Semantic Annotation of Text
Dytrych, Jaroslav ; Svátek, Vojtěch (referee) ; Šaloun, Petr (referee) ; Smrž, Pavel (advisor)
This thesis deals with intelligent systems for support of the semantic annotation of text. It discusses the motivation for creation of such systems and state of the art in the areas of their usage. The thesis also describes newly proposed and realised annotation system which realizes advanced functions of semantic filtering and presentation of annotation suggestion alternatives in a unique way. The results of finished experiments clearly show the advantages of proposed solution. They also prove that the user interface of the annotation tools affects the annotation process. The optimisation of displayed information for the task of disambiguation of ambiguous entity names was done and proposed methods to speedup and increase of quality of the created annotations was experimentally evaluated. The comparison with the Protégé general tool has proven the benefits of created system for collaborative ontology creation which should be anchored in the text. In the conclusion, all achieved results are analysed and summarized.

Automatic Creation of Dictionaries from Translations
Svoboda, František ; Matějka, Pavel (referee) ; Smrž, Pavel (advisor)
Goal of this thesis is to implement system, capable of extracting bilingual dictionaries from parallel texts. Reader may find examples of how to obtain such documents and description of steps leading to successfull acquirement of desired information. Mainly statistical machine translation methods were examined and used for this purpose. Besides description of created system, short analysis of problems linked with the subject can be found as well as evaluation of results.

Methods for class prediction with high-dimensional gene expression data
Šilhavá, Jana ; Matula, Petr (referee) ; Železný, Filip (referee) ; Smrž, Pavel (advisor)
Dizertační práce se zabývá predikcí vysokodimenzionálních dat genových expresí. Množství dostupných genomických dat významně vzrostlo v průběhu posledního desetiletí. Kombinování dat genových expresí s dalšími daty nachází uplatnění v mnoha oblastech. Například v klinickém řízení rakoviny (clinical cancer management) může přispět k přesnějšímu určení prognózy nemocí. Hlavní část této dizertační práce je zaměřena na kombinování dat genových expresí a klinických dat. Používáme logistické regresní modely vytvořené prostřednictvím různých regularizačních technik. Generalizované lineární modely umožňují kombinování modelů s různou strukturou dat. V dizertační práci je ukázáno, že kombinování modelu dat genových expresí a klinických dat může vést ke zpřesnění výsledku predikce oproti vytvoření modelu pouze z dat genových expresí nebo klinických dat. Navrhované postupy přitom nejsou výpočetně náročné. Testování je provedeno nejprve se simulovanými datovými sadami v různých nastaveních a následně s~reálnými srovnávacími daty. Také se zde zabýváme určením přídavné hodnoty microarray dat. Dizertační práce obsahuje porovnání příznaků vybraných pomocí klasifikátoru genových expresí na pěti různých sadách dat týkajících se rakoviny prsu. Navrhujeme také postup výběru příznaků, který kombinuje data genových expresí a znalosti z genových ontologií.

Support for Codenames Game on Mobile Phone with OS Android
Grossmann, Jan ; Fajčík, Martin (referee) ; Smrž, Pavel (advisor)
This bachelor's thesis deals with creation of an application for support for the Codenames game on mobile phone with Android operating system. Application helps user with game strategy and simplify selection of the clue. First I discuss existing solutions and their imperfections. Based on this experience, I analyze designed solution and then, the very implementation with usage of Java programming language, involving storing data with database system or optical recognition. Finally, I undertake user testing, which I also describe in detail.

Application for Parallel Data Processing Control
Grepl, Filip ; Smrž, Pavel (referee) ; Dytrych, Jaroslav (advisor)
This work deals with the design and implementation of a system for parallel execution of tasks in the Knowledge Technology Research Group. The goal is to create a web application that allows to control their processing and monitor runs of these tasks including the use of system resources. The work first analyzes the current method of parallel data processing and the shortcomings of this solution. Then the work describes the existing tools including the problems that their test deployment revealed. Based on this knowledge, the requirements for a new application are defined and the design of the entire system is created. After that the selected parts of implementation and the way of the whole system testing is described together with the comparison of the efficiency with the original system.

Planning and Reporting Work in the KNOTIS Information System
Fiedler, Karel ; Smrž, Pavel (referee) ; Dytrych, Jaroslav (advisor)
The aim of this thesis is creation of new module for planning and reporting work in the information system KNOTIS and editation of another pages related with this module. New module compared to old one will support planning for individual projects and prioritization of important projects as a bachelor's thesis. Reward payment is extended by the possibility to calculate the amount according to salary and hours and also supports pre-filling of the salary of the new reward payment. For work plans, the maximum weekly workload can be set according to the period.

Automatic Generator of Diacritics
Veselý, Lukáš ; Sumec, Stanislav (referee) ; Smrž, Pavel (advisor)
The goal of this diploma work is the suggestion and the implementation of the application, which allows adding / removing of diacritics into / from Czech written text. Retrieval "trie" structure is described along with its relation to finite state automata. Further, algorithm for minimization of finite state automata is described and various methods for adding diacritics are discussed. In practical part the implementation in Java programming language with usage of object-oriented approach is given. Achieved results are evaluated and analysed in the conclusion.

Extending Functionality of European Project Portal
Vorobiev, Nikolaj ; Doležal, Jan (referee) ; Smrž, Pavel (advisor)
This thesis is based on 2 previous theses, complements and expands the last of them. The primary objective is to take existing source files, study, modify and use them for the purpose of running and updating the system. It is a necessary intermediate step, which the previous thesis solved partly. The secondary objective is to expand the system focused on improving the navigation, creating relations between the similar existing system entities, metasearching for relevant resources according to user requirements, extracting and storing new unique information about entities in the system, which is not provided by the current source. The result of the thesis is a running system, filled with fresh data, prepared and improved for system users. The source code of the system is refactored, became more readable and is ready to be extended. The metasearch engine is created, in modern Perl 5. The source code of the engine is portable and scalable, which allows easy integration into other systems.
