In addition, as used herein, the term "second user interface" refers to a user interface provided to enable a seller to sell a product corresponding to product information included in a quotation registered on a predetermined quotation board in a reverse auction manner. do.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a flowchart illustrating a method of providing an estimating service in an estimating service server according to an embodiment of the present invention.

In step 101, the quotation service server classifies product information regarding a predetermined product by category and stores the product information in a product database. Hereinafter, the product database will be described in detail with reference to FIG. 2.

Referring to FIG. 2, the merchandise database 200 stores merchandise information by grouping merchandise according to categories such as "image home appliance", "household home appliance", and "computer." In addition, each category may have subcategories that classify products in more detail. For example, subcategories such as "air conditioner", "refrigerator", "washing machine", etc. exist in the category "home appliances". In addition, each sub category again includes product information on the sub category or the individual product. In addition, although not shown in Figure 2, the product database 200 may further include an association between the product information. For example, product information belonging to a category such as "PC peripheral device >> PC part", "image home appliance >> digital camera", etc. further includes information about the association relationship which shows mutually compatible products.

In step 102, the quotation service server provides a first user interface for selecting the product information stored in the product database 200 in a predetermined quotation web site. In this case, the first user interface may be for selecting product information by a category search method using a product database as shown in FIG. 2.

In step 103, the first user selects predetermined product information through the first user interface. That is, the first user may select the category "Household Appliances >> Air Conditioning" as a category, and then select product information on a specific product of the corresponding category.

In step 104, the quotation service server includes the product information about the product selected by the first user in the quotation sheet of the first user and prepares the quotation.

Hereinafter, steps 103 and 104 will be described in more detail with reference to FIGS. 3 and 4.

3 is a diagram illustrating an example of a first user interface provided by the quote service server when the first user selects the category "PC peripheral device >> PC component". As indicated by reference numeral 301, FIG. 3 illustrates a case in which the first user selects a sub-category of "Intel CPU" again.

When "Intel CPU" is selected, the quotation service server displays the product information belonging to the "Intel CPU" category as shown in FIG. 4 so that the first user can select the desired product information. For example, the corresponding product information may be selected by clicking the "add" menu displayed for each product information. 4 illustrates a case in which the first user selects a product named "Intel Pentium 4 530", and accordingly, the quotation service server includes the selected product information in a predetermined quotation. The quotation has not been completed yet, and may be completed when a predetermined quotation completion command is input from the first user.

If the quotation creation is not completed, in step 105, the quotation service server searches for the product information associated with the product information selected by the first user by referring to the association relationship included in the product database 200. For example, when the first user selects "Intel Pentium 4 530", which is product information belonging to the category "PC Peripherals >> PC Parts >> Intel CPU", the product information is searched for products compatible with the CPU. do.

As another example, when the first user selects the "Pentax * ist DS camera" which is the product information belonging to the category "Image consumer electronics >> Digital camera", the "Pentax FA 43mm F1.9Limited" lens which is available for the selected camera "You can search for a lens.

In step 106, the quotation service server generates a product list including the retrieved product information and provides it to the first user. The first user may select another product information from the provided product list and additionally include it in the quotation. On the other hand, if there is no product information associated with the previously selected product information, the quote service server, the first user interface for selecting the highest category again, or products belonging to the same category as the previously selected product information It is also possible to provide a first user interface for selecting information.

The estimating service server repeatedly performs steps 103 to 106 to complete the quotation of the first user. Steps 103 to 106 may be performed until the first user includes all of the desired product information in the quotation, until a command for completing the quotation is input.

Further, according to another embodiment of the present invention, when the quote relates to a computer component and the first user accesses the quote service server using his PC, the first user selects from the PC. Receive information on the current computer part corresponding to the computer part, that is, specification information. The quotation service server may receive the specification information, compare the specification information with the product information included in the quotation, by item, and provide the comparison information to the first user. For example, when the product information included in the quotation is "Intel Pentium 4 530" and the specification information for the CPU being used for the PC of the first user is "Intel Pentium III", the quotation service server may be configured as a server. Comparing information such as processing speed and cache memory may be generated for the CPU and provided to the user. Thus, it is possible to automatically compare the PC part that the first user is currently purchasing with his PC specification.

In step 108, the quotation service server registers the created quotation of the first user in the quotation board. The quotation service server may obtain the consent of the first user, or automatically register the quotation on the quotation board after the quotation is completed.

In step 109, the second user can access the quote service server, select and download the quote of the first user registered in the quote board. In other words, the second user may write a quote directly, but if a quote including product information on the product desired by the second user is already generated and registered in the quote board, the quote registered in the quote board is downloaded. Can be used.

In step 110, the quote service server transmits the selected quote to the terminal of the second user in response to the download request of the second user.

In addition, the second user may use the quotation in a manner of reading the quotation displayed on the quotation board even though the quotation is not downloaded.

5 is a flowchart illustrating a method of compensating a quote registrant according to the number of downloads of a quote written on a quote board according to the present invention.

In step 501, the quote service server stores a quote database including a download count or a recommendation count for each quote registrant. The quote registrant is the same as the first user who creates a quote and registers it on the quote board. 6 is a diagram illustrating an example of data included in the quotation database. The quote database 600 may include a registrant identifier for identifying a first user who has generated a quote and registered on the quote board, a quote identifier for identifying the quote, a number of downloads of the quote by a second user, and a quote for the third user. Stores the recommended number of recommendations.

In step 502, the quotation service server counts the number of downloads of the quotations registered in the quotation board.

That is, as described above, when the quotation that is created and registered by the first user is transmitted to the user terminal of the second user, the quotation service providing server may download the number of downloads associated with the first user from the quotation database 600. It is possible to count the number of downloads for each quote registrant by reading and by increasing the read count by one. In this case, only the logged-in user can download the quotation, and even if the same user repeatedly downloads the same quotation, the download count may be updated only for the first download and the download count may not be counted for subsequent downloads. have.

In step 503, the quote service server displays the updated number of downloads for the quote of the first user on the quote board.

Also at step 504, the quote service server records the updated download count in association with the first user in the quote database. Referring to the reference numeral 602 of FIG. 6, when the second user downloads the quotation of "Kim Hyo-jin" who is a quote registrant, the number of downloads associated with Kim Hyo-jin is increased by 1, that is, updated from 35 times to 36 times. After that, the quotation is displayed on the bulletin board and updated to 36 in the quotation database.

In step 506, the quote service server may determine the compensation content for the quote registrant based on the number of downloads. For example, the quote service server may provide mileage proportional to the number of downloads.

7 is a flowchart illustrating a method of compensating a quote registrant according to a recommendation number for a quote written on a quote board according to the present invention.

In step 701, as shown in FIG. 6, the quote service server stores a quote database including a recommendation number for each quote registrant.

In step 702, the third user reads the quotations registered in the quotation board, and then inputs the recommendation information for the quotation that is determined to be well written.

In step 703, the quote service server increases the number of recommendations associated with the quote by one. Referring to 602 of FIG. 6, when the third user recommends the quotation of the quote registrant “Hyojin Kim”, the existing recommendation number is updated 12 times to 13 times.

In step 704, the quote service server displays the number of recommendations for each quote registered in the quote board. Therefore, when the recommendation number associated with the quote of "Kim Hyo Jin" is updated to 13 times, the updated recommendation number is displayed.

In operation 705, the quotation service server may determine a reward for the quote registrant based on the recommendation number. For example, the quote registrant may be provided mileage in proportion to the recommendation number.

In addition, the quotation service server may determine the compensation contents for the quote registrant in consideration of both the number of downloads and the number of recommendations.

In addition, according to another embodiment of the present invention, the quotation service server may allow only the logged-in user to recommend the quotation, so that the same user may limit the recommendation for one quotation only once.

Hereinafter, referring to FIG. 8, a process of enabling a quote registrant to purchase goods on a quote in a reverse auction manner using a quote registered in the quote board will be described. Each step shown in FIG. 8 may be performed after steps 101 to 108 are performed.

In step 801, the quote service server provides a second user interface to the users. The second user interface is for inputting a selling price of a product corresponding to the product information included in the quotation registered in the quotation board, and allowing a reverse auction scheme to bid on the selling of the product. In other words, the sellers may bid on the sale of the corresponding goods by inputting the selling conditions such as the selling price, the specification, the number of the goods to be sold through the second user interface (step 802).

In step 803, the quotation service server generates a sales price list including the sales price input from the seller, and provides it to the first user. The selling price list may be provided in an ascending or descending order of the selling price. In addition, the quote service server may register the generated sale price list in the quote board, so that the first user or other users can browse. Therefore, the first user can recognize at a glance the sales conditions such as the selling price for the products he / she wants to purchase without searching for and searching for the products to be purchased. In addition, the seller obtains a new place for selling a quote board.

In step 804, the first user selects a seller who has provided an appropriate sale condition for a desired product for the sale price list. Accordingly, the first user may select a seller who satisfies his purchase desire among various selling conditions. In other words, for the product "air conditioner" in the quotation, the first seller is free to install at the sale price of 1 million won, the second seller is suggested to install it at the sale price of 950,000 won to 30,000 won, and the third seller is installed to the sale price of 950,000 won. If the sale conditions such as 50,000 won, free gifts, etc. are presented, the first user can select the desired sale conditions to purchase the air conditioner.

In step 805, the quotation service server determines a seller who has entered a sale price selected from the first user as a sale successful bidder. The seller determined as the sales successful bidder may sell the goods by contacting the first user, and the quotation service server may relay a sale between the sales successful bidder and the first user in conjunction with a predetermined shopping server or a billing server. You can also control it.
