Though visual access to spatial database systems has attracted much attention in recent years, there have only few deductive visual languages for spatial information systems been ...
We present Episodic Logic (EL), a highly expressive knowledge representation well-adapted to general commonsense reasoning as well as the interpretive and inferential needs of nat...
The efficacy of expert systems often depends on the accuracy and completeness of the problem specification negotiated with the user. Therefore, efficient user interfaces are needed...
In this paper we propose a visual interface for the specification of predicates to be used in queries on spatio-temporal databases. The approach is based on a visual specification ...
Understanding and maintenance of complex information spaces is often supported through visual interfaces. These interfaces must be highly flexible in order to adapt to both the u...
