Operator-aware approach for boosting performance in RDF stream processing
Published on Nov 10, 20161274 Views
To enable efficiency in stream processing, the evaluation of a query is usually performed over bounded parts of (potentially) unbounded streams, i.e., processing windows “slide” over the streams. To a
