Data mining from switchboard
BUMBA, Tomáš
Nowadays is the system performance of computing systems on such a sufficient level, so there are stored up large databases, but those are useless without using proper software tools. One of those computing systems is as well a central switchboard and its database will be scanned. It consists of hundreds of phone calls, realized throught switchboard, within and without company´s area. The target of following thesis is to discover unapparent relations in the database of central switchboard. And institute those relations into patterns of human relation.

Data Structure Estimation - Rule Based Algorithm
Řimnáč, Martin
The data structure estimation may provide a connection between the semantic web vision and currently used web sources containing no semantic description of presented information. It enables information from web pages to be processed by semantic web tools with the best to be known about these sources, with the source estimated data structure. The paper gives a method description and presents its usage for a inductive logic programming task. The advantages of a rule-based system usage is given as well.

ECML/PKDD konference - výzva k analýze dat o rizikových faktorech aterosklerózy
Berka, P. ; Tomečková, Marie ; Rauch, J.
It becomes a good habit to organize a data mining cup, a competition or a challenge at machine learning or data mining conferences. The main idea of the Discovery Challenge organized at the European Conferences on Principles and Practice of Knowledge Discovery in Databases since 1999 was to encourage a collaborative research effort rather than a competition between data miners. Different data sets have been used for the challenges during the six years. The paper summarizes out experience gained when organizing and evaluating the challenge on the atherosclerosis risk factor data.
