TUTORIALS
TUTORIAL 1
DESIGNING ENTERPRISE INFORMATION SYSTEMS
WITH UML
Leszek A. Maciaszek, Macquarie University (Australia)
About the author: The presenter is an Associate Professor of Computing at
Macquarie University, Sydney, Australia. Originally from Poland, he has worked
and consulted interchangeably in academia and industry in countries such as
U.S.A., Kuwait, Germany and France. He moved to Australia in 1985. Leszek A.
Maciaszek enjoys excellent reputation as a teacher and presenter of training
courses to industry. He has an extensive consulting experience, frequently to
large international corporations. His research has been in databases, objectoriented technology, software engineering, and development of large-scale
business information systems. Leszek A. Maciaszek published over eighty
publications, including a reference book "Database Design and Implementation"
(Prentice Hall, 1990) and a textbook "Requirements Analysis and System
Design. Developing Information Systems with UML" (Addison Wesley, 2001).
Short description
The system design encompasses two major issues: the architectural design
and the detailed design. The architectural design involves layered organisation
of classes and packages, assignment of processes to computing facilities, reuse
and component management. The detailed design addresses collaboration
models required for the realisation of system functionality captured in use cases.
In the tutorial, the presenter will identify ways to:
 harness the complexity of large design models,
 improve software architectures,
 facilitate software readability, maintainability and scalability,
 promote layered structuring of objects,
 handle module and component integration,
 model collaboration between GUI and persistent database objects,
 conduct round-trip engineering with database, etc.

DATA MINING TECHNIQUES AND TOOLS FOR
INFORMATION FILTERING
Michalis Vazirgiannis
Athens University of Economics & Business (Greece)
About the author: Dr. Michalis Vazirgiannis acquired a Ph.D. degree in
1994 (Dept. of Informatics, U. Athens, Greece). The research area was Object
Oriented modeling of Hypermedia Information Networks. Since then, he have
conducted research in the Knowledge & DB Lab (Prof. T.Sellis group, N.T.U.
Athens), in GMD-IPSI, Germany, in Fern University (Prof R.H.Gueting group in
Hagen, Germany) and in project VERSO in INRIA/Paris. His research interests
and work range from Interactive Multimedia Information Systems, to
Spatiotemporal databases, Uncertainty and Data Mining. In 1997 he earned the
position of Lecturer in "Database Systems" in the Dept. of Informatics of Athens
University of Economic and Business, Greece.
Abstract:
The tutorial starts with an introduction on the fundamental concepts of data
mining. Then we present techniques from the area of data pre-processing and
cleaning, namely techniques for cleaning and maintaining the consistency of the
data. An important topic covered is cluster analysis (unsupervised learning).
Clustering aims at discovering groups and identifying interesting distributions
and patterns in data sets and is applicable in many application domains in
engineering and social sciences. We present a survey of clustering methods
and approaches available in literature in a comparative way. Another important
issue is the validity of the clustering schemes resulting from applying algorithms.
This is also related to the inherent features of the data set under concern. We
18
review and compare clustering validity measures available in the literature. We
also present basic aspects of association rules extraction, on uncertainty
handling and quality assessment in a data mining context. Furthermore, we
present case studies from data mining in medical data and we address new
research directions.

Abstract:
Web sites are progressively evolving from brows able, read-only information
repositories that exploit the web to interact with their users, to web-based
applications, combining navigation and search capabilities with operations and
transactions typical of information systems. In parallel, the possibility of
accessing web-based contents and services through a number of different
devices, ranging from full-fledged desktop computers, to Personal Digital
Assistants (PDA's), to mobile phones, to set-top boxes connected to TV’s,
makes web applications ubiquitous, i.e., accessible anywhere at any time.
Ubiquitous Web Applications (UWA's for short) reveal a number of aspects,
which make them different with respect to conventional data-intensive
19
applications, and must be taken into account throughout the whole application
lifecycle, from requirements to implementation. UWA's are executed in a Webbased environment, where the paradigm for presenting and accessing
information is hypermedia-like. Thus UWA’s have a mixed nature - hypermedia
and transactional, where hypertext structures and operation capabilities are
strongly intertwined. In addition, the ubiquitous nature of a UWA implies that the
application has to take into account the different constraints of different devices,
comprising display size, local storage size, method of input and computing
speed as well as network capacity. At the same time, ubiquity introduces new
requirements on how the application tunes itself to the end user: each user may
wish to get information, navigation patterns, lay-out, and services, that are
tailored not only to his/her specific profile but also to the current situation of use,
in its temporal and environmental aspects. Thus Ubiquitous Web Applications
must be at the same time device-aware, user-aware, and context-of-use-aware,
and require sophisticate forms of customization.
After an analysis of the novel requirements of UWA's, this talk will focus on
their impact on the design process, and will discuss problems and challenges
related to modeling information and navigation structures, operations and
transactions, and customization mechanisms for this class of applications.
FROM WORKFLOWS TO SERVICE COMPOSITION IN
VIRTUAL ENTERPRISES
Marek Rusinkiewicz
Information and Computer Science Research Laboratory
Telcordia Technologies
About the author: Professor Dr. Marek Rusinkewicz is a leading scientist in
information systems and databases. He is the member of IFIP WG 6.2 Working
Group on Databases and member of Editorial Boards of the International
Journal on “Distributed and Parallel Databases”, "International Journal on
Cooperative Information Systems", and "IEEE Transactions on Knowledge and
Data Engineering".
Abstract:
Workflow technologies have been used extensively to support processbased integration of activities within enterprises and are at the core of emerging
Enterprise Integration Platform (EIP) technologies. Recently, a new abstraction
of electronic services has begun to receive a lot of attention among researchers
and in the vendor community. Electronic services provide the basis for creation
of virtual enterprises (VE), which combine services from multiple providers. In
this talk, we will discuss the advances that are needed to provide support for
VEs. These include the ability to advertise, broker, synchronize and optimize
20
the services. We will discuss the infrastructure needed to support VE
application, show a prototype demo, and list important research problems that
need to be solved.

Abstract:
Our interdisciplinary project "Warburg Electronic Library (WEL)" – Art History
and Computer Science combined forces - uses as a test-bed application a large
multimedia collection called "Index for Political Iconography (PI)".
The PI captures concepts from the "Political Space" through an extensive
system of interrelated subject terms. Subject term and subject index are
ontological concepts "regarding entities, especially abstract entities to be
admitted into a language of description" [Webster] and are based on the
semantic principles of aggregation, classification, generalization/specialization
and association.
Since the semantics of subject terms is precisely what their class extensions
contain, the main objective of subject-oriented work on PI-like systems is to
carry subject term extensions „to their completion“. On the other hand, the
notion of “completion“ depends on the view of the person or group who does the
21
subject-oriented work and requires, therefore, personalized relationships
between content and work.
In content management there is high interest in such "languages of
description" and how people work with them:
- what models and languages are required to make subject-oriented work
more explicit?
- what kind of support a digital library such as the WEL for subject-oriented
work can provide?
- what is the role of personalized and cooperating digital libraries?
- to what extent do we already understand requirements and architectures
of generic subject-oriented working environments?
- and, as specifically emphasized in the PI: use of reference by icon, index,
and symbol in subject-oriented work?
In this paper we discuss initial demands on models and environments for
subject-oriented work and outline our WEL systems and application experience.
Our interdisciplinary research on subject-oriented work also puts our
previous computer science research in polymorphic type systems, persistent
language implementation, abstract machine architectures, models for migrating
threads etc. into a new perspective and relates it to our commercial interests in
online content management.

CONFERENCE VENUE
The Conference will be held at the Vilnius Gediminas Technical
University (http://www.vtu.lt/english/vgtu/) in Vilnius, Lithuania.
Lithuania (http://neris.mii.lt/) is a small, beautiful country lying on the
southeastern coast of the Baltic Sea and inhabited by one of the Baltic
nations. The Lithuanians have preserved one of the oldest language, a
unique culture and unique customs.
Vilnius (http://www.vilnius.sav.lt/tourism/) is the capital of Lithuania. It
is a city that has to be explored. A day walking through the narrow,
winding streets will give you a lot of impression. There is plenty to see.
Masterpieces of local gothic, baroque and classicism, Gediminas
Castle, folk art, museums, monuments of the former Soviet Empire,
23
restful cafes, swinging bars, modern night clubs, handsome and
imposing restaurants.
The largest Old Town in Eastern Europe gives you the feeling that
you are walking through a museum, for practically every building is a
relic of a sort. 27 km from Vilnius lays the ancient capital of Lithuania
Trakai (http://www.tourism.lt/region/vilnius/trakai.htm). The Trakai
Castle, an original relic of the Middle Ages, has survived on one of the
islands on the Galve Lake to this day. 100 km from Vilnius lays the
Lithuania's second largest city Kaunas (http://www.kaunas.lt/english/).
There is a number of interesting museums, such as the Ciurlionis
Museum with an exposition of more than 200 canvases by the great
Lithuanian artist M.K. Ciurlionis, the exposition of folk "devil" sculptures,
and the IXth Fort Museum, a memorial to the victims of fascism.
