Datamining from Jabber
Sendler, Jaroslav ; Šebek, Michal (referee) ; Mlích, Jozef (advisor)
This bachelor's thesis deals with the collection and analysis of data from the network for the Jabber instant messaging. There is a client decsribed that collects data and then stores them in a database. The client performs the function of a robot that responds appropriately to the selected questions. Further information is collected for analysis. For this purpose their transformation was first made, that reflects the temporal characteristics of data. It was subsequently used algorithm k-eans of tool RapidMiner. The results are presented by graphical form and using a spreadsheet.

Mathematical Models of Process Capability
Horník, Petr ; Hübnerová, Zuzana (referee) ; Bednář, Josef (advisor)
Firstly, we deal with the verification of normality and other necessary prerequisites needed in this thesis. We also introduce transformations to converse non-normally distributed data to normal and continue with capability analysis. We describe the design of control charts, useful tools to assess process stability. They help us to eliminate assignable causes and leave only chance causes in process. We obtain process in control state. Finally, we introduce both capability and performance ratios for both normal and non-normal data, and analyse some of their properties. At the end of the thesis, we prove acquired knowledge by performing capability analysis of real process.

Componentization of Linked Data Transformations
Pilař, Štěpán ; Mynarz, Jindřich (advisor) ; Knap, Tomáš (referee)
The diploma thesis is focused on transformation of linked data and opportunities for componentization of extract, transform, load process resulting in reusability of such components. UnifiedViews serves as a framework for demonstration of implementa-tion of selected components. Initial review of related fields of study, relational data oriented ETL and linked data quality management being most prominent, is followed by bottom-up analysis of existing extractors and transformations. Identified common transformations are supplemented by operations known from transformations of relational data. Options and limits of each component candidate are discussed as well as possible cooperation with other components. The next section discusses supported ways of implementation in the selected environment and provides a list of key questions for decision making process is provided. The last part describes implementation of selected components with respect to the approach suggested in the preceding section. Practical use as well as limitations of the implemented components are demonstrated on tasks transforming public contracts datasets.

Difficulty of Preparing Self-Service BI Environment
Píhrt, Tomáš ; Gála, Libor (advisor) ; Pour, Jan (referee)
The aim of this thesis was to evaluate the difficulty of preparing the environment for business intelligence tools, namely self-service which shows a growing potential in this field. Starting point was the analysis of existing methodologies, procedures and recommendations for preparing BI environment, furthermore the analysis of factors that affect the process of preparation. In order to verify the differences between self-service BI products were defined a methodology and criteria which were relevant for evaluation. The evaluation of Top 5 BI products was examined based on the evaluation model and using specific data set from a small business company environment.

Description, analysiss and interpretation as three types and phases of qualitative data transformation
Heller, Daniel
Data description, data analysis, and data interpretation can be understood as three types of data transformation and at the same time as three phases of this transformation. The author compares these three procedures of qualitative data transformation and points to the differences that stem from emphasizing the data description, the data analysis, and the data interpretation. The different approaches can be illustrated by examples from the field of qualitative research. The data transformation is considered to be the superior and key concept.
