PKDD’99 Discovery Challenge
A Collaborative Effort in Knowledge
Discovery from Databases
Call for Contributions
Knowledge discovery in real-world databases requires a
broad scope of techniques and forms of knowledge. Both the knowledge
and the applied methods should fit the discovery tasks and should
adapt to knowledge hidden in the data. PKDD'99 Discovery Challenge
will encourage a collaborative research effort, a broad and unified view of
knowledge and methods of discovery, and emphasis on business problems and solutions
to those problems.
Time and place
The Discovery Challenge will be held as a part of the 3rd European Conference on Principles and
Practice of Knowledge Discovery in Databases (PKDD’99), September 15 - 18, 1999, Prague, Czech
Republic. Only those registered for PKDD’99 can participate in the discovery challenge.
Two real-world dataset are available to all prospective
PKDD'99 conference participants.
Each dataset is described in a separate document. The meaning of data
as well as a sample of exploration tasks are included in each
In the financial domain, the dataset consists of 8 tables describing clients
of a bank, their accounts, transactions, permanent orders, granted loans and
issued credit cards.
In the medical domain, the dataset consists of 3 tables describing
patients with collagen diseases.
Discovery Challenge guidelines
- Each participant can use any KDD techniques and discover as much
knowledge as possible.
Ideally each submitted contribution will include
Since the results may be unexpected, the final applications may be
different from those initially proposed.
- the proposed business objectives (goals that may be of interest to
- a brief summary of datamining effort; this summary may include
the data preprocessing tasks like data extraction, sampling, data integration and
homogenization, data cleaning, data transformation, the data mining step as well as the
evaluation criteria apporwed,
- presentation of the discovered knowledge, and
- an explanation for database users how they can apply the discovered knowledge.
- In order to reach a common framework for comparisons, the
presentation of the discovered knowledge should include a clear
summary of the predictions it makes possible. Ideally, such a summary
shows parts of the entire dataset that can be removed from data
because they can be predicted by the discovered knowledge nad the remaining data.
- The deadline for camera-ready contributions is August 9, 1999. Soon
afterwards each database coordinator and the Discovery Challenge Chair
issue the schedule of presentations.
- All presentation will be done during a sequence of special
sessions. The time allocated for each presentation will be about 20
- Ample time will be provided during and after the special sessions
for interaction between participants. The discussion will be aimed at
a joint representation of knowledge and method, and on a synthesis of
A panel at a joint plenary session will summarize the main findings
and problems generated by the Challenge.
- A plan for a joint publication will be drafted at the conference,
with each author's role defined. Joint publication will put all
discoveries in a unified perspective.
Submitted papers should be in English and not exceed 6 single-spaced pages.
Use 10pt font, the printed area being 22.5cm (9in) height and 16.3cm (6.5in)
width in the center of each page; pages not numbered. The paper must be
submitted to Petr Berka by August 9th, 1999. We prefer electronic submission of
PostScript files by e-mail
or using the “submit contribution” option from the PKDD’99 Web homepage.
contributions will be
published in a technical report of the University of Economics.
