Complexity of Axiom Pinpointing in the DL-Lite Family of Description Logics
We investigate the complexity of axiom pinpointing for different members of the DL-Lite family of Description Logics. More precisely, we consider the problem of enumerating all mi...

Transforming co-NP Checks to Answer Set Computation by Meta-Interpretation
Many NP-complete problems can be encoded in the answer set semantics of logic programs in a very concise way, where the encoding reflects the typical “guess and check” nature ...

Compile-time Computation of Polytime Functions
: We investigate the computational power of C++ compilers. In particular, it is known that any partial recursive function can be computed at compile time, using the template mechan...

Towards practical feasibility of core computation in data exchange
Abstract. Core computation in data exchange is concerned with materializing the minimal target database for a given source database. Gottlob and Nash have recently shown that the c...
