This paper proposes a spatial functional representation intended to explicitly describe spatial meaning in our daily life and to utilize it for advanced location-based information services. The merit of our representation is threefold: (i) it considers a space as an artifact; a space is described from its function, property and structure. (ii) a space has different meanings to different persons; thus our representation conditions a spatial function by user type. (iii) not only physical function but also social function is considered; a space has a social meaning, and our representation describes spatial meaning both physically and socially. We detail the representation and show an application of an advanced navigation, what we call spatial function retrieval, by reasoning based on that representation.
