Mapping RDF Databases to Property Graph Databases
IEEE Access, 2020 RDF triplestores and property graph databases are two approaches for data management which are based on modeling, storing and querying graph-like data. In spite of such common principle, they present special features that complicate the task of database ...

Parameters Affecting RDF-Based Pellet Quality
Energies, 2020 Increasing production of waste has compelled the development of modern technologies for waste management. Certain fractions of municipal solid wastes are not suitable for recycling and must be utilised in other ways. Materials such as refuse-derived fuel

RDF2Vec: RDF graph embeddings and their applications
Semantic Web, 2019 Linked Open Data has been recognized as a valuable source for background information in many data mining and information retrieval tasks. However, most of the existing tools require features in propositional form, i.e., a vector of nominal or numerical ...

The WebNLG Challenge: Generating Text from RDF Data
International Conference on Natural Language Generation, 2017 The WebNLG challenge consists in mapping sets of RDF triples to text. It provides a common benchmark on which to train, evaluate and compare “microplanners”, i.e.

QAnswer KG: Designing a Portable Question Answering System over RDF Data
Extended Semantic Web Conference, 2020 While RDF was designed to make data easily readable by machines, it does not make data easily usable by end-users. Question Answering (QA) over Knowledge Graphs (KGs) is seen as the technology which is able to bridge this gap.

Mobilizable RDF/d-RDF burning program [PDF]
, 1982 The Mobilizable RDF/d-RDF Burning Program was conceived to promote the utilization of refuse-derived fuels (RDF) as a supplement to existing fossil fuel sources in industrial-sized boilers. The program explores the design, development, and eventual construction of densified-RDF (d-RDF) for use in boiler combustion testing as a supplement to stoker coal

Potential Utilization of RDF as an Alternative Fuel to be Used in Cement Industry in Jordan
Sustainability, 2019 This experimental research aimed to examine potential production and utilization of RDF derived from mixed municipal solid waste using bio-drying technology to be used as a substitute fuel for the traditional fuel currently used in cement plants in ...

Estimating the Cardinality of Conjunctive Queries over RDF Data Using Graph Summarisation [PDF]
The Web Conference, 2018 Estimating the cardinality (i.e., the number of answers) of conjunctive queries is particularly difficult in RDF systems: queries over RDF data are navigational and thus tend to involve many joins.

The VLDB Journal, 2014 The Resource Description Framework (RDF) pioneered by the W3C is increasingly being adopted to model data in a variety of scenarios, in particular data to be published or exchanged on the Web. Managing large volumes of RDF data is challenging, due to the sheer size, the heterogeneity, and the further complexity brought by RDF reasoning.

Extended Semantic Web Conference, 2019 We discuss Shape Expressions (ShEx), a concise, formal, modeling and validation language for RDF structures. For instance, a Shape Expression could prescribe that subjects in a given RDF graph that fall into the shape “Paper” are expected to have a ...
