The means 40 acquires taste information geographically near to the current position and stored in the means 10 and taste information belonging to the same category as the current position category. Characteristic values are calculated from a rate including geographic nearness and the current place category based on the acquired taste information and the highest characteristic value is set up as an estimated value. |
