Top-k Spatial Preference Queries [PDF]
2007 IEEE 23rd International Conference on Data Engineering, 2007 A spatial preference query ranks objects based on the qualities of features in their spatial neighborhood. For example, consider a real estate agency office that holds a database with available flats for lease. A customer may want to rank the flats with respect to the appropriateness of their location, defined after aggregating the qualities of other ...
