  • Flouris: Mind the (Intelligibility) Gap  
  • by Yannis Tzitzikas, Giorgos Flouris — 2007 — 11th European Conference on Research and Advanced Technology for Digital Libraries, ECDL’2007
  • …Abstract. Intelligibility, evolution and emulation are some of the key notions for digital information preservation. In this paper we define formally these notions on the basis of modules and inter-module dependencies. Subsequently, we discuss how we can handle the evolution of modules and dependenc…

  • Inconsistencies, negation and changes in ontologies  
  • by Giorgos Flouris, Zhisheng Huang — 2006 — In Proc. of AAAI’06
  • …Ontology management and maintenance are considered cornerstone issues in current Semantic Web applications in which semantic integration and ontological reasoning play a fundamental role. The ability to deal with inconsistency and to accommodate change is of utmost importance in realworld applicatio…

  • On Belief Change and Ontology Evolution  
  • by Giorgos Flouris, Giorgos Flouris, Dimitris Plexousakis — 2006 — University of Crete
  • …One of the crucial tasks to be performed towards the realization of the vision of the Semantic Web is the encoding of human knowledge in special structures (ontologies), using formal representation languages. Simply creating an ontology is not enough though; knowledge needs to be updated as well. Th…

  • Describing Knowledge Representation Schemes: a Formal Account  
  • by Giorgos Flouris, Dimitris Plexousakis, Grigoris Antoniou — 2003 — URL: http://www.ics.forth.gr/isl/publications/paperlink/TR320April2003.pdf
  • …Abstract. The representation and manipulation of knowledge has been drawing a great deal of attention since the early days of computer science, resulting in the introduction of numerous different Knowledge Representation schemes (KRschemes). Given the great variety of such available schemes, it woul…

  • Updating description logic using the agm theory  
  • by Giorgos Flouris, Dimitris Plexousakis, Grigoris Antoniou — 2005 — In 7th International Symposium on Logical Formalizations of Commonsense Reasoning
  • …We consider the use of belief change techniques to address the problem of updating Knowledge Bases (KBs) based on Description Logics (DLs). We focus on the feasibility of the application of the AGM theory in DL KBs, evaluate the difficulties of the approach and determine the applicability of the met…

  • Updating DLs Using the AGM Theory: A Preliminary Study  
  • by Giorgos Flouris, Dimitris Plexousakis, Grigoris Antoniou — 2005 — In Proceedings of the Poster Session of the 2005 Description Logic Workshop (DL-05
  • …The problem of updating DL KBs in the face of new information has received inadequate attention in the relevant literature. We believe that the problem is not significantly different from the general problem of belief change, so one possible way of addressing it would be to migrate techniques from t…

  • On Applying the AGM Theory to DLs and OWL  
  • by Giorgos Flouris, Dimitris Plexousakis, Grigoris Antoniou — 2005 — In 4th International Semantic Web Conference (ISWC
  • …Abstract. It is generally acknowledged that any Knowledge Base (KB) should be able to adapt itself to new information received. This problem has been extensively studied in the field of belief change, the dominating approach being the AGM theory. This theory set the standard for determining the rati…

  • Generalizing the AGM Postulates: Preliminary Results and Applications  
  • by Giorgos Flouris, Dimitris Plexousakis, Grigoris Antoniou — 2004 — In Proceedings of the 10th International Workshop on Non-Monotonic Reasoning (NMR 2004
  • …One of the crucial actions any reasoning system must undertake is the updating of its Knowledge Base (KB). This problem is usually referred to as the problem of belief change. The AGM approach, introduced in (Alchourron, Gärdenfors, and Makinson 1985), is the dominating paradigm in the area but it m…

  • Evolving Ontology Evolution  
  • by Giorgos Flouris, Dimitris Plexousakis, Grigoris Antoniou — 2006 — In Proceedings of the 32 nd International Conference on Current Trends in Theory and Practice of Computer Science (SOFSEM-06), Invited Talk
  • …Abstract. One of the crucial tasks towards the realization of the Semantic Web vision is the efficient encoding of human knowledge in ontologies. Thus, the proper maintenance of these, usually large, structures and, in particular, their adaptation to new knowledge (ontology evolution) is one of the …
