-- Description of the workshop --

Dealing with context is one of the most interesting and most important
problems faced in Artificial Intelligence (AI). Traditional AI applications
often require to model, store, retrieve and reason about knowledge that
holds within certain circumstances - the context. Without considering this
contextual information, reasoning can easily run to problems such as:
inconsistency, when considering knowledge in the
wrong context; inefficiency, by considering knowledge irrelevant for a
certain context; incompleteness, since an inference may depend on knowledge
assumed in the context and not explicitly stated. Contextual information is
also relevant in many tasks in knowledge representation and reasoning such
as common-sense reasoning, dealing with inconsistency, ambiguity, and
uncertainty, evolution, etc.

In recent years, research in contextual knowledge representation and
reasoning became more relevant in the areas of Semantic Web, Linked Open
Data, and Ambient Intelligence, where knowledge is not considered a
monolithic and static asset, but it is distributed in a network of
interconnected heterogeneous and evolving knowledge resources. The ARCOE
workshop aims to provide a dedicated forum for researchers interested in
these topics to discuss recent developments, important open issues, and
future directions.

-- Topics --

ARCOE-12 welcomes submissions on the topics below as well as on their
intersection and other topics related to acquisition, representation,
reasoning with context and its applications.

Philosophical and theoretical foundations of context:

1. What is context and how should it be represented.
2. Relevant types of contextual information and their properties.
3. Combining contextual information with object information for reasoning.
4. Context and common-sense reasoning.
5. Exploiting context in inconsistency and uncertainty handling,
defeasible reasoning and argumentation.
6. Contextual logic programming.
7. Updating contextual knowledge and context-aware belief revision.
8. Frameworks for formalizing context and context-aware knowledge
representation.

Context modeling and contextual knowledge engineering:

1. Modeling of user's/agent's context.
2. Context driven organization of knowledge and modeling.
3. Ontologies for context modeling.
4. Context-aware modeling tools and methodology.
5. Comparisons to context-unaware modeling techniques.

Effective reasoning with context:

1. Effective context-aware reasoning algorithms.
2. Distributed reasoning with context.
3. Context-driven heuristics in classical reasoning systems.
4. Reasoning under uncertainty and inconsitency.
5. Defeasible reasoning.
4. Hybrid formalisms for reasoning with context, including sub-symbolic
contexts

Applications of context in areas such as:

1. Agent communication and coordination.
2. Semantic Web and Linked Open Data.
3. Knowledge modularization.
4. Ontology matching.
5. Ontology fault diagnosis and repair.
6. Ontology evolution and versioning.
7. Information integration.
8. Ambient intelligence and pervasive computing.
9. Exploiting context in Web 2.0 applications, e-commerce, and e-learning.

-- Submission Requirements --

Papers of two types can be submitted. Regular papers are intended for
research
reports and surveys. ARCOE also welcomes reports on significant work in
progress which has already achieved some interesting partial results, as well
as papers recently submitted or published elsewhere as long as their topic is
in line with the workshop. Regular papers should not exceed 12 pages in
length
including references. Position papers are intended for presentation of
interesting new open issues and challenges, and opinions on the status of the
field. Position papers are limited to 6 pages including references. All
papers
must be formatted using the Springer LNCS style:

http://www.springer.com/comp/lncs/Authors.html

and submitted in PDF format via EasyChair using:

https://www.easychair.org/conferences/?conf=arcoe12

The distinction during the selection-phase will be based on

1) Relevance, significance and quality of the submission;

2) The contribution's potential to foster cross-pollination and
discussions on ARCOE main themes during the event.

Accepted papers will be presented either as oral presentations or as
posters, depending on the choice of the program committee.
However, all accepted papers will be included in the Working Notes
in their full form and will be accessible via the Internet.
