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, 2013 and 2014) 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 spatial 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
