`Intellectics' seeks to understand the functions, structure and operation of the human intellect and to test artificial systems to see the extent to which they can substitute or complement such functions. The word itself was introduced in the early 1980s by Wolfgang Bibel to describe the united fields of artificial intelligence and cognitive science. The book collects papers by distinguished researchers, colleagues and former students of Bibel's, all of whom have worked together with him, and who present their work to him here to mark his 60th birthday. The papers discuss significant issues in intellectics and computational logic, ranging across automated deduction, logic programming, the logic-based approach to intellectics, cognitive robotics, knowledge representation and reasoning. Each paper contains new, previously unpublished, reviewed results. The collection is a state of the art account of the current capabilities and limitations of a computational-logic-based approach to intellectics. Readership: Researchers who are convinced that the intelligent behaviour of machines should be based on a rigid formal treatment of knowledge representation and reasoning.

This book constitutes the refereed proceedings of the 38th Annual German Conference on Artificial Intelligence, KI 2015, held in Dresden, Germany, in September 2015. The 15 revised full technical papers presented together with 14 technical communications, 4 doctoral consortium contributions,  and 3 keynotes were carefully reviewed and selected from 58 submissions. The conference provides the opportunity to present a wider range of results and ideas that are of interest to the KI audience, including reports about recent own publications, position papers, and previews of ongoing work.

Die Gesellschaft für Informatik (GI) zeichnet jedes Jahr eine Informatikdissertation durch einen Preis aus. Die Auswahl dieser Dissertation stützt sich auf die von den Universitäten und Hochschulen für diesen Preis vorgeschlagenen Dissertationen. Somit sind die Teilnehmer an dem Auswahlverfahren der GI bereits als "Preisträger" ihrer Hochschule ausgezeichnet.

Das Gebiet der Wissenspräsentation und Inferenz umfaßt einen zentralen Bereich der Intellektik, d.h. des Gebietes der Künstlichen Intelligenz und der Kognitionswissenschaft. Es behandelt einerseits die Fragen nach einer formalen Beschreibung von Wissen jeglicher Art, besonders unter dem Aspekt einer maschinellen Verarbeitung in modernen Computern. Andererseits versucht es, das Alltagsschließen des Menschen so zu formalisieren, daß logische Schlüsse auch von Maschinen ausgeführt werden könnten. Das Buch gibt eine ausführliche Einführung in dieses umfangreiche Gebiet. Dem Studenten dient es im Rahmen einer solchen Vorlesung oder zum Selbststudium als umfassende Unterlage, und der Praktiker zieht einen großen Gewinn aus der Lektüre dieses modernen Stoffes, der in dieser Breite bisher nicht verfügbar war. Darüber hinaus leistet das Buch einen wichtigen Beitrag zur Forschung dadurch, daß viele Ansätze auf diesem Gebiet in ihren inneren Bezügen in ihrer Bedeutung klarer erkennbar werden und so eine solide Basis für die zukünftige Forschungsarbeit geschaffen ist. Der Leser ist nach der Lektüre dieses Werkes in der Lage, sich mit Details der Wissenspräsentation und Inferenz auseinanderzusetzen.

Equations play a vital role in many fields of mathematics, computer science, and artificial intelligence. Therefore, many proposals have been made to integrate equational, functional, and logic programming. This book presents the foundations of equational logic programming. After generalizing logic programming by augmenting programs with a conditional equational theory, the author defines a unifying framework for logic programming, equation solving, universal unification, and term rewriting. Within this framework many known results are developed. In particular, a presentation of the least model and the fixpoint semantics of equational logic programs is followed by a rigorous proof of the soundness and the strong completeness of various proof techniques: SLDE-resolution, where a universal unification procedure replaces the traditional unification algorithm; linear paramodulation and special forms of it such as rewriting and narrowing; complete sets of transformations for conditional equational theories; and lazy resolution combined with any complete set of inference rules for conditional equational theories.

This book constitutes the refereed proceedings of the 20th Annual German Conference on Artificial Intelligence, KI-96, held in Dresden, Germany, in September 1996.The book presents three invited papers together with 23 revised full research papers, nine posters and four systems demonstrations. All contributions were carefully selected from a larger number of excellent submissions, of which a considerable part had been submitted from abroad. The papers address many subareas of AI; however, there is a certain focus on new develpments in theorem proving, knowledge representation, and reasoning.

This book constitutes the refereed proceedings of the 11th European Conference on Logics in Artificial Intelligence, JELIA 2008, held in Dresden, Germany, Liverpool, in September/October 2008. The 32 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 98 submissions. The papers cover a broad range of topics including belief revision, description logics, non-monotonic reasoning, multi-agent systems, probabilistic logic, and temporal logic.
