[1. Exhibit transaction processing]
The exhibit transaction processing according to the embodiment will be described with reference to FIG. FIG. 1 is an explanatory diagram of an auction item transaction process according to the embodiment. In the present embodiment, an auction item transaction process is executed by an auction item transaction processing device 1 that provides an auction item transaction service.

In the example shown in FIG. 1, the user U ₁ transmits the exhibition request goods D was exhibit a seller from the terminal device 2 ₁ to exhibit transaction apparatus 1 (step S1). The listing request includes information such as a description of the product D, an image of the product D, a start price, and a lowest price. The start price is the transaction price P of the product D at the start of the listing, and the lowest price is the lowest price of the transaction price P of the product D.

Exhibits transaction processing apparatus 1 accepts the exhibition request from the terminal device 2 _1, based on the commodity information contained in such exhibition request, it starts the exhibition process. After such exhibition processing is performed, if there is a list request from the terminal device 2 ₂ users U ₂ utilizing exhibit transaction processing apparatus 1 (step S2), and exhibits the transaction processing apparatus 1, an exhibit list screen The information of 61 is transmitted (step S3). Based on the information of such exhibit list screen 61, exhibit list screen 61 is displayed on the display unit 12 of the terminal device 2 _2.

The exhibit transaction processing apparatus 1 generates the exhibit list screen 61 so that the exhibit start date and time are newer and are presented to the higher priority. Therefore, as in the exhibit list screen 61 displayed on the display unit 12 of the terminal device 2 _2, the presentation position of the product D (an example of a presentation order) is a position L1 which is the highest, in such a position L1 Information on the product D is displayed. Selecting the position L1 exhibits list screen 61 (e.g., click) by, exhibit screen corresponding to the exhibition information item D is displayed on the display unit 12 of the terminal device 2 _2.

In the example shown in FIG. 1, by the display unit 12 of the terminal device 2 ₂ and displays information exhibits a position L1 to L15, the user U _2, the scrolling operation of the exhibit list screen 61, It is possible to confirm the exhibited item after the position L16.

Thereafter, when there is a list request from the terminal device 2 ₃ users U ₃ utilizing exhibit transaction processing apparatus 1 (step S4), and exhibits the transaction processing apparatus 1 transmits the information of the exhibit list screen 61 ( Step S5). Based on the information of such exhibit list screen 61, exhibit list screen 61 is displayed on the display unit 12 of the terminal device 2 _3.

As described above, items with a newer exhibition start date and time are displayed with higher priority, so that the presentation position of the information of the product D becomes a lower position with the lapse of time. In the example shown in FIG. 1, as in the exhibit list screen 61 displayed on the display unit 12 of the terminal device 2 _3, the presentation position of the item D is the position L33 which lowered repeatedly from the position L1, in such a position L33 Information on the product D is displayed.

After setting the transaction price P of the product D to the start price, the exhibit transaction processing device 1 performs a process of gradually decreasing the transaction price P when the product D is not purchased yet (step S6). In this way, the auction item transaction processing apparatus 1 performs a process of gradually lowering the transaction price P when the state that the auction item is not purchased continues.

Therefore, for example, the setting of the transaction price P by the seller is different from the price at which the user who considers the purchase of the exhibit (hereinafter referred to as a purchase reviewer) tries to purchase the exhibit. Even in this case, it is possible to reduce the possibility that the exhibit is not purchased. On the other hand, as described above, since the presentation position of the information of the product D becomes a lower position with the lapse of time, even if the transaction price P of the product D is gradually reduced, the existence of the product D is grasped. The likelihood of being reduced is decreasing.

Therefore, the exhibit transaction processing apparatus 1 performs a process of acquiring information on the degree of attention Da for the product D (step S7). The attention level Da for the product D is determined based on, for example, the number of comments for the product D, the number of favorite registrations for the product D, and the number of browses on the auction screen (exhibition page) of the product D.

Then, the auction item transaction processing apparatus 1 determines the presentation position of the auction item (step S8). The exhibit transaction processing apparatus 1 determines the presentation position of the exhibit in the ascending order of the exhibition start date and time (hereinafter, may be referred to as the new arrival order), and also in the descending order of the attention degree Da (hereinafter, the attention order. The presentation position of the exhibit can be determined.

Exhibits transaction processing apparatus 1, when the user U ₄ of the terminal apparatus 2 ₄ utilizing exhibit transaction processing apparatus 1 is focused order list request (step S9), and exhibits transaction processing apparatus 1 determines the target sequence Information on the exhibit list screen 61 arranged at the presented position of the exhibited item is distributed (step S10).

Based on the information of such exhibit list screen 61, exhibit list screen 61 is displayed on the display unit 12 of the terminal device 2 _4. In the example shown in FIG. 1, as in the exhibit list screen 61 displayed on the display unit 12 of the terminal device 2 _4, the presentation position of the item D is a position L8 having up repeatedly from the position L33 to the upper, it takes the position Information on the product D is displayed on L8.

When the attention degree Da of the product D is high, the product D may be purchased, but the presentation position moves to the lower position in the list display in the order of new arrivals, so it may not be purchased even if the transaction price P of the product D is lowered. There is a nature.

On the other hand, in the attention-ordered list display, when the degree of attention of the product D is high, the presentation position of the product D can be moved higher than the presentation position of the new arrival order. Therefore, it is possible to improve the possibility of purchasing the product D while suppressing an excessive decrease in the transaction price P of the product D.

Further, the exhibited item transaction processing device 1 can determine the presented position of the exhibited item in the order in which the presented position in the attention order is adjusted according to the reduction amount ΔP of the transaction price P (hereinafter referred to as the attention adjustment order). it can. For example, the auction item transaction processing apparatus 1 can determine the auction item presentation position by moving up the presentation position in the order of attention in accordance with the size of the decrease ΔP of the transaction price P.

As a result, the larger the reduction amount ΔP of the transaction price P in addition to the attention degree Da, the higher the position of presenting the product D can be moved to the higher position. Therefore, when the reduction amount ΔP of the transaction price P is large, the exhibit item is displayed. Can be more likely to be purchased.

Further, the auction item transaction processing apparatus 1 can determine the presentation position of the auction item in the order in which the presentation positions in the new arrival order are adjusted according to the attention level Da (hereinafter referred to as the new arrival adjustment order). For example, the exhibited item transaction processing device 1 can determine the presented position of the exhibited item by advancing the presented position in the ascending order of the exhibition start date and time according to the magnitude of the attention level Da.

As a result, the presentation position of the product D can be advanced to a higher position if the attention level Da with respect to the product D is high, even if the presentation position of the product start date and time is based on the presentation position in ascending order. Note that the exhibit transaction processing apparatus 1 raises the presentation position of the product D to a higher position as the degree of decrease Da of the transaction price P of the product D is higher, in addition to the attention level Da, based on the presentation position in order of newness. You can also

Further, in the above-described embodiment, the exhibited item transaction processing device 1 has been described with the presentation order of exhibited items as the exhibited position of exhibited items, but the present invention is not limited to this example. For example, when the exhibit transaction processing device 1 dynamically switches the screen for each exhibit according to the exhibit information, the presentation order of the exhibit is the order in which the exhibit appears on the screen.

The terminal device 2 can also generate the exhibit list screen 61 based on the presentation order of the exhibit determined by the exhibit transaction processing device 1. In this case, the auction item transaction processing apparatus 1 transmits, as the information on the auction item list screen 61, information including information on the presentation order of the auction item to the terminal device 2. The terminal device 2 arranges the information of the exhibited items based on the information of the presentation order of the exhibited items, and generates and displays the exhibited item list screen 61.

The above-mentioned exhibition transaction processing may be any exhibition transaction processing in which the purchase is performed at the transaction price P, and is not limited to the exhibition transaction processing in which the transaction price P is gradually reduced. That is, the auction item transaction processing apparatus 1 may be able to determine the presentation order of the auction item in the auction item transaction process in which the item is to be purchased at the transaction price P, based on the degree of attention to the auction item. As a result, it is possible to improve the possibility that the exhibit is purchased.

[2.3.3. Registration processing unit 43]
The registration processing unit 43 (see FIG. 4) receives the registration request transmitted from the terminal device 2, and updates the “registration history” of the exhibition information table corresponding to the exhibition ID included in the registration request. For example, in the state where the exhibition information table is shown in FIG. 6, when there is a registration request for the exhibition item with the exhibition ID “C1”, the registration processing unit 43 displays the user ID and the registration request included in the registration request in the exhibition information table. The date and time are updated, and the number of registration requests (registration number Ne) is updated.

In addition, when the registration processing unit 43 receives the registration request transmitted from the terminal device 2, the registration processing unit 43 associates the user ID with the exhibition ID and stores them in the user information storage unit 31 as a registration result. The user U of the terminal device 2 can operate the terminal device 2 to send a registration list request including the user ID to the exhibit transaction processing device 1.

Upon receiving the registration list request transmitted from the terminal device 2, the registration processing unit 43, based on the user ID included in the registration list request, registers the exhibition ID associated with the user ID in the user information storage unit 31. To get from.

Then, the registration processing unit 43 acquires the exhibition information corresponding to the exhibition ID included in the registration result from the exhibition information storage unit 32, and transmits the information of the registered exhibit list including the acquired exhibition information to the terminal device 2. Thereby, the user U of the terminal device 2 can easily know the information of the registered auction item, and can use the registration button 65 for favorite registration, for example. The registered exhibit list is also called a watch list.

The registration processing unit 43 can also generate the registered exhibit list so that the higher the presentation order determined by the presentation order determination unit 47, the higher the presentation position of the registered exhibit list.

In addition, when the registration processing unit 43 receives the comment request transmitted from the terminal device 2, the registration processing unit 43 acquires, from the exhibition information table, information on the comment related to the exhibit corresponding to the exhibition ID included in the comment request, and includes the acquired comment. The information on the comment screen is transmitted to the terminal device 2.

Upon acquiring the information on the comment screen, the display control unit 16 of the terminal device 2 displays a comment screen (not shown) based on the information on the comment screen. On the comment screen, a comment entered and registered by the exhibitor or a user U other than the exhibitor regarding the exhibited item corresponding to the exhibit ID included in the comment request is displayed.

The user U of the terminal device 2 can input a comment to the comment screen, and the comment thus input is transmitted to the auction item transaction processing device 1 by the processing unit 15 together with the auction ID. The registration processing unit 43 sets the comment transmitted from the terminal device 2 and the date and time of the comment in the “comment history” of the exhibition information table in association with the exhibition ID, and updates the comment number Nc of the “comment history”. , Update the listing information table.

In addition, the registration processing unit 43 can set the operation history of the share button 67 for each auction item in the share history (not shown) of the auction information table. In the share history for each exhibit, for example, the date and time when the share button 67 was operated, the user ID of the user U who operated the share button 67, and the number of times the share button 67 was operated (hereinafter referred to as the number of shares Ns). Yes) is included.

[2.3.4. Purchase processing unit 44]
The purchase processing unit 44 (see FIG. 4) receives the purchase request transmitted from the terminal device 2. When the purchase processing unit 44 receives the purchase request transmitted from the terminal device 2, the purchase processing unit 44 performs the purchase processing of the exhibited item corresponding to the purchase request. Such purchase processing is performed at the transaction price P at the time of purchase request.

For example, when the exhibition information table is in the state shown in FIG. 6 and there is a purchase request for the exhibit with the exhibition ID “C1”, the purchase processing unit 44 uses the current price “¥550” as the transaction price P to perform the purchase processing. I do. Such purchase processing is performed, for example, by credit card payment or electronic money payment. The purchase processing unit 44 ends the auction process of the auction item for which the purchase process has been performed, and excludes the auction item from the display target on the auction item list screen 61.

[2.3.5. Transaction price change unit 45]
When the transaction price change unit 45 (see FIG. 4) sets the transaction price P for each exhibit to the start price P _start based on the exhibit information table stored in the exhibit information storage unit 32, and then the exhibit is not purchased. In order to reduce the transaction price P, the transaction price P is gradually reduced. The process of gradually lowering the transaction price P is performed based on the information set in the auction information table.

The transaction price change unit 45 dynamically changes the process of gradually lowering the transaction price P of the exhibit whose price change setting is set to “present” in the exhibition information table, and the price change setting is set to “none”. The transaction price P of the set auction item is not reduced stepwise.

FIG. 9 is a diagram showing an example of changes in the transaction price P. In the example shown in FIG. 9, at each time t1, t2, t3, t4, and t5 at each predetermined time interval, the transaction price P gradually decreases with a predetermined decrease ΔP, and at time t5, the transaction price P changes. The minimum price is P _min . As described above, when the auction item is not purchased, the transaction price P is lowered stepwise. Therefore, for example, even when the setting of the transaction price P by the seller deviates from the desired price of the purchase examiner, it is possible to reduce the possibility that the exhibit is not purchased.

The transaction price change unit 45 may set the price change timings to unequal intervals, instead of setting the timings (hereinafter, referred to as price change timings) for lowering the transaction price P to equal intervals. .. For example, the transaction price change unit 45 can gradually reduce the interval of price change timing, and thereby can reduce the transaction price P in a quadratic curve. Thereby, for example, when approaching a desired period (for example, one day), the transaction price P can be drastically lowered, and the possibility that an exhibit is purchased can be increased.

Further, the transaction price changing unit 45 can also shorten the time period of the price change timing or the interval of the price change timing of the day of the week when the auction item is easily purchased. For example, the transaction price change unit 45 shortens the interval of price change timing in a time period or a day of the week when the auction item transaction processing service is frequently used, and sets the price change timing in a time period or a day of the week when the auction item transaction processing service is rarely used. The interval can be lengthened.

Further, based on the attention degree Da to be described later, the amount of information of exhibit information (explanation and image of the exhibit), the time zone, the transaction price P of the same or similar transaction target as the exhibit, etc. It is also possible to change the mode of gradually decreasing the transaction price P.

In addition, the transaction price changing unit 45 sets the lowest price P _min when the lowest price P _min is not set or when the seller releases (deletes) the lowest price P _min from the auction information table after the auction of the exhibit. The transaction price P can be gradually lowered to a fixed value regardless of P _min . As a result, the transaction price P can be made lower than the minimum price P _min when the state where the auction item is not purchased continues.

Further, the transaction price changing unit 45 can stop the process of lowering the transaction price P of the auction item whose presentation order is prioritized by the presentation order determination unit 47, or can reduce the decrease amount ΔP. It is possible to suppress the decrease and the degree of decrease of the transaction price P, and it is possible to prevent the profit of the seller from decreasing.

[2.3.6. Attention Determining Unit 46]
The attention degree determination unit 46 (see FIG. 4) determines the attention degree Da of the exhibited item based on, for example, the registration history, the comment history, the browsing history, and the share history included in the exhibition information table. The attention degree determination unit 46 stores the determined attention degree Da of each auction item in the auction information table. For example, the attention degree determination unit 46 can determine the attention degree Da of the exhibited item based on the registration number Ne, the comment number Nc, the browsing number Nv, and the share number Ns for the exhibited item.

For example, the attention level determination unit 46 can determine a value obtained by weighting and adding the number of registrations Ne, the number of comments Nc, the number of views Nv, and the number of shares Ns of the exhibited item as the attention level Da for the exhibited item. For example, the attention degree determination unit 46 can calculate the attention degree Da for the exhibited item based on the following equation (1). Note that K1 to K4 are coefficients for weighting.
Da=K1×Ne+K2×Nc+K3×Nv+K4×Ns (1)

The attention level determination unit 46 sets the determined attention level Da for each exhibited item in the auction information table. In the auction information table shown in FIG. 6, for example, "5.64" is set as the degree of attention for the item for sale with the item ID "C1", and "0.35" as the degree of attention for the item for sale with the item ID "C2". Is set. Here, the attention level Da is set in the range of 0 to 10, but the attention level Da is not limited to this range.

Further, the attention level determination unit 46 can set the number of comments set in the auction information table as the comment number Nc, and the number of comments set in the auction information table excluding the seller's comments. Can be used as the number of comments.

The attention degree determination unit 46 determines the attention degree Da by using the above formula (1) based on the registration number Ne, the comment number Nc, the browsing number Nv, and the share number Ns in the latest predetermined period (for example, one hour). It can be calculated for each period (for example, 10 minutes).

Further, the attention level determination unit 46 uses the above formula (1) based on the registration number Ne, the number of comments Nc, the number of views Nv, and the number of shares Ns per unit period in a state where the transaction price P does not change. The attention level Da can be calculated. The unit period is, for example, a period such as 10 minutes or 1 hour.

Further, based on the registration number Ne, the comment number Nc, the browsing number Nv, and the share number Ns that have occurred from the timing when the transaction price P is changed, the attention degree Da is calculated for each predetermined period using the above formula (1). You can That is, the attention degree determination unit 46 can calculate the attention degree Da based on the registration number Ne, the comment number Nc, the browsing number Nv, and the share number Ns for a certain transaction price P.

Note that the attention degree determination unit 46 can also calculate the attention degree Da for the exhibit based on one or more of the registration number Ne, the comment number Nc, the browsing number Nv, and the sharing number Ns. For example, the attention degree determination unit 46 can determine the value obtained by weighting and adding the registration number Ne and the browsing number Nv as the attention degree Da for the exhibited item.

In addition to or in place of the above-described information, the attention level determination unit 46 acquires an evaluation rank (for example, a five-step rank from A rank to E rank) indicating the evaluation of the exhibited item by the user U other than the exhibitor. However, the attention degree Da of the exhibited item can be determined based on the average value or the total value of the evaluation ranks.

Further, the attention degree determination unit 46 determines the attention degree of the exhibited article for each user U based on the attention degree Da of the exhibited article of the entire user U, the information of the exhibited article stored in the storage unit 21, and the information of the user U. The degree Dp can also be determined. In this case, the attention degree determination unit 46 stores the attention degree Dp of each auction item determined for each user U in the auction information table in association with each user ID.

The attention degree determination unit 46 can increase the attention degree Dp for each of the users U as the auction item that the user U is paying attention to (hereinafter referred to as a noticed auction item). For example, the attention level determination unit 46 increases the price of an item for sale (hereinafter referred to as a registered item for sale) registered by the user U using the registration button 65, and an item for sale browsed by the user U (hereinafter referred to as a browsed item for sale). ), the degree of attention Dp is increased. The registered exhibited item and the browse exhibited item are examples of the noticed exhibited item.

For example, the attention degree determination unit 46 can also determine the attention degree Dp of the exhibited item for each user U by the calculation of the following formula (2). In the following formula (2), "KA" is "1" when the exhibit is a registered exhibit, and "0" when the exhibit is not the registered exhibit. Further, “Npv” is the number of times browsed by the user U, and is the number of times for each user U. In equation (2) below, Dp1 and Dp2 are preset values. One of Dp1 and Dp2 may be 0.
Dp=Dp1×KA+Npv×Dp2 (2)

For example, when the exhibit A is registered by the user U ₁ and is viewed three times, the attention degree Dp of the exhibit A by the user U ₁ is Dp=Dp1+3×Dp2. Note that the calculation of the attention level Dp is not limited to the above expression (2), and can be changed as appropriate.

Furthermore, the attention level determination unit 46 can also determine the attention level Dp of the exhibited item for each user U based on not only the exhibited item of interest but also the exhibited item that is similar to the exhibited item of interest. For example, the attention degree determination unit 46 can increase the attention degree Dp as the attention item determination unit 46 is closer to the noticed item.

The attention level determination unit 46 determines the product category of each exhibited item based on the information (the item name of the exhibited item, the description of the item, and the image of the item) set in the exhibited item information table. The attention level determination unit 46 determines the degree of similarity between each exhibited item and the exhibited item on the basis of the determined product category and the similarity determination table (not shown) stored in the storage unit 21.

The similarity between the product categories is set in the similarity determination table, and the attention level determination unit 46 determines the attention level based on the product category of the exhibited item of interest and the product category of the exhibited item of interest determination target. It is possible to determine the similarity of the target exhibit. The product category is, for example, a product model, product name, product category, or the like. In addition, when the item of interest determination target is the item of interest, the similarity to the item of interest is 100%.

The attention degree determination unit 46 can set the attention degree Dp of each auction for each user U based on the degree of similarity of the auction for each exhibited article. For example, it is assumed that the attention degree determination unit 46 has two attention exhibition items A and B of the user U ₁ , and the attention degrees Dp of the respective attention exhibition items A and B are DpA and DpB. Further, the degree of similarity of the exhibited item C with the noticed exhibited items A and B is X% and Y%, respectively. In this case, the attention degree determination unit 46 can obtain the attention degree DpC of the exhibited item C by the calculation of the following formula (3).
DpC=(X×DpA+Y×DpB)/2 (3)

In this way, the attention degree determination unit 46 can multiply the attention degree of each attention exhibition item by the similarity degree of each exhibition item, and set the average value of the multiplication results as the attention degree Dp of each exhibition item. For each user U, the higher the degree of similarity with the noted auction item is, the more the degree of interest Dp of the auction item can be calculated, and the method of calculating the degree of attention Dp of each auction item described above is not limited.

When the user U (for example, the user U ₂ ) pays attention to the auction item (hereinafter referred to as the purchased noticed auction item), the attention degree determination unit 46 determines that the user U (for example, the user U ₂ ). Exclude from the noticed exhibit that is the noticed exhibit. Thereby, the degree of attention Dp is set to be higher for an exhibit exhibiting a higher similarity to an exhibit (hereinafter, referred to as an unpurchased notice exhibit) which the user U (for example, the user U ₂ ) pays attention to and has not purchased. You can Therefore, it is possible to prevent the attention degree Dp of the auction item that is the same as or similar to the auction item that the user U has already purchased and has stopped paying attention to from increasing.

Further, the attention level determination unit 46 may lower the attention level Dp of the purchased attention exhibition item with respect to the unpurchased attention exhibition item without excluding the purchased attention exhibition item from the attention exhibition item. For example, the attention level determination unit 46 significantly lowers the attention level Dp at the timing of purchase in the case of a particular exhibited item such as a consumable item that is already purchased and has been purchased. After that, the attention level Dp can be increased with the passage of time.

[2.3.7. Presentation order determination unit 47]
The presentation order determination unit 47 (see FIG. 4) can determine the presentation order of the exhibited item for each array condition for determining the presentation order of the exhibited item. The arrangement conditions include the above-mentioned conditions of new arrival order, attention order, attention adjustment order, new arrival adjustment order, and the like. Hereinafter, each array condition will be described.

[2.3.7.1. New arrival order]
First, the case where the arrangement condition is the new arrival order will be described. The presentation order determination unit 47 determines the presentation order in order from the newest exhibition start date and time set in the exhibition information table every time the exhibition information is added to the exhibition information table. That is, the presentation order determination unit 47 determines the presentation order of the auction item so that the auction item having a newer exhibition start date has a higher presentation order (a smaller number).

As a result, the browsing processing unit 42 can generate the information of the new listing item listing screen 61 whose presentation position is higher in the newer listing start date and time, and can transmit the information to the terminal device 2. The display control unit 16 of can display the exhibit list screen 61 in the order of new arrivals. It should be noted that the presentation order determination unit 47 can also determine the presentation order in order from the item with the oldest exhibition start date and time, whereby the browsing processing unit 42 has the highest presentation position from the item with the oldest exhibition start date and time. It is possible to generate information on the exhibit list screen 61 in the order of first-come-first-served basis and send it to the terminal device 2.

[2.3.7.2. Order of attention]
Next, the case where the arrangement conditions are in the order of interest will be described. Every time the attention degree Da of the exhibition information table is updated, the presentation order determination unit 47 determines the presentation order in descending order of the attention degree Da set in the exhibition information table. That is, the presentation order determination unit 47 determines the presentation order of the auction item so that the auction item having a higher attention level Da has a higher presentation order.

As a result, the browsing processing unit 42 can generate the information of the exhibit list screen 61 in the attention order in which the presentation position is higher in the exhibit with the higher attention level Da, and can transmit the information to the terminal device 2. The display control unit 16 can display the exhibit list screen 61 in the order of attention. It should be noted that the presentation order determination unit 47 can also determine the presentation order of the exhibited items in descending order of the attention degree Da, whereby the browsing processing unit 42 has a higher presentation position for the exhibited items having a lower attention degree Da. It is possible to generate the information of the exhibit list screen 61 in the order of attention, and send it to the terminal device 2.

Although the presentation order determination unit 47 determines the presentation order in the order of attention of each exhibited item based on the attention degree Da, the presentation order determination unit 47 determines the presentation order in the attention order of each exhibited item based on the attention degree Dp for each user U. You can also do it. In this case, every time the attention degree Dp of the auction information table is updated, the presentation order determination unit 47 makes the presentation order of the exhibited items such that the exhibition order of the exhibited items is higher for the user U with a higher attention level Dp. To decide. That is, the presentation order determination unit 47 can determine the presentation order of the auction item for each user U such that the auction item having a higher attention level Dp has a higher presentation order.

As a result, the browsing processing unit 42 generates, for each user U of the browsing request source, information on the listing product screen 61 in the order of attention, in which the higher the attention level Dp is, the higher the presentation position is, and the higher the presentation position is, the higher the presentation position is. The display control unit 16 of the terminal device 2 can display the exhibit list screen 61 in the order of attention corresponding to each user U. It should be noted that the presentation order determination unit 47 can also determine the presentation order of the exhibited items in descending order of the attention degree Dp.

[2.3.7.3. Attention adjustment order)
Next, a case where the arrangement condition is the attention adjustment order will be described. Every time the attention degree Da of the exhibition information table is updated, the presentation order determination unit 47 tentatively determines the presentation order in descending order of the attention degree Da set in the exhibition information table. That is, the presentation order determination unit 47 tentatively determines the presentation order of the auction item so that the auction item having a higher degree of attention Da has a higher presentation order.

Then, the presentation order determination unit 47 adjusts the provisionally determined presentation order based on the downward width ΔP of the transaction price P of the auction item, and finally determines the presentation order of the auction item. That is, the presentation order determination unit 47 finally determines the presentation order to be higher than the tentatively determined presentation order by the number of carry-ups according to the magnitude of the downlink width ΔP.

For example, the presentation order determination unit 47 obtains the carry number Na by the calculation of the following formula (4). In the following formula (4), “INT” is an integer function and K5 is a coefficient for weighting.
Na=INT(K5×ΔP) (4)

Then, the presentation order determination unit 47 finally determines the presentation order of the exhibited item by the calculation of the following formula (5). In the formula (5) below, “Np” is a provisionally determined presentation order, and “Nc” is a finalized presentation order.
Nc=Np+Na (5)

As a result, the browsing processing unit 42 can generate information of the exhibit list screen 61 in which the presentation order in the order of attention is moved up to the upper position in accordance with the downward width ΔP of the transaction price P, and can be transmitted to the terminal device 2. The display control unit 16 of the terminal device 2 can display the exhibit list screen 61 in the attention adjustment order. Therefore, when the descending width ΔP of the exhibited item is high, the presentation order of the exhibited item can be advanced to a higher position than the presentation order based on the attention degree Da only, and the transaction price P is set to be gradually decreased. You can increase the likelihood that an item will be purchased.

Note that the presentation order determination unit 47 secures a higher presentation order (hereinafter, referred to as a dedicated presentation order) for an exhibit whose downlink width ΔP is equal to or more than a predetermined value, and the downlink width ΔP is equal to or more than a predetermined value in the dedicated presentation order. It is also possible to allocate the auction item to the higher rank as the descending width ΔP is larger. In addition, the presentation order determination unit 47 sets the presentation order of the exhibited items whose downlink width ΔP is equal to or more than a predetermined value so that the probability that the exhibited item whose downlink width ΔP is equal to or more than a predetermined value is assigned to the dedicated presentation order is higher as the downlink width ΔP is larger. Assignments can also be made.

In addition, the presentation order determination unit 47 presents the presentation order of the exhibited items in descending order of the score Sa (hereinafter, referred to as the attention adjustment score Sa) calculated based on the attention degree Da and the downlink width ΔP set in the exhibition information table. Can be determined. For example, the attention adjustment score Sa can be obtained by the calculation of the following formula (6). K6 is a coefficient for weighting.
Sa=K4×Da+K6×ΔP (6)

The presentation order determination unit 47 determines the presentation order in descending order of the attention adjustment score Sa. That is, the presentation order determination unit 47 determines the presentation order of the auction item so that the auction item has a higher presentation order as the attention adjustment score Sa is higher. As a result, the browsing processing unit 42 can generate the information of the auction item list screen in which the auction items are arranged at the presentation position corresponding to the presentation order according to the attention adjustment score Sa, and transmit the information to the terminal device 2.

Further, the downlink width ΔP used in the above equations (4) and (6) is the difference in fluctuation of the transaction price P before and after one fluctuation, for example, ΔP=P _d1 −P _d2 (see FIG. 9). .. Further, the downward width ΔP may be a fluctuation difference of the transaction price P in a predetermined period, for example, ΔP=P _d1 −P _d3 (see FIG. 9) or ΔP=P _d1 −P _d4 (see FIG. 9). is there. Further, the downward width ΔP may be a fluctuation difference of the transaction price P from the start price P _start , for example, ΔP=P _start −P _d3 (see FIG. 9) or ΔP=P _start −P _d4 (FIG. 9). See).

Further, in the above-described example, the presentation order determination unit 47 has been described as an example in which the higher the attention level Da is, the higher the presentation order is. However, the presentation order determination unit 47 determines the presentation order of the exhibited items in order from the lowest attention level Da. You can also do it. In this case, the presentation order determination unit 47 replaces “K4×Da” with “K4/Da” in Expression (4) to calculate the attention adjustment score Sa.

Further, the presentation order determination unit 47 determines the presentation order of the attention adjustment order of each exhibit based on the attention degree Da. However, the presentation order of the attention adjustment order of each exhibit based on the attention degree Dp for each user U. Can also be determined. In this case, the presentation order determination unit 47 replaces the “attention degree Da” with the “attention degree Dp” for each user U, and performs the above-described processing, whereby the attention adjustment order of the exhibited items for each user U is determined. It is also possible to determine the presentation order.

For example, each time the attention level Dp of the auction information table is updated, the presentation order determination unit 47 tentatively determines the presentation order for each user U in the descending order of the attention level Dp set in the auction information table. That is, the presentation order determination unit 47 tentatively determines, for each user U, the presentation order of the auction item so that the auction item having a higher attention level Dp has a higher presentation order.

Then, the presentation order determination unit 47 adjusts the provisionally determined presentation order for each user U based on the downward width ΔP of the transaction price P of the auction item, and finally determines the presentation order of the auction item. That is, the presentation order determination unit 47 makes the main determination of the presentation order for each user U so that the presentation order is higher than the provisionally determined presentation order by the number of moves according to the size of the downlink width ΔP. Accordingly, the presentation order of the attention adjustment order of the exhibited items can be determined for each user U based on the attention degree Dp.

[2.3.7.4. New arrival order]
Next, a case where the arrangement condition is the new arrival adjustment order will be described. Every time the exhibition information is added to the exhibition information table, the presentation order determination unit 47 tentatively determines the presentation order in descending order of the exhibition start date and time set in the exhibition information table. That is, the presentation order determination unit 47 tentatively determines the presentation order of the auction item so that the auction item having a newer exhibition start date has a higher presentation order.

Then, the presentation order determination unit 47 adjusts the provisionally determined presentation order based on the attention level Da, and finally determines the presentation order of the exhibited item. That is, the presentation order determination unit 47 finally determines the presentation order such that the presentation order is higher than the provisionally determined presentation order by the number of advance according to the attention level Da.

For example, the presentation order determination unit 47 obtains the carry number Na by the calculation of the following formula (7). In the following equation (7), “INT” is an integer function and K7 is a coefficient for weighting.
Na=INT (K7×Da) (7)

Then, the presentation order determination unit 47 finally determines the presentation order of the auction item by the calculation of the equation (5). As a result, the browsing processing unit 42 can generate the information of the exhibit list screen 61 in which the presentation order of the new arrival order is moved up to the higher order according to the attention level Da, and can transmit the information to the terminal device 2, and the terminal device 2 The display control unit 16 can display the exhibit list screen 61 in the new arrival adjustment order.

Therefore, when the attention level Da is high, the presentation order of the exhibited item can be moved up to a higher position than the presentation order based on the freshness of the exhibition start date and time, and the transaction price P is set to be gradually lowered. You can increase the likelihood that an item will be purchased.

Further, the presentation order determination unit 47 presents the order of presentation of the exhibited items in descending order of the score Sn (hereinafter referred to as the new arrival adjustment score Sn) calculated based on the exhibition start date and time and the attention level Da set in the exhibition information table. Can be determined. For example, the new arrival adjustment score Sn can be obtained by the calculation of the following formula (8). In the following formula (8), “To” is an elapsed time from the exhibition start date and time, and K8 and K9 are weighting coefficients.
Sn=K8/To+K9×Da (8)

The presentation order determination unit 47 determines the presentation order in descending order of the new arrival adjustment score Sn. That is, the presentation order determination unit 47 determines the presentation order of the auction item so that the auction item has a higher presentation rank as the new arrival adjustment score Sn is higher. As a result, the browsing processing unit 42 can generate the information of the auction item list screen in which the auction items are arranged at the presentation position corresponding to the presentation order according to the new arrival adjustment score Sn, and transmit the information to the terminal device 2.

Further, in the above-described example, the presentation order determination unit 47 has described an example in which the presentation order becomes higher as the exhibition start date and time is newer. However, the presentation order of exhibit items is determined in descending order of the exhibition start date and time. You can also do it. In this case, for example, the presentation order determination unit 47 replaces “INT(K7×Da)” with “INT(K7/Da)” in (5) above to calculate the carry number Na, and then the equation (6) above. In, the “K8/To” is replaced with “K8×To” to calculate the new arrival adjustment score Sn.

Further, the presentation order determination unit 47 determines the presentation order of the new arrival adjustment order of each exhibit based on the attention degree Da, but the presentation order of the new arrival adjustment order of each exhibit based on the attention degree Dp for each user U. Can also be determined. In this case, the presentation order determination unit 47 replaces the “attention degree Da” with the “attention degree Dp” for each user U, and performs the above-described processing, whereby the new arrival adjustment order of each exhibited item is displayed for each user U. The presentation order can be determined.

For example, the presentation order determination unit 47 adjusts the presentation order provisionally determined in the new arrival order based on the attention level Da, and finally determines the presentation order of the exhibited item. That is, the presentation order determination unit 47 finally determines the presentation order to be higher than the provisionally determined presentation order by the number of advancements according to the attention level Dp. Thereby, the presentation order of the new arrival adjustment order of each auction item can be determined for each user U based on the attention degree Dp.

[2.3.7.5. Other array conditions]
The arrangement conditions are not limited to the conditions of the new arrival order, the attention order, the attention adjustment order, and the new arrival adjustment order described above. The presentation order determination unit 47 can determine the presentation order of the price adjustment order or the evaluation adjustment order by the same processing as in the case of the attention adjustment order or the new arrival adjustment order.

For example, the presentation order determination unit 47 tentatively determines the presentation order of the exhibited items in the descending order of the transaction price P of the exhibited item, and the provisionally determined presentation order is the attention degree Da (or the attention degree Dp) of the exhibited item. It is possible to make a final decision on the presentation order of the exhibited items by making adjustments based on. In addition, the presentation order determination unit 47 tentatively determines the presentation order of the auction item in the descending order of the transaction price P of the auction item, and adjusts the provisionally determined presentation order based on the descending width ΔP of the auction item. It is possible to make a final decision on the presentation order of the objects.

As a result, the browsing processing unit 42 generates information of the exhibit list screen 61 in which the presentation order in the price order is moved up to the higher order according to the attention degree Da (or the attention degree Dp) and the downward width ΔP, and the terminal device 2 The display control unit 16 of the terminal device 2 can display the exhibit list screen 61 in the price adjustment order. Therefore, for example, even when there are a plurality of exhibit items with the same price, it is possible to move up to a higher position based on the attention level Da (or the attention level Dp) and the downward width ΔP, and an excessive decrease in the transaction price is suppressed. In addition, it is possible to improve the possibility that the exhibit is purchased.

In addition, the presentation order determination unit 47 tentatively determines the presentation order of the exhibited article or the exhibitor in the descending order of the average value or total value of the evaluation ranks of the exhibitor and the tentatively determined presentation order. The presentation order of exhibited items can be finally determined by adjusting based on Da (or attention level Dp). In addition, the presentation order determination unit 47 tentatively determines the presentation order of the exhibited items in descending order of the average value or the total value of the evaluation ranks of the exhibited item or the exhibitor, and the provisionally determined presentation order is the descending width of the exhibited item. The presentation order of the exhibited items can be finally determined by adjusting based on ΔP.

As a result, the browsing processing unit 42 displays the information of the exhibit list screen 61 in which the presentation order of the exhibit or the exhibitor in the evaluation order is moved up to the upper position according to the attention degree Da (or the attention degree Dp) or the downhill width ΔP. It can be generated and transmitted to the terminal device 2, and the display control unit 16 of the terminal device 2 can display the exhibit list screen 61 in the evaluation adjustment order. Therefore, for example, even the exhibited items of the same evaluation rank (average value or total value) can be moved up to the higher position based on the attention degree Da (or the attention degree Dp) or the downward width ΔP, and the transaction price P It is possible to suppress the excessive decrease and improve the possibility that the exhibit is purchased.

In the above-described example, similarly to the case of the new arrival adjustment order or the attention adjustment order, the presentation order of the price order or the evaluation order is moved up to the higher rank according to the attention degree Da (or the attention degree Dp) or the downhill width ΔP. Although the example of determining the presentation order has been described, the presentation order can be determined by a score obtained by weighting and adding the price order or the evaluation order and the attention degree Da (or the attention degree Dp) or the downlink width ΔP.

[3. Processing Flow of Exhibit Transaction Processing Device 1]
First, an example of an information processing procedure in the auction item transaction processing apparatus 1 will be described with reference to FIG. 10. FIG. 10 is a flow chart showing an example of the flow of information processing in the exhibition transaction processing apparatus 1.

As shown in FIG. 10, the control unit 22 determines whether or not a request (for example, an auction request, an additional setting request, a setting cancellation request, etc.) regarding the auction of the auctioned item has been received from the terminal device 2 (step S10). When it determines with having received the request|requirement regarding the exhibition of the exhibited item (step S10; Yes), the control part 22 performs the process regarding the exhibition of the exhibited item (step S11).

When it is determined that the request for selling the auction item has not been received (step S10; No), or when the process of step S11 ends, the control unit 22 determines, based on the information set in the auction information table. The attention level Da is determined (step S12). The control unit 22 determines the degree of attention Da of the exhibited item based on, for example, the number of registrations Ne, the number of comments Nc, the number of views Nv, and the number of shares Ns included in the auction information table.

Further, the control unit 22 determines the presentation order of the exhibited items for each arrangement condition (step S13). For example, the control unit 22 can determine the presentation order of the exhibited item for each condition of new arrival order, attention order, attention adjustment order, and new arrival adjustment order.

When the process of step S13 is completed, the control unit 22 determines whether or not there is a list request from the terminal device 2 (step S14). When it is determined that there is a list request (step S14; Yes), the control unit 22 generates information of the exhibit list screen 61 corresponding to the list request (step S15). This process is the process of steps S20 to S22 shown in FIG. 11, and will be described in detail later. After generating the information of the exhibit list screen 61, the control unit 22 transmits the generated information of the exhibit list screen 61 to the requesting terminal device 2 (step S16).

When it is determined that there is no list request (step S14; No), or when the process of step S16 ends, the control unit 22 determines whether it is the price change timing (step S17). The control unit 22 determines that it is the timing of price change, for example, when the decrease interval ΔT of the transaction price P arrives. The process of step S17 is executed by the transaction price changing unit 45.

When it is determined that it is the price change timing (step S17; Yes), the control unit 22 performs a price change process (step S18). The price change process is a process executed by the transaction price change unit 45 described above, and includes, for example, a process of determining whether or not to change the transaction price P, a process of determining a decrease ΔP of the transaction price P, and The transaction price P is updated and the like.

When it is determined that it is not the price change timing (step S17; No), or when the process of step S18 ends, the control unit 22 performs another process (step S19). For example, in step S19, the control unit 22 can execute the other processing described above by the browsing processing unit 42 and the processing by the registration processing unit 43 or the purchase processing unit 44.

FIG. 11 is a diagram showing an example of the process of step S15 shown in FIG. As illustrated in FIG. 11, the control unit 22 determines whether or not the list request transmitted from the terminal device 2 includes the information designating the arrangement condition (step S20).

When it is determined that the list request does not include the information designating the delivery condition (step S20; Yes), the control unit 22 arranges the exhibits at the presentation position (arrangement position) corresponding to the presentation order in the new arrival order. The information of the exhibit list screen 61 in the order of new arrival is generated (step S21).

When it is determined that the list request includes the information specifying the delivery condition (step S20; No), the control unit 22 displays the item at the presentation position (array position) according to the presentation order specified by the array condition. The information of the exhibit list screen 61 corresponding to the arrangement condition in which the items are arranged is generated (step S22).

[4. Modification example)
In the above-described embodiment, the control unit 22 of the exhibition product transaction processing apparatus 1 specifies the presentation positions in the presentation order according to the arrangement conditions to generate the exhibition product list screen 61. Similarly, the browsing processing unit 42 can also specify the presentation position in the presentation order according to the arrangement condition and generate the evaluation exhibit list.

Further, the presentation order determination unit 47, for example, provisionally determines the presentation order in the new arrival order, adjusts the presentation order so that the auction item that the user U is paying attention to is carried forward, and further, the larger the descending width ΔP is, It is also possible to determine the presentation order by making the presentation order move up.

In addition, the presentation order determination unit 47 can determine the presentation order of the exhibited items so that the presentation orders do not overlap, and also determine the presentation order of the exhibited items so that the presentation orders overlap by a predetermined number. You can

Further, in the above-described embodiment, the presentation order is advanced according to the reduction amount ΔP of the transaction price P, but the presentation order determination unit 47 can advance the presentation order according to the number of reductions of the transaction price P. For example, the presentation order determination unit 47 can increase the carry-over number Na as the number of times the transaction price P is lowered. Further, the presentation order determination unit 47 can increase the carry-over number Na as the amount of decrease ΔP is larger and the number of times the transaction price P is decreased.

[6. effect〕
The exhibit transaction processing device 1 according to the embodiment includes an exhibition acceptance unit 41 (an example of an acceptance unit), a transaction price change unit 45, a presentation order determination unit 47, and a browse processing unit 42 (an example of a distribution unit). .. The exhibition acceptance unit 41 accepts the setting of the transaction price P of the exhibit. The transaction price changing unit 45 gradually lowers the transaction price P. The presentation order determination unit 47 determines the presentation order of the exhibited item based on the degree of attention to the exhibited item whose transaction price P is lowered by the transaction price change unit 45. As a result, it is possible to improve the possibility that the auction item is purchased while suppressing an excessive decrease in the transaction price.

In addition, the browsing processing unit 42 (an example of a distribution unit) distributes information on the auction item (for example, the auction item list screen) to the terminal device 2 in the presentation order determined by the presentation order determination unit 48, or determines the presentation order. Information on the presentation order determined by the unit 48 can be distributed to the terminal device 2. As a result, since the exhibited item for which the sales promotion is set can be preferentially presented to the user U of the terminal device 2 in the higher presentation order, the exhibited item can be purchased while suppressing an excessive decrease in the transaction price P. It is possible to improve the sex.

Moreover, the higher the degree of attention of the auction item, the presentation order determination unit 47 gives a higher priority to the presentation order of the auction item. As a result, the higher the degree of attention, the higher the rank of presentation, so that it is possible to improve the possibility that an exhibit having a high degree of attention will be purchased.

Further, the auction item transaction processing apparatus 1 includes an attention level determination unit 46. The attention degree determination unit 46 determines the attention degree of the auction item based on at least one of the number of browsed items for sale, the number of registered items for sale, and the evaluation rank of the item for sale. As a result, it is possible to appropriately determine the degree of attention of the exhibited item, and it is possible to improve the possibility that the exhibited item having a high degree of attention will be purchased.

In addition, the presentation order determination unit 47 determines the presentation order of the exhibited item based on the fluctuation of the transaction price P of the exhibited item and the attention degree Da. As a result, the order of presentation is determined in consideration of the fact that the transaction price P has declined in a state where the auction item has not been purchased continuously, and thus the auction item is displayed to the user U of the terminal device 2 in the arrangement order of only the attention degree Da. Compared with the case of presenting, the exhibited item whose transaction price fluctuates can be effectively presented to the user U of the terminal device 2.

Further, the presentation order determination unit 47 raises the presentation order of the auction item based on the fluctuation of the transaction price P, while making the presentation order of the auction item higher as the attention degree Da is newer. As a result, the exhibited item whose transaction price P has changed can be effectively presented to the user U of the terminal device 2. Further, the more the transaction price P fluctuates, the higher the order of presentation is. Therefore, the more the transaction price P fluctuates, the higher the chance of purchase.

In addition, the presentation order determination unit 47 raises the presentation order of the auction item based on the attention degree Da of the auction item while raising the presentation order of the auction item as the exhibition start date and time of the auction item is newer. As a result, even if the presentation position becomes a lower position with the lapse of time, in the case of an exhibit having a high degree of attention Da, the presentation position is moved up, so that the transaction price P is excessively lowered. It is possible to improve the possibility that an exhibit is purchased while suppressing the above.

Further, the higher the transaction price P is, or the lower the transaction price P is, the higher the presentation order of the auction item is, and the higher the transaction price P is, the higher the transaction order P is. As a result, when the attention level Da of the exhibited item is high in the presentation order in the price order, the presented position is moved up, and thus the possibility of purchasing the exhibited item is improved while suppressing an excessive decrease in the transaction price P. Can be made.

In addition, the exhibited item transaction processing device 1 includes a storage unit 21 that stores information on exhibited items that each user U has focused on. The presentation order determination unit 47 has a high degree of similarity with the auction item (for example, the aforesaid auction item described above) focused on by the user U (for example, the user U of the terminal device 2 that is the browse request source) who is the presentation destination of the auction item. The presentation order of the exhibited items is given higher priority. As a result, it is possible to give priority to the presentation order of the auction item having a high degree of attention for each user U, and increase the possibility of purchasing the auction item.

In addition, the presentation order determination unit 47 gives higher priority to the presentation order for the auction item that has a higher degree of similarity with the auction item that has not been purchased by the user U who is the presentation destination of the auction item. As a result, it is possible to increase the possibility that the auction item that the user U is paying attention to is purchased.

In addition, the presentation order determination unit 47 excludes the auction item that the user U who is the presentation destination pays attention to and has purchased from the exhibited item that the user U who is the presentation destination of the auction item pays attention to. As a result, it is possible to prevent the user U from paying attention to the past but presently exhibiting items that are less likely to be purchased in a higher ranking, and increase the possibility that items are purchased. ..

Each of the above-mentioned exhibit transaction processing apparatus 1 may be realized by a plurality of server computers, and depending on the function, an external platform or the like may be realized by calling an external platform by API (Application Programming Interface) or network computing. The configuration can be changed flexibly.
