Trends in Artificial Intelligence


Book Description

This book collects the scientific papers presented at the 2nd Congress of the Italian Association for Artificial Intelligence, held in Palermo in October 1991. It displays the state of the art of both Italian and European scientific research in AI. The book begins with an invited paper by W. Wahlster et al. The bulk of the book is then divided into five parts on: - Knowledge representation (18 papers), - Knowledge acquisition (5 papers), - Natural language (5 papers), - Perception and robotics (5 papers), - Architecture and technologies (5 papers). A section containing short papers completes the book. The high quality of the papers reflects massive research activity mainly devoted to the theoretical aspects of AI, but clearly aimed at consolidating the results already achieved. Several contributions are oriented to the technological aspects of AI.




Informationssysteme und Künstliche Intelligenz: Modellierung


Book Description

Neuere Entwicklungen im Datenbank- und Informationssystembereich sind u.a. gekennzeichnet durch die Bereitstellung sehr m{chtiger semantischer bzw. objektorientierter Datenmodelle, um den Anforderungen aus sogenannten Nicht-Standardanwendungen wie z.B. dem B}robereich gerecht zu werden. Daraus ergeben sich unmittelbar neue Problemstellungen imHinblick auf die Entwurfs- und Modellierungsaufgaben, die mit dem Einsatz derartiger m{chtiger Datenmodelle verbunden sind. Betrachtet manandererseits Entwicklungstendenzen im Bereich der K}nstlichen Intelligenz, so wird Fragen der systematischen Entwicklung Wissensbasierter Systeme eine immer gr|~ere Wichtigkeit beigemessen. Dabei spielen u.a. Phasen-Systeme und damit verbunden der Aufbau geeigneter Modelle eine zentrale Rolle. Dementsprechend hat der 2. Workshop "Informationssysteme und K}nstliche Intelligenz" gerade das Gebiet der Modellierung als generelles Thema. Zielsetzung ist dabei, auf dem Gebiet derModellierung Gemeinsamkeiten und Unterschiede von Problemstellungen bzw. L|sungsans{tzen, die in den Fachdisziplinen K}nstliche Intelligenz und Informationssysteme/Datenbanksysteme identifiziert bzw. entwickelt worden sind, herauszuarbeiten. Damit soll gleichzeitig der Gedankenaustausch zwischen den beteiligten Fachdisziplinen gef|rdertund die Zusammenarbeit }ber Fachdisziplinen hinweg verbessert werden.




Computational Intelligence, II


Book Description

The focus of this volume is ``Heterogeneous Knowledge and Problem Solving Integration'', i.e. the combined use of different knowledge representation and problem solving paradigms.This is a central topic for the design and implementation of problem solving systems, since, from a pragmatic and engineering standpoint, the solution of a large class of problems cannot take place within one single representation language or problem solving paradigm. Heterogeneous systems represent not only a pragmatic answer, but also a theoretical alternative to the homogeneous paradigms.




Sorts and Types in Artificial Intelligence


Book Description

The aim of this book is to reflect the substantial re- search done in Artificial Intelligence on sorts and types. The main contributions come from knowledge representation and theorem proving and important impulses come from the "application areas", i.e. natural language (understanding) systems, computational linguistics, and logic programming. The workshop brought together researchers from logic, theoretical computer science, theorem proving, knowledge representation, linguistics, logic programming and qualitative reasoning.




KADS


Book Description

KADS is a structured methodology for the development of knowledge based systems which has been adopted throughout the world by academic and industrial professionals alike. KADS approaches development as a modeling activity. Two key characteristics of KADS are the use of multiple models to cope with the complexity of knowledge engineering and the use of knowledge-level descriptions as an immediate model between system design and expertise data. The result is that KADS enables effective KBS construction by building a computational model of desired behavior for a particular problem domain. KADS contains three section: the Theoretical Basis of KADS, Languages and Tools, and Applications. Together they form a comprehensive sourcebook of the how and why of the KADS methodology. KADS will be required reading for all academic and industrial professionals concerned with building knowledge-based systems. It will also be a valuable source for students of knowledge acquisition and KBS. * SPECIAL FEATURES: * KADS is the most widely used commercial structured methodology for KBS development in Europe and is becoming one of the few significant AI exports to the US. * Describes KADS from its Theoretical Basis, through Language and Tool Developments, to real Applications.




Theorem Proving with Analytic Tableaux and Related Methods


Book Description

This books presents the refereed proceedings of the Fifth International Workshop on Analytic Tableaux and Related Methods, TABLEAUX '96, held in Terrasini near Palermo, Italy, in May 1996. The 18 full revised papers included together with two invited papers present state-of-the-art results in this dynamic area of research. Besides more traditional aspects of tableaux reasoning, the collection also contains several papers dealing with other approaches to automated reasoning. The spectrum of logics dealt with covers several nonclassical logics, including modal, intuitionistic, many-valued, temporal and linear logic.




The Semantics of Prepositions

Konnektionismus in Artificial Intelligence und Kognitionsforschung


Book Description

Konnektionismus als Methode, Modellvorstellung, aber auch als Weltbild dringt immer mehr in die Domänen der AI (KI) und Kognitionsforschung vor. Obwohl es eine Reihe von Konferenzen gibt, die künstliche neuronale Netzwerke - die Basis des Konnektionismus - zum Inhalt haben, scheint dem Bereich der Intelligenzforschung und -modellierung mit Hilfe solcher Netzwerke vergleichsweise noch wenig Raum geboten zu werden. Die Konferenz, die vom 18. bis 21. September 1990 in Salzburg stattgefunden hat und deren Proceedings in diesem Band vorliegen, sollte diese Lücke schließen. Sie hat in Form von Vorträgen, Workshops und Panels Arbeiten zusammengebracht, die sich mit Anwendungen neuronaler Netzwerke auf Probleme der AI, mit grundlegenden Aspekten von massivem Parallelismus und Netzwerkverarbeitung in der AI sowie mit theoretischen Implikationen der Modelle auf die AI und die Kognitionsforschung im allgemeinen beschäftigen. Die vorliegenden Beiträge geben einen guten Einblick in den Stand der Forschung - besonders im deutschsprachigen Raum, aber auch darüber hinausgehend.




Principles of Semantic Networks


Book Description

Principles of Semantic Networks: Explorations in the Representation of Knowledge provides information pertinent to the theory and applications of semantic networks. This book deals with issues in knowledge representation, which discusses theoretical topics independent of particular implementations. Organized into three parts encompassing 19 chapters, this book begins with an overview of semantic network structure for representing knowledge as a pattern of interconnected nodes and arcs. This text then analyzes the concepts of subsumption and taxonomy and synthesizes a framework that integrates many previous approaches and goes beyond them to provide an account of abstract and partially defines concepts. Other chapters consider formal analyses, which treat the methods of reasoning with semantic networks and their computational complexity. This book discusses as well encoding linguistic knowledge. The final chapter deals with a formal approach to knowledge representation that builds on ideas originating outside the artificial intelligence literature in research on foundations for programming languages. This book is a valuable resource for mathematicians.




Logic Programming and Nonmonotonic Reasoning


Book Description

This volume contains the refereed proceedings of the 13th International Conference on Logic Programming and Nonmonotonic Reasoning, LPNMR 2015, held in September 2015 in Lexington, KY, USA. The 290long and 11 short papers presented together with 3 invited talks, the paper reporting on the Answer Set Programming competition, and four papers presented by LPNMR student attendees at the doctoral consortium were carefully reviewed and selected from 60 submissions. LPNMR is a forum for exchanging ideas on declarative logic programming, nonmonotonic reasoning, and knowledge representation. The aim of the LPNMR conferences is to facilitate interactions between researchers interested in the design and implementation of logic-based programming languages and database systems, and researchers who work in the areas of knowledge representation and nonmonotonic reasoning.
