Integrating Ontological Data Sources Using Viewpoints-Based Approach

Integrating Ontological Data Sources Using Viewpoints-Based Approach

Within the development of Internet and intranets, information integration from various data sources becomes increasingly important and more challenging issue. Recently, the trend in data integration has favored the semantic integration using ontologies. However, the existing ontology-based approaches do not support the aspect of data multi-representations, which is important in the development ...

Integrating Distributed Data Sources Using Federated Objects

We address the problem of integrating heterogeneous data sources for collaborative environments such as Groupware systems. Pre-existing related distributed data is modeled by a composite object, where each data source is treated as a fragment of the composite object. We define a collection of methods which allow manipulation of the related distributed data in a controlled and consistent manner....

Ontological Re-classification of Individuals: A Multi-viewpoints Approach

MIRSOFT: mediator for integrating and reconciling sources using ontological functional dependencies

Providing automatic integration solutions is the key to the success of applications managing massive amounts of data. Two main problems stand out in the major studies: i the management of the source heterogeneity ii the reconciliation of query results. To tackle the first problem, formal ontologies are used to explicit the semantic of data. The reconciliation problem consists in deciding whethe...
