5th Workshop on Dynamics of Knowledge and Belief (DKB-2015) and
4th Workshop KI & Kognition (KIK-2015):

Formal and Cognitive Reasoning
==============================

Organized by the "FG Wissensrepraesentation und Schliessen"
and the FG "Kognition" of the GI

Workshop at KI-2015
38th German Conference on Artificial Intelligence
September 21-25, 2015, Dresden, Germany

Aims and Scope
**************
Information for real life AI applications is usually pervaded by uncertainty and subject to change, and thus demands for non-classical reasoning approaches. At the same time, psychological findings indicate that human reasoning cannot be completely described by classical logical systems. Sources of explanations are incomplete knowledge, incorrect beliefs, or inconsistencies. Generally, people employ both inductive and deductive reasoning to arrive at beliefs; but the same argument that is inductively strong or powerful may be deductively invalid. Therefore, a wide range of reasoning mechanism has to be considered, such as analogical or defeasible reasoning. The field of knowledge representation and reasoning offers a rich palette of methods for uncertain reasoning both to describe human reasoning and to model AI approaches. Its many facets like qualitative vs. quantitative reasoning, argumentation and negotiation in multi-agent systems, causal reasoning for action and planning, as well as nonmonotonicity and belief revision, among many others, have become very active fields of research. Beyond computational aspects, these methods aim to reflect the rich variety of human reasoning in uncertain and dynamic environments.

The aim of this series of workshops is to address recent challenges and to present novel approaches to uncertain reasoning and belief change in their broad senses, and in particular provide a forum for research work linking different paradigms of reasoning. Previous events of the Workshop on "Dynamics of Knowledge and Belief" (DKB) took place in Osnabrueck (2007), Paderborn (2009), Berlin (2011), and Koblenz (2013). Previous editions of the Workshop on "KI & Kognition" (KIK) took place in Saarbruecken (2012), Koblenz (2013), and Stuttgart (2014).

This year, we put a special focus on papers from both fields that provide a base for connecting formal-logical models of knowledge representation and cognitive models of reasoning, addressing formal as well as experimental or heuristic issues. Reflecting this focus, the workshop "Formal and Cognitive Reasoning" at KI-2015 is organized jointly by the GI special interest groups "Wissensrepraesentation und Schliessen" and "Kognition".

We welcome papers on the following and any related topics:

- Action and change
- Agents and multiagent systems
- Analogical reasoning
- Argumentation theories
- Belief revision and belief update
- Cognitive modeling and empirical data
- Common sense and defeasible reasoning
- Decision theory and preferences
- Inductive reasoning and cognition
- Knowledge representation in theory and practice
- Learning and knowledge discovery in data
- Nonmonotonic and uncertain reasoning
- Ontologies and description logics
- Probabilistic approaches of reasoning

Publication
***********
The proceedings will be published as a technical report that will be available at the workshop. It is planned to publish a selection of extended papers after a post-workshop reviewing process in a special issue of an international journal.
