Fuzzy conditional temporal problems: Strong and weak consistency
: In real life scenarios there is often the need for modelling conditional plans where external events determgine the actual execution sequence. Conditional Temporal Problems (CTPs...

First-Order Query Rewriting for Inconsistent Databases
We consider the problem of retrieving consistent answers over databases that might be inconsistent with respect to some given integrity constraints. In particular, we concentrate o...
