Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

CLAIMS
1. A method of determining an advertising fee in a shopping related site, the method comprising:
maintaining a fee information database which stores a graded fee rate according to each of a plurality of price ranges which are divided according to a predetermined standard;
classifying a selling price of a product into at least one unit price by considering the divided price ranges;
calculating a unit fee for each of the price ranges by using a unit price in each of the price ranges, and the graded fee rate corresponding to each of the price ranges which is identified from the fee information database; and
determining the advertising fee by summing up the calculated unit fee of each of the price ranges.

2. The method of claim 1 , wherein the calculating comprises:
comparing the selling price P with any one of a lowest selling price m and a highest selling price M which are included in a particular price range;
calculating the unit fee C of the price range according to 'C=(P-m)*G', when the selling price P satisfies 'm≤P<M' as a result of the comparison, the G designating the graded fee rate corresponding to the price range.

3. The method of claim 1 , wherein the calculating comprises:
comparing the selling price P with any one of a lowest selling price m and a highest selling price M which are included in a particular price range; and
calculating the unit fee C of the price range according to 'C=(M-m)*G', when the selling price P satisfies 'M≤P' as a result of the comparison, the G designating the graded fee rate corresponding to the price range.

4. The method of claim 1, wherein the calculating comprises:
comparing the selling price P with any one of a lowest selling price m and a highest selling price M which are included in a particular price range; and
calculating the unit fee of the price range as O', when the selling price P satisfies T<nϊ as a result of the comparison.

5. The method of claim 1, wherein the plurality of price ranges is divided by performing:
classifying at least one product into a single category by considering features of the product;
verifying a selling price range of the category from a highest selling price and a lowest selling price of products which are included in the category; and
determining the verified selling price range as the standard.

6. The method of claim 1, wherein the plurality of price ranges is divided by performing:
classifying at least one product into a single category by considering features of the product;
arranging the at least one product, which is included the category, based on the selling price of the at least one product;
sequentially selecting selling prices based on a number of the arranged products, and summing up a number of products which are arranged in the selected selling price; stopping the selecting of the selling price, when a ratio of the summed number of products to the number of products included in the category is greater than a predetermined numerical value; and
determining an upper limit and a lower limit of the selected selling price as the standard before the stopping.

7. The method of claim 1, further comprising:
receiving a product information request including a product identifier of the product, from a purchaser;
transmitting advertising information associated with the product identifier to the purchaser, in response to the received product information request; and
verifying the purchaser's click on the advertising information, and charging an advertiser of the clicked advertising information with the determined advertising fee.

8. A computer-readable record medium storing a program for implementing the method according to any one of claims 1 through 7.

9. A system for determining an advertising fee in a shopping related site, the system comprising:
a fee information database storing a graded fee rate according to each of a plurality of price ranges which are divided according to a predetermined standard;
a price range classification unit classifying a selling price of a product into at least one unit price by considering the divided price ranges;
a unit fee calculation unit calculating a unit fee for each of the price ranges by using a unit price in each of the price ranges, and the graded fee rate corresponding to each of the price ranges which is identified from the fee information database; and
a fee determination unit determining the advertising fee by summing up the calculated unit fee of each of the price ranges.

10. The system of claim 9, wherein the unit fee calculation unit compares the selling price P with any one of a lowest selling price m and a highest selling price M which are included in a particular price range, and calculates the unit fee C of the price range according to 'C=(P-m)*G', when the selling price P satisfies m≤P<M' as a result of the comparison, the G designating the graded fee rate corresponding to the price range.

11. The system of claim 9, wherein the unit fee calculation unit compares the selling price P with any one of a lowest selling price m and a highest selling price M which are included in a particular price range, and calculates the unit fee C of the price range according to 'C=(M-m)*G', when the selling price P satisfies 'M≤P' as a result of the comparison, the G designating the graded fee rate corresponding to the price range.
