D(k)-Index: An Adaptive Structural Summary for Graph-Structured Data
To facilitate queries over semi-structured data, various structural summaries have been proposed. Structural summaries are derived directly from the data and serve as indices for ...

Terminological Default Reasoning about Spatial Information: A First Step
We extend the theory about terminological default reasoning by using a logical base language that can represent spatioterminological phenomena. Based on this description logic lang...
