Harvesting RDF Triples [chapter]

Joe Futrelle
2006 Lecture Notes in Computer Science  
An RDF triple asserts a fact without attributing it to any actor or period of time, so the abstraction must be extended to support typical harvesting scenarios.  ...  RDF triples are a convenient abstraction for combining independentlygenerated factual statements, including statements about provenance[1].  ...  Harvesting Triples.  ...

Characterizing the Semantic Web on the Web [chapter]

Li Ding, Tim Finin
2006 Lecture Notes in Computer Science  
Using a corpus of more than 1.7 million documents comprising over 300 million RDF triples, we describe a number of global metrics, properties and usage patterns.  ...  To better understand this central use case, we have harvested and analyzed a collection of Semantic Web documents from an estimated ten million available on the Web.  ...  We measure an SWD's size as the number of triples in the SWD's RDF graph.  ...

Emergent Semantics: Towards Self-Organizing Scientific Metadata [chapter]

Bill Howe, Kuldeep Tanna, Paul Turner, David Maier
2004 Lecture Notes in Computer Science  
Data creators are responsible only for extracting data from heterogeneous sources according to a simple RDF-based data model. The system then loads the data into a generic RDBMS schema.  ...  the RDF triples, in a few hours.  ...  Two variants of the generic RDF schema appear in Figure 4a . A Triples table stores RDF triples in terms of string representations of the URIs.  ...

RDF Reasoning on Large Ontologies: A Study on Cultural Heritage and Wikidata [chapter]

Nuno Freire, Diogo Proença
2020 IFIP Advances in Information and Communication Technology  
The method defines two intermediate tasks that reduce the volume of data used during the execution of the RDF reasoner, resulting in an efficient execution taking on average 10.3 ± 7.6 ms per RDF resource  ...  RDF provides automation possibilities for semantic interpretation, which can lower the effort.  ...  We would like to acknowledge Antoine Isaac from the Europeana Foundation for his contribution to the preliminary discussion of our work regarding RDF reasoning and Wikidata.  ...

From RESTful Services to RDF: Connecting the Web and the Semantic Web [article]

Rosa Alarcon, Erik Wilde
2010 arXiv   pre-print
Building on this framework, a layered model of RESTful service semantics allows to represent a service's information in RDF/OWL.  ...  Based on the Resource Linking Language (ReLL), this paper describes a framework for how RESTful services can be described, and how these descriptions can then be used to harvest information from these  ...  RDF dataset in RDF triple stores, often exposing query interfaces in a RDF-oriented query language such as SPARQL [26] .  ...

CMD2RDF: Building a Bridge from CLARIN to Linked Open Data [chapter]

2017 CLARIN in the Low Countries  
However, the Resource Description Format (RDF) as used by Linked Open Data (LOD) is gaining more popularity.  ...  RDF has interesting potential for queries that involve both metadata about and the content of linguistic resources.  ...  Acknowledgements The authors would like to thank Matej Durco for the initial work on the mapping from CMD to RDF, which formed the foundation for the CLARIN-NL CMD2RDF project in which we were able to  ...

Extending DCAM for Metadata Provenance

Kai Eckert, Daniel Garijo, Michael Panzer
2011 International Conference on Dublin Core and Metadata Applications  
Consequently, descriptions would be defined in RDF only implicitly as triples describing the same resource.  ...  In RDF however, even a known individual triple may be part of several graphs (e.g., description sets), only some of which might have been annotated.  ...

The European Data Portal: Scalable Harvesting and Management of Linked Open Data

Fabian Kirstein, Simon Dutkowski, Benjamin Dittwald, Manfred Hauswirth
2019 International Semantic Web Conference  
The European Data Portal fosters the adoption and distribution of Linked Open Data by offering more than 130 million RDF triples.  ...  To address this problem, we designed and implemented a novel platform for harvesting and managing native DCAT-APcompliant RDF.  ...  It receives data from the Harvester, preprocesses it and stores the RDF in the triplestore.  ...

Refactoring HUBzero for linked data

Michael Witt, Yongyang Yu
2012 Proceedings of the 12th ACM/IEEE-CS joint conference on Digital Libraries - JCDL '12  
Resource Maps can be harvested using an RDF crawler or an Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) data provider that were bundled for demonstration purposes.  ...  The crawler traverses URIs to all the RDF triples and stores them in an N-Triples file. N-Triples is a line-based, plain text serialization format for RDF graphs.  ...  After all the triples have been harvested from the example hub, the N-Triples file is flushed to a TDB triplestore for permanent storage and retrieval within a Jena framework 4 .  ...
