Mapping Relational Database into OWL Structure with Data Semantic Preservation
This paper proposes a solution for migrating an RDBMS into an appropriate structure for the Semantic Web (i.e., RDF). The solution takes an existing RDBMS [...]
Capturing Relational Schemas and Functional Dependencies in RDFS
Mapping relational data to RDF is an important task for the development of the Semantic Web. To this end, the W3C has recently released a [...]
Accessing Relational Data with RDF Queries and Assertions
This paper presents a hybrid RDF storage model that combines relational data with arbitrary RDF metadata, as implemented in the RDF storage layer of the [...]
RDF and Logic: Reasoning and Extension
This paper explores embedding the various kinds of RDF entailment in F-Logic. It shows that the embedding of simple, RDF, and RDFS entailment, as well [...]
Expressive Languages for Querying the Semantic Web
SPARQL 1.1 was recently released, which includes entailment regimes for RDFS and OWL vocabularies and a mechanism to express navigation patterns through regular expressions. Unfortunately, [...]
Learning from the Masters: Understanding Ontologies found on the Web (Part 1)
