This book has its source in the question of whether anyknowledge engineering tools can be applied or analyzed incognition research and what insights and methods ofcognitive science might be relevant for knowledge engineers.It presents the proceedings of a workshop organized by theSpecial Interest Groups Cognition and Knowledge Engineeringof the German Society for Informatics, held in February 1992in Kaiserslautern.The book is structured into three parts. The first partcontrasts work in knowledge engineering with approaches fromthe side of the "soft sciences". The second part deals withcase-based approaches in expert systems. Cognition researchand the cognitive adequacy of expert systems are discussedin the third part. Contributions from Canada, England,France, Switzerland, and the USA demonstrate how knowledgeengineering and cognitive science are woven togetherinternationally.
