Comparation of Models for Datamining
Pospíšil, Jan ; Bartík, Vladimír (referee) ; Lukáš, Roman (advisor)
This thesis focuses on comparing of the datamining models features depending on the different databazis topology. The objekt was to find key features that at most involve the accuracy of classification. Thesis is composed from chapters in a way that even a non-professional or even a complete laik could understand the object and could find theese thesis results useful. In the beginning the reader is beeing made familiar with all the background information about datamining and its models and algorithms, the second part denotes about the model comparison and discusses its results.

Datamining in data from financial institution
Fedorko, Michal ; Rauch, Jan (advisor) ; Kotlář, Ondřej (referee)
The main purpose of this paper is to create datamining analysys of volutary termations in financial institution based in Czech republic on the data stored by HR department. Only hard data currently stored was input. For creating analysys the CRISP-DM metodology was used. For modeling itself the LISp-Miner was used. Association rules were the main approach to solving the task..Several interesting association rules were found and interprated. Outcome of the paper is for internal campains of the customer and there is even motivation for furthure predictive modeling and this was the first step.

Datamining on publicly accessible data
Pangrác, Jiří ; Rauch, Jan (advisor) ; Chudán, David (referee)
This bachelor thesis deals with the datamining methods on publicly accessible data. Data mining is a technique of mining potentially interesting relations from data. Analysis is carried out on data provided by Česká obchodní inspekce, the czech office for trade inspection, which are accessible to public. I am trying to find possible answers for some analytical questions asked. For the analysis itself, LISp-Miner system was used focusing on 4ft-Miner and CF-Miner procedures. Besides the actual analysis, this thesis includes a brief description of LISp-Miner system and datamining generally. The main goal of this work is presentation of the results for their possible practical use.

Mapping of PMML and BKEF documents using PHP in the SEWEBAR CMS
Vojíř, Stanislav ; Kliegr, Tomáš (advisor) ; Zamazal, Ondřej (referee)
In the data mining process, it is necessary to prepare the source dataset - for example, to select the cutting or grouping of continuous data attributes etc. and use the knowledge from the problem area. Such a preparation process can be guided by background (domain) knowledge obtained from experts. In the SEWEBAR project, we collect the knowledge from experts in a rich XML-based representation language, called BKEF, using a dedicated editor, and save into the database of our custom-tailored (Joomla!-based) CMS system. Data mining tools are then able to generate, from this dataset, mining models represented in the standardized PMML format. It is then necessary to map a particular column (attribute) from the dataset (in PMML) to a relevant 'metaattribute' of the BKEF representation. This specific type of schema mapping problem is addressed in my thesis in terms of algorithms for automatic suggestion of mapping of columns to metaattributes and from values of these columns to BKEF 'metafields'. Manual corrections of this mapping by the user are also supported. The implementation is based on the PHP language and then it was tested on datasets with information about courses taught in 5 universities in the U.S.A. from Illinois Semantic Integration Archive. On this datasets, the auto-mapping suggestion process archieved the precision about 70% and recall about 77% on unknown columns, but when mapping the previously user-mapped data (using implemented learning module), the recall is between 90% and 100%.

Testování softwarového systému Ferda pro dobývání znalostí z databází
Moulis, Martin ; Rauch, Jan (advisor) ; Ralbovský, Martin (referee)
Základním cílem práce je otestovat softwarový produkt Ferda Data Miner a srovnat jej se systémem 4ft Miner. Po vytvoření vlastního souboru testovacích úloh byla provedena měření počtu vydaných hypotéz, počtu verifikací a rychlosti programu Ferda. Výsledky měření ukazují na nesrovnalosti v počtu nalezených hypotéz a výrazně nižší rychlost systému Ferda ve srovnání s 4ft Minerem. Závěr práce obsahuje shrnutí výsledků a doporučení, kterým směrem by mělo pokračovat případné další testování.
