Dataset Descriptions for Optimizing Federated Querying
نویسندگان
چکیده
Dataset description vocabularies focus on provenance, versioning, licensing, and similar metadata. VoID is a notable exception, providing some expressivity for describing subsets and their contents and can, to some extent, be used for discovering relevant resources and for optimizing querying. In this poster we describe an extension of VoID that provides the expressivity needed in order to support the query planning methods typically used in federated querying.

متن کاملQuerying the Web of Interlinked Datasets using VOID Descriptions
Query processing is an important way of accessing data on the Semantic Web. Today, the Semantic Web is characterized as a web of interlinked datasets, and thus querying the web can be seen as dataset integration on the web. Also, this dataset integration must be transparent from the data consumer as if she is querying the whole web. To decide which datasets should be selected and integrated for...
متن کاملLusail: A System for Querying Linked Data at Scale
The RDF data model allows publishing interlinked RDF datasets, where each dataset is independently maintained and is queryable via a SPARQL endpoint. Many applications would benefit from querying the resulting large, decentralized, geo-distributed graph through a federated SPARQL query processor. A crucial factor for good performance in federated query processing is pushing as much computation ...
متن کاملQuerying the Linked Data Graph using owl:sameAs Provenance
Querying the Linked Open Data cloud as a whole still remains problematic. Prior knowledge is required to federate the queries to the appropriate datasets: each dataset provides its own SPARQL endpoint to query that dataset, and each dataset uses its own vocabulary to describe their information. In this paper, we propose a federated and asynchronous SPARQL framework to query the global data spac...
متن کاملQuerying on Federated Sensor Networks
A Federated Sensor Network (FSN) is a network of geographically distributed Wireless Sensor Networks (WSNs) called islands. For querying on an FSN, we introduce the Layered Federated Sensor Network (L-FSN) Protocol. For layered management, L-FSN provides communication among islands by its inter-island querying protocol by which a query packet routing path is determined according to some path se...
