摘要
PURPOSE: A method for deciding advertisement cost and a billing system using the method are provided to protect an advertiser by deciding rational advertisement cost for advertisement. CONSTITUTION: A counting unit(A) accumulates the number of times that keyword advertisement is offered for a certain period of time. A probability density calculating unit(B) produces regular distribution probability about the keyword advertisement being offered. The probability density calculating unit calculates the normal distribution probability using the accumulated offered times for the period of time. According to the normal distribution probability, a discount rate determining unit(507) decides the discount rate. According to the discount rate, a payment billing unit(508) decides the advertisement cost for the keyword advertisement.
