1994 Proceedings of the third international conference on Information and knowledge management - CIKM '94  
We propose a pattern matching language for spatio-temp-  ...  We have presented a language for navigation within a tu- ple/object based upon patterns for spatio-temporal databases. These patterns have two space-dimensions and one time- dimension.  ...  In this section we present the language for construct- ing spatio-temporal patterns, of which, temporal patterns, spatial pat t ems are special cases.  ...

Semantic Mappings in Description Logics for Spatio-temporal Database Schema Integration [chapter]

A. Sotnykova, C. Vangenot, N. Cullot, N. Bennacer, M-A. Aufaure
2005 Lecture Notes in Computer Science  
Reconciling this heterogeneity to build a fully integrated database is known to be a complex and currently unresolved problem, and few formal approaches exist for the integration of spatio-temporal databases  ...  One of the most representive realms of diversity of data representation is the spatio-temporal domain.  ...  Our proposal focuses on the co-operation of spatio-temporal databases. In this respect, our objective is to propose a complete methodology for the integration of spatio-temporal conceptual schemas.  ...

Spatio-temporal Indexing in Database Semantics [chapter]

Roland Hausser
2001 Lecture Notes in Computer Science  
In logic, the spatio-temporal location of a proposition is characterized precisely within a Cartesian system of space and time coordinates.  ...  Such an analysis is important for modeling natural language communication because spatio-temporal information is constantly coded into language by the speaker and decoded by the hearer.  ...  For this, a propositional content's spatio-temporal location is characterized in the database of the speaker, (ii) coded into the language sign, (iii) reconstructed by hearer, and (iv) and represented  ...
