A modular approach to defining and characterising notions of simulation
We propose a modular approach to defining notions of simulation, and modal logics which characterise them. We use coalgebras to model state-based systems, relators to define notio...

Vague Knowledge Bases for Matchmaking in P2P E-Marketplaces
In this paper we propose an approach to semantic matchmaking that exploits various knowledge representation technologies to find most promising partners in peer-to-peer e-marketpl...

Implicit Program Synthesis by a Reversible Metainterpreter
Synthesis of logic programs is considered as a special instance of logic programming. We describe experience made within a logical metaprogramming environment whose central compone...

EVOLP: Tranformation-Based Semantics
Over the years, Logic Programming has proved to be a good and natural tool for expressing, querying and manipulating explicit knowledge in many areas of computer science. However, ...

Valiant-Vazirani Lemmata for Various Logics
We show analogues of a theorem due to Valiant and Vazirani [16] for intractable parameterized complexity classes such as W[P], W[SAT] and the classes of the W-hierarchy as well as...
