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 of Interest

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:

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

Context modeling and contextual knowledge engineering:

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

Effective reasoning with context:

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

Applications of context in areas such as:

- Agent communication and coordination.
- Semantic Web and Linked Open Data.
- Knowledge modularization.
- Ontology matching.
- Ontology fault diagnosis and repair.
- Ontology evolution and versioning.
- Information integration.
- Ambient intelligence and pervasive computing.
- Exploiting context in Web 2.0 applications, e-commerce, and e-learning.

Submission and attendance

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:

and submitted in PDF format via EasyChair using:

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.


Registration will open on June 12. All attendanees need to register for ECAI-12 as well as for the ARCOE-12 worshop. Registration information is now available via ECAI-12 web site.
