This volume contains articles accepted for presentation during The
Intelligent Information Systems Symposium I1S'2000 which was held in
Bystra, Poland, on June 12-16, 2000. This is ninth, in the order,
symposium organized by the Institute of Computer Science of Polish
Academy of Sciences and devoted to new trends in (broadly understood)
Artificial Intelligence. The idea of organizing such meetings dates back
to 1992. Our main in- tention guided the first, rather small-audience,
workshop in the series was to resume the results gained in Polish
scientific centers as well as contrast them with the research performed
by Polish scientists working at the uni- versities in Europe and USA.
This idea proved to be attractive enough that we decided to continue
such meetings. As the years went by, the workshops has transformed into
regular symposia devoted to such fields like Machine Learning, Knowledge
Discovery, Natural Language Processing, Knowledge Based Systems and
Reasoning, and Soft Computing (Le. Fuzzy and Rough Sets, Bayesian
Networks, Neural Networks and Evolutionary Algorithms). At present,
about 50 papers prepared by researches from Poland and other countries
are usually presented. Besides, for several years now, the symposia are
accompanied by a number of tutorials, given by the outstanding
scientists in their domain. Up to this year the proceedings were
published as our local publication and they were distributed among the
scientific libraries. We feel however, that the subject matter as well
as the quality of papers is sufficient to present the proceedings to a
broader scientific audience.
