Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to the method of Internet auctions, especially for properties that are likely to be valued, such as old books, and hesitates to exhibit but wants to exhibit but does not know the valid market price, preventing the distribution of these properties Technology to solve the situation.
[0002]
[Prior art]
In the conventional Internet auction, an auction server that provides an auction site, a general member client that registers an exhibition property, and a general member or a non-member client that participates in an auction of these exhibition properties and bids are connected via the Internet. Become. Here, a conventional auction method will be described with reference to FIG.
[0003]
As shown in FIG. 7 (a), there are two types of auctions: auction type (a-1) and auction type (a-2). In the auction, various prices are set by sellers and bidders. In the case of the auction type, as shown in FIG. 7 (a-1), an auction server presents an auction start price S1 and an auction minimum price M, and the auction starts at the auction price. Starting from S1, if there are no bidders for a certain period, the auction server presents a new price that has been auctioned in a certain mode (for example, lowering by 500 yen every two days) and solicits a bid at that price. Such auctions are repeated, and when a bid is first made at the offer price, a successful bid is determined and the process ends (the successful bid determined price x at the time of the auction). At the time of the auction expiration, or when the offer price reaches a predetermined minimum price (the lowest price at the time of auction M), if there is no bid, the process ends without a successful bid.
[0004]
On the other hand, in the auctioning ceremony, as shown in FIG. 7 (a-2), the auction starting bid price S2 is presented to the client by the auction server. The successful bid is determined by the highest bid price at the expiration of the auction due to the auctioning bid, and the bid is completed (successful bidding successful bid determined price y). If there are no bids until the auction time limit, the process ends without a successful bid.
[0005]
In this way, in executing an auction, a price initially provided from an auction server and a price for controlling an auction such as a lowest price at the time of auction are referred to as an auction price in this specification. That is, the auction price is a generic name of the bid start price S1 at the time of auction, the minimum price M at the time of auction, and the bid start price S2 at an auction.
[0006]
Also, auction sellers usually have a feeling that they will be worth this price when selling the property, or that they do not want to sell below this price. In the present specification, such a price based on the emotions of the seller is referred to as an emotional price. That is, as shown in FIG. 7 (b), the sentiment price is the price that the exhibitor expects the exhibited property to be worth this price (hereinafter, referred to as a reasonable sentiment price), and The exhibited property is a generic term for a price that the user does not want to sell below this price (hereinafter, referred to as a lower emotional price).
[0007]
Conventional Internet auctions cover a variety of properties such as coupons, furniture, and electrical products, but in most cases, the general members who exhibit the property specify the above auction price based on their own emotional prices. Register For example, as shown in FIG. 7 (c), the bid start price S1 at the time of auction is set at a reasonable emotional price U or a price higher than it, and the minimum price M at the time of an auction is set by the lower emotional price L by the exhibitor. In the case of the bid start price S2 at the time of auction, the exhibitor specifies the lower limit emotion price L.
[0008]
However, for properties that are likely to be valued, such as old books, and that the seller wants to exhibit but does not know the legitimate market price, although it has its own emotional price, it may differ from the market price In many cases, it is difficult for general members to specify the auction price, and hesitate to exhibit. For this reason, many of these properties are sleeping in ordinary households. For example, it is possible to bring them to a reputable used bookstore for consultation, but it is difficult to bring them to the used bookstore because of the labor and troublesome work of searching for, relocating and negotiating such used bookstores. .
[0009]
Patent Literature 1 below discloses an Internet auction in which an expert evaluates a legitimate market price in order to improve the distribution of home-sleeping properties using IT technology.
[0010]

[0011]
[Problems to be solved by the invention]
However, in the Internet auction described in Patent Document 1, it is necessary to establish a large-scale organization such as establishment of a mechanism for certifying product assessment qualifications, and it is thought that there is no prospect of realization in the near term. In addition, it is not possible to obtain the evaluation price evaluated by experts unless after the exhibition decision, and it is unknown how the evaluation price is related to the emotional price and the auction price, and it is still inspiring general members' willingness to exhibit It is not something to do.
[0012]
The present invention has been made in view of such a situation, and is an article which is likely to be valued such as an old book, and is intended to exhibit but wants to exhibitor's willingness to exhibit because he does not know the valid market price. The aim is to realize an Internet auction system that inspires and promotes the distribution of these properties.
[0013]
[Means for Solving the Problems]
Conventionally, the above-mentioned problem that an exhibitor wants to exhibit but hesitates to exhibit because he does not know a valid market price is solved by the auction price determination method of the present invention shown in FIGS.
That is, in the present invention, as an example of the operation flow of the auction server AS as shown in FIG. 2, an operation flow of the auction server AS is illustrated in FIG. An auction price determination method in an Internet auction system in which an expert member client PC that evaluates an auction is connected to the auction server AS via the Internet, and registers a seller's emotional price (included in the property information BI) for the listing candidate property. 1 (step S13 in FIG. 1), a step of registering the evaluation price (included in the evaluation information EI) of the expert member for the exhibition candidate property (step S24), and a step of registering the sentiment price and the evaluation price. , Determining the exhibited property and its auction price (step S And 1 to 42), to solve by auction pricing method with the.
[0014]
Furthermore, if the auctioned property whose auction price is determined based on this evaluation price is not awarded by executing the auction, the expert member who has registered the evaluation price of the auctioned property is a price at which the expert member wins the auctioned property. The above problem is more effectively solved by having the step of determining the house member successful bid price (step S43).
[0015]
Further, when an exhibit for which an auction price based on the evaluation price is determined is awarded by executing an auction, an evaluation fee, which is a fee received by the expert member who has registered the evaluation price of the exhibit, is calculated ( The above problem is more effectively solved by having step S52).
Hereinafter, the operation of the problem solving means in an auction business model using a system in which the auction price determination method as shown in FIGS.
[0016]
The business operator who establishes the auction server AS recruits general members to be exhibited, as well as recruits expert members who are experts in the property field in the conventional manner. The general member having the exhibition candidate article registers this together with the emotional price in the exhibition candidate database CDB of the auction server AS (steps S11 to S13), and waits for the evaluation price from the expert member. In the auction server AS, the exhibition candidate article is disclosed to the expert member with the emotional price hidden, and the evaluation price registration from the expert member client PC is received within a certain evaluation period (steps S21 to S24). The received evaluation price is stored in the exhibition candidate article database CDB.
[0017]
When the predetermined evaluation period has come, the exhibition property determination means 3 of the auction server AS searches the exhibition candidate property database CDB, and determines a property i to be exhibited in consideration of the emotional price and the evaluation price of these exhibition candidate properties ( In step S41, the property-related information is extracted as exhibited property data SD (i). Since the auction price of these properties to be exhibited is determined in consideration of the evaluation price in accordance with the emotional price of the seller (step S42), the willingness of the seller to hesitate to exhibit without knowing the market price is strongly inspired. You can do it.
[0018]
Furthermore, even if the property is closed without being sold in the auction execution, depending on the value of the evaluation price that contributed to the formation of the auction price, the expert member that provided this evaluation price may not If there is a promise to accept this in advance, it is possible to eliminate the failure to make a successful bid due to an evaluation price that is too high, so that the seller's willingness to exhibit without knowing the market price can be further inspired.
[0019]
Furthermore, if the property member has been promised to pay a predetermined evaluation fee to the expert member who has registered the evaluation price for the exhibited property when the property is awarded by executing the auction, the expert member will be It is thought to be an incentive to give an appropriate evaluation price, which can further inspire the seller's willingness to sell the product.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the auction price determination method of the present invention will be described with reference to FIGS. Note that the computer processing according to the present invention is executed by a computer program developed on a main storage device of the computer, and the providing form of the computer program includes an auxiliary storage device connected to the computer, a CD-ROM, and the like. It is provided by being stored in a recording medium such as a portable storage device such as a ROM or a main storage device and an auxiliary storage device of another network-connected computer. It is loaded on a storage device and executed.
[0021]
FIG. 2 shows an embodiment of the auction server AS for realizing the auction price determination method of the present invention. The auction server AS is connected to the general member client GC, the expert member client PC, and the general member or non-member client OC via the Internet. Here, it is assumed that the general member client GC accesses the auction server AS in order for the general member to register an exhibition candidate property. This is described as access 1 in FIG. The expert member client PC accesses the expert member in order to register the evaluation price for the exhibit candidate property. This is described as access 2 in FIG. It is assumed that the general member or non-member client OC accesses the auction server AS in order to bid on the exhibited property. This is described as access 3 in FIG.
[0022]
The auction server AS registers the property information BI corresponding to the access 1 in the property candidate database CDB, and the evaluation price registration means 2 registers the evaluation information EI corresponding to the access 2 in the property candidate database CDB. An exhibition property determination means 3 for determining an exhibition property from the exhibition candidate property database CDB and buffering it as exhibition property data SD (i); bidding information n for a property i from a general member or a non-member client OC corresponding to the access 3 (i), the bidding history nr (i) is updated, the exhibited property data SD (i) and the bidding history nr (i) are displayed as auction data AD (i), and other general member or non-member client OCs are displayed. Executing means 4 for receiving bid information n (i) from auction, an auction manager controlling an auction environment Step 5, post-sale processing means 6 for supporting the payment of money with the successful bidder of the auction, and unsuccessful bids for supporting transactions between exhibitors and evaluation specialist members related to the property that has ended without being awarded. It is composed of post-processing means 7 and the like.
[0023]
Further, the exhibition property determination means 3 calculates an auction price determination means 31 for determining an auction price from the property information BI and the evaluation information EI, and an expert member contract price for the exhibition candidate property in the exhibition candidate property database CDB. Expert member successful bid price calculation means 32. Further, the auction execution means 4 includes an evaluation fee calculating means 41 for calculating an evaluation fee at the time of successful bidding on the exhibited property data SD (i).
[0024]
FIG. 1 shows an operation example of the auction server AS. The auction management means 5 controls each stage of the auction in step S0. That is, the auction management means 5 displays an auction homepage (not shown) and accepts access of the general member client GC, the expert member client PC, the general member or the non-member client OC. Here, the member registers in advance, and reaches the access 1 to 3 through the authentication step on the home page with the id and password. Non-members can only participate in bidding, and register as a new member when bidding.
[0025]
In step S0, the auction management means 5 receives the accesses 1 to 3, starts the respective routines, arrives at a predetermined fixed time (for example, every one minute) at the predetermined time (for example, every one minute) by a timer interrupt, and executes the auction. It monitors when the bidding period of the property has come and starts each routine.
In step S0, when access 1 is received, that is, when an exhibition candidate article registration screen request is received from the general member client GC, the auction management unit 5 proceeds to step S11 and activates the exhibition candidate article registration unit 1. FIG. 4A shows an example of an exhibition candidate article registration screen transmitted by the exhibition candidate article registration means 1 in step S11. On this screen, the general member client GC inputs the property name of the exhibition candidate property, the lower-limit emotional price L and the reasonable emotional price U, which are the emotional prices described above, and further links to a detailed specification input screen (not shown). Enter the detailed specifications of the property, the appearance by digital camera, partial photos, comments, etc. according to the form, and click the send button.
[0026]
The information sent here is referred to as property information BI. In step S12, the candidate property registering means 1 acquires the property information BI, and in step S13, generates a new record in the property candidate database CDB. The property information BI is registered. FIG. 3 shows an example of the data structure of one record in the exhibition candidate property database CDB. The selling candidate article registration means 1 issues a unique selling candidate article id as a record key, and fills in the item indicated by the property information BI in this figure along with the registration date and time and the registrant id. Then, the exhibition / successful status flag F is set to 0, and the current date and time are entered in the flag update date and time item. The exhibition / successful status flag F is status information of the record, for example, 0: waiting for evaluation, 1: unsuccessful evaluation unsuccessful, 2: exhibiting, not successful bid, 3: exhibiting, not successful bid end, 4: exhibiting successful bid completed. It is decided. At this stage, the remaining items are not filled.
[0027]
Next, a description will be given of a case where, in step S0, an access 2 is received, that is, a request for an evaluation price registration screen for an exhibition candidate property is received from the expert member client PC. The auction management means 5 proceeds to step S21 and activates the evaluation price registration means 2. The evaluation price registration means 2 searches the exhibition candidate property database CDB, extracts a record with the exhibition / successful status flag F = 0, and generates an evaluation price registration screen as the evaluation target information HT based on this.
[0028]
FIG. 4B shows an example of the evaluation price registration screen thus generated. Here, the evaluation price in the present embodiment will be described with reference to FIG. In the present embodiment, the evaluation price is divided into two types, a reasonable evaluation price PS which is “a price at which it is estimated that selling at this price will be the market price” and a “price at which this price can be purchased.” And the purchase evaluation price PB. Then, based on the emotional price and the evaluation price described above, the algorithm shown in FIG. 6C is adopted as the auction price determination algorithm realized in this embodiment. That is, the exhibitor grasps the candidate property for listing within a range of the reasonable emotional price U from the lower emotional price L. On the other hand, the evaluation price of the expert member has a range from the purchase evaluation price PB to the reasonable evaluation price PS. The mutual relationship between these two cases can take the six cases shown in FIG. 6 (c). In the algorithm according to the present embodiment, in case 1 (the reasonable evaluation price PS <the lower-limit emotional price L), it is determined that the evaluation is not established and is not exhibited. In case 2 and case 3 (purchase evaluation price PB <lowest emotion price L), bid start price at bid down S1 = valid evaluation price PS, minimum price at bid down M = lowest emotion price L, bid start at bid up It is assumed that the price S2 = the lower-limit emotional price L and the price is exhibited. In Cases 4 and 5 (lowest emotion price L ≦ purchasing evaluation price PB and reasonable emotion price U ≦ valid evaluation price PS), the bid start price S1 at the time of auction, the reasonable evaluation price PS, the minimum price at the time of auction M = An exhibition is made with the purchase evaluation price PB and the bidding start price S2 at the time of auction being raised = purchase evaluation price PB. At the time of no successful bid, the evaluator is obliged to make a successful bid. In case 6 (lowest emotion price L ≦ purchasing evaluation price PB and valid evaluation price PS <reasonable emotion price U), the auction starting price S1 = the reasonable emotion price U, the lowest price M during the bidding M = the purchasing evaluation price PB, bidding start price at auction S2 = purchase evaluation price PB. At the time of no successful bid, the evaluator is obliged to make a successful bid. The above algorithm is made known to the expert member in advance at the time of membership registration of the expert member, and the member is enrolled with the consent of the expert member.
[0029]
Now, returning to step S21, based on the above assumptions, the screen shown in FIG. 4B is generated and transmitted in step S22, so that the expert member client PC can understand the meaning of the evaluation price on the screen. . Here, “Evaluation expiration date: h / m / d / h (x days / y hours until expiration date)” in the figure indicates that the evaluation price registration means 2 uses the given evaluation period value to update the flag update date and time of the property. Set by calculating from the current date and time. "Current highest evaluation price: reasonable evaluation price: PS (j) -k yen (evaluator: k), purchase evaluation price: PB (j) -z yen (evaluator: z)" is the evaluation price registration means 2 compares and sets a plurality of pieces of evaluation information EI stored in the evaluation information EI section of the property record. In the present embodiment, “ Only if the price you value exceeds the current maximum valuation above, please enter that amount below. ], The expert member client PC to be registered later for evaluation inputs the valid evaluation price PS and the purchase evaluation price PB according to the auction rules. In this embodiment, it is necessary to input at least the purchase evaluation price PB, but the valid evaluation price PS is optional. However, other embodiments may not impose these restrictions.
[0030]
For example, in another embodiment, each time one piece of evaluation information EI is received, the price is compared with the emotional price, and whether or not the property is available for sale is determined by a predetermined algorithm. It is also possible to end evaluation reception.
As described above, in step S22, only items with double circles in the property database CDB in FIG. 3 are transmitted as the evaluation target information HT, and the emotional price is kept secret. When the click of * is made on the screen of FIG. 4B, the screen shifts to a screen showing the evaluation information EI (* items of FIG. 3) which has already been taken into the exhibition candidate property database CDB so far.
[0031]
When the user inputs the valid evaluation price PS and the purchase evaluation price PB as the evaluation information EI from the expert member client PC on the screen shown in FIG. 4B and presses the send button, the evaluation price registration means 2 executes this evaluation information in step S23. The EI is received, and is registered in the exhibition candidate property database CDB in step S24. That is, when a plurality of pieces of evaluation information EI are already stored in FIG. 3, the main evaluation information EI is added to this.
[0032]
Next, a case will be described in which the access 3 is received in step S0, that is, a request to execute a bid for an exhibit is received from a general member or non-member client OC. The auction management unit 5 proceeds to step S31, and activates the auction execution unit 4. As described above, each property in the exhibition candidate property database CDB obtains an evaluation price during a predetermined period of time after registration, and accumulates evaluation information EI. Then, as will be described in detail later, when the evaluation time comes, these exhibit candidate properties are examined by the exhibit property determining means 3, and the property i determined to be exhibited is buffered as information of the exhibit property data SD (i). ing. As the exhibit property data SD (i), the item marked with a star in FIG. 3 is transcribed from the record of the exhibit candidate property database CDB. However, only items of the evaluation expert involved in the auction price determination are transcribed with (*).
[0033]
Thus, the auction execution means 4 generates auction data AD (i) from the information on the exhibited property data SD (i) and the bidding history nr (i) which is the bidding execution history in step S31. Is sent to the general member or non-member client OC of the access source. In the first access 3 to the property from the general member or the non-member client OC, the bid history nr (i) is naturally empty.
[0034]
FIG. 5 shows an example of the auction execution screen transmitted in step S32. FIG. 5A shows an example of a screen at the time of a bid down, and FIG. 5B shows an example of a screen at the time of a bid up. At the time of the bid down in FIG. 5 (a), the auction execution means 4 sets the bid down price S1 at the time of the bid down, the flag update date and time (auction start date and time), the current date and time, and the predetermined bid down mode conditions (in the case of this embodiment). The bid price ttt yen is calculated from the bid price of 1000 yen every 3 days, and the bid deadline is calculated at the time of m: d d h (the remaining x days and y hours until the deadline) and displayed on the screen. I do. In the auction time screen shown in FIG. 5B, the auction execution means 4 determines the bid expiration date: m d d h (expiration date) based on the flag update date and time (auction start date and time), the current date and the bidding period of the property. Until x days and y hours) are calculated and displayed on the screen. Also, the current highest bid amount: x yen (bidder: w) is acquired from the bid history nr (i) and displayed.
[0035]
Since the general member or non-member client OC makes a bid on the screen of FIG. 5, the auction execution means 4 receives the bid information n (i) in step S33, and stores it in the bid history nr (i) in step S34. to add. The bid information n (i) includes a bid amount, a bidder id, and a bid date and time.
Next, in step S0, an operation by a timer interrupt at a regular time (for example, every minute) will be described. The auction management means 5 has a predetermined evaluation period value and a bidding period value as initial setting values. For each timer interrupt, the current date and time and the exhibition / successful status flag F in each record of the exhibition candidate property database CDB, Check the update date and time.
[0036]
That is, the auction management means 5 identifies the property whose evaluation expiration date has expired from the flag update date and time and the current date and time of the record with the exhibition / successful status flag F = 0 (waiting for evaluation), specifies the candidate property for sale, and specifies the candidate property for sale. 3 executes steps S41 to S44. Further, the auction management means 5 identifies the property whose bid period has expired based on the flag update date and time and the current date and time of the record in which the exhibit / successful status flag F = 2 (unsold during exhibition), specifies the candidate property for execution, and executes the auction. Causes the means 4 to execute steps S51 to S54. The details will be described below separately for when the evaluation deadline has come and when the bid deadline has come.
[0037]
First, for all properties whose evaluation expiration date has passed, the exhibit property determining means 3 determines in step S41 whether or not to exhibit from the minimum emotional price LB and the purchase evaluation price PB of the exhibit candidate property. In the present embodiment, the algorithm described above with reference to FIG. 6 is used. In other words, if the property is case 1 (reasonable evaluation price PS <lower limit emotional price L) in FIG. 6, the evaluation is not established and it is determined that the article is not exhibited. Therefore, the exhibit property determining means 3 rewrites the exhibit / successful status flag F of the property from 0 to 1, and rewrites the flag update date and time to the current date and time. In addition, when the evaluation information EI is completely absent, etc., and the cases 1 to 6 cannot be determined, the evaluation is not established and it is determined that the exhibit is not exhibited, and the exhibit article determining means 3 performs the same processing.
[0038]
In other cases, the exhibiting property determining means 3 determines in step S41 that the property can be exhibited, and rewrites the exhibiting / successful status flag F of the record in the exhibiting candidate property database CDB to F = 2 (unsuccessful during exhibiting). Rewrite the flag update date and time to the current date and time. Then, the exhibit property determination means 3 activates the auction price determination means 31 in step S42.
[0039]
The auction price determination means 31 determines the auction price of these properties from the evaluation information EI in step S42. In this embodiment, the determination algorithm is performed according to FIG. 6 described above. As a result, the auction start bid price S1, the auction start price S2, and the auction minimum price M of each property are determined.
[0040]
Next, for the properties classified into cases 4 to 6 in the above step S42, the exhibited property determination means 3 activates the expert member successful bid price calculation means 32 and causes the expert member successful bid price to be calculated in step S43. This price is a price to have the expert member who has submitted the purchase evaluation price PB pick up the property when the property that could not be awarded by executing the auction is under the conditions of Cases 4 to 6. Although the value can be set variously, in this embodiment, the purchase evaluation price PB itself is used. The auction price and the expert member successful bid price determined as described above are written in the exhibition candidate property database CDB by the exhibition property determination means 3 in step S44. In this step S44, the auction price determination means 31 copies necessary items (items marked with a star in FIG. 3) in the exhibition candidate object database CDB of these objects to a buffer, and transfers them to the exhibition object data SD (i ). This is used for executing the auction, as described above in step S31.
[0041]
Lastly, a description will be given of the processing of the property for which it has been determined that the bid deadline has come in step S0. It should be noted that the determination of the bid deadline is slightly different between the time of the bid down and the time of the bid up. That is, at the time of the auction, the end of the predetermined bidding period is at the end of the bidding period, but at the time of the bidding down, it is determined that the bidding period has arrived at the end of the period in which the first bidding in the bidding mode has been performed.
[0042]
As described above in steps S31 to S34, in the situation where the exhibited property data SD (i) and the bid history nr (i) of the property i are accumulated, the property whose bid deadline has arrived in step S0 among these properties. Is specified by the auction management means 5, and the process proceeds to step S51. In step S51, the auction execution means 4 searches the bid history nr (i) of the property at the present time and determines a successful bid. If there is a successful bid, the auction execution means 4 proceeds to step S52, and writes the successful bid data, that is, the successful bid price and the successful bidder id, in the exhibition candidate property database CDB. In addition, the exhibition / successful status flag F in the exhibition candidate property database CDB is rewritten from 2 to 4, and the evaluation fee calculation means 41 is activated to calculate the evaluation fee from the determined bid amount.
[0043]
In this embodiment, the evaluation fee is determined in advance as a reward paid to the expert member who has submitted the purchase evaluation price PB related to the auction price in the case of successful bid. The value is determined at the time of member registration, for example, 10% of the determined bid price. In step S42, the evaluation fee calculation means 41 performs calculation in accordance with this rule, and in step S53, writes the result to the corresponding item in the exhibition candidate property database CDB, and stores the exhibition property data SD (i) of the property i from the buffer. delete. In step S53, the post-succeeding processing means 6 is activated to provide support for the payment of the successful bidder, but the details are outside the scope of the present invention, and will not be described here.
[0044]
If it is determined in step S51 that there is no successful bid, the auction executing means 4 shifts to step S54, and changes the exhibit / successful status flag F of the exhibit candidate property database CDB from 2 to 3 (exhibited and not completed). After rewriting, the processing means 7 is activated after the end of the non-successful bid. In either case, the flag update date is rewritten to the current date.
In the present embodiment, as described above, when the property corresponding to cases 4 to 6 in FIG. 6 is closed without a successful bid, the professional member who provided the evaluation information EI is obliged to make a successful bid on behalf of the property member. I have it. Then, in step S54, the post-unsuccessful-finish post-processing means 7 extracts, from the exhibition candidate property database CDB, a property in which the exhibition / successful status flag F is 3 and the expert member successful bid price item is not empty as a relevant property, and Identify house members and provide support such as successful bid procedures. Since the details are outside the scope of the present invention, they are omitted here.
