Abstract

Knowledge-based cooperative query answering facilities have been introduced to the GIS for approximate query answering. We use context-sensitive spatial type abstraction hierarchies to provide such cooperative capabilities. As a result, the ranges of the approximate spatial operators can be automatically determined by STAHs, rather than specified by domain experts. Thus these operators are context-sensitive. Further, STAHs can be generated automatically from geographic databases and thus is scalable. A prototype system, CoGIS, has been implemented to incorporate these cooperative capabilities.
