KWTR: ontology interoperability
[edit] Contributors:
Oscar Corcho
- What is the state of the art of Semantic Web in your research field?
Work on ontology interoperability has focused on two main areas: interoperability between ontology tools and interoperability between ontology languages. The first area is focused on analysing how different ontology tools can exchange their ontologies by means of common (pivot) ontology languages (e.g., Ontolingua, RDFS, OWL, etc.) or by means of specific translators that make transformations between the internal knowledge model of one tool to the another. The second area is focused on analysing the losses of expressiveness and reasoning capabilities that are related to the transformation of ontologies from one knowledge representation language to another. In this description we focus on the second area, since the first one is covered by the work done in ontology tool benchmarking.
- Provide references and short abstracts of three papers you consider as significant in your research field.
Corcho O, Gómez-Pérez A (2008) ODEDialect: a set of declarative languages for implementing ontology translation systems. Journal of Universal Computer Science. To appear. This paper describes ODEDialect, a set of languages to make declarative transformations between knowledge representation languages.

In: Omelayenko B, Klein M (eds) Knowledge transformation for the semantic web, IOS press, Amsterdam, The Netherlands, pp 49-63. This paper describes an approach based on having families of languages to represent formally the transformations that can be done between KR languages.
Baader F (1996) A Formal Definition for the Expressive Power of Terminological Knowledge Representation Languages. Journal of Logic and Computation 6(1):33–54. This paper describes a formal approach to compare the expressive power of different knowledge representation languages based on description logic.
- Please provide one or more examples (either business, or research, or both) in which semantic web has been used (if you can, add some references).
Ontology interoperability has been used in any case where an ontology that has to be reused is available in a language different to the one in which the ontology needs to be exploited.
- Are there existing tools or demos? Please indicate some of them.
ODEDialect, Transmorpher and OntoMorph.
- What are the open problems in your Semantic Web research field? Why?
With the standardisation of knowledge representation languages like RDFS and OWL, the need for these kinds of tools and approaches has been minimised.
- Provide references and links of the most relevant Semantic Web research projects in your field.
No active projects are working in this area.
- What challenges try these projects to overcome?
--
- What are their foreseen benefits (both in market and scientific community)?
--
- When, in your opinion, will projects’ results be ready for industry?
--
- Do you think that it is important to invest (money and time) in these topics? Why?
No, since the standardisation effort in Semantic Web languages has made this effort not so needed for ontology-based system development.
- What are, in your opinion, the most relevant Semantic Web challenges that will be solved in the long term (10 years)? Why?
