Unity is an architecture for integrating relational databases that performs three processes: metadata capture, semantic integration, and query formulation and execution. The found...
Description logics have been designed and studied in a modular way. This has allowed a methodic approach to complexity evaluation. We present a way to preserve this modularity in ...
We introduce and use a new methodology for the study of logics for action and change. The methodology allows one to define a taxonomy of reasoning problems, based in particular on...
