Discovering Mappings between Ontologies in Semantic Integration Process
نویسندگان
چکیده
The use of ontologies in semantic translation is a viable approach to overcome the problem of semantic heterogeneity. In our framework (called GeoNis) for GIS interoperability, based on Semantic Mediator, semantic heterogeneity is resolved by using a hybrid ontology approach. This paper presents our approach to mappings between community terminologies (local ontologies) and mappings between local ontology and top-level ontology. As a main contribution, paper defines offline discovering of mappings between concepts from two local ontologies.

Discovering and Maintaining Semantic Mappings between XML Schemas and Ontologies
There is general agreement that the problem of data semantics has to be addressed for XML data to become machine-processable. This problem can be tackled by defining a semantic mapping between an XML schema and an ontology. Unfortunately, creating such mappings is a tedious, time-consuming, and error-prone task. To alleviate this problem, we present a solution that heuristically discovers seman...
متن کاملDiscovering Executable Semantic Mappings Between Ontologies
Creating executable semantic mappings is an important task for ontology-based information integration. Although it is argued that mapping tools may require interaction from humans (domain experts) for best accuracy, in general, automatic ontology mapping is an AI-Complete problem. Finding matchings (correspondences) between the concepts of two ontologies is the first step towards solving this p...
متن کاملModel-theoretic Approaches to Semantic Integration
Many tasks require correct and meaningful communication and integration among intelligent agents and information resources. A major barrier to such interoperability is semantic heterogeneity: different applications, databases, and agents may ascribe disparate meanings to the same terms or use distinct terms to convey the same meaning. The development of ontologies has been proposed as a key tec...
متن کاملWhat Four Million Mappings Can Tell You about Two Hundred Ontologies
The field of biomedicine has embraced the Semantic Web probably more than any other field. As a result, there is a large number of biomedical ontologies covering overlapping areas of the field. We have developed BioPortal— an open community-based repository of biomedical ontologies. We analyzed ontologies and terminologies in BioPortal and the Unified Medical Language System (UMLS), creating mo...
متن کاملDiscovering Simple Mappings Between Relational Database Schemas and Ontologies
Ontologies proliferate with the growth of the Semantic Web. However, most of data on the Web are still stored in relational databases. Therefore, it is important to establish interoperability between relational databases and ontologies for creating a Web of data. An effective way to achieve interoperability is finding mappings between relational database schemas and ontologies. In this paper, w...
