An information service system allowing a user to use user-memorable information to obtain desired information includes: a portable device referring to an input logical concept indicating a destination, such as a dining hall for breakfast, a public bath, to search for a physical concept, such as “AZALEA (corresponding to the name of a dining hall for breakfast),” a corner on the third floor, and transmit a retrieved physical concept to a stationary device installed, e.g., at an intersection of passageways in a hotel, and receiving from the stationary device a direction to be taken by the user and displaying such direction; and the stationary device searching for a direction to a physical concept and transmitting to the portable device a retrieved direction to the physical concept. The information service system also includes an association control system to rewrite an association between a logical concept and a physical concept that is stored in the portable device.
