Containment of Shape Expression Schemas for RDF [PDF]
Proceedings 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.

Deriving an Emergent Relational Schema from RDF Data [PDF]
Proceedings of the 24th International Conference on World Wide Web, 2015 We motivate and describe techniques that allow to detect an "emergent" relational schema from RDF data. We show that on a wide variety of datasets, the found structure explains well over 90% of the RDF triples. Further, we also describe technical solutions to the semantic challenge to give short names that humans find logical to these emergent tables ...

Building RDF-Schema Based Knowledge Map for Knowledge Management Systems [PDF]
Journal of Systemics, Cybernetics and Informatics, 2003 This paper attempts to implement the semantic web paradigm, which enables the semantic search of knowledge and information on the web environment, by adopting RDF, RDF-schema and Dublin core data element structure in the process of building knowledge map.

Answering SPARQL queries modulo RDF Schema with paths [PDF]
, 2013 SPARQL is the standard query language for RDF graphs. In its strict instantiation, it only offers querying according to the RDF semantics and would thus ignore the semantics of data expressed with respect to (RDF) schemas or (OWL) ontologies.

Novel Topic Maps to RDF/RDF Schema Translation Method
IEICE 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.

Benchmarking RDF Schemas for the Semantic Web [PDF]
, 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.

Scaling Up Schema Discovery for RDF Datasets [PDF]
2018 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 ...

A Novel Framework for RDF Schema Extraction in NoSQL Databases Using Sentence-BERT
IEEE AccessNoSQL databases, known for their flexibility and scalability, have become pivotal in handling diverse and unstructured data. However, their schema-less nature introduces significant challenges in metadata management, query optimization, and data ...
