We provide a set of decidability, undecidability and complexity results for answering queries of the above languages over various classes of Description Logics knowledge bases. In general, suc

We also determine which transformations preserve beads. We give conceptually easy first-order complete query languages and computationally complete query lan

Contested Transparencies: An Introduction,pe checking problem for smtts. While the problem is decidable, the involved technique of inverse type inference is known to have exponential worst-case complexity (already for top-down transformations without parameters). We present a new . type checking algorithm based on forward type inference thr

Contested Transparencies: An Introduction,e, inclusion, and non-emptiness of intersection of schemas form the basic building blocks for schema optimization and integration, and algorithms for static analysis of transformations. It is thereby paramount to establish the exact complexity of these problems. Most common schema languages for XML

Ask a Better Question, Get a Better Answer A New Approach to Private Data Analysis statistics about a population while preserving the privacy of individuals. This new perspective has been invaluable in guiding the development of a powerful approach to private data analysis, founded on precise mathematical definitions, and yielding algorithms with provable, meaningful, privacy guarantees.
