Design and implementation of an application for students searching for higher education
Phi Viet, Duc ; Zeman, Václav (advisor) ; Dudáš, Marek (referee)
The aim of this bachelor thesis is to design and implement a web application for graduates of secondary schools or bachelor's branches who are looking for follow-up studies. This application allows them to view the database of universities and their programs. The main function of the application is the option of filtering the required data of the programs, such as the required level of language certificates and GMAT values for the admission of the applicant. In the theoretical part, the reader first becomes familiar with the project as such, its main mission and goal, business plan and future vision. He also learns what benefits can this portal bring to him as a user, how they differ from those who compete and why choose it. Based on the collected data, the segments of potential users and customers were analyzed. The practical part should include the design and implementation of application logic according to a valid UML notation, along with the implementation of a graphical user interface prototype including usability testing.

Business rules editor
Duben, Přemysl Václav ; Vojíř, Stanislav (advisor) ; Dudáš, Marek (referee)
The main focus of this Bachelor thesis is on the design and implementation of business rules editor usable in a research project EasyMiner. This editor should help nontechnical expert to create business rules in simplified format of structured language SBVR. To achieve a goal there is used the knowledge of Web Development issue in conjunction with a detailed research of similar tools. Within this thesis are tested two ways of control with a clear appreciation their usability and with suggestion for future development. Benefit of this thesis should be particularly realistic deployment within the infrastructure of EasyMiner project, which is supposed to be a tentative alternative editor of founded association rules that expand the possibilities of association rules data-mining on progressively created knowledge base in business rules format. This thesis is divided into theoretical and analytical-implementation part. In the theoretical part the reader is familiar with the essential requirements, keywords and relations, research of similar tools as well as with literature review. In the second part is focused attention on comprehensive analysis of editor development with a focus on modern standards to achieve the best result.

Design of Data Structures using RDFS/OWL
Horáková, Linda ; Dudáš, Marek (advisor) ; Mynarz, Jindřich (referee)
The main aim of the bachelor thesis is to explore possibilities and advantages of publishing statistical data on Semantic Web according to Linked Data Principles. In theoretical part readers are familiarized with basic features of Semantic Web, principles and options of publishing Linked Data. The thesis is mainly focused on an analysis of existing vocabularies used for description of statistical data, especially in the field of public spending. The outcome of the analysis is the statement that general vocabularies are more suitable for description of statistical data, because they provide wider possibilities than proprietary ontologies. The result of the analysis was verified by the draft concept of data structure describing the field of public spending, which is based on general Data Cube Vocabulary. The practical part of the thesis also contains construction of SPARQL query which can be used for automatic transformation of current data to the shape that is suitable to the new data structure.

Modularization of extraction of public procurement data to RDF
Káňa, Jakub ; Mynarz, Jindřich (advisor) ; Dudáš, Marek (referee)
The bachelor thesis deals with extension of data extractor of public contracts gained from server Tenders Electronic Daily. The thesis covers a modularized extractor 10 new types of public contract notices. The data is retrieved from XML by using transformation scenario and they are extracted to RDF/XML data format. The extension is realized on TED-XML and META-XML formats of published data. The work also expands and creates independent library of functions. The library is documented. To ensure the accuracy of the extracted data in terms of syntax and also used ontologies there are used validation tools. For command line syntax validation Jena Apache Riot and for testing the correctness of output in terms of use Public Contracts Ontology RDFUnit testing tool. The contribution of this work is the practical part, allowing you to convert semi-structured data from the Journal of procurement of EU Member States into a fully structured data. Enhanced extractor allows you to extract data from the notices type F04 - F09 and F15 - F18.

Interactive visualization of XML schemas in internet browser using client's XSLT
Kačina, Peter ; Kosek, Jiří (advisor) ; Dudáš, Marek (referee)
This bachelor thesis is focusing on design and implementation of prototype application, which will be used for transformation from W3C XML schema to visual form in SVG (Scalable Vector Graphics) format. Visualized schema will made easier to understand it and it will be possible to use it as a part of documentation to XML files. It could be also used by developers which will develop XML documents according to the schemas. Visualized form will interpret structure of the document and will provide information about its parts -- elements, complex types and attributes. The goal of the thesis is to create a tool, which will generate interactive graphic in browser with the help of clients XSLT processor -- Saxon CE. In the beginning in the thesis are described used technologies and its way of use in this prototype application. Further in the thesis is described design of graphic model and algorithm and also described how the interactivity is functioning. In description of graphic model are shown pictures of graphic interpretations of each structure mentioned hereinbefore. In following chapter is the algorithm, which main responsibility is to mine data from the source XML document and ensuring of interactivity, described in more detail. Practical output is prototype XSLT transformation, which with the help of clients XSLT processor Saxon CE will transform any W3C XML schema into graphic representation.

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 Transformation Pattern Editor
Dudáš, Marek ; Zamazal, Ondřej (advisor) ; Vacura, Miroslav (referee)
In lifecycle of ontologies -- during their creation, extension and various ways of their usage there may arise a need for changing the current modeling style of the ontology -- for transforming the ontology. Such transformation may be of course done manually, but in case of larger ontologies the process can be quite time consuming and even when transforming smaller ontologies there is a risk of making mistakes. In [1] a collection of software services and framework for automatic or semiautomatic ontology transformation has been introduced. The input for these services is (together with the source ontology which we want to transform) a definition of the transformation called a transformation pattern in a form of an XML (so basically a text) file. As a topic of this bachelor's work I created a Graphical editor of transformation patterns (TP Editor) -- an application that allows creation of transformation patterns in a similar way as UML modeling tools makes software design easier. The application has form of a plugin for Eclipse. This work contains a short introduction into the domain of transformation patterns, a user guide for the plugin and a programmer's guide. The programmers guide contains an introduction into used technology -- the GEF library, description of the source code and suggestions for further development of the plugin.
