Abstract: In the embodiment of the present disclosure, first, the navigation device acquires the destination set by the user. Next, the navigation device acquires information about available parking spaces accessible from the roads for each road near the destination. Then, the navigation device selects a road with a predetermined number or more of accessible vacant parking spaces as a guidance destination for the vehicle.

Abstract: When there are no evaluation values from a user who has evaluated both contents X and Z, an indirect similarity calculation unit 32 of an arithmetic processing unit 30 of an information processing center 10a indirectly calculates the similarity between the contents X and Z using evaluation values of a content Y whose evaluation value is present from a user who has evaluated both the contents X and Y and whose evaluation value is present from a user who has evaluated both the contents Y and Z. A predicted evaluation value calculation unit 33 calculates a predicted evaluation value from a user who has not evaluated either of the contents X and Z using the similarity between the contents X and Z calculated by the indirect similarity calculation unit 32 and the evaluation values of the contents X and Z. Thus, it is possible to calculate the predicted evaluation values of the contents X and Z which are not directly calculable.

Abstract: A map information display apparatus includes: a display device that displays map information including a map and facility information; and a navigation device which, when a specific facility and a peripheral facility existing within a set distance of the specific facility are included in the map information displayed by the display device, displays specific facility information indicating the specific facility and peripheral facility information indicating the peripheral facility integrally on the map.
