Abstract

Data warehouses are being considered as substantial elements for
decision support systems. They are usually structured according to the
multidimensional paradigm, i.e. datacubes. Geospatial datacubes contain
geospatial components that allow geospatial visualization and aggregation.
However, the simultaneous use of multiple geospatial datacubes, which may be
heterogeneous in design or content, drives to consider interoperability between
them. Overcoming the heterogeneity problems has been the principal aim of
several research works for the last fifteen years. Among these works, the
geosemantic proximity notion (GsP) represents a qualitative approach to
measure the semantic similarity between geospatial concepts. The GsP, which
has been defined in the transactional context, and can be used to a certain extent
in the multidimensional paradigm, needs to be revisited to be more suitable for
this paradigm. This paper proposes an extension to the GSP notion in order to
support the semantic interoperability between multidimensional geospatial
datacubes. The extension, called MGsP, aims to give the possibility to dig into
and resolve semantic heterogeneity related to key notions of the
multidimensional paradigm.
