Ontologies and semantic data integration

Semantic Data Integration on Biomedical Data Using Semantic Web Technologies

“…Semantic Web approach to data integration can deal with heterogeneity by providing structured meta-information to existing documents and data. A key feature integrating information is the use of semantics which gives meaning to a word or concept (Gardner, 2005). Semantics can solve the problem of homonyms and synonyms between different sources because it is able to ensure the equivalence of two concepts which might have different names and forms (synonyms) or the dissimilarity of two concepts which might have the same name and form (homonyms).…”

“…In this context, ontologies are used to describe the semantics of the data sources in order to make their content explicit (Boury-Brisset, 2003). The integration can take place on an extremely granular level to map data from different resources, no mater if the resources contain structured or unstructured data (Gardner, 2005).…”

Semantic Data Integration Approaches for E-Governance

“…The generation of Ontologies is an important activity to enable semantic data integration. Efficiency in data integration can be achieved by Ontologies [26]. Thus risk associated with the continual redevelopment of project-specific integration strategies can be reduced.…”

“…The formation of ontology helps a range of applications that delivers the right information at the right time to make better informed decisions throughout the lifecycle of discovery, development of various applications such as marketing, sales, public policy etc., in passing [27]. Thus a range of semantic technologies based on ontologies enable the proper integration of knowledge in a way that is reusable by several applications across governance or business from discovery to corporate affairs, explicitly as in [26].…”

Developing a Knowledge Management System Using an Ontological Approach in Global Organization

“…The data integration research trend is moving toward semantic data integration using ontology due to it having the capability of specifying relationships between concepts and facilitating reasoning [10]. In industrial practices, major information service enterprises such as Google, Yahoo and Microsoft have agreed on shared vocabularies with encoded semantics to publish the data on the Web [11].…”
