PURPOSE: A method and a device for recommending an area where relative interest has been increased are provided to compare a ratio between a search quantity during a constant time and a search quantity which has been recently searched, thereby recommending the interest area which interest has been recently increased in the short time. CONSTITUTION: A monitoring unit(101) divides an area for searching into certain size of a grid. The monitoring unit monitors a quantity which a point of interest is searched in the gird. An interest increase grid calculating unit(102) analyzes the quantity which the point of interest is searched to calculate the gird which interest has been increased. A center calculator(103) calculates the center point of the grid which the interest has been increased. An interest increase area calculator(104) calculates an interest increase area including at least one of a point of interest based on the center point. |
