Abstract: A medical concept code analysis system includes a medical terminology source and at least one processor configured to access the medical terminology source. The processor also is configured to receive interface terminology concept code information associated with a plurality of interface terminology concept codes, receive public concept code information associated with a plurality of public concept codes, generate annotations for the plurality of public concept codes based on the public concept code information by determining a string and/or substring of the description associated with each public concept code contains an annotation that align with one or more predetermined annotation categories, associate the annotations with the plurality of interface terminology concept codes, and cause the interface terminology concept codes and the annotations to be output.

Abstract: A method and apparatus for a navigation system determines whether an upcoming cross street is meaningful for a user to be displayed. The includes the steps of searching upcoming cross streets that intersect with a current street on which a user's vehicle is running for a predetermined distance range ahead of a current vehicle position, retrieving data concerning the upcoming cross streets from the map data, determining whether a cross street is meaningful for the user to be displayed on a screen of the navigation system by applying predetermined rules to the data concerning the cross street, and displaying information on the cross street that has been determined to be meaningful for the user on the screen.
