The SPHN Schema Forge – transform healthcare semantics from human-readable to machine-readable by leveraging semantic web technologies [PDF]
Journal of Biomedical SemanticsBackground The Swiss Personalized Health Network (SPHN) adopted the Resource Description Framework (RDF), a core component of the Semantic Web technology stack, for the formal encoding and exchange of healthcare data in a medical knowledge graph.

Semantics and Validation of Shapes Schemas for RDF [PDF]
, 2017 We present a formal semantics and proof of soundness for shapes schemas, an expressive schema language for RDF graphs that is the foundation of Shape Expressions Language 2.0.

TRANSFORMATION FROM SEMANTIC DATA MODEL TO RDF [PDF]
JUTI: 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.

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.

Updates to the dblp RDF schema
, 2022 In the six months since the release of the dblp RDF dump and its persistent snapshot releases, the RDF dump has been downloaded a total of about a thousand times. We are pleased to see that the community is interested in using our semantic data in their research and beyond.

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 ...

Inference of Shape Expression Schemas Typed RDF Graphs [PDF]
, 2021 We consider the problem of constructing a Shape Expression Schema (ShEx) that describes the structure of a given input RDF graph. We employ the framework of grammatical inference, where the objective is to find an inference algorithm that is both sound i.e., always producing a schema that validates the input RDF graph, and complete i.e., able to ...

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.

Sorted Neighborhood for Schema-Free RDF Data [PDF]
, 2015 Entity Resolution ER concerns identifying pairs of entities that refer to the same underlying entity. To avoid $$On^2$$ pairwise comparison of n entities, blocking methods are used. Sorted Neighborhood is an established blocking method for Relational Databases.
