Verification of qualitative Z constraints
We introduce an LTL-like logic with atomic formulae built over a constraint language interpreting variables in Z. The constraint language includes periodicity constraints, comparis...

A new way of optimizing OLAP queries
For around 10 years, the academic research in database has attempted to define a commonly agreed logical modeling for the multidimensional and hierarchical nature of data manipulat...

Some Logical Properties of Nonmonotonic Causal Theories
The formalism of nonmonotonic causal theories (Giunchiglia, Lee, Lifschitz, McCain, Turner, 2004) provides a general-purpose formalism for nonmonotonic reasoning and knowledge repr...

The Structure of First-Order Causality
Game semantics describe the interactive behavior of proofs by interpreting formulas as games on which proofs induce strategies. Such a semantics is introduced here for capturing d...

Query Evaluation in Peer-to-Peer Networks of Taxonomy-Based Sources
We consider the problem of query evaluation in Peer-to-Peer (P2P) systems that support semantic-based retrieval services. We confine ourselves to the case where the peers employ t...
