The index organizations for RDF and RDF schema

2006 8th International Conference Advanced Communication Technology, 2006
In 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. Therefore, storing and querying RDF and RDF schema is one of major tasks in applications on the semantic Web.

The path index for query processing on RDF and RDF schema

The 7th International Conference on Advanced Communication Technology, 2005, ICACT 2005., 2005
In the semantic Web, metadata and ontology plays important roles for advanced information retrieval systems. A large amount of RDF documents for describing metadata and RDF Schema documents for representing ontology is made available. Therefore, many studies to store and query metadata and ontology in RDF and RDF Schema are required.

Scalable Schema Discovery for RDF Data

2020
The semantic web provides access to an increasing number of linked datasets expressed in RDF. One feature of these datasets is that they are not constrained by a schema. Such schema could be very useful as it helps users understand the structure of the entities and can ease the exploitation of the dataset.

RDF Schema and Semantics

2020
This chapter presents an in-depth primer for the RDF Schema (RDFS 1.1) standard, which is primarily used to define a lightweight semantics for the classes and properties used in RDF graphs. After an initial motivation and overview, we discuss the RDFS vocabulary, and how it can be used to define sub-classes, sub-properties, domain and ranges, amongst ...

Superimposed multidimensional schemas for RDF data analysis

2017 IEEE 14th International Scientific Conference on Informatics, 2017
Traditional data analysis employs online analytical processing (OLAP) systems operating on multidimensional (MD) data. The Resource Description Framework (RDF) serves as the foundation for the publication of a growing amount of semantic web data still largely untapped by data analysis.

Schema Discovery in RDF Data Sources

2015
The Web has become a huge information space consisting of interlinked datasets, enabling the design of new applications. The meaningful usage of these datasets is a challenge, as it requires some knowledge about their content such as their types and properties. In this paper, we present an automatic approach for schema discovery in RDF(S)/OWL datasets.
