The Semantic Web combines the descriptive languages RDF (Resource Description Framework) and OWL (Web Ontology Language), with the data-centric, customizable XML (eXtensible Mark-up Language) to provide descriptions of the content of Web documents. These machine-interpretable descriptions allow more intelligent software systems to be written, automating the analysis and exploitation of web-based information. Software agents will be able to create automatically new services from already published services, with potentially huge implications for models of e-Business.Semantic Web Technologies provides a comprehensive overview of key semantic knowledge technologies and research.   The authors explain (semi-)automatic ontology generation and metadata extraction in depth, along with ontology management and mediation. Further chapters examine how Semantic Web technology is being applied in knowledge management (“Semantic Information Access”) and in the next generation of Web services.Semantic Web Technologies: Provides a comprehensive exposition of the state-of-the art in Semantic Web research and key technologies.Explains the use of ontologies and metadata to achieve machine-interpretability.Describes methods for ontology learning and metadata generation.Discusses ontology management and evolution, covering ontology change detection and propagation, ontology dependency and mediation.Illustrates the theoretical concepts with three case studies on industrial applications in digital libraries, the legal sector and the telecommunication industry.Graduate and advanced undergraduate students, academic and industrial researchers in the field will all find Semantic Web Technologies an essential guide to the technologies of the Semantic Web.

Intelligent information processing has become one of the key issues on our way to a knowledge society. Research has led to exciting advances in technologies that will shape our future. Knowledge-based systems have matured to provide services in a well-founded ontological framework, and intelligent knowledge management can be supported by tools that are ready for practical applications. This work presents contemporary research with special emphasis on knowledge-based system architecture and intelligent information management. It comprises the proceedings of the Conference on Intelligent Information Processing (IIP 2002) held in conjunction with the 17th World Computer Congress, which was sponsored by the International Federation of Information Processing (IFIP) and which convened in Montreal, Quebec, Canada, in August 2002. The conference represented a major activity of IFIP Technical Committee 12 (Artificial Intelligence), Working Group 12.5, which is dedicated to "knowledge-oriented development of applications".This Working Group brings together an international community of scientists concerned with the use of knowledge-based techniques in the engineering of real-world software systems.

Damit Softwareproduktionsumgebungen in grosseren Softwareentwicklungsprojekten wirkungsvoll eingesetzt werden konnen, mussen sie leistungsfahige Unterstutzungsfunktionen anbieten, die auf die Bedurfnisse der beteiligten Projektmitarbeiter ausgerichtet sind. In dieser Arbeit werden Konzepte fur eine verteilte wissensbasierte Softwareproduktionsumgebung, DIKOS (Distributed Knowledge-Based Software Engineering Environment), entwickelt, in deren Wissensbasis alle fur ein Softwareentwicklungsprojekt relevanten Informationen verwaltet werden. Dabei werden insbesondere Aspekte der Kooperation und Kommunikation der beteiligten Projektmitarbeiter betrachtet. Zur Beschreibung der in der DIKOS-Wissensbasis verwalteten Objekte sowie der zur Manipulation der Objekte definierten Funktionen werden THM-Netze eingefuhrt, die Konzepte semantischer Datenmodelle mit Pradikat-Transitions-Netzen vereinigen und zusatzlich uber Modellierungskonzepte zur Beschreibung von Zeitaspekten verfugen. Unter Verwendung von THM-Netzen wird ein Benutzerinformationssystem formal spezifiziert, das die Kooperation und Kommunikation zwischen den Projektmitarbeitern unterstutzt und teilweise automatisiert.Abschliessend wird die grundlegende Gestaltung der DIKOS-Benutzerschnittstelle beschrieben, wobei insbesondere die Dialogfunktionen des Benutzerinformationssystems betrachtet werden. Es wird ein abstraktes Dialogmodell eingefuhrt, das die streng formale Spezifikation interaktiver Benutzerschnittstellen ermoglicht.

This volume contains the papers presented at the International Scientific Symposium "Natural Language and Logic" held in Hamburg in May 1989. The aim of the papers is to present and discuss latest developments in the application of logic-based meth- ods for natural language understanding. Logic-based methods have gained in importance in the field of computational linguistics as well as for representing various types of knowledge in natural language understanding systems. The volume gives an overview of recent results achieved within the LILOG project (LInguistic and LOgic methods for understanding German texts) - one of the largest research projects in the field of text understanding - as well as within related natural language understanding systems.

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.

This book constitutes the refereed proceedings of the 11th European Workshop on Knowledge Acquisition, Modeling and Management, EKAW '99, held at Dagstuhl Castle, Germany in May 1999. The volume presents 16 revised full papers and 15 revised short papers were carefully reviewed and selected form a high number of submissions. Also included are two invited papers. The papers address issues of knowledge acquisition (i.e., the process of extracting, creating, structuring knowledge, etc.), of knowledge-level modeling for knowledge-based systems, and of applying and redefining this work in a knowledge management and knowledge engineering context.

In just a few years, service-oriented architectures (SOA) and Web services not only gained considerable interest in computer science research, they were also taken up with unanimity by all major international players in the IT industry. However, and in spite of all existing standards, in most SOA applications much human intervention is still required, for example to interpret the semantics of informal descriptions or to harmonize incompatible data schemata. Semantic Web services combine Web services communication technology with the intelligent processing of ontology-based metadata to achieve highly integrated enterprise application integration scenarios, for service look-up, schema matching, or protocol negotiation, for example. Rudi Studer and his team deliver a self-contained compendium about this exciting field, starting with the basic standards and technologies and also including advanced applications in eGovernment and eHealth. The contributions provide both the theoretical background and the practical knowledge necessary to understand the essential ideas and to design new cutting-edge applications. They address computer science students as well as researchers in academia and industry who need a concise introduction and state-of-the-art survey of current research, and the book can easily be used as the basis of a specialized course on Web services or Semantic Web applications. In addition, IT professionals will be able to assess the potential and possible benefits of this new technology.

An ontology is a formal description of concepts and relationships that can exist for a community of human and/or machine agents. The notion of ontologies is crucial for the purpose of enabling knowledge sharing and reuse. The Handbook on Ontologies provides a comprehensive overview of the current status and future prospectives of the field of ontologies considering ontology languages, ontology engineering methods, example ontologies, infrastructures and technologies for ontologies, and how to bring this all into ontology-based infrastructures and applications that are among the best of their kind. The field of ontologies has tremendously developed and grown in the five years since the first edition of the "Handbook on Ontologies". Therefore, its revision includes 21 completely new chapters as well as a major re-working of 15 chapters transferred to this second edition.
