Benchmarking RDF Schemas for the Semantic Web [PDF]

open access: bronze, 2002
Describing web resources using formal knowledge (i.e., creating metadata according to a formal representation of a domain of discourse) is the essence of the next evolution step of the Web, termed the Semantic Web. The W3C's RDF/S (Resource Description Framework/Schema Language) enables the creation and exchange of resource metadata as normal web data.

TRANSFORMATION FROM SEMANTIC DATA MODEL TO RDF [PDF]

open access: yesJUTI: Jurnal Ilmiah Teknologi Informasi, 2004
There have been several efforts to use relational model and database to store and manipulate Resource Description Framework (RDF). They have one general disadvantage, i.e.

Sesame: A Generic Architecture for Storing and Querying RDF and RDF Schema [PDF]

open access: bronze, 2002
RDF and RDF Schema are two W3C standards aimed at enriching the Web with machine-processable semantic data. We have developed Sesame, an architecture for efficient storage and expressive querying of large quantities of metadata in RDF and RDF Schema. Sesame's design and implementation are independent from any specific storage device.

Containment of Shape Expression Schemas for RDF [PDF]

open access: greenProceedings of the 38th ACM SIGMOD-SIGACT-SIGAI Symposium on Principles of Database Systems, 2019
We study the problem of containment for shape expression schemas (ShEx) for RDF graphs. We identify a subclass of ShEx that has a natural graphical representation in the form of shape graphs and their semantics is captured with a tractable notion of embedding of an RDF graph in a shape graph.

Novel Topic Maps to RDF/RDF Schema Translation Method

open access: bronzeIEICE Transactions on Information and Systems, 2008
We propose an enhanced method for translating Topic Maps to RDF/RDF Schema, to realize the Semantic Web. A critical issue for the Semantic Web is to efficiently and precisely describe Web information resources, i.e., Web metadata. Two representative standards, Topic Maps and RDF have been used for Web metadata.

Integrating ontologies and thesauri for RDF schema creation and metadata querying [PDF]

open access: greenInternational Journal on Digital Libraries, 2000
In this paper we present a new approach for building metadata schemas by integrating existing ontologies and structured vocabularies (thesauri). This integration is based on the specification of inclusion relationships between thesaurus terms and ontology concepts and results in application-specific metadata schemas incorporating the structural views ...

Scaling Up Schema Discovery for RDF Datasets [PDF]

open access: green2018 IEEE 34th International Conference on Data Engineering Workshops (ICDEW), 2018
An increasing number of data sources is published on the Web, expressed using the languages proposed by the W3C such as RDF. In these sources, data is not constrained by a schema: data could differ from the schema-related statements provided in the source; furthermore, the schema could be incomplete of even missing; this makes the use of the data ...

Shape Expressions Schemas [PDF]

open access: yesarXiv, 2015
We present Shape Expressions (ShEx), an expressive schema language for RDF designed to provide a high-level, user friendly syntax with intuitive semantics. ShEx allows to describe the vocabulary and the structure of an RDF graph, and to constrain the allowed values for the properties of a node.
