Querying RDF streams with C-SPARQL
Continuous SPARQL (C-SPARQL) is a new language for continuous queries over streams of RDF data. CSPARQL queries consider windows, i.e., the most recent triples of such streams, ob...

Using Stream Semantics for Continuous Queries in Media Stream Processors
In this demonstration paper we present a stream query processor capable of handling media (audio, video, motion ...) and feature streams. We show that due to their inherent semant...

Tight Lower Bounds for Query Processing on Streaming and External Memory Data
We study a clean machine model for external memory and stream processing. We show that the number of scans of the external data induces a strict hierarchy (as long as work space is...

Answering queries over incomplete data stream histories
Streams of data often originate from many distributed sources. A distributed stream processing system publishes such streams of data and enables queries over the streams. This allo...
