Accordingly, the seller can complete the transaction within the sales period by inputting only the sales conditions set in advance without unnecessary negotiations with the buyer, thereby greatly reducing transaction fatigue.

The natural language input by the seller and the buyer is analyzed to derive an answer suitable for the user's intention, and since the process of analyzing and interpreting the natural language input by the user is performed using a conventional natural language processing method, a detailed description thereof will be omitted. .

Hereinafter, each component of the used transaction automatic sales service providing system 1000 using a chatbot according to a preferred embodiment of the present invention will be described in detail.

Referring to FIGS. 1 to 6 , a used transaction automatic sales service providing system 1000 using a chatbot according to a preferred embodiment of the present invention includes a seller terminal 100, a buyer terminal 200, and a server 300, and It is configured to include the database 400.

The seller terminal 100 accesses the server 300 to register product information to be sold. Specifically, the seller terminal 100 enables the seller to register sales product information including the desired type of product for sale, a desired sales period, a pick-up schedule for the product for sale, and the weight of the product for sale.

In the process of registering a product for sale through the seller terminal 100, when the user inputs product information to be sold in conjunction with the product information of the database 400, the database 400 searches for product information identical to or similar to the entered product. and provide it to the user.

The database 400 is a database of information required to form a used price, and the price of a product is estimated based on this information.

The database 400 is a determinant factor in information on new products, information on used products, used market price information, past transaction information, lowest price of each product, actual transaction price of each product, popularity, brand ranking in category, and price change for each product. Product information including price change factor information giving Product information is updated at regular intervals.

Here, the information required to form the second-hand price may correspond to second-hand market price, past transaction information, actual transaction price of the product, popularity, and the like.

In addition, the seller terminal 100 may input shipping information including an address and product pick-up time. At this time, the seller terminal 100 has an automatic sales product registration function that automatically sells the product by the server 300 according to the set condition value when sales conditions including the sales period, minimum price of the product, and price fluctuation range are set. included

The purchaser terminal 200 accesses the server 300, checks the sales product registered by the seller terminal 100 through a chat window provided by the server 300, and proceeds with the purchase. In the process of making a purchase through the purchaser terminal 200, an interactive chatbot is operated in the chatting window so that questions requested by the purchaser can be answered.

The purchaser terminal 200 may request a price adjustment by inputting a phrase requesting a negotiable selling price when an amount for which price setting has been completed from the server 300 is output to the chatting window.

The server 300 automatically responds to questions required for transaction progress including product information, delivery reservation, and payment by operating an interactive chatbot in the chat window, and provides the sales period requested by the seller and the desired price of the product for sale. The sales price is set by reflecting factors that can affect the price of the product, including the sales conditions, the actual transaction price of the product, and the current demand for the product, and automatic sales are performed at the set price.

For example, the server 300 guides specification information about a product for sale through an interactive chatbot, guides price information when there is a price inquiry about a product for sale from a buyer, and responds to price negotiation when requesting price negotiation , Respond to inquiries about delivery reservations and payments, and guide procedures.

Specifically, the server 300 includes a product information providing module 310, a price estimation module 320, a price negotiation response module 330, and a transaction information de-identification processing module 340.

The product information providing module 310 interworks with the database 400 to search for and respond to product information received from the user from product information in the database 400 . In addition, if the information requested by the user is analyzed and determined to be information that is not searched for from product information, the search result is provided through the portal site.

For example, when the user inputs an inquiry about the weight information of a stroller of a specific brand, the weight information of the stroller of the corresponding brand is retrieved from the product information of the database 400 and the weight information is displayed in a chat window.

As another example, when the user inputs an inquiry about the color of a stroller of a specific brand, the color information of the stroller is searched from the product information in the database 400 and the color information is output to a chat window.

If the user enters an inquiry about whether there is a risk of discoloration after using the product for a long time, and the above inquiry is information that cannot be searched from the product information, it is determined that it cannot be derived from the product information and the portal site is linked. Provides the search results of the portal site.

The price estimating module 310 estimates the second-hand price of a product in consideration of factors including the user's search frequency, residential area, new product price, second-hand market price, and competitive product.

Specifically, the price estimation module 310, when information on a product to be sold is input from the seller terminal 100, searches for and extracts a product identical to or similar to the input sales value from the product information in the database 400, extracts, and trades used products. Estimate the expected selling price of a product using a price estimation model.

Here, the used transaction price estimation model is an artificial intelligence-based algorithm that estimates and presents the used transaction price by reflecting various factors that can affect the used transaction price of a product. It is an algorithm that estimates the expected selling price of a product to be sold by considering one or more of the conditions including the market price of the brand, the user's search frequency, the region of residence, the user's product inquiry frequency, and the user's product inquiry frequency.

For example, the price estimating module 310 may determine the search volume by region of products searched in real time on the portal site, and estimate that there are many buyers or sellers if the product search volume is high in the corresponding region.

When the price negotiation response module 320 detects a phrase requesting price adjustment from the buyer, the interactive chatbot operates and proceeds with price negotiation in response to the buyer's request.

The price negotiation response module 320 checks whether the product is negotiable in price, and if it is determined that the price is negotiable, it adjusts the selling price of the product using an artificial intelligence-based second-hand price adjustment algorithm to determine the first proposed sales price. The value adjusted from the price is presented in the chat window.

At this time, the used price adjustment algorithm is an algorithm that automatically adjusts the selling price by reflecting factors that can give volatility to the selling price of the product.

Here, the factors that can give volatility to the selling price of the product are the current demand for the product, the number of times users search for the product, the number of chat rooms opened in which transactions are being conducted related to the product, the exposure time of the product, and the initial registration time of the product. , the number of registrations of the same product, and the sales period.

For example, the price negotiation response module 320 checks the price at which the product is being traded in real time and adjusts the price by automatically lowering the price when the desired selling price registered by the seller is higher than the traded price.

In the chat window, the average second-hand market price, selling price, and negotiating price are displayed in a visualized form such as figures and graphs so that buyers can intuitively check them.

The price negotiation response module 320 updates and outputs the re-adjusted sales price of the product through a plurality of times until the target sales period. For example, the sales price of a product may be updated at regular intervals such as 1 hour, 6 hours, 12 hours, and 24 hours.

For example, it can be estimated that there is a high demand for the corresponding product when the number of chat room openings is high by checking the number of chat room openings in which transactions are being conducted in relation to a specific product.

In the case of products whose price is adjusted by the used price adjustment algorithm, where there is a change in the rate of price decrease, or a product that meets the conditions including the sales period, the position where the product can be checked is changed and exposed on the user terminal whenever there is a change. let it be

After the price is negotiated with the buyer through the above process, payment and delivery procedures for the purchase of the product are carried out.

The transaction information de-identification processing module 330 is a module that de-identifies personal information from the transaction information input from the seller or buyer's terminal and provides it to the counterparty, and encrypts the personal information required for the transaction. Through processing, the leakage of personal information is prevented and personal information is protected by selectively exposing only necessary information without exposing it to the counterparty.

More specifically, the transaction information de-identification processing module 330 collects personal information input from the seller or buyer terminal 200 as a transaction party, pseudonymizes it, stores it in the database 400, and Personal information including phone number, address, and account number exposed to the counterparty is extracted, part of the personal information is de-identified, and then the de-identified transaction information is provided to the counterparty terminal.

For example, among transaction information, information that is de-identified is personal information including name, phone number, shipping address, and account number, and information that is not de-identified is price, date and time of shipment, product price, product type, product amount, Volume and weight, transaction method included.

Accordingly, among the information input from the seller terminal, information related to personal information including the seller's name, phone number, forwarding address, and account number is partially de-identified and output in an unexposed state to the buyer's terminal.
