Extracting the relevant information by exploiting the spatial data warehouse becomes increasingly hard. In fact, because of the enormous amount of data stored in the spatial data warehouse, the user, usually, don't know what part of the cube contain the relevant information and what the forthcoming query should be. As a solution, the authors propose to study the similarity between the behaviors of the users, in term of the spatial MDX queries launched on the system, as a basis to recommend the next relevant MDX query to the current user. This paper introduces a new similarity measure for comparing spatial MDX queries.
