2nd International Workshop on Ordering and Reasoning

Organizing committee


More and more applications require real-time processing of massive, dynamically generated, ordered data; where order is often an essential factor reflecting recency, proximity or relevance. Stream and rank-aware data management techniques are progressively providing reactive and reliable query answering over such massive datasets, allowing integration of highly dynamic sources.

This workshop aims at bringing together the growing and very active community interested in integrating ordering with reasoning by using methods inspired by stream and rank-aware data management.

The final part of the workshop is dedicated to an open door meeting of the newly established W3C RDF Stream Processing Community Group.
