Representing Expectations in Spatial Information Systems: A Case Study
Steven Woods and
Graham Williams (CSIRO Australia)
Abstract
Expectations are important in reasoning. They provide a framework
within which decisions can be made. This paper describes a spatial
information system which couples a large object-oriented spatal
database with a graphical user interface, and incorporates ideas from
artificial intelligence research, allowing the representation and use
of expectations. In particular, the decision support role of spatial
information systems is enhanced by the incorporation of reasoning with
justifications and truth maintenance. The resulting system
facilitates the assimilation, handling, and access to large amounts of
dynamic and static data for decision support. Inferential informatoin
of an application can be recorded, monitored, and updated.
