Integrating ontology languages and answer set programming

S. Heymans, D. Vermeir
14th International Workshop on Database and Expert Systems Applications, 2003. Proceedings.  
We integrate ontology languages and logic programming (LP) by extending disjunctive logic programs (DLPs) and their semantics in order to support inverses and an infinite universe, without introducing  ...  We show that this extension is still decidable, and can be used to simulate, on the one hand, answer set programming with a finite universe, and on the other hand, several expressive description logics  ...  The extension effectively integrates ontology languages with answer set programming, and allows for representing and reasoning with knowledge in an intuitive, expressive and unified way.  ...

Flexible Intensional Query-Answering for RDF Peer-to-Peer Systems [chapter]

Zoran Majkić
2006 Lecture Notes in Computer Science  
Such language can be used in order to define richer RDF ontologies, and to give them the expressive power of FOL data integration systems.  ...  This needs a bridge between RDFS and FOL theory. The embedding presented in this paper can be used to efficiently answer conjunctive queries in heterogeneous P2P settings.  ...  A class in programming languages is regarded as a set, and an instance of the class is a member of the set.  ...

Reformulating Action Language $\mathcal{C}$ + in Answer Set Programming [chapter]

Joohyung Lee
2012 Lecture Notes in Computer Science  
Third, the reformulation allows us to compute integration of TAL and ontologies using answer set solvers, and we illustrate its usefulness in the healthcare domain in the context of medical expert systems  ...  We present a reformulation of TAL in Answer Set Programming (ASP), and discuss some synergies it brings. First, the reformulation provides a means to compute TAL using efficient answer set solvers.  ...  Acknowledgements We are grateful to Jonas Kvarnström for his help on using VITAL and TALPlanner, and for answering our related questions.  ...

A decentralized infrastructure for query answering over distributed ontologies

Peter Haase, Yimin Wang
2007 Proceedings of the 2007 ACM symposium on Applied computing - SAC '07  
Our approach is based on a virtual integration that exhibits a semantics as if all ontologies were integrated locally.  ...  Practically, the distributed ontologies still reside on the remote peers, and only the parts relevant for answering the query need to be retrieved to the local node.  ...  Acknowledgments Research reported in this paper has been partially financed by the EU in the IST projects SEKT (IST-2003-506826, http://www. sekt-project.com/) and NeOn (IST-2006-027595, http: //www.neon-project.org  ...
