The dramatic increase in the use of knowledge discovery applications requires end users to
write complex database search requests to retrieve information. Such users are not only …

Along with the rapidly growing scale of relational database (RDB), how to construct domain-
related ontologies from various databases effectively and efficiently has been a bottleneck of …

Visual support designed to facilitate human interaction with semantic data has largely
focused on visualizing entities such as classes and relationships within an ontology …

Visual support designed to facilitate human interaction with ontological data has largely
focused on one-size-fits-all solutions, where less attention has been paid to providing …

This paper presents Map-On, a web-based editor for visual ontology map** developed by
the Architecture, Representation and Computation research group of La Salle, Ramon Llull …

Ontology-based data integration (OBDI) allows users to federate over heterogeneous data
sources using a semantic rich conceptual data model. An important challenge in ODBI is the …

In this demo, we will show the operation of Ultrawrap Mapper, a semi-automatic software for
creating map**s from Relational Databases to RDF in the R2RML language. In 2012, the …

An early vision in Computer Science was focused on Artificial Intelligence (AI) to produce
intelligent systems capable of reasoning on huge amounts of data. Since the huge amount …

R2RML defines a language to express map**s from relational data to RDF. That way,
applications built on top of the W3C Semantic Technology stack can seamlessly integrate …

For integrating relational databases (RDBs) into semantic web applications, the W3C
RDB2RDF Working Group recommended two approaches, Direct Map** (DM) and …
