ABSTRACT
C-SPARQL is an extension of SPARQL to support continuous queries, registered and continuously executed over RDF data streams, considering windows of such streams. Supporting streams in RDF format guarantees interoperability and opens up important applications, in which reasoners can deal with knowledge that evolves over time. We present C-SPARQL by means of examples in Urban Computing.

A SPARQL Engine for Streaming RDF Data
SITIS '07: Proceedings of the 2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based SystemThe basic data format of the Semantic Web isRDF. SPARQL, which has been developed by the W3C, is the upcoming standard for RDF query languages. Typical engines for processing SPARQL queries on RDF data first read all RDF data, may build indices of the ...
RDF, Jena, SparQL and the 'Semantic Web'
SIGUCCS '09: Proceedings of the 37th annual ACM SIGUCCS fall conference: communication and collaborationThe Resource Description Format (RDF) is used to represent information modeled as a "graph": a set of individual objects, along with a set of connections among those objects. In that role, RDF is one of the pillars of the so-called Semantic Web. This ...
Using SPARQL to query bioportal ontologies and metadata
ISWC'12: Proceedings of the 11th international conference on The Semantic Web - Volume Part IIBioPortal is a repository of biomedical ontologies--the largest such repository, with more than 300 ontologies to date. This set includes ontologies that were developed in OWL, OBO and other languages, as well as a large number of medical terminologies ...
