Just like the previous workshop at VLDB 1999 in Edinburgh, the purpose of this workshop is to promote telecom data management as one of the core research areas in database research and to establish a strong connection between the telecom and database research communities. As I wrote in the preface of those proceedings, data management in telecommuni- tions is an interesting area of research given the fact that both service management and service provisioning are very data intensive, and pose extreme requirements on data management technology. Given the feedback on the previous workshop we decided to keep the same program set-up for this workshop: an invited speaker, a collection of research papers, and a panel discussion. We received 18 good quality papers from which we selected 12 to construct a very interesting program. The program has been divided into four sections. The first section focuses on CDR data warehouse and data mining technology. Data warehousing and data mining around customer usage data remains an important area of interest for telecommunication operators. The growing competition, especially in the mobile market, means that operators have to put more effort into customer retention and satisfaction. The second section focuses on performance issues around databases in telecommunication. Since telecommunication databases are characterized by their extreme requirements, for example in terms of volumes of data to be processed or response times, high volume data management and embedded and real-time data management are key aspects of the telecommunication data management problems in today s operational environments."

This book documents the efforts undertaken by the EG AgentLink Special Interest Group on Agent Mediated Electronic Commerce, SIG AMEC.First and foremost, the book presents a roadmap of research and current technological development in the area of agent mediated electronic commerce.

This volume contains the proceedings of the First International Conference on Advances in Information Systems (ADVIS) held in Izmir (Turkey), 25{27 October, 2000. This conference was dedicated to the memory of Professor Esen Ozkarahan. He was great researcher who made an essential contribution to the development of information systems. This conference was organized by the Computer - gineering Department of Dokuz Eylul University of Izmir. This department was established in 1994 by the founding chairman Professor Ozkarahan and there he worked for the last ve years of his live. The main goal of the conference was to bring together researchers from all around the world working in di erent areas of information systems to share new ideas and to represent their latest results. We received 80 submissions from 30 countries. The Program Committee selected 44 papers for presentation at the conference. The invited and accepted contributions cover a large variety of topics: - neral aspects of information systems, data bases, data warehousing, computer networks, Internet technologies, content-based image retrieval, information - trieval, constraint programming and arti cial intelligence. The success of the conference was dependent upon the hard work of a large number of people. We gratefully acknowledge the members of the Program C- mittee who helped to coordinate the process of refereeing all submitted papers. We also thank all the other specialists who reviewed the papers.

This book constiutes the reviewed proceedings of the 4th International Conference on Cognitive Technology, CT 2001, helds in Warwick, UK in August 2001.

This volume contains a selection of manuscripts referring to lectures presented at the Symposium on Operations Research 1999 (SOR'99) held at the Otto-von-Guericke University Magdeburg, Sep- tember 1 -3, 1999. This international conference took place under the auspices of the German OR society (GOR), and it was the first one organized in Germany since the foundation of GOR by merger of the two predecessor societies (DGOR and GMOOR) in 1998. The Symposium had 420 participants from 22 countries around the world. It attracted academicians and practitioners working in various fields of Operations Research and provided them with the most recent developments and advances in the full spectrum of Operations Research and related areas in economics, mathematics, and computer science. The selection of contributions to SOR'99 accepted by the program committee and the invited pa- pers formed a program which consisted of 265 lectures in 19 sections, including 2 plenary and 19 semi plenary presentations. 119 manuscripts were submitted for publication in the proceedings vo- lume. Due to the page limit for this volume and in order to insure a high quality level of the OR Proceedings a further review procedure had to take place which was strongly supported by the sec- tion chairpersons. It resulted in a selection of 87 manuscripts which are now presented in this volume.

With the unprecedented growth-rate at which data is being collected and stored electronically today in almost all fields of human endeavor, the efficient extraction of useful information from the data available is becoming an increasing scientific challenge and a massive economic need. This book presents thoroughly reviewed and revised full versions of papers presented at a workshop on the topic held during KDD'99 in San Diego, California, USA in August 1999 complemented by several invited chapters and a detailed introductory survey in order to provide complete coverage of the relevant issues. The contributions presented cover all major tasks in data mining including parallel and distributed mining frameworks, associations, sequences, clustering, and classification. All in all, the volume presents the state of the art in the young and dynamic field of parallel and distributed data mining methods. It will be a valuable source of reference for researchers and professionals.

EDBT 2000 is the seventh conference in a series dedicated to the advancement of database technology. This year's conference special theme, \Connect Millions of Users and Data Sources," underscores the importance of databases for the information age that is dawning with the new millennium. The importance - rives not just from the observation that the information age essentially rests on theconvergenceofcommunications, computing, andstorage.Equallyimportant, many of the concepts and techniques underlying the success of databasesystems have independent meaning and impact for today's distributed information s- tems. The papers in the volume should also be seen in this light. The EDBT 2000 conference program includes 30 research papers selected by the program committee out of 187 submissions, covering advances in research, development, and applications of databases. The conference program also - cludes six industry andapplications papers, a panel discussion, six tutorials, and several software demonstrations. The conference features three distinguished - vited speakers: Ashish Gupta discusses database issues in electronic commerce, Stefano Ceri addresses the impact and challenges of XML on databases, and Andreas Reuter shares his views on new perspectives on database technology. The technical contributions presented at the EDBT 2000 conference are colle- ed and preserved in this volume that we are pleased to present to you with the expectation that it will serve as a valuable research and reference tool in your professional life.

This first systematic and self-contained monograph on "Symbolic Data Analysis" presents the most recent methods for analyzing and visualizing symbolic data. It generalizes classical methods of exploratory, statistical and graphical data analysis to the case of complex data where the entries of a data table are, e. g., sets of categories or of numbers, intervals or probability distributions. Typical methods include: graphical displays using Zoom Stars, visualization and feature extraction by symbolic factor analysis, decision trees, discrimination, classification and clustering methods. Several benchmark examples from National Statistical Offices illustrate the usefulness of the methods. The book contains an extensive bibliography and a subject index.

Das Buch zeigt, welche Potentiale sich f r Unternehmen durch eine konsequente Orientierung an den Kundenprozessen und einer kooperativen Zusammenarbeit zwischen Unternehmen ergeben. Eine wichtige Rolle nehmen dabei elektronische Dienstleister (sogenannte WebService-Anbieter) ein, die diese Kooperationsprozesse erst erm glichen oder die elektronischen Services viel effizienter erbringen als jedes einzelne Unternehmen im Netzwerkverbund, z.B. f r den Zahlungsverkehr und die Logistik. Dazu werden anhand anschaulicher Beispiele aus der Praxis methodische Vorschl ge zur Gestaltung des Kundenprozesses, zum Portaldesign und zur Kooperationsprozessanalyse und Out-tasking sowie Architekturen f r Kooperationsprozesse und WebServices entwickelt.

If you are sitting in a basement room without a view - not to mention the bars in front of the windows - and writing a book, then you better have good company. I had the best company you could imagine. Waltraud Hiltl, Katja Markert, Martin Romacker, Klemens Schnattinger, Andreas Klee and I shared very little o?ce space, but plenty of chocolate, co?ee, champagne, and enthusiasm for our research. North German coolness and creativity sprang mostly from my colleagues in the second ?oor. I learned a lot from and laughed a lot with Nobi Br]oker, Susanne (Sue) Schacht, Manfred Klenner, Peter Neuhaus, Stefan Schulz, and Michael Strube. I thank my friend and partner Angela R]osch for motivational and te- nical support and for living together with someone who cares about strange things, works too much and does not improve in any way over the years. Special thanks go to my family who sometimes wondered what was going on when I started talking enthusiastically about "semantics," but they never let wane their encouragement for me. Kornel Marco provided great service by implementing parts of the system presented in this book. Joe Bush helped me polish up the text with his capabilities as an American native speaker. Remaining errors are entirely my fault and due to my lack of diligence. This book would not have seen the light of day without the dissertation grant through the Graduiertenkolleg "Menschliche & Maschinelle Intelligenz" funded by the Deutsche Forschungsgemeinschaft (DFG)."
