Design of Storage Structure for Path-Based Query on RDF and RDF Schema

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2006
In 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.

RDF-Based Schema Mediation for Database Grid

Fifth IEEE/ACM International Workshop on Grid Computing, 2005
In 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 ...

A Transformation from RDF Documents and Schemas to Relational Databases

2007 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing, 2007
At present, resource description framework (RDF) documents and schemas (RDFS) are used to describe information in the semantic Web. Many research works regard the RDF/RDFS documents as databases and proposed data manipulations for them. This research paper takes a different approach.

A Peer-to-Peer Information Sharing Method for RDF Triples Based on RDF Schema

2009
Managing and sharing RDF triples in a distributed environment is one of the important issues for realizing semantic information retrieval in the Internet. Especially, the notion of RDF classes plays an important role in semantic information retrieval. In this paper, we propose a peer-to-peer information sharing method for RDF triples based on RDF class

Investigating Schema Definitions Using RDFS and OWL 2 for RDF Databases in Life Sciences

2020
With the development of measuring instruments, life science databases are becoming larger and more heterogeneous. As a step towards providing integrated databases, many life science databases have been published as Linked Open Data (LOD). To utilize such databases efficiently, it is desirable that the schema, such as class–class relations, can be ...

Integrating Ontologies and Thesauri to Build RDF Schemas

1999
In this paper we present a new approach for building RDF schemas by integrating existing ontologies and structured vocabularies (thesauri). We will present a simple mechanism based on the specification of inclusion relationships between thesaurus terms and ontology concepts and show how these relationships can be exploited to create application ...

Schema-agnostic ranking of RDF properties

2015
In 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.
