Description

  The present invention relates to a normal auction / reverse auction cooperation system using the Internet or the like.

  In recent years, an auction system using the Internet (see, for example, Patent Documents 1 and 2) is provided by a plurality of companies, and its use is increasing. In a normal auction system, an exhibitor sells a product, and multiple bidders bid for a desired amount for the product, and the bidder who bids the highest price within a predetermined period Make a successful bid.

On the other hand, unlike the normal auction system described above, the buyer (requester) posts a request for a product that the buyer (requester) wants, and the seller (applicant) who viewed it issues an offer (application) for the product offer. There is also a buyer-driven reverse auction (request auction) system in which a transaction is established when the above conditions are met.

  As mentioned above, there are conventional auction systems and reverse auction systems that have been operated by the same operator, but they are independent systems, and the cooperation between systems is completely considered. Was not.

  By the way, when a product exhibited in a normal auction system is not successful, a reverse auction system is browsed to see if there is a request for a similar product. However, at that time, the contents (text of product description, product image, etc.) entered at the time of listing in a normal auction system must be entered again as the contents of application in the reverse auction system, and the input operation is complicated. There was a problem that there was. A similar problem can occur if a reverse auction system applies for a request but is not closed.

  In addition, when a product exhibited in a normal auction system is not sold, the reverse auction system is not always transferred. In that case, there is a problem that effective use as an auction system is not sufficiently performed. A similar problem can occur if the reverse auction system does not close the request.

  The present invention has been proposed in view of the above-described conventional problems, and the object of the present invention is to perform a duplicate input operation by taking close cooperation between a normal auction system and a reverse auction system. It is an object of the present invention to provide a normal auction / reverse auction linkage system that can be reduced and can activate the use of both systems.

In order to solve the above-described problems, in the present invention, as described in claim 1, the seller side posts an exhibition about a product desired to be sold, and the buyer side who has viewed the bid places a bid, The seller-driven regular auction system where the transaction is established when the conditions are met and the request for the product that the buyer wants are posted, and the seller who viewed this submits an application for product provision, and both conditions match And a buyer-initiated reverse auction system in which the transaction is completed in the case where an offer to the normal auction system was not closed, the normal auction system was not closed to the reverse auction system. through the network the data to request information of a similar request with the listing information according to the exhibition Means for transmitting Te, the reverse in the auction system side, acquires data information of a similar request made similarity retrieval from the request information based on the selling information according to the listings that were not traded, the network to the normal auction system Means for transmitting via the network, and means for transmitting the data of the information of the similar request acquired from the reverse auction system to the client terminal used by the seller side of the normal auction system on the normal auction system side via the network The normal auction system side receives, via the network, data for requesting the output of exhibition information including text information and image information inputted at the time of listing for the regular auction system from the client terminal. And means for transmitting the exhibition information data held in the internal storage area of the normal auction system from the normal auction system to the client terminal via the network, and correcting from the client terminal on the reverse auction system side The gist of the normal auction / reverse auction cooperation system is provided with means for receiving, via a network, data for a request for posting based on the above-described exhibition information .
In addition, as described in claim 2, a seller-initiated type in which a seller posts an article about a product he / she wants to sell, a buyer who has viewed the bid places a bid, and a transaction is established when both conditions are met. And a buyer-driven reverse auction system in which a request for a product that a buyer desires is posted, a seller who views the request submits an application for product provision, and a transaction is established if both conditions are met If the request to the reverse auction system is not closed, information on similar listings with request information related to the request that has not been closed from the reverse auction system to the normal auction system is provided. Means for transmitting the requested data over the network; Usually, the auction system side performs a similar search from the exhibition information based on the request information concerning the request that has not been closed, obtains the data of similar exhibition information, and transmits the data to the reverse auction system via the network; A means for transmitting information on similar listings acquired from the normal auction system to a client terminal used by the buyer of the reverse auction system on the reverse auction system side, and on the reverse auction system side, Means for receiving instruction request data for outputting request information including text information and image information inputted at the time of posting a request to the reverse auction system from a client terminal via the network; Means for transmitting the request information data held in the internal storage area of the reverse auction system from the source auction system to the client terminal via the network, and the normal auction system side performs correction from the client terminal. The system can be configured as a normal auction / reverse auction cooperation system including means for receiving data on an exhibition posting request based on the received request information via a network.

Further, as described in claim 3 , the normal auction / reverse auction linkage system according to any one of claims 1 and 2 , wherein the similar request or exhibition information is a request or exhibition information. Statistical information such as the number of cases and average price can be included.

  In the normal auction / reverse auction linkage system of the present invention, the close input between the normal auction system and the reverse auction system can reduce duplicate input operations and activate the use of both systems. Can be achieved.

<Processing Example 1>
FIG. 3 is a diagram illustrating a processing example for the seller when the normal auction is not established. In FIG. 3, when the normal auction system 11 is not established (when the system side determines that there is no bid that satisfies the condition by the end date and time, the seller selects the end because there is no bid that satisfies the condition. The normal auction system 11 requests the reverse auction system 12 to search for similar request information from the exhibition information (step S1).

  In response to this, the reverse auction system 12 searches for similar request information by the search server 109, and usually obtains the number of similar requests and statistical information (average price, minimum price, maximum price, contract rate, etc. of requests / applications / contracts). It responds to the auction system 11 (step S2).

  Then, the normal auction system 11 provides the number of similar requests and the statistical information to the seller (seller) client 3A together with the normal auction end notification (step S3).

  The exhibitor who is interested in shifting to the reverse auction by looking at the number of similar requests and the statistical information instructs the reverse auction system 12 to output the detailed information of the similar requests from the client 3A (step S4). The reverse auction system 12 that has received the detailed information of the similar request outputs to the client 3A (step S5). It should be noted that the output instruction of the similar request information can be easily performed from a URL or the like embedded therein by clicking a predetermined portion of the page provided from the normal auction system 11. In addition, the output of similar request information can be performed in two stages, such that a list of similar requests is first output and detailed information is output for each request that is of interest.

  Next, the exhibitor who has decided to apply for the reverse auction by looking at the detailed information of the similar request instructs the normal auction system 11 to output the exhibition information (text information input at the time of exhibition, image information, etc.) from the client 3A. In response to this, the normal auction system 11 outputs the exhibition information to the client 3A (step S7).

  The seller then modifies the acquired listing information as necessary (the listing is a one-way advertisement for the item, but the application is an appeal in response to the request), and then reverses from the client 3A. An application is made to the auction system 12 (step S8).

  As described above, when the normal auction is not established, the exhibitor can be actively guided to the reverse auction, and the entry information at the time of the exhibition can be reused so that the input operation becomes easy. .

<Processing example 2>
FIG. 4 is a diagram illustrating an example of processing for a bidder when a normal auction is not established. In FIG. 4, when the normal auction system 11 is not established, the normal auction system 11 makes a search request for similar request information from the exhibition information to the reverse auction system 12 (step S11).

  In response, the reverse auction system 12 searches for similar request information by the search server 109, and returns the number of similar requests and statistical information to the normal auction system 11 (step S12).

  Then, the normal auction system 11 provides the number of similar requests and statistical information to the bidder (buyer) client 3B together with the normal auction end notification (step S13).

  A bidder who is interested in shifting to the reverse auction by looking at the number of similar requests and the statistical information instructs the reverse auction system 12 to output detailed information of the similar requests from the client 3B (step S14). The reverse auction system 12 that has received the detailed information of the similar request outputs to the client 3B (step S15). It should be noted that the output instruction of the similar request information can be easily performed from a URL or the like embedded therein by clicking a predetermined portion of the page provided from the normal auction system 11. In addition, the output of similar request information can be performed in two stages, such that a list of similar requests is first output and detailed information is output for each request that is of interest.

  Next, the bidder who has determined the request for the reverse auction by seeing the detailed information of the similar request makes a request to the reverse auction system 12 from the client 3B (step S16).

  Thus, when the normal auction is not established, the bidder can be actively guided to the reverse auction.

<Processing example 3>
FIG. 5 is a diagram showing a processing example for the requester when the reverse auction is not established. In FIG. 5, when the reverse auction system 12 does not find an application that satisfies the conditions for its own request, the requester (buyer side) notifies the reverse auction system 12 of no corresponding from the client 3C (step S21). (This step may be omitted if the system determines that there is no application that satisfies the conditions by the end date and time.)

  Next, the reverse auction system 12 makes a search request for similar exhibition information from the request information to the normal auction system 11 (step S22).

  In response to this, the normal auction system 11 searches for similar exhibition information by the search server 109 and reverses the number of similar exhibitions and statistical information (the average price of exhibition / bid / contract, minimum price, maximum price, contract rate, etc.). It responds to the auction system 12 (step S23).

  Then, the reverse auction system 12 provides the number of similar listings and statistical information to the client 3C (step S24).

  The requester who is interested in shifting to the normal auction by looking at the number of similar items and the statistical information instructs the client 3C to output the detailed information of the similar items to the normal auction system 11 (step S25). The normal auction system 11 that has received the information outputs detailed information on similar listings to the client 3C (step S26). It should be noted that an instruction to output similar exhibition information can be easily made by clicking a predetermined location on a page provided from the reverse auction system 12 from a URL embedded therein. Also, the similar exhibition information output instruction can be performed in two stages, such as first outputting a list of similar exhibitions and outputting detailed information for the listings of interest.

  Next, the requester who has decided to bid for the normal auction by looking at the detailed information of the similar listing, places a bid from the client 3C to the normal auction system 11 (step S27).

  Thus, when the reverse auction is not established, the requester can be actively guided to the normal auction.

<Processing example 4>
FIG. 6 is a diagram illustrating an example of processing for an applicant when a reverse auction is not established. In FIG. 6, when the reverse auction system 12 is not established (when the system side determines that there is no application satisfying the condition by the end date and time, the requester selects the termination because there is no application satisfying the condition. The reverse auction system 12 requests the normal auction system 11 to search for similar exhibition information from the request information (step S31).

  In response to this, the normal auction system 11 searches the similar auction information by the search server 109, and returns the number of similar auction items and statistical information to the reverse auction system 12 (step S32).

  Then, the reverse auction system 12 provides the number of similar exhibitions and statistical information to the client 3D of the applicant (seller side) (step S33).

  The applicant who is interested in the transition to the normal auction by looking at the number of similar items and the statistical information instructs the client 3D to output the detailed information of the similar items to the normal auction system 11 (step S34). The normal auction system 11 that has received the information outputs detailed information on similar listings to the client 3D (step S35). It should be noted that an instruction to output similar exhibition information can be easily made by clicking a predetermined location on a page provided from the reverse auction system 12 from a URL embedded therein. Also, the similar exhibition information output instruction can be performed in two stages, such as first outputting a list of similar exhibitions and outputting detailed information for the listings of interest.

  Next, the applicant who has decided to participate in the normal auction by looking at the detailed information of the similar exhibition instructs the reverse auction system 12 to output the application information (text information, image information, etc. inputted at the time of application) from the client 3D. In response to this, the reverse auction system 12 outputs the application information to the client 3D (step S37).

  The applicant modifies the acquired application information as necessary (the application is appealing according to the request, but the exhibition is a unilateral advertising content for the exhibited product), and the client 3D normally An auction system 11 is displayed (step S38).

  In this way, if the reverse auction is not successful, the applicant can be actively guided to the normal auction, and the entry information at the time of application can be reused to make an entry, which facilitates the input operation. .
