A mapping system for the integration of OWL-DL ontologies
2005
Proceedings of the first international workshop on Interoperability of heterogeneous information systems - IHIS '05
We further show how the mapping system can be applied for the task of ontology integration and present a query answering algorithm. ...
As query answering within such a general mapping system is undecidable, we identify a decidable fragment of the mapping system, which corresponds to OWL-DL extended with DL-safe rules. ...

Using OWL in Data Integration
[chapter]
2009
Semantic Web Information Management
OWL 2 QL is one of the tractable profiles of OWL 2, and essentially corresponds to a member of the DL-Lite family, a family of Description Logics designed to have a good trade-off between expressive power ...
One of the outcomes of the research work carried out on data integration in the last years is a clear architecture, comprising a global schema, the source schema, and the mapping between the source and ...
When the global schema of a data integration system is specified in terms of a DL ontology, it is natural to look at the research carried out in the DL field and at the tools developed for specifying and ...

A decentralized infrastructure for query answering over distributed ontologies
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. ...
This infrastructure addresses (i) the coordination of multiple nodes using metadata about the provided resources managed in a decentralized registry and (ii) the mediation between heterogeneous ontologies ...
The KAONp2p has been implemented to a large extent by Rui Guo from EPFL Lausanne as part of his master's thesis at the University of Karlsruhe. ...

Research on OWL Ontology Learning Method Based on Relational Schema
2019
DEStech Transactions on Computer Science and Engineering
The method includes a set of mapping rules by which learning OWL ontology from relational schema. The mapping rule set consists of attribute axiom mapping, class axiom mapping and heuristic mapping. ...
It is found that the definition of OWL DL ontology based on description logic is similar to the formal definition of relational data schema. ...
Finally, a prototype system tool based on Java platform is used to map the case database, which proves the correctness of the mapping rules. Figure 1 . 1 ER model of database recipe. ...

System of Mediation based on Ontology to Solve the Semantic Heterogeneity between Information Systems
2013
International Journal of Computer Applications
Ontologies allow systems to use a terminology consensus. We use the mapping between different ontologies. This mapping will be used in the process of query rewriting. ...
In this article, we focus on the semantic heterogeneity between information systems and we propose a mediation system based on ontologies, to allow the integration of heterogeneous sources. ...
Integration of heterogeneous data sources module The goal of integrating heterogeneous data sources is to provide users with a consistent view of the system that uses them. ...
