1 is a conceptual diagram of an item replacement matching platform service providing device 100 through item value evaluation according to an embodiment of the present invention.

Referring to FIG. 1 , an item replacement matching platform service providing apparatus 100 through item value evaluation according to an embodiment of the present invention provides a recommended item to a user, and mutually exchanges information based on the value of the item owned by the user. It is possible to provide a rewriting service to . Meanwhile, the device 100 for providing an item rewriting matching platform service through item valuation may be referred to as an 'electronic device 100' in the present invention.

At this time, the user terminal 200 is a desktop computer (desktop computer), laptop computer (laptop computer), notebook (notebook), smart phone (smart phone), tablet PC (tablet PC), mobile phone (mobile phone) capable of communication , smart watch, smart glass, e-book reader, PMP (portable multimedia player), portable game device, navigation device, digital camera, DMB (digital multimedia broadcasting) player , a digital audio recorder, a digital audio player, a digital video recorder, a digital video player, a personal digital assistant (PDA), and the like.

2 is a block diagram of an electronic device 100 according to an embodiment of the present invention.

An electronic device 100 according to an embodiment includes a processor 110 and a memory 120 . The processor 110 may perform at least one method described above. The memory 120 may store information related to the above method or store a program in which the above method is implemented. Memory 120 may be volatile memory or non-volatile memory. The memory 120 may be referred to as a 'database', a 'storage unit', or the like.

The processor 110 may execute a program and control the electronic device 100 . Program codes executed by the processor 110 may be stored in the memory 120 . The device 100 may be connected to an external device (eg, a personal computer or network) through an input/output device (not shown) and exchange data.

At this time, the processor 110 may select a first recommendation item based on the user's purchase history. In this case, the item may be a product sold on a platform to which the paraphrase according to the present invention is applied, and may be, for example, a product such as jewelry. A method of selecting the first recommendation item will be described later with reference to FIG. 3 .

In addition, the processor 110 may provide information about the first recommendation item to the user terminal 200 of the user. This is to help the user make a selection by preferentially providing products that the user may be interested in.

In addition, the processor 110 may obtain information about a first selection item selected by the user for rewriting among the first recommendation item and all items from the user terminal 200 .

At this time, the user may select from the first recommended items, but may not like the recommended items, so the first selection items including all items may be selected.

Also, the processor 110 may generate a first value for one or more first owned items of the user. In case of applying for rewriting according to an embodiment of the present invention, it is preferable to consider mutual values because users who abuse them may appear if mutual values are not considered.

In this regard, a method of calculating the first value of the first owned item of the user will be described later with reference to FIG. 4 .

In addition, the processor 110 may extract a second owned item having a first value matching the second value of the first selection item, and provide the second owned item to the user terminal 200. have. Since the first owned item owned by the user may not match the value of the first selected item, filtering is primarily performed.

In addition, when the processor 110 obtains information about a second selection item that the user selects for rewriting among the second owned items from the user terminal 200, the first selection item and the second selection item. Rewrite information of the selected item can be created.

At this time, the processor 110 transfers the rewriting information to the user and the operator of the platform to which the rewriting is applied, so that the user guides the second selection item to be sent and the operator guides the first selection item to be sent. can do.

3 is a diagram illustrating a process of selecting a first recommendation item according to an embodiment of the present invention.

Referring to FIG. 3 , the processor 110, based on the purchase details of the user, when the number of items purchased by the user exceeds a preset first threshold number of purchases, The first recommendation item may be selected.

This is to first check whether there are enough purchase details to be used by the user as basic data, since basic data is required to select a recommended item.

At this time, the first threshold number of purchases may be arbitrarily set by an operator as the number of times that can be utilized as the basic data, or may be set based on the average number of purchases of all buyers (users).

In more detail, when the number of items purchased by the first user exceeds the first threshold number of purchases, the processor 110 classifies the items purchased by the first user by type, material, and brand; The first type, the first material, and the first brand most purchased by the first user are extracted, and items corresponding to all of the first type, the first material, and the first brand are set as the first recommendation item. You can choose.

Since the user is highly likely to select the same item as the type, material, and brand of the purchased item, the present invention selects the same item as the type, material, and brand as the first recommendation item.

In addition, when the number of items purchased by the user is less than or equal to the first threshold number of purchases, the processor 110 makes the first recommendation based on purchase details of other users who have purchased the same item as the item purchased by the user. Items can be selected.

This is because if the number of purchases to select the recommended item is not sufficient, the accuracy of the recommended item may be lowered, so that the user can make a practical recommendation using the purchase details of other users who have purchased the same item, and This is to supplement the basic data.

In more detail, when the number of items purchased by the first user is less than or equal to the first threshold number of purchases, the processor 110 determines the same number of items purchased by the first user based on purchase details of all customers. Second users who purchased the item may be extracted as the first group.

In addition, the processor 110 determines the number of purchases of items among the second users based on the purchase details of the second users included in the first group exceeding a predetermined second threshold number of purchases. Users may be extracted as a second group.

This is to extract other users having the same taste as the user into the first group, but to remove users who do not have a sufficient number of purchases as noise. Through this, it is possible to extract users having the same taste as the user and having a sufficient number of purchases to select a recommended item.

In this case, the second threshold number of purchases may be set equal to the first threshold number of purchases or may be set to the average number of purchases of second users included in the first group.

In addition, the processor 110 classifies items purchased by the third users by type, material, and brand based on purchase details of the third users included in the second group, and the third users The most purchased second type, second material, and second brand may be extracted, and an item corresponding to all of the second type, second material, and second brand may be selected as the first recommendation item.

4 is a diagram illustrating a description of a rewriting procedure according to an embodiment of the present invention.

Referring to FIG. 4 , the user can apply for replacement by selecting a first selection item that the user wants to replace, and selecting a second selection item to be used for replacement among items owned by the user.

At this time, as described above, the first selection item and the second selection item to be used for replacement should have the same value or be included in a similar range to prevent abuse.

At this time, the value of the first selection item may be set in advance as a selling price, but the value of the second selection item may be regarded as a used product used by the user to set the selling price of the same product, so the value is evaluated accordingly. should be done again.

To this end, the processor 110 generates the first value for the first owned item, the usage period calculated based on the purchase time and current time of the first owned item, the purchase price, and the first owned item. The first value may be generated based on the total number of purchases of items purchased in the past derived based on the number of times of rewriting associated with owned items and purchase details of the user.

Looking in more detail, the first value may be calculated by Equation 1 below.

[Equation 1]

At this time, Value_1 means the first value, NoBI (Number of Buying Items) means the total number of purchases, NoCE (Number of Consecutive Exchanges) means the number of rewrites, and PoU (Period of Using ) may mean the period of use, and Price may mean the purchase price.

Through this, the longer the period of using the first owned item, the lower the value, and even if it is rewritten several times in connection with the first owned item, the value is set low, so that the number of times of rewriting is slightly suppressed. If the total number of purchases made by the user is large, since the user can be regarded as a regular customer or VIP, the value of the first owned item decreases slowly as the total number of purchases increases, thereby obtaining an effect of securing loyal customers. can

5 is a diagram illustrating a process of extracting a second item based on a value according to an embodiment of the present invention.

Referring to FIG. 5 , the processor 110 extracts a second owned item having a first value matching the second value of the first selection item, but within a predetermined error range with the second value. If there is a first owned item having a first value that is equal to, the first owned item may be extracted as the second owned item.

This may mean a case where mutual exchange is possible because the value is the same or similar.

At this time, the error range may be arbitrarily set by the operator of the platform, and may be set to, for example, 10%, 5%, and the like.

In addition, the processor 110, when there is no first owned item having a first value included in the error range and the second value, the item having the smallest difference between the second value and the first value Extracted as the second owned item, but generating additional amount information corresponding to the difference between the second value and the first value, and providing the second owned item and the additional amount to the user terminal 200 together. can do.

This is to enable exchange while adding the difference between items in case there is no owned item that can be exchanged for the same grade.
