PROBLEM TO BE SOLVED: To classify a learned keyword in semantic units for intelligible display. SOLUTION: When a user inputs a query word, a navigation device retrieves location information by using the query word and shows it to the user. The user selects the shown location information and sets a destination. A search key is set in the location information to hit the query word, and the search key is classified considering the semantic unit as a classification unit. The navigation device classifies the query word input by the user by using the classification in the search key of the location information set as the destination, and stores the result as a learned keyword to learn. Thus, the navigation device classifies the query word input by the user according to the search key of the location information selected by the user to thereby generate a learned keyword classified considering the semantic unit.
