Transformations of Ontologies
Kopecký, Marek ; Škoda, Petr (referee) ; Dytrych, Jaroslav (advisor)
This master's thesis describes importing the ontology in language OWL 2 into the internal structures of 4A annotation server. It is concerned in anonymous nodes, for example in anonymous classes or anonymous properties. The solution was to use the library The OWL API for import ontology. The solution also allows automatic generation of names to anonymous classes and properties.

Utilization of Knowledge Systems and Bases for Selection and Evaluation of Domestic Electrical Installations.
Haluza, Miroslav ; Martínek, Zbyněk (referee) ; Gurecký, Jiří (referee) ; Toman, Petr (advisor)
My doctoral thesis deals with use of the sophisticated methods for the selection of technical and economic solution of electrical wiring. This solution is based not only on a price but also on many other criteria such as a comfort, service, durability etc. The focus of the work is a treatise on wiring systems from a global perspective, where it is impossible to use a conventional approach for objective evaluation and selection of the appropriate electrical wiring system (because of the complexity of such systems and their interdependencies). In the four chapter are given information of an energy consumption (the total consumption and household consumption). In this chapter is given also a consumption prediction – especially for households. Following is an overview of possible measures for reducing electricity consumption in households. In the next part of this thesis are solved the knowledge, respectively expert systems for use in an electrical engineering – especially for a suitable tool for the selection and evaluation of households wiring electrical system. The result of this work provides a possible solution for a selection of wiring electrical system for households (focusing on the intelligent wiring) – from a technical and economic point of view and with using an innovative approach. The main contribution of this work is a proposal of the main part of the knowledge base. This base could be as a basis for knowledge, respectively for an evaluating technical and economical solution of an electrical wiring system – the expert system includes also a feedback function of an effectiveness solution, use value, price etc., which would also serve as a knowledge base.

Ontology-Based Content Management System
Čekan, Ondřej ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
This thesis deals with the analysis, design and implementation of a system based on semantic technologies and ontology languages. There is described the semantic web and its concept, technology of semantic web especially RDF and OWL and the ability to view on the Web. Another part of this work treats with the specification, analysis, design actual implementation of the system, which processes the ontology and allows users to create individual depending on the definition of the ontology. The created content is presented on the Web annotated. The result of this work is the demonstration application.

Graphical User Interface for Comparing RDF Models
Krčmář, Martin ; Šilhavá, Jana (referee) ; Smrž, Pavel (advisor)
Práce se zabývá vizualizací rozdílu mezi dvěma RDF modely. Jsou zde porovnávány existující nástroje a postupy, tyto nástroje jsou rozděleny do dvou kategorií. První kategorie reprezentuje textový přístup k zobrazování ontologií a potažmo jejich rozdílu, druhá zastupuje grafické metody. Na základě jejich zkoumání je navržen nový přístup. Konkrétně se jedná o nástroj, který podporuje paralelní textovou reprezentaci ontologií, která je obohacena o sémantické anotace (delta tags)

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.

Ontology and Semantic Web
Stuchlík, Radek ; Hruška, Tomáš (referee) ; Očenášek, Pavel (advisor)
The purpose of the master's thesis "Ontology and Semantic Web" is to give a description of general principles of ontologies, which are closely associated with so-called new generation of web: semantic web. The thesis is conceived as tutorial and it is focused on both theoretical basics and practical examples of the use of technologies developed recently. The aim of this tutorial is to present main ideas of semantic web, technologies and data formats, which should provide its implementation into standard practice.

Text Classification Methods in the Context of Web Pages
Trstenský, Patrik ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
This work deals with the issue of text classification in the context of websites. It examines available classification methods and their accuracy over web page plain text. It deals with constructing a dataset for training these methods for a specific domain. We obtain data for creating the dataset from publicly available websites that utilize RDF documents defined in HTML code. The conclusion of the work consists of the creation of two datasets for two different domains. Furthermore, the use of these datasets for training models and testing of their accuracy.

Využití propojených otevřených dat skrze webová API
HELLER, Dominik
This bachelor thesis focuses on the topic of linked open data utilization by the means of application programming interface of representational state transfer architectural style. The main goal of the thesis is to analyse the current state of the field in regards to semantic web technologies and their relations to more traditional approaches to data publication and extraction. More precisely the proposed goal is to formulate a programming solution which would allow to publish, consume and manipulate the semantic data, otherwise accessible only via SPARQL endpoints, in very well-known and notably convenient way.

Semantic annotation of domain dependent data
Fišer, Dominik ; Vojtáš, Peter (advisor) ; Kopecký, Michal (referee)
One of the problems of semantic web is automated getting annotated data - web pages. Therefore this work is engaged in manual annotation of web pages and try to simplify this process for users using proposed methods. First part contains analysis of annotated data, users and vocabularies used for annotation. Afterwards are proposed methods which simplify annotation creation for users, the possibility of usage similar annotations or possibility highlight interesting parts of web page suitable for annotation. The work includes proposal of annotation tool user interface also that verifies proposed methods in practice. On the basis of this proposal was created a prototype implementation of the annotation tool Semantic Annotator as an extension for Google Chrome browser, which was also used for experiment verifying user-friendliness especially.
