Knowledge Representation and Reasoning (KR&R) is a vibrant and exciting field
of human endeavour. KR&R techniques are key drivers of innovation in computer
science, and they have led to significant advances in practical applications in a
wide range of areas from Artificial Intelligence to Software Engineering.


Explicit representations of knowledge manipulated by reasoning engines are an
integral and crucial component of intelligent systems. Semantic Web technologies,
the design of software agents and Bio-Informatics technologies, in particular, provide
significant challenges for KR&R.


We intend KR2008 to be a forum for the exchange of new ideas, issues, and results
among the community of researchers in the principles and practices of KR&R
systems. We encourage papers presenting substantial new results in the principles
of KR&R systems that clearly contribute to the formal foundations or show the
applicability of the results to implemented or implementable systems. We also
encourage ``reports from the field
