Der Band enthält alle Beiträge, die für die 12. Jahrestagung 'Künstliche Intelligenz' (GWAI-88) vom Programmkomitee akzeptiert worden sind. Die 29 Fachbeiträge werden von drei eingeladenen Hauptvorträgen ergänzt: B. Bartsch-Spörl untersucht den augenblicklichen Entwicklungsstand von KI-Systemen, die in der Praxis eingesetzt werden, und zeigt Perspektiven für die zukünftige Entwicklung auf; J. Funke geht auf den methodologischen Unterschied zwischen Kognitionswissenschaften und KI-Forschung ein; P. Levi stellt neue Planungsverfahren für mehrere autonome Agenten als Teilgebiete der Robotik dar. Die Fachbeiträge sind in erster Linie den Teilgebieten Wissensrepräsentation und Natürlichsprachliche Systeme zuzuordnen, zwei Bereiche, auf denen in der Bundesrepublik traditionell intensiv geforscht wird. Vier Beiträge stellen neue Methoden aus dem Feld der niederen Bilddeutung vor. Neben diesen Schwerpunkten enthält der Band auch Arbeiten aus den Gebieten Maschinelles Lernen, Kognition, Deduktion und KI-Programmierung. In einer Zeit, in der die KI-Forschung in der Bundesrepublik einen enormen Aufschwung erlebt, ist gerade auch eine kritische Einschätzung der Forschungssituation wünschenswert. Die letzten vier Beiträge des Bandes sind deshalb Positionspapiere zum Thema 'Grenzen der KI', die während einer Podiumsdiskussion auf der GWAI-88 diskutiert wurden. Die Hälfte der Beiträge dieses Bandes ist deutsch, die andere Hälfte englisch abgefaßt.

ICICS 2001, the Third International Conference on Information and Commu- cations Security, was held in Xi’an, China, 13-16 November 2001. Among the preceding conferences, ICICS’97 was held in Beijing, China, 11-14 November 1997 and ICICS’99 in Sydney, Australia, 9-11 November 1999. The ICICS’97 and ICICS’99 proceedings were released as volumes 1334 and 1726 of Springer- Verlag’s Lecture Notes in Computer Science series. ICICS 2001 was sponsored by the Chinese Academy of Sciences (CAS), the - tional Natural Science Foundation of China, and the China Computer Fe- ration. The conference was organized by the Engineering Research Center for Information Security Technology of the Chinese Academy of Sciences (ERCIST, CAS) in co-operation with the International Association for Cryptologic Re- arch (IACR), the International Communications and Information Security - sociation (ICISA), and the Asiacrypt Steering Committee. The format of ICICS 2001 was selected to cover the complete spectrum of - formation and communications security, and to promote participant interaction. The sessions were designed to promote interaction between the major topics of the conference: theoretical foundations of security, secret sharing, network - curity, authentication and identi?cation, boolean functions and stream ciphers, security evaluation, signatures, block ciphers and public-key systems, infor- tion hiding, protocols and their analysis, and cryptanalysis. The 29-member Program Committee considered 134 submissions from 23 di- rent countries and regions, among them 56 papers were accepted for presentation.

The present volume contains edited versions of the communications presented at an International Workshop on "Expert Systems in Production Engineering", held in Spa, Belgium, in 1986. Introductory papers on Artificial Intelligence and Expert Systems are complemented by case studies of Expert Systems in practice, primarily, in the area of Mechanical Engineering and discussions of the possibilities and the limitations of Expert Systems.

Second Generation Expert Systems have been a very active field of research during the last years. Much work has been carried out to overcome drawbacks of first generation expert systems. This book presents an overview and new contributions from people who have played a major role in this evolution. It is divided in several sections that cover the main topics of the subject: - Combining Multiple Reasoning Paradigms - Knowledge Level Modelling - Knowledge Acquisition in Second Generation Expert Systems - Explanation of Reasoning - Architectures for Second Generation Expert Systems. This book can serve as a reference book for researchers and students and will also be an invaluable help for practitioners involved in KBS developments.

In an attempt to address the theoretical gap between linguistics and philosophy, a group of semanticists, calling itself the Generic Group, has worked to develop a common view of genericity. Their research has resulted in this book, which consists of a substantive introduction and eleven original articles on important aspects of the interpretation of generic expressions. The introduction provides a clear overview of the issues and synthesizes the major analytical approaches to them. Taken together, the papers that follow reflect the current state of the art in the semantics of generics, and afford insight into various generic phenomena.
