Design of System for Managing Fuzzy Relationships for Integration of Spatial Data in Querying
In this paper we present the design of two essential components for the spatial querying system we have been developing. The overall system architecture utilizes multiple levels of agents to process external sources of spatial data. Upon a user query, agents are spawned to mine various web sources, integrate the spatial data and return the correctly formulated query result to the user. Here we specifically describe a rule-based component for processing spatial relationships that is used both for the active agents and at the user interface to provide a dynamic query response. We also describe the database that is being used to maintain the spatial relationships uncovered in the query. The design and implementation of the two major components, the expert system using the expert system shell Fuzzy clips and the database in a C + +, Oracle database environment, are described in some detail.
