[PDF] OntoGrate: Towards Automatic Integration for Relational Databases and the Semantic Web through an Ontology-based Framework
[PDF] from stanford.eduD Dou, H Qin... - Dou Dejing, Qin Han, Lependu Paea// ..., 2010 - stanford.edu
Integrating existing relational databases with ontology-based systems is among the
important research problems for the Semantic Web. We have designed a comprehensive
framework called OntoGrate which combines a highly automatic mapping system, a logic ...
