The Database and Expert Systems Applications - DEXA - conferences are dedi­ cated to providing an international forum for the presentation of applications in the database and expert systems field, for the exchange of ideas and experiences, and for defining requirements for the future systems in these fields. After the very promising DEXA 90 in Vienna, Austria, we hope to have successfully established wjth this year's DEXA 91 a stage where scientists from diverse fields interested in application-oriented research can present and discuss their work. This year there was a total of more than 250 submitted papers from 28 different countries, in all continents. Only 98 of the papers could be accepted. The collection of papers in these proceedings offers a cross-section of the issues facing the area of databases and expert systems, i.e., topics of basic research interest on one hand and questions occurring when developing applications on the other. Major credit for the success of the conference goes to all of our colleagues who submitted papers for consideration and to those who have organized and chaired the panel sessions. Many persons contributed numerous hours to organize this conference. The names of most of them will appear on the following pages. In particular we wish to thank the Organization Committee Chairmen Johann Gordesch, A Min Tjoa, and Roland Wag­ ner, who also helped establishing the program. Special thanks also go to Gabriella Wagner and Anke Ruckert. Dimitris Karagiannis General Conference Chairman Contents Conference Committee.

This book draws new attention to domain-specific conceptual modeling by presenting the work of thought leaders who have designed and deployed specific modeling methods. It provides hands-on guidance on how to build models in a particular domain, such as requirements engineering, business process modeling or enterprise architecture. In addition to these results, it also puts forward ideas for future developments. All this is enriched with exercises, case studies, detailed references and further related information. All domain-specific methods described in this volume also have a tool implementation within the OMiLAB Collaborative Environment – a dedicated research and experimentation space for modeling method engineering at the University of Vienna, Austria – making these advances accessible to a wider community of further developers and users. The collection of works presented here will benefit experts and practitioners from academia and industry alike, including members ofthe conceptual modeling community as well as lecturers and students.

The biennial PAKM Conference Series o?ers a communication platform and meeting ground for practitioners and researchers involved in developing and deploying advanced business solutions for the management of knowledge in - ganizations. PAKM is a forum for people to share their views, exchange ideas, develop new insights, and envision completely new kinds of knowledge mana- ment solutions. PAKM 2006, the Sixth International Conference on Practical Aspects of Knowledge Management, was held again in Vienna. It was a milestone for two reasons: First, it marked an anniversary – 10 years of PAKM conferences. The ?rst conference was held in Basel, Switzerland, in 1996, followed by the conf- ences in 1998 and 2000, in Basel as well. After that PAKM moved to Vienna where it was held in 2002, 2004, and 2006. Secondly, from now on PAKM will be “on tour”: It will be organized by di?erent people and be hosted at di?erent places all over the world. The PAKM Steering Committee will be responsible for selecting the conference chairs and the conference locations. The Steering Committee will also be responsible for the direction the PAKM conferences will take and will ensure their continuing high quality. For this year’s conference we received 123 submissions from 30 countries.

Knowledge-based systems have been successfully developed in practice for a number of years. However, they are often "only" stand-alone systems: integrating them into existing information environments, eg making available real production data to an expert system, often either fails or is only solved in a dissatisfying way. Possible reasons for this might be on one hand the lack of know-how about the different features of various experimental AI techniques, and on the other the lack of more classical information and database system technology. The special interest groups "Knowledge Representation" and "Methods for the Development of Information Systems and their Application" of the German Informatics Society (GI) organized a joint workshop in Ulm in March 1990 to discuss the integration of Artificial Intelligence and database technology. This volume contains the proceedings of the workshop. This book of proceedings on computer science, AI, information systems, knowledge-based management systems, software engineering, CAD and office systems is intended for researchers, practitioners, graduate students.

This volume constitutes the proceedings of the 5th International Conference on Database and Expert Systems Applications (DEXA '94), held in Athens, Greece in September 1994. The 78 papers presented were selected from more than 300 submissions and give a comprehensive view of advanced applications of databases and expert systems. Among the topics covered are object-oriented, temporal, active, geographical, hypermedia and distributed databases, data management, cooperative office applications, object-oriented modelling, industrial applications, conceptual modelling, legal systems, evolving environments, knowledge engineering, information retrieval, advanced querying, medical systems, and CIM.

Following two successful events in Guilin, People’s Republic of China (KSEM 2006) and in Melbourne, Australia (KSEM 2007) the third event in this conference series was held for the first time in Europe, namely, in Vienna, Austria. KSEM 2009 aimed to be a communication platform and meeting ground for research on knowledge science, engineering and management, attracting high-quality, state-of-the-art publications from all over the world. It offers an exceptional opportunity for presenting original work, technological advances, practical problems and concerns of the research community. The importance of studying “knowledge” from different viewpoints such as science, engineering and management has been widely acknowledged. The accelerating pace of the "Internet age" challenges organizations to compress communication and innovation cycles to achieve a faster return on investment for knowledge. Thus, next-generation business solutions must be focused on supporting the creation of value by adding knowledge-rich components as an integral part to the work process. Therefore, an integrated approach is needed, which combines issues from a large array of knowledge fields such as science, engineering and management. Based on the reviews by the members of the Program Committee and the additional reviewers, 42 papers were selected for this year’s conference. Additionally, two discussion panels dealing with “Knowware: The Third Star after Hardware and Software” and “Required Knowledge for Delivering Services” took place under the auspices of the conference. The papers and the discussions covered a great variety of approaches of knowledge science, management and engineering, thus making KSEM a unique conference.
