Call for Participation
6TH INTERNATIONAL CONFERENCE ON DATABASE THEORY(ICDT '97)
Delphi, Greece, January 8-10, 1997In cooperation with
ACM COMPUTER SOCIETY and IEEE COMPUTER SOCIETY
ICDT is a biannual international conference on theoretical aspects of databases and a forum for communicating research advances on the principles of database systems. Previous ICDT conferences were held in Rome (1986), Bruges (1988), Paris (1990), Berlin (1992), and Prague (1995). Since 1992, ICDT has been merged with the Symposium on Mathematical Fundamentals of Database Systems (MFDBS), another series of conferences on theoretical aspects of database systems that was initiated in Dresden (1987), and continued in Visegrad (1989) and Rostock (1991).
INVITED TALKSSpeaker: S. Abiteboul (INRIA and Stanford University)
Title: Querying Semi-Structured Data
Semi-structured data can be found in many data sources available electronically (most notably in the WWW). They also arise naturally as the result of the integration of independent heterogeneous sources. In such contexts, the structure of data is not as regular or rigid as in standard databases systems, e.g., in the relational or object-oriented database systems. Also, the notion of schema is altered in essential ways, e.g., the schema may become implicit.About the speaker:
Serge Abiteboul obtained his Ph.D. from U.S.C, Los Angeles, in 1982, and a Th`ese d'Etat from Paris University, Orsay, in 1985. He is Senior Researcher at I.N.R.I.A., Rocquencourt, France where he managed a Database Group from 1989 to 1995. He is also Maitre de Conf'erence at Ecole Polytechnique. He is currently visiting for two years the Computer Science Dept. at Stanford U.
Speaker: J. Ullman (Stanford University)
Title: Information Integration Using Logical Views
A number of ideas concerning information-integration tools can be thought of as constructing answers to queries using views that represent the capabilities of information sources. We review the formal basis of these techniques, which are closely related to containment algorithms for conjunctive queries and/or datalog programs. Then we compare the approaches taken by AT&T Labs' "Information Manifold" and the Stanford "Tsimmis" project in these terms.About the speaker:
Jeff Ullman is the Stanford W. Ascherman Professor of Engineering and acting chair of the Department of Computer Science at Stanford. He received the B.S. degree from Columbia University in 1963 and the PhD from Princeton in 1966. He has served as chair of the CS-GRE Examination board, Member of the ACM Council, Chair of the New York State CS Doctoral Evaluation Board, on several NSF advisory boards, and is past or present editor of several journals. He is presently a member of the Computing Research Association Board. Ullman was elected to the National Academy of Engineering in 1989, has held Guggenheim and Einstein Fellowships, and is the 1996 winner of the Sigmod Contributions Award. He is the author of 14 books, including a 2-volume series on Database Systems. His research interests include information integration, warehouse design, and data mining.
INVITED TUTORIALSpeaker: H. Mannila (University of Helsinki)
Title: Methods of data mining
Data mining, also called knowledge discovery in databases, aims at the discovery of interesting knowledge from large masses of data. We review some recent developments in data mining methods for relational, sequential, and time-series data, and present some theoretical results and challenges in the area.About the speaker:
Heikki Mannila is a professor of computer science at the University of Helsinki, where he also obtained his Ph.D. in 1985. After that he has been an associate professor at the Universities of Tampere and Helsinki, a visiting professor at the Technical University of Vienna, and a guest researcher at the Max Planck Institut fur Informatik in Saarbrucken. He has also worked at the National Public Health Institution in Helsinki, as well as consultant in industry. His research interests include data mining, machine learning, database design, and text databases. He is the coauthor of the book "Design of Relational Databases" (Addison-Wesley) as well as numerous articles in algorithms, databases, machine learning and data mining. He is one of the editors-in-chief of the new scientifc journal "Data Mining and Knowledge Discovery".

LOCATIONICDT 97 will be held at the European Cultural Center of Delphi, Greece. Delphi (elevation 573 m.) is located in a magnificent natural setting about 170 km N/W of Athens on the undercliffs of Mount Parnassus. The drive from Athens to Delphi takes about three hours.
Delphi hosts one of the most significant archaeological sites in Greece. Although today it is just a small village, historically Delphi has been one of the cornerstones of ancient Greek civilization. Indeed, in antiquity Delphi was the seat of the oracle of Apollo, which was particularly active during the 7th and the 6th centuries BC and had to be consulted for essentially every major political decision. Ancient Greeks considered Delphi to be the "navel of the world". The shrine was administered by a panhellenic confederation, which every four years organized the Pythian Games; these were second only to the Olympic Games, but with more prominence on music and drama, as they were dedicated to Apollo.
WEATHERJanuary is winter time in Greece. The temperature at Delphi in January typically ranges from 5 to 15 degrees C (41-59 degrees F), with a small probability of being lower than 5 degrees C (41 degrees F).
CURRENCY AND EXCHANGEThe Greek currency is the drachma (DR). In September 1996, 1 US Dollar was approximately 235 DR. Currencey can be exchanged either at the Athens airport or in Delphi.
TIMEGreece uses +2 hour GMT (Greenwich Mean Time).
THINGS TO DODelphi's archeological site has many interesting monuments and temples, including the sanctuary of Apollo, the theatre where the Delphic festivals were held, the stadium, the Kastalia Fountain where the Pythia, priestess of Apollo, would bathe before uttering her oracular utterances, and the tholos or rotunda, one of the most remarkable architectural constructions of antiquity (depicted on the conference poster). The collection of the Delphi museum consists exclusively of objects found on the archaeological site, including the famous bronze statue of the charioteer and an ancient copy of the sacred stone "omphalos" (the "navel of the world").
In Delphi and the surrounding villages you can find tavernas, restaurants, coffee houses, and bars.
From Delphi you can visit the ski facilities of Mount Parnassus (elevation 2400 m), the town of Itea (17 km), a pleasant summer resort by the sea, the town of Amfissa (22 km), surrounded by a forest of olive trees, and the monastery of Hosios Loukas (36 km), an outstanding example of Byzantine art and architecture.
