Automated Database Mediation Using Ontological Metadata Mappings

Automated Database Mediation Using Ontological Metadata Mappings

Background: One challenge of database federation is that the granularity of representation of equivalent data varies across systems. Dealing effectively with this problem is analogous to dealing with precoordinated vs. postcoordinated concepts in biomedical ontologies. Model Description: The authors describe an approach based on ontological metadata mapping rules defined with elements of a glob...

Ontological Mediation :

Algorithms for Ontological Mediation

We lay the foundation for ontological mediation as a method for resolving communication difficulties resulting from different ontologies. The notion of hierarchical relations enables a theory of orientation or direction of ontologies to be presented. We describe an ontologcial mediator as being able to think about (or conceptualize) concepts from ontologies and find equivalences between them. A...

Ontological Mappings of Product Catalogues

In this paper we built on top of recent effort in the areas of semantics and interoperability to establish the basis for a comprehensive and sustainable approach to the development and later management of bridging systems among a variety of corporate system that need to be interconnected without being individually modified. In particular, we collect some preliminary evidence that a sustainable ...

An Ontological Approach to Intelligence Gathering using Semantic Metadata

We discuss our research into combatting the problem of effectively presenting next to real-time knowledgeable answers to runtime user generated queries, from disparate sources. The paper explores the foundations of our research for the design of an Information Gathering tool based on the Intelligence Domain; focusing on the exploration of semantic metadata, incorporating ontologies and implemen...
