Scaling RDF with Time

Proceedings of the 17th international conference on World Wide Web, 2008
The World Wide Web Consortium's RDF standard primarily consists of (subject, property, object) triples that specify the value that a given subject has for a given property. However, it is frequently the case that even for a fixed subject and property, the value varies with time.

Compression of RDF dictionaries

Proceedings of the 27th Annual ACM Symposium on Applied Computing, 2012
The use of dictionaries is a common practice among those applications performing on huge RDF datasets. It allows long terms occurring in the RDF triples to be replaced by short IDs which reference them. This decision greatly compacts the dataset and thus mitigates its scalability issues. However, the dictionary size is not negligible and the techniques

Multidimensional RDF

2005
RDF has been proposed by W3C as a metadata model and language for representing information about resources in WWW. In this paper we introduce Multidimensional RDF (or MRDF), as an extension of RDF, suitable for representing context-dependent RDF data.

RDF Data Storage and Query Processing Schemes

ACM Computing Surveys, 2018
The Resource Description Framework (RDF) represents a main ingredient and data representation format for Linked Data and the Semantic Web. It supports a generic graph-based data model and data representation format for describing things, including their ...

Validating RDF Data

Validating RDF Data, 2017
RDF and Linked Data have broad applicability across many fields, from aircraft manufacturing to zoology. Requirements for detecting bad data differ across communities, fields, and tasks, but nearly all involve some form of data validation.

Pyrolysis and gasification studies of model refuse derived fuel (RDF) using thermogravimetric analysis

Fuel processing technology, 2018
Processing Municipal Solid Waste (MSW) into a Refuse Derived Fuel (RDF) reduces experimental variability and improves handling. This study analyzes the pyrolysis of individual components to define the model components that mimic real RDF.

Common Subsumbers in RDF

2013
Since their definition in 1992, Least Common Subsumers (LCSs) have been identified as services supporting learning by examples. Nowadays, the Web of Data offers a hypothetically unlimited dataset of interlinked and machine-understandable examples modeled as RDF resources.

The index organizations for RDF and RDF schema

2006 8th International Conference Advanced Communication Technology, 2006
In semantic Web, metadata and ontology for representing semantics and conceptual relationships of information resources are essential factors. RDF and RDF schema are the W3C standard models for describing metadata and ontology. Therefore, storing and querying RDF and RDF schema is one of major tasks in applications on the semantic Web.
