RDF-Based Schema Mediation for Database Grid
Fifth IEEE/ACM International Workshop on Grid Computing, 2005In presence of Grid where a huge amount of databases can be involved in sharing cycle, database tools and middlewares should be well suited for schema mediation and query processing in a semantically meaningful way. Dart is an implemented prototype system whose goal is to provide a semantic solution for database resource sharing capable of deployment ...

Revealing the Conceptual Schemas of RDF Datasets
2019RDF-based datasets, thanks to their semantic richness, variety and fine granularity, are increasingly used by both researchers and business communities. However, these datasets suffer a lack of completeness as the content evolves continuously and data contributors are loosely constrained by the vocabularies and schemes related to the data sources ...

Incremental Schema Discovery at Scale for RDF Data
2021The lack of a descriptive schema for an RDF dataset has motivated several research works addressing the problem of automatic schema discovery. The goal of these approaches is to generate a structural schema of a given RDF dataset from its instances. However, as new instances are added, the generated schema may become inconsistent with the dataset.

RDF Schema Based Ubiquitous Healthcare Service Composition
2005We suggest a service framework and algorithms of provisioning healthcare services in a ubiquitous computing environment. In order to meet customers' need we translate the need into relevant goal and repeatedly refine the goal into sub-goals through commonsense knowledge until there are appropriate services for sub-goals and after, employ the services ...

A Proposal for Management of RDF and RDF Schema Metadata in MOF
2003This paper proposes two MOF metamodels to support the representation and management of RDF and RDF Schema metadata. A metamodel is a set of related metadata used to build models. The MOF defines an abstract language and a framework to support the specification, implementation and ma-nagement of platform independent metamodels.

Design of Storage Structure for Path-Based Query on RDF and RDF Schema
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2006In the Semantic Web, metadata and ontology for representing semantics and conceptual relationships of information resources are essential factors. RDF and RDF Schema are the W3C standard models for describing metadata and ontology. In this paper, we focus on a result of analyzing available query patterns considering both RDF and RDF Schema.

Schema-agnostic ranking of RDF properties
2015In many Semantic Web applications, having RDF predicates sorted by significance is of primarily importance to improve usability and performance. In this paper we focus on predicates available on DBpedia, the most important Semantic Web source of data counting 583 million English triples.
