Generating data using the LM Reverse-Miner
Stluka, Jakub ; Šimůnek, Milan (advisor) ; Kliegr, Tomáš (referee)
In past years, great attention has been paid to evolutionary algorithms and they have been utilized in wide range of industries including data mining field, which nowadays presents a highly demanded product for many commercial institutions. Both mentioned topics are combined in this work. Main thesis subject is testing of new Reverse-Miner module, which can generate data with hidden properties using evolutionary algorithms while using also other modules of LISp-Miner system, commonly used for the purposes of data mining. Main goal lies in generation of two databases by the module in such way so they would meet explicitly set requirements. Other goals are also set within the thesis in the form of understanding the domain necessary for subsequent modeling. The result of the practical part of the thesis is represented not only by two successfully generated databases, but also by description of steps, methods and techniques used. The common recommendations for data preparation by module Reverse-Miner are later summarized, based on experience with modeling. Previous thesis outputs are furthermore contemplating the conclusion of analysis of technical means used for generation and they also provide several suggestions for possible future extensions.

Shop with image content
Stluka, Jakub ; Palovský, Radomír (advisor) ; Sklenák, Vilém (referee)
Work is dedicated to electronic image commerce and image content analysis and is focused on the functionality required for such e-shop and its development based on open source tools. The theoretical part contains the principles of world stock libraries and used business models. Then, the work deals with issues of classification and retrieval of content, which analyses the possibility of categorization, text search, tagging, theme issue of synonyms and this topic is completed by the overview of current opportunities in the field of automatic content identification. Next topic covers licensing issues, in which current standard licensing models are examined, followed by the topic of content protection, which aims to protect the photos, while allowing their sale. Last chapter of theoretical work is about payment options, in which the work seeks to evaluate the selected payment methods used in connection with the image bank. Theoretical work is followed by practical work, where online photo bank model is designed and implemented, allowing users to search, buy and upload photos using simple credit transactions. Within the description of the model functions is outlined where and how the model should be extended in case of deployment to real business.
