Genealogic Semantic Wiki
Brychová, Jana ; Smrž, Pavel (referee) ; Schmidt, Marek (advisor)
This thesis project is about possibilities of storing genealogic data in different formats and based on the results it suggests data format which can be used consequently as a source for the vizualization by semantic web. In the scope of the project there is a genealogic application implemented for KiWi platform. This application enable visualization of designed format using prefuse technology. There are basic and aslo some other usefull information about the basic technologies of the semantic web like RDF, XM, ontology, OWL language stated in the document.

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.

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.

Transformation of Web Applications into Web Services
Zámečník, Miroslav ; Rychlý, Marek (referee) ; Weiss, Petr (advisor)
Present web is aiming to the possibility of automatization of user behavior on web applications. Adding of semantics and creation of web service interface are the main approaches for accomplishment of this user comfort. Nevertheless, this direction brings some problems which can make more difficult publishing and implementation of web documents. Web services can connect heterogeneous systems, because they are based on XML markup language that is a place where all applications can meet without lost of platform independence. The automatic transformation of a web application into a web service could be considerably more effective than to create a web service from the beginning. However, this step is for some applications almost unreal without knowledge of their inner structure. In most cases, the transformation will be done semiautomatically with help of human decisions.

Ontology-Based Data Sharing among Information Systems
Hák, Lukáš ; Květoňová, Šárka (referee) ; Burget, Radek (advisor)
This thesis describes data sharing between information systems based on ontologies. In the first chapter shows up the term ontology and used terminology. Then this thesis analyses used basic methods, onthological languages and partially describes semantic web. In the third chapter are write out utilities and plugins which are used for working with ontologies. The other chapters describe created ontology which are useful for car-selling. Especially ontology with cars, sellers and addresses . At the end of the thesis is explained suggested instrument to transfer existing XML to recording advertising in OWL language.

Comparison of RDF Databases
Chatrný, Jakub ; Burget, Radek (referee) ; Milička, Martin (advisor)
The goal of this thesis is compare of several RDF stores Blazegraph, Jena TDB and Stardog. Design of test suites is based on existings benchmarks. In the designed test suites are monitored execution time and number of results. The testing criteria of stores also include the time required to create persistent store and its size. All tested stores and the program for testing itself are implemented in Java.

Vizualizace ontologií na sémantickém webu
Dudáš, Marek ; Zamazal, Ondřej (advisor) ; Vacura, Miroslav (referee)
For ontology development, sharing and usage, availability of a suitable visualization method is essential. Much research has been done in this area, but an ideal method is still missing. One of the reasons might be that most of the available tools offer a general visualization but various use cases require specific approaches to the visualization. This master thesis gives a general overview of current visualization methods and their implementations. Both the methods and specific visualization tools are evaluated from the perspective of several possible use case categories. Special focus is given on visualization of ontology transformations. As none of the available implementations is suitable for this use case as is, an alternative approach is proposed. This approach is based on using several existing visualization implementations together and allowing switching between them using a zoom-like function. It is experimentally implemented as a Protégé plugin.

Ontology-Driven Self-Organization of Politically Engaged Social Groups
Belák, Václav ; Svátek, Vojtěch (advisor) ; Nováček, Vít (referee)
This thesis deals with the use of knowledge technologies in support of self-organization of people with joint political goals. It first provides a theoretical background for a development of a social-semantic system intended to support self-organization and then it applies this background in the development of a core ontology and algorithms for support of self-organization of people. It also presents a design and implementation of a proof-of-concept social-semantic web application that has been built to test our research. The application stores all data in an RDF store and represents them using the core ontology. Descriptions of content are disambiguated using the WordNet thesaurus. Emerging politically engaged groups can establish themselves into local political initiatives, NGOs, or even new political parties. Therefore, the system may help people easily participate on solutions of issues which are influencing them.

Conversion between Topic Maps and RDF/OWL
Kouba, Daniel ; Svátek, Vojtěch (advisor) ; Kosek, Jiří (referee)
Cílem této práce je nastínit princip transformace mezi RDF/OWL a Topic Maps (a obráceně) a zhodnotit použitelnost existujících nástrojů, které konverzi umožňují. Tato práce navíc poskytuje stručný, ale komplexní přehled technologií RDF a Topic Maps. Názorně ukazuje princip obou modelů, shrnuje výhody a rozdíly mezi modely, principy možné transformace mezi modely a popis nástrojů, které konverzi umožňují. Rovněž se snaží zhodnotit kvalitu konverze a míru zachování informací ve výsledném modelu. Navíc se práce zabývá historií obou standardů, a snaží se nastínit i jejich budoucnost. Práce se lehce zabývá i dotazovacími jazyky pro oba formáty. Práce je rozdělena na kapitoly, které se postupně zabývají klíčovými tématy a to RDF, Topic Maps, rozdíly mezi rodinami standardů, princip vzájemné konverze a nakonec kapitoly, která se týká samotných nástrojů pro konverzi. Princip vzájemné transformace je převzat od Garshol L. Přínosem této práce je přehledné shrnutí hlavních technologií, pojmů, rozdílů, faktů a zajímavostí v jednom dokumentu. Po přečtení prvních 4 kapitol by se měl v tomto oboru zorientovat i naprostý začátečník. V závěru práce jsou zhodnoceny nástroje pro konverzi mezi formáty.

Semantic Web Services
Kmoníček, Ondřej ; Brabec, Tomáš (advisor) ; Hejtmánek, Jakub (referee)
Práce se v praktické části zabívá analýzou procesů a popisem fiktivní Webové Služby, která má najít a uzavřít nejlepší stavební spořenní zapsaných v OWL-S. Teoretická část popisuje principy sémantického webu a některé jeho technologie. Podává částečný úvod do webových služeb a propojení principů sémantického webu a webových služeb. To znamená sématické webové služby.
