We study the expressive power of the logics EF + F-1 , 2 and boolean combinations of 1 over ranked trees. In particular, we provide effective characterizations of those three logic...
In this paper we reconsider the definition of counts-as relations in normative multiagent systems: counts-as relations do not always provide directly act interpretation of brute fa...
Abstract. Logical architectures combine several logics into a more complex logical system. In this paper we study a logical architecture using input/output operations corresponding...
Abstract. In this paper, following the work of Hare, we consider moral reasoning not as the application of moral norms and principles, but as reasoning about what ought to be done ...
Abstract. The paper describes HıLεX, a new ASP-based system for the extraction of information from unstructured documents. Unlike previous systems, which are mainly syntactic, HÄ...

We study logical principles connecting two relations: independence, which is known as nondeducibility in the study of information flow, and functional dependence. Two different e...

Existing action calculi provide rich, declarative formalisms for reasoning about actions. BDI-based programming languages like AgentSpeak, on the other hand, are procedural and ge...
We show how the reasoning tasks of checking various versions of conservativity for the description logic DL-Litebool can be reduced to satisfiability of quantified Boolean formulas...
