Text data clustering algorithms
Sedláček, Josef ; Burget, Radim (referee) ; Karásek, Jan (advisor)
The thesis deals with text mining. It describes the theory of text document clustering as well as algorithms used for clustering. This theory serves as a basis for developing an application for clustering text data. The application is developed in Java programming language and contains three methods used for clustering. The user can choose which method will be used for clustering the collection of documents. The implemented methods are K medoids, BiSec K medoids, and SOM (self-organization maps). The application also includes a validation set, which was specially created for the diploma thesis and it is used for testing the algorithms. Finally, the algorithms are compared according to obtained results.

The development and position of small and medium-sized enterprises in the Czech Republic
Sedláček, Josef ; Dočkal, Dalibor (advisor) ; Vebrová, Ludmila (referee)
Small and medium-sized enterprises are gaining more attention from the European Commission and the Government of Czech Republic. Not only because of the current economic crisis, which didn't spare these businesses, but mainly because they are the backbone of the European economy and provide with many jobs. This thesis deals with the development and position of small and medium-sized enterprises in the Czech Republic. The aim is to determine their role in the Czech market from measures like a share of GDP and employment. This thesis also seeks to highlight some opportunities and threats for small and medium enterprises. The first theoretical part focuses on the defini-tion of such enterprises in the Czech Republic and the European Union and consequent-ly continues with the history of small and medium enterprises in the country. The practical part deals with data analysis from the Czech Statistical Office and the Ministry of Industry and Trade. The results of this analysis are to be compared with selected Eu-ropean Union member states. In the conclusion I recommend some measures to improve the position of small and medium-sized enterprises on the Czech market.
