Description

System and method for agent information using computer communication network using computer communication network

The present invention relates to an information brokerage system and a method using a computer communication network, and in particular, to set different criteria for valuation of information for sale by seller through behavioral analysis and propensity analysis on the computer communication network of each seller to sell information. The present invention relates to an information intermediation system using a computer communication network and a method for applying different intermediary unit prices to sellers based on the valuation criteria.

As the use of computer networks, including the Internet, has become more common, companies, organizations, or individuals who have previously used corporate or event promotions to unspecified people by using the public or the media, etc., advertise one-on-one using these networks. Is on the rise. That is, companies, organizations, or individuals who need corporate advertisements or event promotions perform one-on-one advertisements by sending an e-mail containing the contents of the corporate advertisements or event promotions to the general public. They must have personal information, including their email address.

The information brokerage system refers to companies, organizations or individuals (hereinafter referred to as "buyers") who need personal information, including their e-mail addresses, and their own information (e.g., name, age, hobbies, contacts, etc.). It refers to a system that connects people who want to open and receive a certain price (hereinafter referred to as 'seller').

This information brokerage system allows various sites operating on the Internet to select members who have subscribed as members of the site to select whether or not to disclose the information and the limit of the information disclosure, and then pay a predetermined price to secure the information of the members. It is usually operated by selling the information to external buyers who have paid. At this time, the member who has approved to disclose his or her information is provided with a predetermined price. Generally, a useful point score or discount coupon is provided within the site.

In this case, the member who has approved the disclosure of his or her information becomes a 'seller'. In the conventional case, when the seller sells the seller's information or pays the seller for the information, the characteristics of the information are displayed. Did not consider at all. In other words, when selling information to buyers, a uniform price is applied to all information regardless of the content or quality of the information.

Therefore, even if the buyer wants high-value information, such a uniform pricing method has a disadvantage in that it is indistinguishable from relatively low-value information.

For example, when the buyer is a 'car company', it is useful to have a lot of information of people who can buy a car because the car company has the biggest purpose of promoting and selling a subsidiary car. Therefore, from the point of view of a buyer who is an automobile company, information of people who can buy a car is relatively high, and information of people who are not car is relatively low. However, conventionally, since the price of information was determined in a uniform manner without considering the value of each information, neither the seller nor the buyer could trade information at a reasonable price.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to sell information to sellers by seller through behavioral analysis and propensity analysis of each seller who wants to sell the information. The present invention provides an information brokerage system and method for setting different valuation criteria for different valuation criteria and applying different intermediary unit prices for each seller based on the valuation criteria.

The values shown in these evaluation index tables are merely examples for explaining the present invention in more detail, and each evaluation index can be set differently according to circumstances.

10 is a flowchart illustrating a method for mediating information according to an embodiment of the present invention. Referring to FIG. 10, in order to perform an information brokering service according to an embodiment of the present invention, a seller who wants to disclose his information using a computer communication network and receive a predetermined price thereof, and the sellers The purchasers who want to purchase the target information for sale are registered and managed as members, respectively (s110).

At this time, the registerable seller can be all individuals, corporations and organizations, each seller can limit the information on the sale that they want to disclose and sell.

In addition, in order to manage these sellers, the standard unit price common to all sellers is applied to the sale target information registered for each seller by the stage of the sale target information. That is, the level of information to be sold is determined by the degree of specificity of the information to be sold. For example, if any seller has disclosed whether the car is owned and the model of the car that is owned, whether the car is owned or not is the level 1 information. And the vehicle becomes two-stage information.

Meanwhile, in order to set a valuation criterion for each item of sale information, the seller stores and manages log information for analyzing the behavior and propensity of each seller on the computer communication network. That is, to store and manage mail-log information and web-log information for each seller in order to calculate a behavioral index of each seller on a computer communication network, and to calculate a suitability index of each seller for a particular portion, by seller for a corresponding sector. Store and manage propensity analysis information.

At this time, the 'behavior index' refers to determining the main contents of the seller's work through the computer communication network and the response index to the received mail by managing the details of each seller's work on the computer communication network or access history information. The 'fitness index' refers to an index for determining the degree of suitability with a buyer who wants to purchase the seller's information by judging interests of each seller.

After registering the seller and the buyer in this way waits for the purchase conditions from any buyer. When a certain buyer enters a predetermined purchase condition (S120), the seller list is searched for sellers who satisfy the purchase condition presented by the buyer by searching the registered seller information (S130).

Then, based on the sales target information for each seller registered and managed in the process (s110) and log information, after calculating the individual mediation unit price for the sales target information of the sellers included in the seller list (s140), A list of sellers, that is, a transaction DB including an individual intermediary unit price, is created (s150) and provided to the buyer (s160).

When the buyer views the seller list and selects a desired seller to apply for purchase of the corresponding information (s170), the purchaser including the individual brokerage unit price, the brokerage fee information, and the buyer information for the target seller is sent to the selected seller. Notify (s180).

The seller who confirms the individual mediation unit price for the sales target information included in the purchase history may determine the final selling unit price for the corresponding information through the price adjustment procedure (s190) with the buyer during the sale time limit set by the seller.

When the final selling price for the information is determined through the price adjustment procedure (s190) between the seller and the buyer as described above, the buyer bills the transaction (s200), and in response, the buyer pays the transaction price (s210). After accumulating the limited amount of the brokerage fee of the transaction in the seller's account (s220), the corresponding information is provided to the buyer (s230).

At this time, there are various ways to pay the seller the transaction amount accumulated for each seller's account. One method is to set the refund conditions for each seller's account, and then the total amount accumulated in the account is If the refund condition is met, the money is transferred to the deposit account designated by the seller.

11 is a flowchart illustrating a process of calculating an intermediary unit price according to an embodiment of the present invention, in which a process of calculating an intermediary unit price for each selling target information of sellers included in a seller list corresponding to a purchase condition input by a buyer is shown. .

Referring to FIG. 11, the mediation unit price calculation process s140 for each information is as follows.

First, the sum B of the standard unit prices uniformly assigned by the information intermediation system for each item of sale among the basic input information input by the seller is calculated (s141). At this time, the stage of the information to be sold is determined by the degree of specificity of the information to be sold.

Then, the behavioral index (a) of the seller is calculated based on the mail log information and the web-log information stored and managed by the seller (s142), and the seller's propensity for the specific portion is analyzed to analyze the seller for the corresponding sector. After calculating the suitability index (b) of (s143), the average value of the behavior index (a) and the suitability index (b) is set as the comprehensive evaluation index (A) (s144).

The final mediation unit price T is calculated by multiplying the sum B of the standard unit prices by the seller's comprehensive valuation index A.

The individual mediation unit price for the sales information determined through the above process may further include a separate price adjustment process according to the seller's transaction authority type set at the time of registering the seller.

12 illustrates a price adjustment process s190 according to the type of transaction authority of the seller. Referring to FIG. 12, first, a transaction authority of a seller is checked. If the seller authority is set to 'delegation' (s191, s192), the mediation unit price determined through the procedure illustrated in FIG. 11 is used as the final transaction price. (S194), if the seller's trading authority is set to 'zyme' (s191, s192), wait for the price adjustment between the seller and the buyer to complete during the time limit set by the seller, and then adjust the price when the price adjustment is completed. The final transaction price is determined (s195 to s198). If the transaction authority of the seller is 'conditional delegation', it is checked whether or not the mediation unit price set through the procedure illustrated in FIG. 11 satisfies the condition (s193). The transaction price is determined in the same manner as in the case where the transaction authority is 'Delegation' (s194), and in the same way (s195 through s198) when the transaction authority of the seller is 'zyme' when the brokerage unit price does not meet the conditions. Determine the transaction price.

13A to 13E are diagrams for describing in more detail a process of calculating an intermediary unit price for each seller according to an embodiment of the present invention. In order to send a promotional mail of a new compact car from an automobile company, ages 20 to 60 are shown. In the case of purchasing information of sellers who are aged and owned cars, the process of calculating the brokerage unit price of these sellers was described in detail.

First, FIG. 13A illustrates an example of a list of sellers first extracted as a result of searching a seller management DB based on the purchase condition (the seller is 20 to 60 years old and owns a car).

Referring to FIG. 13A, two sellers satisfying the purchase condition ('Hong Gil-dong' and 'Hwang Jin-yi'), and the selling target information that each seller wants to sell and their reference unit price are shown in FIG. 13A. These standard unit prices are the unit prices applied to all sellers in the information brokerage system. In other words, Hong Gil-dong and Hwang Jin-yi's unit price is 1,050 won. This is a price that includes a unit price of 50 won for car ownership information in the basic unit price 1,000 won.

FIG. 13B is an e-mail log analysis evaluation table of each seller included in the seller list, and the seller's response result and the index of the response contents for the e-mails received by each seller are shown in FIG. 13B. These response indices were calculated with reference to the response-specific score table for the incoming mail illustrated in FIG. 9A. The total response index of Hong Gil-dong by this calculation method is '110', and the total response index of Hwang Jin-yi is '12'.

In addition, the evaluation index of the seller by these response index is calculated by referring to the evaluation index table by response score band illustrated in FIG. 9B. As a result, the evaluation index of Hong Gil-dong based on the e-mail log information is '1.50'. The evaluation index is '1.02' (indicated in FIG. 13E).

FIG. 13C is a table for managing the average daily Internet access time of each seller based on web-log information in units of minutes, and the evaluation index for each seller by the access time is shown by access time zone illustrated in FIG. 9C. It is calculated by referring to the evaluation index table. As a result, the evaluation index of Hong Gil-dong is '1.10' and Hwang Jin-yi's evaluation index is '1.20'.

In this way, the evaluation index of each seller based on these e-mail logs and web-log information becomes a behavior index for determining the seller's behavior on the Internet.

In addition, FIG. 13D is a table for managing the number of visits and the rate of visits by the sellers to visit a vehicle-related site in order to analyze the propensity of each seller on the Internet for the automobile sector. The information managed in FIG. Based on the table, the valuation index of each seller is calculated, and Hong Gil-dong's valuation index is '1.3' and Hwang Jin-yi's valuation index is '1.2'.

Meanwhile, according to the table of available-for-purchase evaluation indexes based on the type of vehicle currently owned by FIG. 9E, Hong Gil-dong, which currently owns a 'Dynasty (large car)', can purchase a small car at '1.10' and is currently ' Hwang Jin-yi, who owns Tico (light car), can purchase small cars.

The results of the analysis of the propensity of Hong Gil-dong and Hwang Jin-yi in the automobile sector, and the evaluation index for purchasing small cars in the future, are the indices of fitness for determining the suitability between car companies and sellers extracted from the list of sellers for promoting small cars.

The reference unit price, behavioral index, and fitness index of each seller calculated in this way are collectively managed in FIG. 13E, and the average value of the behavioral index and fitness index becomes the comprehensive evaluation index of each seller, and the comprehensive evaluation index and the standard The unit price multiplied is the final mediation price. Therefore, the mediation unit price for Hong Gil-dong's target information is '1,312 won' and Hwang Jin-i's mediation unit price for the target information is '1,680 won'.

In other words, Hong Gil-dong and Hwang Jin-yi's behavioral and fitness index calculations on the Internet show that Hwang Jin-dong's information is more valuable than Hong Gil-dong's information for automobile companies that want to promote small cars. To be traded on.

The above description is merely an example of an embodiment, and the present invention is not limited to the above-described embodiment and can be variously changed within the scope of the appended claims. For example, the shape and structure of each component specifically shown in the embodiment of the present invention can be modified.
