2nd International Workshop on Ordering and Reasoning (OrdRing2013)
October 21st/22nd, 2013 - Sydney, Australia

Collocated with the 12th International Semantic Web Conference (ISWC 2013)

Notification of acceptance: 9 August 2013


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. Key to their success
is the use of streaming algorithms that harness the natural or
enforceable orders in the data. The expressive power of Semantic
technologies is needed in those applications, but Semantic
Technologies risk being unable to address the needs of those
applications, because they do not consider ordering as an essential
property. Ranking results is often seen as an “added task”, performed
after inference, without affecting the inference process, which is

However, we perceive a trend towards order-aware semantic
technologies: both researchers and practitioners understand that order
matters in reasoning over massive and highly dynamic data. The idea of
Stream Reasoning is gaining considerable momentum. Some top-k query
answering techniques for Linked Data appeared. Several works are
considering SPARQL query answering on RDF annotated with labels
partially ordered. The Description Logic community is investigating
top-k ontological query answering.

This workshop aims at bringing together this growing and very active
community interested in integrating ordering with reasoning by using
methods inspired by stream and rank-aware data management. We see this
workshop as a first step to stimulate and guide a paradigm shift in
semantic technologies.

Topics include, but not limited to:

- Inferencing with streaming algorithms
- Ontological query answering over highly dynamic data
- Incremental maintenance of materialization of highly dynamic data
- Ontological top-k query answering over massive ordered data
- A top-k query answering for fuzzy logics
- Continuous query answering for fuzzy logics
- Knowledge Representation for ordered facts
- Applications of stream reasoning and top-k ontological query answering
- Role of parallelization and distribution in order-aware semantic technologies
- Harvesting and combining orders in data
- Approximation approaches to inference with orderings
- Proposals for and applications of benchmarks
- Implementation and evaluation experiences


We will welcome submissions describing ideas, experiments, and
application visions originating from requirements for, and efforts
aimed at, interleaving ordering and reasoning. We will encourage demos
and posters not exceeding 4 pages, short position papers not exceeding
6 pages as well as longer technical papers not exceeding 12 pages.
They should follow the LNCS proceedings style files.

Submissions should be formatted according to the Lecture Notes in
Computer Science guidelines for proceedings available at Papers
should be submitted in PDF format. All submissions will be done
electronically via the OrdRing2013 web submission system

The Workshop Proceedings will be published as CEUR Workshop
