Association Rules Mining over Data Warehouses
Hlavička, Ladislav ; Chmelař, Petr (referee) ; Stryka, Lukáš (advisor)
This thesis deals with association rules mining over data warehouses. In the first part the reader will be familiarized with terms like knowledge discovery in databases and data mining. The following part of the work deals with data warehouses. Further the association analysis, the association rules, their types and mining possibilities are described. The architecture of Microsoft SQL Server and its tools for working with data warehouses are presented. The rest of the thesis includes description and analysis of the Star-miner algorithm, design, implementation and testing of the application.

Methods for Mining Association Rules from Data
Uhlíř, Martin ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
The aim of this thesis is to implement Multipass-Apriori method for mining association rules from text data. After the introduction to the field of knowledge discovery, the specific aspects of text mining are mentioned. In the mining process, preprocessing is a very important problem, use of stemming and stop words dictionary is necessary in this case. Next part of thesis deals with meaning, usage and generating of association rules. The main part is focused on the description of Multipass-Apriori method, which was implemented. On the ground of executed tests the most optimal way of dividing partitions was set and also the best way of sorting the itemsets. As a part of testing, Multipass-Apriori method was compared with Apriori method.

Mining Multiple Level Association Rules
Nachtnebl, Viktor ; Stryka, Lukáš (referee) ; Bartík, Vladimír (advisor)
Knowledge discovery from data scope is quite a young concept but is becoming more and more popular. This bachelor's thesis is engaged in mining multiple level association rules. There are four different methods of investigation discussed. These offer an insight into the problem of concept and implementation of application. At the end we have confronted and reviewed the results of these four algorithms.
