GOALS AND TOPICS
----------------

More and more applications require real-time processing of large, dynamically generated, ordered data, where order captures essential information about recency, proximity or relevance. Recency is crucial for recognizing temporal events, as in complex event processing; proximity and relevance are essential for ranking query answers, as in top-k query answering. In some cases, orders are a natural, even unavoidable, aspect of the data, which may constrain the ways in which we can access it. In other cases, orders need to be derived by additional computations, and then be enforced on the (unordered) input. While each of these scenarios represents some unique challenges, all of them involve streams of data and require us to reason about sequences of events. The goal of this workshop is to explore this joint concept of ordered data processing.

Semantic technologies can play a relevant role in this setting, as they provide the expressive power to integrate highly dynamic sources. This is also witnessed by a number of recent works on order-related concepts, such as Stream Reasoning and top-k ontological query answering. Stream and rank-aware data management techniques are progressively providing reactive and reliable query answering over massive datasets, while ontological process models allow us to define meaningful patterns in event streams. Related works range from applied topics, such as query optimization, to foundational topics, such as temporal logics.

This workshop (as its predecessors in 2011 and 2013) 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. It thus aims to stimulate and guide a paradigm shift in semantic technologies.

Topics include, but are not limited to:

- Streaming algorithms in query answering and reasoning
- Ontology-based data access over data streams
- Modelling complex events, processes, and patterns in ordered data
- Incremental maintenance of materialization of data streams
- Continuous query answering
- Ontological top-k query answering
- Continuous and top-k query answering for fuzzy and probabilistic logics
- Order in knowledge representation, such as temporal or spacial orders
- Topologies for distributed processing of data streams
- Data compression algorithms for data stream processing
- Parallelization and distribution in order-aware semantic technologies
- Approximation approaches to inference with orderings
- APIs for data stream exchange
- Proposals for and applications of benchmarks
- Applications of stream reasoning and top-k ontological query answering
- Implementation and evaluation experiences

SUBMISSION GUIDELINES AND PROCEEDINGS
-------------------------------------

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 short position and short demo 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 http://www.springer.com/computer/lncs?SGWID=0-164-7-72376-0. Papers should be submitted in PDF format. All submissions will be done electronically via the OrdRing2014 web submission system (http://www.easychair.org/conferences/?conf=ordring2014).

At least one author of each accepted paper must register for the workshop. Information about registration will appear soon on the ISWC 2014 Web page.

The Workshop Proceedings will be published as CEUR Workshop Proceedings (www.ceur-ws.org)
