Abstract. For practical applications, the use of top-down query-driven proofprocedures is essential for an efficient use and computation of answers using Logic Programs as knowledg...
Recent years have witnessed the wide recognition of the importance of ontology and rule in the AI research. In this paper, we report our implementation and evaluation of a rule-ba...
We consider the problem of answering datalog queries using materialized views. The ability to answer queries using views is crucial in the context of information integration. Prev...
Given two classes of logic programs, we may be interested in modular translations from one class into the other that are sound wth respect to the answer set semantics. The main the...
Abstract. This paper presents a decidable fragment for combining ontologies and rules in order-sorted logic programming. We describe ordersorted logic programming with sort, predic...
