Abstract. Disjunctive logic programs are a powerful tool in knowledge representation and commonsense reasoning. The recent development of an efficient disjunctive logic programmin...
Research on information extraction from Web pages (wrapping) has seen much activity in recent times (particularly systems implementations), but little work has been done on formal...
There is a recent trend of extending epistemic logic (EL) with dynamic operators that allow to express the evolution of knowledge and induced by knowledge-changing actions. The mo...
