C” is specified as the lower limit product and “product A” is specified as the upper limit product, the acquisition unit 103 reads the “product C” section of the lower limit product. “160 cm to 180 cm” and the section “150 cm to 170 cm” of the upper limit product “product A” are acquired. Then, the acquisition unit 103 obtains the first search section as “160 cm to 170 cm” and obtains the second search section as “150 cm to 180 cm”.
　検索部１０４は、第１検索区間と重複する区間が対応付けられた商品及び第２検索区間と重複する区間が対応付けられた商品を、記憶部１０１から検索する（ステップＳ１０３）。 The search unit 104 searches the storage unit 101 for a product associated with a section overlapping with the first search section and a product associated with a section overlapping with the second search section (step S103).
　例えば、検索部１０４は、図４の商品区間テーブル１０１ａの区間１０１ａ２を参照して、第１検索区間「１６０ｃｍ～１７０ｃｍ」と重複する区間を有する商品を選択し、第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する区間を有する商品を選択する。 For example, the search unit 104 refers to the section 101a2 of the product section table 101a of FIG. 4, selects a product having a section that overlaps the first search section “160cm to 170cm”, and selects the second search section “150cm to 180cm”. ”Is selected.
　検索部１０４は、第１検索区間又は第２検索区間と重複する区間が対応付けられた商品が、記憶部１０１に登録されているか否か（該当商品があるか否か）を判断する（ステップＳ１０４）。検索部１０４が第１検索区間又は第２検索区間と重複する区間が対応付けられた商品が、記憶部１０１に登録されていると判断すると（ステップＳ１０４；Ｙｅｓ）、提示部１０５は、第１検索区間と重複する区間が対応付けられた商品の数（第１検索区間の商品数）が、第２検索区間と重複する区間が対応付けられた商品の数（第２検索区間の商品数）と比較して、所定の比較基準より少ないか否かを判断する（ステップＳ１０５）。一方、検索部１０４が第１検索区間又は第２検索区間と重複する区間が対応付けられた商品が、記憶部１０１に登録されていないと判断すると（ステップＳ１０４；Ｎｏ）、提示部１０５は、該当商品が無い旨をショッパーに提示する（ステップＳ１０９）。 The search unit 104 determines whether or not a product associated with the first search section or a section that overlaps with the second search section is registered in the storage unit 101 (whether there is a corresponding product) (Step S104). S104). When the search unit 104 determines that the product associated with the first search section or the section that overlaps the second search section is registered in the storage unit 101 (step S104; Yes), the presentation unit 105 The number of products associated with the search section and the overlapping section (the number of products in the first search section) is the number of products associated with the section that overlaps with the second search section (the number of products in the second search section). It is judged whether it is less than a predetermined comparison reference (step S105). On the other hand, when the search unit 104 determines that the product associated with the first search section or the section overlapping the second search section is not registered in the storage unit 101 (step S104; No), the presentation unit 105 The shopper is notified that there is no corresponding product (step S109).
　例えば、検索部１０４は、図４の商品区間テーブル１０１ａの区間１０１ａ２を参照して、第１検索区間「１６０ｃｍ～１７０ｃｍ」又は第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する区間を有する商品があるか否かを判断する。検索部１０４は、第１検索区間又は第２検索区間と重複する区間を有する商品があると判断すると、第１検索区間「１６０ｃｍ～１７０ｃｍ」と重複する区間が対応付けられた商品の数「９０」と、第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する区間が対応付けられた商品の数「１２００」とを求め、第１検索区間の商品数「９０」が、第２検索区間の商品数「１２００」と比較して、１０分の１より小さいか否かを判断する。一方、検索部１０４は、図４の商品区間テーブル１０１ａに第１検索区間「１６０ｃｍ～１７０ｃｍ」又は第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する区間を有する商品が登録されていないと判断すると、提示部１０５は、ショッパーＹに該当商品が無い旨のメッセージを提示する。そして、ステップＳ１０１に戻る。 For example, the search unit 104 refers to the section 101a2 of the product section table 101a in FIG. 4, and has a product having a section that overlaps the first search section “160 cm to 170 cm” or the second search section “150 cm to 180 cm”. Determine whether or not. When the search unit 104 determines that there is a product having a section that overlaps the first search section or the second search section, the number of products “90” associated with the section that overlaps the first search section “160 cm to 170 cm”. ”And the number of products“ 1200 ”associated with the second search section“ 150 cm to 180 cm ”, and the number of products“ 90 ”in the first search section is the number of products in the second search section. Compared with “1200”, it is determined whether or not it is smaller than 1/10. On the other hand, when the search unit 104 determines that a product having a section overlapping with the first search section “160 cm to 170 cm” or the second search section “150 cm to 180 cm” is not registered in the product section table 101a of FIG. The presentation unit 105 presents a message indicating that there is no corresponding product in the shopper Y. Then, the process returns to step S101.
　ステップＳ１０５において、第１検索区間の商品数が、第２検索区間の商品数と比較して、所定の比較基準以上と判断すると（ステップＳ１０５；Ｎｏ）、提示部１０５は、第１検索区間と重複する区間が対応付けられた商品を、ショッパーに提示する（ステップＳ１０６）。一方、第１検索区間の商品数が、第２検索区間の商品数と比較して、所定の比較基準より小さいと判断すると（ステップＳ１０５；Ｙｅｓ）、提示部１０５は、第２検索区間と重複する区間が対応付けられた商品を、ショッパーに提示する（ステップＳ１１０）。 In step S105, when the number of products in the first search section is determined to be equal to or greater than a predetermined comparison criterion compared to the number of products in the second search section (step S105; No), the presentation unit 105 The product associated with the overlapping section is presented to the shopper (step S106). On the other hand, when it is determined that the number of products in the first search section is smaller than a predetermined comparison criterion compared to the number of products in the second search section (step S105; Yes), the presenting unit 105 overlaps with the second search section. The product associated with the section to be displayed is presented to the shopper (step S110).
　例えば、第１検索区間「１６０ｃｍ～１７０ｃｍ」の商品数「９０」は、第２検索区間「１５０ｃｍ～１８０ｃｍ」の商品数「１２００」と比較して、１０分の１より小さいので、提示部１０５は、第２検索区間「１５０ｃｍ～１８０ｃｍ」と重複する区間が対応付けられた商品をショッパーＹに提示する。一方、第１検索区間の商品数が、第２検索区間の商品数と比較して、１０分の１以上の場合、提示部１０５は、第１検索区間と重複する区間が対応付けられた商品をショッパーＹに提示する。 For example, the number of products “90” in the first search section “160 cm to 170 cm” is smaller than one-tenth compared to the number of products “1200” in the second search section “150 cm to 180 cm”. Presents the shopper Y with a product associated with the second search section “150 cm to 180 cm” and an overlapping section. On the other hand, when the number of products in the first search section is one-tenth or more compared to the number of products in the second search section, the presentation unit 105 stores a product associated with a section overlapping with the first search section. To shopper Y.
　ステップＳ１０６の後、更新部１０６は、第１下限区間と第１上限区間とが重複するか否か（重複区間があるか否か）を判断する（ステップＳ１０７）。更新部１０６は、第１下限区間と第１上限区間とが重複すると判断すると（ステップＳ１０７；Ｙｅｓ）、記憶部１０１に記憶された第１下限区間の上限値を減少させた値に更新し、記憶部１０１に記憶された第１上限区間の下限値を増加させた値に更新する（ステップＳ１０８）。一方、更新部１０６は、第１下限区間と第１上限区間とが重複しないと判断すると（ステップＳ１０７；Ｎｏ）、ステップＳ１０１に戻る。 After step S106, the update unit 106 determines whether the first lower limit section and the first upper limit section overlap (whether there is an overlapping section) (step S107). When the update unit 106 determines that the first lower limit interval and the first upper limit interval overlap (step S107; Yes), the update unit 106 updates the upper limit value of the first lower limit interval stored in the storage unit 101 to a value that is decreased. The lower limit value of the first upper limit section stored in the storage unit 101 is updated to a value increased (step S108). On the other hand, when the update unit 106 determines that the first lower limit section and the first upper limit section do not overlap (step S107; No), the update unit 106 returns to step S101.
　また、ステップＳ１１０の後、更新部１０６は、第２下限区間と第２上限区間とが重複するか否かを判断する（ステップＳ１１１）。更新部１０６は、第２下限区間と第２上限区間とが重複すると判断すると（ステップＳ１１１；Ｙｅｓ）、記憶部１０１に記憶された第２下限区間の上限値を減少させた値に更新し、記憶部１０１に記憶された第２上限区間の下限値を増加させた値に更新する（ステップＳ１１２）。一方、更新部１０６は、第２下限区間と第２上限区間とが重複しないと判断すると（ステップＳ１１１；Ｎｏ）、ステップＳ１０１に戻る。 Further, after step S110, the updating unit 106 determines whether or not the second lower limit section and the second upper limit section overlap (step S111). When the update unit 106 determines that the second lower limit interval and the second upper limit interval overlap (step S111; Yes), the update unit 106 updates the value to a value obtained by reducing the upper limit value of the second lower limit interval stored in the storage unit 101, The lower limit value of the second upper limit section stored in the storage unit 101 is updated to the increased value (step S112). On the other hand, when the update unit 106 determines that the second lower limit section and the second upper limit section do not overlap (Step S111; No), the update unit 106 returns to Step S101.
　例えば、「商品Ｃ」が下限商品、「商品Ａ」が上限商品で、第１検索区間「１６０ｃｍ～１７０ｃｍ」の商品数が「９０」、第２検索区間「１５０ｃｍ～１８０ｃｍ」の商品数が「１２００」の場合、ステップＳ１０５から、ステップＳ１１０に進む。そして、第２下限区間「１５０ｃｍ～１７０ｃｍ」と、第２上限区間「１６０ｃｍ～１８０ｃｍ」とは重複区間があるので、更新部１０６は、重複区間が小さくなるように、第２下限区間の上限値「１７０ｃｍ」を「１６８ｃｍ」に変更し、第２上限区間の下限値「１６０ｃｍ」を「１６２ｃｍ」に変更し、それぞれ変更した値を、商品区間テーブル１０１ａに登録する。 For example, “product C” is the lower limit product, “product A” is the upper limit product, the number of products in the first search section “160 cm to 170 cm” is “90”, and the number of products in the second search section “150 cm to 180 cm” is “ In the case of “1200”, the process proceeds from step S105 to step S110. Since the second lower limit section “150 cm to 170 cm” and the second upper limit section “160 cm to 180 cm” have overlapping sections, the updating unit 106 sets the upper limit value of the second lower limit section so that the overlapping sections become smaller. “170 cm” is changed to “168 cm”, the lower limit value “160 cm” of the second upper limit section is changed to “162 cm”, and the changed values are registered in the product section table 101a.
　一方、例えば、「商品Ａ」が下限商品、「商品Ｂ」が上限商品で、第１検索区間「１５０ｃｍ～１７５ｃｍ」の商品数が「１０００」、第２検索区間「１５５ｃｍ～１７０ｃｍ」の商品数が「７００」の場合、ステップＳ１０５から、ステップＳ１０６に進む。そして、第１下限区間「１５０ｃｍ～１７０ｃｍ」と、第１上限区間「１５５ｃｍ～１７５ｃｍ」とは重複区間があるので、更新部１０６は、第１下限区間の上限値「１７０ｃｍ」を「１６８ｃｍ」に変更し、第１上限区間の下限値「１５５ｃｍ」を「１５７ｃｍ」に変更し、それぞれ変更した値を、商品区間テーブル１０１ａに登録する。 On the other hand, for example, “Product A” is the lower limit product, “Product B” is the upper limit product, the number of products in the first search section “150 cm to 175 cm” is “1000”, and the number of products in the second search section “155 cm to 170 cm”. Is "700", the process proceeds from step S105 to step S106. Since the first lower limit section “150 cm to 170 cm” and the first upper limit section “155 cm to 175 cm” have overlapping sections, the updating unit 106 sets the upper limit value “170 cm” of the first lower limit section to “168 cm”. The lower limit value “155 cm” of the first upper limit section is changed to “157 cm”, and the changed values are registered in the product section table 101a.
