The RDF data model is a syntax-neutral way of representing RDF expressions. The data model representation is used to evaluate equivalence in meaning. Two RDF expressions are equivalent if and only if their data model representations are the same. This definition of equivalence permits some syntactic variation in expression without altering the ...
A popular graph model next to RDF is the labeled property graph, natively used by Neo4j. Different from RDF, LPGs can carry properties directly within their nodes and
The RMLMapper generates RDF graphs from SQL query results, W3C Web of Things [116] web APIs, SPARQL [92] query results, XLSX, ODS, CSV, TSV, JSON and XML …
Note that the seven lines in the N-Triples example correspond to the seven arcs in the diagram above. N-Triples is often used for exchanging large amounts of RDF and for processing large RDF graphs with line-oriented text processing tools. Turtle. Turtle [[RDF12-TURTLE]] is an extension of N-Triples. In addition to the basic N-Triples syntax ...
Large Language Model, Knowledge Graph Engineering, Large Language Model Benchmark 1. Introduction Large Language Models have gained significant attention in recent years, with GPT-4 being among the most prominent [1]. However, other models also demonstrate impressive perfor-mance in various tasks, as tracked in the LLMSYS Chatbot Arena ...
The object-class hierarchy of the network model is decomposed into numerous linked relational tables. Special query-building tools are then used to interact with the model using the exchange ...
The layered diagram with the form/colour coding shows how the model implements the FRBR semantic model (compare with Fig. 1) and the Music Ontology (compare with Fig. 2).
In the context of the Semantic Web, the Resource Description Framework (RDF), a language proposed by W3C, has been used for conceptual description, data modeling, and data querying.
Converts an RDF Turtle file to a readable diagram using PlantUML. Motivation. The best way to understand RDF data schemas (ontologies, application profiles, RDF shapes) is with a diagram. Many RDF visualization tools exist, but they have shortcomings, eg. Focus on large graphs, where the details are not easily visible
This paper aims to deliver a suitable RDF graph visualization for every level of users, because a node-link diagram can enhance the learning ability of users and the amount …

Resource Description Framework (RDF) is a standard data model of the Semantic Web, and it has been widely adopted in various domains in recent years for data and knowledge representation.
A couple of visually appealing additional alternatives, although IMHO they are not that well suited for visualizing extremely large RDF datasets: RDF Playground by Bastián Inostroza, Raúl Cid, Pablo Jaramillo, Rodrigo Iturrieta, Giuliano Celedón at the Univ. of Chile. RDF Sketch by Zazuko.

Various RDF data have been published in the Semantic Web. A key challenge for users to reuse these data is in understanding the large and unfamiliar RDF data, especially when the data schema is ...
The goal of this work is to provide an original (semi-automatic) annotation framework titled SVG-to-RDF whichconverts a collection of raw Scalable vector graphic (SVG) images into a searchable ...

RDF is a model to represent data about physical objects and abstract concepts. It''s a model to express relations between entities using a graph format. In the following sections, we''ll explain the RDF model in more detail, how to represent it, how to use it, and why. 2. Resource Description Framework (RDF) Representation

RDF-Q does NOT need vertexification or quadification: Note that in an RDF Quads-Only model (that contains quads only, no triples), if the "named graph" component of a quad is used as a name that represents the triple portion of the quad, neither vertexification nor quadification is relevant. Since RDF does not impose any restrictions on use of such names of …
To identify the best internal representation for an RDF dataset and a given SPARQL query, we decompose the query''s triple patterns into atomic operators and identify how they access a …
SHACL (Shape Constraint Language). SHACL is used for validating the RDF graphs against a set of conditions. RDF: It is the formal language for describing structured information. The primary goal of RDF is to exchange data on the web while preserving the original meaning of the data. It is a data model that is used to describe resources.
Definition 2 (RDF(S)): An RDF(S) model can be represented as a set of tuples (L, S), where: L is an identifier set, which specifically includes a class resource identifier set C, an attribute ...
RDF (Resource Description Framework) and RDF Schema (collectively called RDF(S)) are the normative language to describe the Web resource information.
High-quality phase diagram images and expert descriptions are collected from handbooks and then preprocessed to correct errors, remove redundancies, and enhance information.
The Weimar Jazz Database is a collection of manually transcribed and richly annotated jazz solos. It was produced as part of the Jazzomat Project at the University of Music "Franz Liszt" Weimar in Germany between 2012 and 2017 and has become an important corpus for systematic jazz research [14].The database comprises 456 instrumental jazz solos from 343 …
Identifying that the standard graph database model (essentially labelled graphs) is different from the triples-based RDF model, a triple-based model called Trial was introduced by Libkin et al., which combines the usual idea of triple stores used in many RDF implementations with that of graphs with data. Actually, one of the major problems encountered in modelling …
