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.

A Review of SHACL: From Data Validation to Schema Reasoning for RDF Graphs [PDF]
RW, 2021 We present an introduction and a review of the Shapes Constraint Language (SHACL), the W3C recommendation language for validating RDF data. A SHACL document describes a set of constraints on RDF nodes, and a graph is valid with respect to the document if

Assessing resolvability, parsability, and consistency of RDF resources: a use case in rare diseases [PDF]
Journal of Biomedical Semantics, 2023 Introduction Healthcare data and the knowledge gleaned from it play a key role in improving the health of current and future patients. These knowledge sources are regularly represented as ‘linked’ resources based on the Resource Description Framework ...

Rule Applicability on RDF Triplestore Schemas
, 2019 Rule-based systems play a critical role in health and safety, where policies created by experts are usually formalised as rules. When dealing with increasingly large and dynamic sources of data, as in the case of Internet of Things (IoT) applications, it becomes important not only to efficiently apply rules, but also to reason about their applicability

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 ...

Exploiting XML Schema for Interpreting XML Documents as RDF [PDF]
2008 IEEE International Conference on Services Computing, 2008 Interpreting legacy XML documents is a great challenge for realizing the vision of the semantic Web (SW). This paper presents an algorithm to transform XML data into RDF- foundation language of the SW - automatically. Our approach maps element definitions stored in XML schema to RDF schema ontology, where the ontology is used to describe the meaning ...

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 ...

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 ...

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.

Relational schema optimization for RDF-based knowledge graphs
Information Systems, 2021 Abstract Characteristic sets (CS) organize RDF triples based on the set of properties associated with their subject nodes. This concept was recently used in indexing techniques, as it can capture the implicit schema of RDF data. While most CS-based approaches yield significant improvements in space and query performance, they fail to perform well ...
