***********************************************************************

Knowledge representation encompasses a variety of methods and
formalisms to encode and process all types of knowledge, belief,
and information. It provides the theoretical foundation for rational and intelligent behaviour in real environments, focusing on topics
like default logics and uncertain reasoning, belief change, ontologies,
and argumentation, among many others. Moreover, in a thematical
respect, knowledge representation is closely related to the areas of
machine learning and knowledge discovery the methods of which allow
the acquisition of useful information to build up knowledge bases.

Knowledge representation has made substantial progress over the last
decade by devising sophisticated methods for inference and reasoning.
Nevertheless, the connection to learning still holds undeveloped
potential in methodological and technical respects which might be
crucial for practical applications. Furthermore, the handling of
relational information, i.e. the explicit representation of knowledge
about objects and its linking to knowledge about classes, is still a
challenge for many subareas of knowledge representation. Ontologies,
logic programming and probabilistic relational models are just some
important examples of areas of research that address both of these
points.

The aim of this workshop is to strengthen the connection between
knowledge representation and learning by focusing on relational and
first-order approaches to all areas of knowledge representation and
learning, in particular

* default and conditional logics
* logic programming
* uncertain reasoning
* nonmonotonic and nonclassical logics
* belief revision
* probabilistic networks
* inference processes
* machine learning
* data mining
* knowledge discovery
* knowledge engineering
* ontologies
* agent systems
* applications
