Substitution Garden and Polyethylene Terephthalate (PET) Plastic Waste as Refused Derived Fuel (RDF)
International Journal of Renewable Energy Development, 2022 The generation of polyethylene terephthalate (PET) plastic and garden waste must be recycled to support the circular economy. An alternative way to reduce the plastics waste is to reduce this waste by converting it into energy such as Refused Derived ...

RDF-to-Text Generation with Graph-augmented Structural Neural Encoders
International Joint Conference on Artificial Intelligence, 2020 The task of RDF-to-text generation is to generate a corresponding descriptive text given a set of RDF triples. Most of the previous approaches either cast this task as a sequence-to-sequence problem or employ graph-based encoder for modeling RDF triples ...

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 ...
