Geographic dimensions of relevance

Recent advances in mobile technologies led to new spatially-and context-aware definitions of relevance. In this paper, we aim to develop the conceptual framework suggested by Mizzaro (1998) further, in order to improve the characterization and classification of current and future concepts of relevance. We formalise two new dimension of relevance. The first dimension emphasizes the spatio-temporal nature of the information seeking process. The second dimension is necessary to describe how different concepts of relevance rely on different abstractions of reality.
