A Unified Interface for Optimizing Continuous Query in Heterogeneous RDF Stream Processing Systems
نویسندگان
چکیده
The W3C RDF Stream Processing (RSP) community has proposed a common model and a language for querying RDF streams. However, the current RSP systems significantly differ from each other in terms of performance. In this paper, we propose a unified interface for optimizing a continuous query in heterogeneous RSP systems. To enhance the performance of RSP, a unified interface decomposes a query, reassembles partial queries and assigns them to appropriate RSP systems. Experimental results show that the proposed approach performs better in terms of memory consumption and latency.

Towards a Unified Language for RDF Stream Query Processing
In recent years, several RDF Stream Processing (RSP) systems have emerged, which allow querying RDF streams using extensions of SPARQL that include operators to take into account the velocity of this data. These systems are heterogeneous in terms of syntax, capabilities and evaluation semantics. Recently, the W3C RSP Group started to work on a common model for representing and querying RDF stre...
متن کاملIntegrating Semantic Knowledge in Data Stream Processing
Complex Event Processing (CEP) has been established as a well-suited software technology for processing high-frequent data streams. However, intelligent stream based systems must integrate stream data with semantical background knowledge. In this work, we investigate different approaches on integrating stream data and semantic domain knowledge. In particular, we discuss from a software engineer...
متن کاملSLD Revolution: A Cheaper, Faster yet more Accurate Streaming Linked Data Framework
RDF Stream Processing (RSP) is gaining momentum. The RDF stream data model is progressively adopted and many SPARQL extensions for continuous querying are converging into a unified RSP query language. However, the RSP community still has to investigate when transforming data streams in RDF streams pays off. In this paper, we report on several experiments on a revolutionized version of our Strea...
متن کاملQuery Rewriting in RDF Stream Processing
Querying and reasoning over RDF streams are two increasingly relevant areas in the broader scope of processing structured data on the Web. While RDF Stream Processing (RSP) has focused so far on extending SPARQL for continuous query and event processing, stream reasoning has concentrated on ontology evolution and incremental materialization. In this paper we propose a different approach for que...
متن کاملAn Adaptive Framework for RDF Stream Processing
In this paper, we propose a novel framework for RDF stream processing named PRSP. Within this framework, the evaluation of C-SPARQL queries on RDF streams can be reduced to the evaluation of SPARQL queries on RDF graphs. We prove that the reduction is sound and complete. With PRSP, we implement several engines to support C-SPARQL queries by employing current SPARQL query engines such as Jena, g...
