Supporting Data Integration Tasks with Semi-Automatic Ontology Construction
Rizkallah Touma, Oscar Romero, Petar Jovanović · 2015
Data integration aims to facilitate the exploitation of heterogeneous data by providing the user with a unified view of data residing in different sources. Currently, ontologies are commonly used to represent this unified view in terms of a global target schema due to their flexibility and expressiveness. However, most approaches still assume a predefined target schema and focus on generating the mappings between this schema and the sources.
