FIG. 3 is a flowchart showing an example of the processing of the overall history acquisition unit 51 , the related
首先,全體履歷取得部51,係將關於複數個使用者的購入履歷及瀏覽履歷,加以取得(步驟S101)。全體履歷取得部51,係可針對某個店舖,無論使用者為何,而將記憶部12中所被儲存之購入履歷及瀏覽履歷加以取得,亦可針對資訊處理系統所管理的所有店舖,而將記憶部12中所被儲存之購入履歷及瀏覽履歷加以取得。又所被取得的購入履歷及瀏覽履歷亦可為過去1年中的購入履歷及瀏覽履歷。First, the overall history acquisition unit 51 acquires purchase histories and browsing histories of a plurality of users (step S101). The overall history acquisition unit 51 can acquire the purchase history and browsing history stored in the
接著,關連類型決定部52,係從已被取得之購入履歷,抽出由曾被一起購入之品項所成之組合,從已被取得之瀏覽履歷,抽出由曾被一起瀏覽過之品項所成之組合(步驟S102)。然後,關連類型決定部52,係將已被抽出之組合中所包含之品項之各者所屬之類型,加以取得(步驟S103)。嚴謹來說,類型係可具有階層結構,關連類型決定部52係可取得最下層之類型(在類型為3階層的情況下則為第3階層之類型)。此處所被使用的類型,係可為某個店舖中的類型,也可為在全部店舖間為共通的類型。Next, the correlation
然後,關連類型決定部52,係基於組合中所包含之品項之各者所屬之類型,而決定互相關連的類型之集合(步驟S104)。關連類型決定部52,係將組合中所包含之品項的所屬之類型的集合加以統計,基於該所被統計出來的類型之集合之數量,而決定互相關連的類型之集合。例如,關連類型決定部52,係在所被統計出來的類型之集合之數量是大於閾值的情況下,則可將該類型之集合決定成為互相關連的類型之集合。Then, the related
又,關連品項決定部53,係基於已被抽出之組合中所包含之品項,而決定互相關連的品項之集合(步驟S105)。例如,關連品項決定部53,係可將組合的出現次數予以計數,基於該已被計數之次數而決定互相關連的品項之集合。例如,關連品項決定部53,係在已被計數之組合的出現次數是大於閾值的情況下,則可將該組合中所包含之品項決定成為互相關連的品項之集合。Furthermore, the related
此外,關連類型決定部52,係亦可針對已被關連品項決定部53所決定之互相關連的品項之集合,將由該集合中所包含之品項之各者所屬之類型所成之集合,決定成為互相關連的類型之集合。In addition, the related
又,再購入可能性取得部54係針對每一品項而算出再購入可能性(步驟S106)。例如,再購入可能性係亦可為,在購入了算出對象之品項的使用者之中,將該品項購入了複數次的使用者之比率,視為再購入率。此外,再購入可能性取得部54,係亦可將已被算出之再購入可能性是大於所定之條件也就是閾值的品項,當作再購入可能性高的品項而儲存在記憶部12中。Furthermore, the repurchase possibility acquisition unit 54 calculates the repurchase possibility for each item (step S106). For example, the repurchase possibility may be the ratio of users who purchased the item to be calculated multiple times among users who purchased the item to be calculated, which may be regarded as the repurchase rate. In addition, the repurchase possibility acquisition unit 54 may store items whose repurchase possibility is greater than a predetermined condition, that is, a threshold, in the
又,再購入可能性,係亦可使用學習模型來做預測。再購入可能性取得部54,係基於使用者所致之品項的過去之購入日,而將再購入可能性加以取得。具體而言,再購入可能性取得部54係使用,把品項的過去之購入日當作輸入,然後會輸出品項之再購入可能性的學習模型,來取得品項之再購入可能性。學習模型,係利用神經網路等公知之機器學習演算法,並藉由把使用者所購入之品項的過去之購入日、與使用者所致之再購入之有無之關係當作教師資料而進行學習的監督式機器學習,而被生成。再購入可能性取得部54,係亦可在使用者之購入履歷中所包含之品項之中,將再購入可能性是滿足所定之條件的品項,當作再購入可能性高的品項而儲存在記憶部12中。例如,學習模型是將再購入可能性以數值的方式進行輸出的情況下,則亦可將再購入可能性是大於所定之條件也就是閾值的品項,當作再購入可能性高的品項。又,學習模型是輸出有或無來作為再購入可能性的情況下,則亦可將再購入可能性是達到所定之條件(例如有)的品項,當作再購入可能性高的品項。In addition, the repurchase possibility can also be predicted using a learning model. The repurchase possibility acquisition unit 54 acquires the repurchase possibility based on the past purchase date of the item by the user. Specifically, the repurchase possibility acquisition unit 54 uses a learning model that takes the past purchase date of the item as input and then outputs the repurchase possibility of the item to obtain the repurchase possibility of the item. The learning model utilizes well-known machine learning algorithms such as neural networks, and uses the relationship between the past purchase date of the item purchased by the user and the presence or absence of repurchase by the user as teacher data. Supervised machine learning to learn and be generated. The repurchase possibility acquisition unit 54 may also regard the items whose repurchase possibility satisfies the predetermined conditions among the items included in the user's purchase history as the items with high repurchase possibility. and stored in the
品項的過去之購入日與再購入可能性,係存在有一定的關係。例如,使用者最近購入的品項、或使用者很久以前購入過的品項,係由於在現時點上的使用者的購入慾望較低,因此再購入可能性是呈現較低的傾向。另一方面,使用者會定期性購入的品項,則在下個購入時期中,品項之再購入可能性是呈現較高的傾向。藉由使用將品項的過去之購入日與再購入之有無進行過學習的學習模型,就可高精度地判定使用者的再購入可能性。There is a certain relationship between the item's past purchase date and the repurchase possibility. For example, items that the user purchased recently or items that the user purchased long ago have a low repurchase possibility because the user's purchase desire at the current point is low. On the other hand, for items that users purchase regularly, the probability of repurchase of the items in the next purchase period is higher. By using a learning model that learns the past purchase date of the item and whether it has been repurchased, the user's repurchase possibility can be determined with high accuracy.
此外,學習模型的輸入資料,係不限於品項的過去之購入日。例如,輸入資料係亦可為再購入率。藉此就可進行,反映出每一品項之再購入實際結果的預測。例如,輸入資料係亦可為,使用者所致之過去的品項之購入次數。藉此就可進行,反映出每一使用者的品項之購入實際結果的預測。例如,輸入資料係亦可為,使用者所致之前次的品項之購入數。藉此就可進行,反映出隨著前次的品項之購入數而變化的,前次購入時期與下次購入時期之期間的預測。例如,輸入資料係亦可為品項之價格。藉此就可進行,高價格之品項係會再購入可能性變低的此種反映出品項之價格的預測。例如,輸入資料係亦可為品項所屬之類型的再購入率。藉此,即使針對購入實際結果較少的品項,仍可進行與品項之再購入率存有相關關係的反映出類型之再購入率的預測。此外,亦可將上記輸入資料之中的複數個輸入資料,當作學習模型的輸入資料。藉由使用將上記輸入資料、與使用者所致之再購入之有無之關係當作教師資料而進行過學習的學習模型,就可高精度地判定使用者的再購入可能性。In addition, the input data of the learning model is not limited to the past purchase date of the item. For example, the input data may also be the repurchase rate. This enables predictions that reflect the actual repurchase results for each item. For example, the input data may also be the number of purchases of items in the past caused by the user. In this way, predictions can be made that reflect the actual purchase results of each user's items. For example, the input data may also be the number of items purchased last time by the user. This makes it possible to predict the period between the previous purchase period and the next purchase period, reflecting changes in the number of items purchased last time. For example, the input data can also be the price of the item. This makes it possible to predict the price of items that reflect the low likelihood of repurchasing high-priced items. For example, the input data may also be the repurchase rate of the type to which the item belongs. This makes it possible to predict the repurchase rate of the type that is correlated with the repurchase rate of the item, even for an item whose actual purchase results are small. In addition, multiple input data among the above-mentioned input data can also be used as input data for the learning model. By using a learning model that has learned the relationship between the above input data and the user's repurchase as teacher data, the user's repurchase possibility can be determined with high accuracy.

針對步驟S205之處理進行具體的說明。圖7係為類型利用部61的處理之一例的圖示。首先,類型利用部61中所包含的類型選擇部66,係將由購入履歷或瀏覽履歷所成之行動履歷中所包含之各個品項的類型,加以取得(步驟S301)。例如於步驟S205中,行動履歷係為購入履歷。然後,類型選擇部66,係基於已被關連類型決定部52所決定之互相關連的複數個類型之集合,而將與已被取得之類型相關連之類型(關連類型),加以選擇(步驟S302)。The processing of step S205 will be described in detail. FIG. 7 is a diagram illustrating an example of processing by the
品項選擇部67,係在隸屬於關連類型且為該店舖所陳列的品項之中,將順位最高的品項,當作候補品項而加以選擇(步驟S303)。順位,係可基於其在該類型中的販售數量或販售額,而被設定。又,品項選擇部67,係從已被選擇之品項中,刪除與從其他行動履歷所被選擇出來之品項重複的品項(步驟S304)。然後,品項選擇部67係在已被選擇之品項之中,將尚有庫存之品項當作候補品項而加以選擇(步驟S305),清單追加部58係將候補品項追加至清單。The item selection unit 67 selects the highest-ranked item as a candidate item among the items belonging to the related type and displayed in the store (step S303). The order can be set based on its sales quantity or sales amount in that type. Furthermore, the item selection unit 67 deletes items that overlap with items selected from other action histories from the selected items (step S304). Then, the item selecting unit 67 selects items that are still in stock among the selected items as candidate items (step S305), and the
針對步驟S206之處理也做說明。圖8係為品項利用部62的處理之一例的圖示。首先,品項利用部62中所包含的品項選擇部69,係基於已被關連品項決定部53所決定之互相關連的複數個品項之集合,而將與行動履歷中所包含之各個品項相關連,且為該店舖中所陳列的品項,加以選擇(步驟S401)。品項選擇部69,係從已被選擇之品項中刪除重複的品項(步驟S402),將已被選擇之品項之中尚有庫存之品項,當作候補品項而加以選擇(步驟S403)。清單追加部58係將候補品項追加至清單。The processing of step S206 will also be described. FIG. 8 is a diagram illustrating an example of processing by the
此處,於步驟S202中未取得購入履歷的情況下(步驟S203的N),則往步驟S207遷移。Here, if the purchase history is not acquired in step S202 (N in step S203), the process proceeds to step S207.
在瀏覽履歷已被取得的情況下(步驟S207的Y),則關連候補取得部57中所包含的類型利用部61,係基於瀏覽履歷與關連類型而將品項當作候補品項而加以選擇,清單追加部58係將已被選擇之候補品項追加至清單(步驟S208)。步驟S208的細節,係於圖7所示的處理中將行動履歷改成瀏覽履歷。關連候補取得部57中所包含的品項利用部62,係基於瀏覽履歷與關連品項而將品項當作候補品項而加以選擇,清單追加部58係將已被選擇之候補品項追加至清單(步驟S209)。步驟S209的處理之細節,係於圖8所示的處理中將行動履歷改成瀏覽履歷。一旦步驟S208、S209之處理被進行,則處理係往步驟S219遷移。When the browsing history has been acquired (Y in step S207), the
此處,於步驟S202中未取得瀏覽履歷的情況下(步驟S207的N),則往步驟S210遷移。Here, if the browsing history is not obtained in step S202 (N in step S207), the process proceeds to step S210.
步驟S210至步驟S217所記載之處理,係為使用者在其所存取之店舖中沒有購入履歷及瀏覽履歷存在之情況下的處理。The processes described in steps S210 to S217 are processes performed when the user does not have a purchase history or a browsing history in the store accessed by the user.
在步驟S210中,使用者履歷取得部55,係將使用者在其他店舖中的購入履歷及瀏覽履歷,加以取得(步驟S210)。此處,在購入履歷、瀏覽履歷均無法被取得的情況下(步驟S211的N),則由於無法基於購入履歷、瀏覽履歷進行推薦,因此清單追加部58係將使用者所存取的店舖之銷售排行榜中所包含之品項,追加至清單(步驟S212)。In step S210, the user
另一方面,在購入履歷已被取得的情況下(步驟S211的Y且步驟S213的Y),關連候補取得部57中所包含的類型利用部61,係基於其他店舖中的購入履歷與關連類型,從該店舖所陳列的品項中選擇出候補品項,將已被選擇之候補品項追加至清單(步驟S215)。步驟S215之處理,係於圖7所示的處理中將行動履歷改成其他店舖中的購入履歷。在購入履歷未被取得的情況下(步驟S211的Y且步驟S213的N),則步驟S215係被略過。On the other hand, when the purchase history has been acquired (Y in step S211 and Y in step S213), the
又,在瀏覽履歷已被取得的情況下(步驟S211的Y且步驟S216的Y),關連候補取得部57中所包含的類型利用部61,係基於其他店舖中的瀏覽履歷與關連類型,從該店舖所陳列的品項中選擇出候補品項,將已被選擇之候補品項追加至清單(步驟S217)。步驟S217之處理,係於圖7所示的處理中將行動履歷改成其他店舖中的瀏覽履歷。在瀏覽履歷未被取得的情況下(步驟S211的Y且步驟S216的N),則步驟S217係被略過,而遷移至步驟S219。In addition, when the browsing history has been acquired (Y in step S211 and Y in step S216), the
此處,針對藉由步驟S202至S217而被追加至清單之品項,說明具體的例子。Here, a specific example will be described regarding the items added to the list in steps S202 to S217.
圖9係為店舖S中的購入履歷與被追加至清單之品項的關係之一例的圖示。店舖S,假設係為使用者所存取的店舖。在圖9所示的案例中,於店舖S中該使用者之購入履歷係為存在,購入履歷中所包含之品項,係為廚房紙巾A、衛生紙B、紙尿布C、礦泉水D。清單係含有:藉由再購入候補取得部56(對應於第1選擇手法)而被取得之品項也就是廚房紙巾A、衛生紙B、紙尿布C(參照圖9的「再購入之提案」)、和藉由關連候補取得部57(對應於第2選擇手法)中所包含的類型利用部61而被選擇之品項也就是奶粉E、嬰兒食品F、熱水瓶G(參照圖9的「關連類型所致之提案」)、和藉由關連候補取得部57(對應於第2選擇手法)中所包含的品項利用部62而被選擇之品項也就是礦泉水H、礦泉水J12瓶集合包(參照「關連品項所致之提案」)。又於圖9中假設位於上方的品項係順位較高。FIG. 9 is a diagram illustrating an example of the relationship between the purchase history in store S and items added to the list. Store S is assumed to be a store accessed by the user. In the case shown in Figure 9, the user's purchase history exists in store S, and the items included in the purchase history are kitchen towel A, toilet paper B, diaper C, and mineral water D. The list includes items acquired through the repurchase candidate acquisition unit 56 (corresponding to the first selection method), namely, kitchen towel A, toilet paper B, and disposable diaper C (refer to "Repurchase Proposal" in Fig. 9) , and the items selected by the
已被追加至清單中的廚房紙巾A、衛生紙B、紙尿布C係為,使用者於店舖S中的購入履歷中所包含之品項之中,再購入可能性較高者。再購入可能性較低的礦泉水D則未被追加至清單。Kitchen paper towel A, toilet paper B, and disposable diaper C that have been added to the list are items included in the user's purchase history in store S that are more likely to be repurchased. Mineral water D, which is less likely to be repurchased, was not added to the list.
紙尿布C係隸屬於「紙尿布」之類型,奶粉E、嬰兒食品F、熱水瓶G係分別隸屬於「奶粉」、「嬰兒食品」、「嬰兒用品」之類型。「紙尿布」之類型,與「奶粉」、「嬰兒食品」、「嬰兒用品」之類型係為互相關連,關連候補取得部57的類型利用部61,係於「紙尿布」相關連之類型之各者中將順位最高的品項也就是奶粉E、嬰兒食品F、熱水瓶G,當作要進行提案的候補而加以選擇。此處,類型利用部61係在關於順位最高的品項而沒有庫存的情況下,則不將品項當作候補而加以選擇。此情況下,類型利用部61係亦可將尚有庫存之品項之中順位最高的品項,當作候補而加以選擇。又,關連候補取得部57的品項利用部62,係亦可將與礦泉水D相關連之礦泉水H、礦泉水J12瓶集合包,當作要進行提案的候補而加以選擇。此處,品項利用部62係不將沒有庫存的品項當作候補而加以選擇。Diaper C belongs to the type of "disposable diapers", milk powder E, baby food F, and thermos bottle G belong to the types of "milk powder", "baby food" and "baby products" respectively. The type of "disposable diaper" is related to the types of "milk powder", "baby food", and "baby supplies", and the
藉由不只是基於相關連之品項而還基於相關連之類型來選擇要進行提案之品項,被提案給使用者的品項的幅度就會變大,且所被提案之品項更貼切於使用者之狀況的可能性會變高。藉此,可一面提高品項被購入之可能性,一面減輕使用者檢索品項的麻煩,可提升易用性。又,被輸入了使用者所曾經購入或瀏覽過之品項的資訊處理伺服器,係藉由參照含有互相關連之複數個類型的集合,而自動地輸出要進行提案之品項。藉此,可高速且高精度地取得要對使用者進行提案之品項。又,相較於品項的數量,類型的數量較少,因此可降低資訊處理伺服器所處理的資料量,可降低處理負荷。By selecting items to propose based not just on related items but also on related types, the range of items proposed to the user becomes larger and the items proposed are more relevant. The possibility will become higher depending on the user's condition. In this way, the possibility of the item being purchased can be increased, while the user's trouble of retrieving the item can be reduced, and the ease of use can be improved. In addition, the information processing server that has been input with items that the user has purchased or browsed automatically outputs items to be proposed by referring to a collection of multiple types that are related to each other. This makes it possible to obtain items to be proposed to the user at high speed and with high accuracy. In addition, compared with the number of items, the number of types is small, so the amount of data processed by the information processing server can be reduced, and the processing load can be reduced.
圖10係為店舖S中的購入履歷及瀏覽覽歷與被追加至清單之品項的關係之一例的圖示。在圖10所示的案例中,於店舖S中係不存在有該使用者之購入履歷,但存在有瀏覽履歷。瀏覽履歷中所包含之品項,係為咖啡K、卸妝乳L。卸妝乳L所屬之類型「卸妝乳」,與防曬油O所屬之類型「防曬油」係為互相關連,因此會像這樣選擇會成為候補的品項。於此案例中也是,藉由類型利用部61的互相關連之類型所致之提案的品項之選擇,與品項利用部62的互相關連之品項所致之提案的品項之選擇,這2個手法(亦可使其對應於第1選擇手法及第2選擇手法)所致之候補的選擇係被進行。此外,即使在店舖S中存在有使用者之購入履歷的情況下,仍可基於瀏覽履歷來進行候補之選擇。FIG. 10 is a diagram illustrating an example of the relationship between the purchase history and browsing history in store S and items added to the list. In the case shown in Figure 10, there is no purchase history of the user in store S, but there is a browsing history. The items included in the browsing history are coffee K and makeup remover L. The type "makeup remover" to which makeup remover L belongs is related to the type "sunscreen oil" to which sunscreen oil O belongs, so the items that will become candidates are selected like this. In this case as well, the selection of proposed items based on the mutually related types of the
圖11係為購入履歷及瀏覽履歷與被追加至清單之品項的關係之一例的圖示。在圖11所示的案例中,於店舖S中係該使用者之購入履歷與瀏覽履歷皆不存在,但卻存在有於其他店舖中的購入履歷及瀏覽履歷。於其他店舖中的購入履歷係含有紙尿布C,瀏覽履歷係含有卸妝乳L。於此案例中,關連候補取得部57的類型利用部61,係藉由基於購入履歷的候補之選擇,與基於瀏覽履歷的候補之選擇這2個選擇手法,來進行候補之選擇。此外,即使在店舖S中存在有使用者之購入履歷或瀏覽履歷的情況下,仍可基於其他店舖中的購入履歷或瀏覽履歷來進行候補之選擇。FIG. 11 is a diagram illustrating an example of the relationship between purchase history and browsing history and items added to the list. In the case shown in Figure 11, the user's purchase history and browsing history do not exist in store S, but there are purchase histories and browsing histories in other stores. The purchase history from other stores contains diaper C, and the browsing history contains makeup remover L. In this case, the
此外,資訊處理伺服器1,係可基於其他店舖中的購入履歷或瀏覽履歷,藉由各種的選擇手法,來選擇店舖S中的候補品項。例如,在店舖S有陳列其他店舖中的使用者之購入履歷或瀏覽履歷中所包含之品項的情況下,則亦可將與其他店舖中的使用者之購入履歷或瀏覽履歷中所包含之品項相同的品項,當作店舖S中的候補品項而加以選擇。此時,在其他店舖中的使用者之購入履歷中所包含之品項之中,亦可將再購入可能性高的品項,當作店舖S中的候補品項而加以選擇。例如,關連候補取得部57中所包含的類型利用部61,係亦可基於其他店舖中的使用者之購入履歷或瀏覽履歷,藉由互相關連的類型,而將店舖S中的候補品項加以選擇。例如,關連候補取得部57中所包含的品項利用部62,係亦可基於其他店舖中的使用者之購入履歷或瀏覽履歷,藉由互相關連的品項,而將店舖S中的候補品項加以選擇。In addition, the
於使用者正在存取之店舖中,基於其他店舖中的使用者之購入履歷或瀏覽履歷來選擇候補品項,藉此,就可考慮到其他店舖中的使用者之購入履歷或瀏覽履歷而將適切的品項進行提案。藉此,可一面提高品項被購入之可能性,一面減輕使用者檢索品項的麻煩,可提升易用性。In the store that the user is accessing, candidate items are selected based on the purchase history or browsing history of users in other stores. This way, the purchase history or browsing history of users in other stores can be considered. Propose appropriate items. In this way, the possibility of the item being purchased can be increased, while the user's trouble of retrieving the item can be reduced, and the ease of use can be improved.
在步驟S219中,輸出部59,係將含有清單的提案畫面,輸出至客戶端裝置2所擁有的,或被連接在客戶端裝置2上的顯示裝置。此處,輸出部59,係以使得清單中所包含之候補品項是被配置在相應於其順序之位置上的方式,而將提案畫面予以輸出。例如,提案畫面,係於使用者所存取的店舖之網頁中所被顯示的畫面。In step S219, the
圖12係為被輸出的提案畫面之一例的圖示。提案畫面中係被配置有複數追加鈕81、和結帳鈕84,且配置有清單中所包含之複數個品項。品項之各者,係伴隨著個別追加鈕82、勾選盒83而被配置。FIG. 12 is an illustration of an example of an output proposal screen. A plurality of add buttons 81 and a checkout button 84 are arranged in the proposal screen, and a plurality of items included in the list are arranged. Each item is configured with its own add button 82 and check box 83 .
個別追加鈕82係為,用來讓使用者指示把對應之品項追加至購物車所需之按鈕。勾選盒83係為用來勾選對應之品項所需之按鈕,複數追加鈕81係為,在被按下之際用來指示將已被勾選之勾選盒83所對應之品項追加至購物車所需之按鈕。結帳鈕84係為,針對已被追加至購物車之品項而用來指示購入處理之開始所需之按鈕。客戶端裝置2,係一旦個別追加鈕82、結帳鈕84之任一者被按下,就將表示該事實的資訊,發送至資訊處理伺服器1。客戶端裝置2,係一旦複數追加鈕81被按下,則將表示被按下之際已被勾選的勾選盒83所對應之品項的資訊,以及表示已被按下之事實的資訊,一起發送至資訊處理伺服器1。The individual add button 82 is a button used to allow the user to instruct the user to add the corresponding item to the shopping cart. The check box 83 is a button required to check the corresponding item, and the plural add button 81 is used to instruct the item corresponding to the check box 83 to be checked when pressed. Add to cart button required. The checkout button 84 is a button necessary to instruct the start of the purchase process for the item that has been added to the shopping cart. Once either the individual add button 82 or the checkout button 84 is pressed, the
在提案畫面中,例如像是再購入候補與基於關連之類型的候補這樣,藉由複數個手法所被選擇且被追加至相同清單中的候補品項,係被整合在一起而被顯示。藉此,使用者所參照的場所就會集中一處,可降低參照商品的負荷。又,資訊處理伺服器,係將藉由複數個手法所選擇的候補品項,不是以不同的清單之資料,而是以同一清單之資料的方式,發送至客戶端裝置。藉此,可降低資訊處理伺服器發送給客戶端裝置的資料量,因此可降低通訊負荷,同時可使客戶端裝置中的提案畫面之顯示處理高速化。On the proposal screen, candidate items selected by a plurality of methods and added to the same list, such as repurchase candidates and candidates based on relationship types, are integrated and displayed. In this way, the places that users refer to can be concentrated in one place, which can reduce the load of reference products. In addition, the information processing server sends the candidate items selected through multiple methods to the client device not as data in different lists but as data in the same list. This can reduce the amount of data sent by the information processing server to the client device, thereby reducing the communication load and speeding up the display processing of the proposal screen in the client device.
步驟S221至S229,係為使用者對提案畫面進行了操作之際的處理。以下針對該處理進行說明。Steps S221 to S229 are processes performed when the user operates the proposal screen. This processing is explained below.
在步驟S221中,購物車控制部60係判定是否藉由使用者而按下了個別追加鈕82。在個別追加鈕82已被按下的情況下(步驟S221的Y),則購物車控制部60係將已被按下之個別追加鈕82所對應之品項,追加至購物車(步驟S222)。然後,遷移至步驟S225,輸出部59係將已被追加至購物車之品項的個別追加鈕82,變更成數量輸入欄85(參照圖13)。往數量輸入欄85之變更,係可藉由客戶端裝置2來執行連同提案畫面之資料一併被發送的程式,而將正在被顯示的個別追加鈕82置換成數量輸入欄85來加以實現,亦可藉由資訊處理伺服器1將已經把個別追加鈕82置換成數量輸入欄85的提案畫面之資料發送至客戶端裝置2,客戶端裝置2就將該提案畫面加以顯示而加以實現。In step S221, the shopping
圖13係為購物車中被追加了品項後的提案畫面之一例的圖示。在圖13的例子中係圖示,於圖12中所被提案之品項之中關於位於左上之品項而在個別追加鈕82已被按下的情況下,該個別追加鈕82係變化成數量輸入欄85的樣子。FIG. 13 is an illustration of an example of a proposal screen after items are added to the shopping cart. In the example of FIG. 13 , when the individual add button 82 is pressed for the upper left item among the proposed items in FIG. 12 , the individual add button 82 changes to The quantity input field looks like 85.
在個別追加鈕82未被按下的情況下(步驟S221的N),則購物車控制部60係判定複數追加鈕81是否已被按下(步驟S223)。在複數追加鈕81已被按下的情況下(步驟S223的Y),則購物車控制部60係將對應之勾選盒83已被勾選之品項,追加至購物車(步驟S224)。然後,於步驟S225中,輸出部59係將已被追加至購物車之品項的個別追加鈕82,變更成數量輸入欄85。When the individual add button 82 has not been pressed (N in step S221), the shopping
一旦步驟S225之處理被進行,則步驟S221以後之處理會被重複。Once the processing of step S225 is performed, the processing after step S221 will be repeated.
另一方面,在複數追加鈕81未被按下的情況下(步驟S223的N),則購物車控制部60係判定數量輸入欄85是否已被變更(步驟S226)。在數量輸入欄85已被變更的情況下(步驟S226的Y),購物車控制部60係將已被變更之數量輸入欄85所對應之品項的購物車內之數量,予以變更(步驟S227)。其後,重複步驟S221以後之處理。On the other hand, when the plural add button 81 is not pressed (N in step S223), the shopping
在數量輸入欄85未被變更的情況下(步驟S226的N),則購物車控制部60係判定結帳鈕84是否已被按下(步驟S228)。在結帳鈕84已被按下的情況下(步驟S228的Y),則購物車控制部60係進行,購物車中所存在之品項之購入的相關處理,更具體而言係執行結帳及配送之相關處理(步驟S229)。另一方面,在結帳鈕84未被按下的情況下(步驟S228的N),則重複步驟S221以後之處理。If the quantity input field 85 has not been changed (N in step S226), the shopping
