Ontology based framework for data integration
TL;DR: This paper describes a framework which encompasses the entire data integration process and the data source schemas as well as the integrated schema are expressed using an extension of an ontology definition language which allows the incorporation of metadata to support the integration process.

Abstract: One of the most complex issues of the data integration is the case where there are multiple sources for the same data element It is not easy to generate and maintain the integrated scheme In this paper we describe a framework which encompasses the entire data integration process The data source schemas as well as the integrated schema are expressed using an extension of an ontology definition language which allows the incorporation of metadata to support the integration process The proposed model allows the user to concentrate in modeling the problem itself and not in the issues of dealing with the temporal and the spatial aspects concerning to many of the data sources usually used in the enterprises information systems

Developing ontology based applications with O3L
TL;DR: This software library, called O3L (Object-Oriented Ontology Library), provides a complete representation of ontologies compliant with OWL 2 W3C and has been experimented in the realization of some e-business applications showing both high effortlessness in the development of the applications and high performances in their execution.

Considering application domain ontologies for data mining
TL;DR: This paper describes a research of an ontological approach for leveraging the semantic content of ontologies to improve knowledge discovery in databases and analyzes how ontologies and knowledge discovery process may interoperate.
Ontological on-line analytical processing for integrating energy sensor data
TL;DR: The OLAP data cube in the framework annotated with semantics with other supporting mechanisms can deal with the issues of the schema inconsistency that may result from integration of heterogeneous data sources.

Using perspective schema and a reference model to design the ETL process
Valéria Magalhães Pequeno
- 01 Jan 2011
TL;DR: This work proposes a declarative approach based on the creation of a reference model and perspective schemata in order to make the relationship betweenschemata explicit, and makes the mappings that exist in data integration systems clear, and uncouples them inorder to make their maintenance easier.
