CALL FOR PARTICIPATION: Automated Reasoning about Context and Ontology Evolution, 18 July 2011, SPAIN

ARCOE-11 at IJCAI-11 -Barcelona, Spain

-- Description of the workshop --

Methods of automated reasoning have solved a large number of problems in Computer Science by using 
formal ontologies expressed in logic-based languages. Over the years, though, each problem or class
of problems has required a different ontology, and sometimes a different version of logic. Moreover,
the processes of designing, controlling and maintaining an ontology as well as its different 
versions have turned out to be inherently complex. All this has motivated much investigation in a 
wide range of disparate disciplines -- from logic-based Knowledge Representation and Reasoning to 
Software Engineering, from Databases to Multimedia -- about how to relate ontologies to one another.

ARCOE-11 aims at bringing together researchers and practitioners from core areas of Artificial 
Intelligence (Knowledge Representation and Reasoning, Contexts, and Ontologies) and related 
disciplines to discuss these kinds of problems and relevant results. Historically, there have been 
at least three different, yet interdependent motivations behind this type of research: defining 
the relationship between an ontology and its context; providing support to ontology engineers; 
enhancing problem solving and communication for software agents.

Ontology and Context.  Most application areas have recognised the need for representing and 
reasoning about knowledge that is distributed over many resources. Such knowledge, as well as 
its intrinsic relevance and usability, depends on its context. The latter is determined by the 
syntactic and/or semantic structure of the resources, the scope of the underlying language, 
among other things. Research on information integration, distributed knowledge management, the 
semantic web, multi-agent and distributed reasoning have pinned down different aspects of how 
ontologies relate to and/or develop within their context.

Ontology Engineering.  Ontology engineers are not supposed to succeed right from the beginning 
when (individually or collaboratively) developing and maintaining an ontology. Despite their 
expertise and any assistance from domain experts, revision cycles are the rule. Moreover quite 
often different ontologies have to be integrated in such a way for them to be operable together 
(merging). Research on the automation of the process of engineering an ontology has improved 
efficiency and reduced the introduction of unintended meanings by means of interactive ontology 
editors that provide support for ontology change (debugging, updates and repair), maintenance 
(versioning) and integration (merging). Moreover, ontology matching has studied the process of 
manual, off-line alignment of two or more known ontologies.

Problem Solving and Communication for Agents.  Agents that communicate with one another without 
having full access to their respective ontologies or that are programmed to face new 
non-classifiable situations must change their own ontology dynamically at run-time -- they cannot 
rely solely on human intervention. Research on this problem has either concentrated on techniques 
borrowed from the non-monotonic reasoning and belief revision communities or on changes of 
signature, i.e., of the grammar of the ontology's language, with a minimal disruption to the
original theory. This is also an important issue in the emerging area of General Game Playing.

ARCOE-11 will provide a multi-disciplinary forum, where differences in methodologies, 
representation languages and techniques are over-arched and hopefully overcome. Accordingly, 
the workshop will be structured into four tracks: three of them will focus on specific areas, the 
fourth one will foster links and integration.

Track 1:  Context and Ontology
This track will consist of presentations and discussions around the theme of Context and Ontology, 
a well-established research area that has mainly concentrated on the relationship between contexts 
and ontologies for distributed information and for the enhancement of software agents.

Track 2:  Common Sense and Non-Monotonic Reasoning for Ontologies This track will consist of 
presentations and discussions around the theme of Common Sense and Non-Monotonic Reasoning in 
logic-based Knowledge Representation and Reasoning for ontologies. These are classic areas of AI, 
which since their origins have produced remarkable results on logic-based methods for supporting 
knowledge engineers and for enhancing software agents.

Track 3:  Automated Ontology Evolution
This track will consist of presentations and discussions around the theme of Automated Ontology 
Evolution for agents and general problem solving, an area which in recent years has been drawing 
the attention of Artificial Intelligence and Knowledge Representation and Reasoning on the 
assessment of change impact and the automation of ontology evolution.

Track 4: Links and integration
This track will foster links and integration by means of invited talks and (panel) discussions. 
Topics that are likely to be covered are: the formalisation of software engineering concepts for 
ontology development; the relationship between automated reasoning and information retrieval; 
relationships between representation languages; relationships between canonical domains; 
relationships between contexts and ontology evolution and between non-monotonic reasoning and 
ontology evolution.

ARCOE-11 will bring the participants to position the various approaches with respect to one another.
Hopefully, though, the workshop will also start a process of cross-pollination and set out the 
constitution of a truly interdisciplinary research community dedicated to automated reasoning about
contexts and ontology evolution.

-- Special Issue on ARCOE-related Themes --

There has recently been an agreement with the Journal of Web Semantics for a Special Issue on 
Reasoning with context in the Semantic Web. The Call for Papers is open to anyone and it certainly 
is an opportunity to submit for publication quality work about ARCOE-like themes.

The special issue aims at bringing together work on reasoning with context in the Semantic Web as 
seen from various perspectives, e.g., ontology integration, ontology development, ontology 
evolution etc. Submitted articles, which may describe either theoretical results or applications, 
must clearly pertain to the Semantic Web and/or to semantic technologies. They should present 
either Semantic Web specific approaches to reasoning with context, or approaches that have 
characteristics that are interesting for the Semantic Web (e.g., scalability, bounded reasoning), 
or approaches that are of value to a larger community containing a non-trivial Semantic Web 
sub-community (e.g. revision/update techniques and error pin-pointing).
