Web Interface for Managing RDF Data Sets
Kiss, Tomáš ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
The main aim of this thesis is to provide information about RDF data model. Theoretical part of the thesis represents possible ways of storing RDF data, existing RDF storages and SPARQL query language. Furthermore, there is a brief representation of tools used for creation of client web applications with main focus on the Vue.js framework. Acquired knowledge is used to implement web interface enabling browsing of RDF storage and interactive creation of SPARQL queries.

Web Editor for SPARQL
Paulovič, Daniel ; Hynek, Jiří (referee) ; Burget, Radek (advisor)
Target of this thesis is to create web editor for query language SPARQL as component in javascript framework Vue.js and web application using this component to query over SPARQL endpoints. To implement editor were used CodeMirror library and PrimeVue library for user interface. Final version of component is publicly available as npm package. Benefit of this thesis is easily importable editor with many functions to simplify writing queries.

Web Interface for RDF Storage Browsing
Tomov, Patrik ; Hynek, Jiří (referee) ; Burget, Radek (advisor)
The aim of this thesis is to create a web interface for browsing the RDF storage, where the user will be able to manipulate its content. Within the storage, he will be able to create and delete repositories, add and delete repository content, view and interact with repository content, and also perform SPARQL queries within the repository. The client part of the application is written in Javascript using the Vue framework. The RDF4J server, which is deployed on the Apache Tomcat service, is used for the server part. Communication between the server and the client is secured using the RDF4J REST API. The resulting application allows to interactively and easily browse the content of the RDF storage.

Tool for NDL
Myazina, Elena ; Richta, Karel (advisor) ; Kopecký, Michal (referee)
Title: Tool for NDL Author: Elena Myazina Department: Department of Software Engineering Supervisor: Doc. Ing. Karel Richta, CSc. Supervisor's Supervisor's e-mail address: richta@ksi.ms.mff.cuni.cz Abstrakt: -Current research networks allow end users to build their own application-specific connections (lightpaths) and Optical Private Networks (OPNs). This requires a clear communication between the requesting application and the network. The Network Description Language (NDL) is a vocabulary designed to describe optical networks based on the Resource Description Framework (RDF). These descriptions aid applications in querying the capabilities of the network and allow them to clearly express requests to the network. This work deals with the analysis of the current draft language NDL systems and optical components. He compares its potential and shortcomings of the proposal seeks. It also proposes a graphical representation corresponding to that language, which implements the graphical tool. The developed tool will allow the subsequent dialogs (voice) applications. Key words: NDL, RDF, optical mapping technology.

Tools for NDL Elaboration
Myazina, Elena ; Richta, Karel (advisor) ; Kopecký, Michal (referee)
Title: Tools for NDL Elaboration Author: Bc. Elena Myazina Department: Department of Software Engineering Supervisor of the master thesis: doc. Ing. Karel Richta, CSc., Dept. of Software Engineering, Faculty of Mathematics and Physics, Charles University in Prague Abstract: Current state of research of networks enables end users to create custom connections (lightpaths) for a given application and optical private networks (OPNs). Such adjustments require clear communication between the requesting application and the desired network. Language NDL (Network Description Language) is used to describe such optical networks. NDL is based on the Resource Description Framework (RDF). This thesis analyzes the network description language NDL and its treatment. Current status of the network can be loaded in the form of the description in the NDL and displayed as the graphical representation. The representation enables to find out paths in the network, or edit the network. The result can then be transformed back into NDL format. Keywords: NDL, RDF, optical technology.

Web application for presentation integrated inspection data
Finger, Artur ; Nečaský, Martin (advisor) ; Knap, Tomáš (referee)
An initiative arises across the globe, to publish government data as Linked Data, thus con- necting it to other parts of the semantic web. Together the data forms the Linked Data Cloud, which serves as a rich data source for numerous applications. Overcoming unexpected pro- blems, we managed to convert data about inspections carried out by the State Veterinary Administration into that format. For that we used an ETL tool called UnifiedViews. Resulting data were described using well-known RDF ontologies. Then, also using UV, we integrated this data with Linked Data of the Czech Trade Inspection Authority. We created a web ap- plication, that uses this integrated database to search for fair businesses. Using a database server called Virtuoso, we managed to implement search by geographical coordinates. Our application is extensible by new data sources and extracted SVA data are available as open Linked Data.

Governmental Linked Data and Experimental Application
Pošepný, Tomáš ; Nečaský, Martin (advisor) ; Stárka, Jakub (referee)
The aim of this thesis is to introduce the technologies of Resource Description Framework and Linked Data and map the current situation in pub- lishing procurement in the Czech Republic on the Internet. The thesis is focused on problems and de ciencies in the publishing and o ers solution in the form of Government Linked Data. Along with that, an experimental application for scraping and triplifying public contracts from the E-ZAK system is developed. It also allows possible later extensions for other systems administrating public procurement. The obtained RDF dataset is mashed up with a Linked Data da- ta source for public contracts posted in ISVZ containing also information about organizations from ARES system. The mashed data are visualized in a simple Web application. In the conclusion, the entire thesis is summarized and a couple of hints for developers of similar applications are mentioned.

Customizable Linked Data Browser
Klíma, Karel ; Nečaský, Martin (advisor) ; Klímek, Jakub (referee)
The aim of this thesis is to identify key requirements for exploring Linked Data and design and implement a web application which serves as a Linked Data browser, including search and customization features. In comparison to existing approaches it will enable users to provide templates which define a visual style for presentation of particular types of Linked Data resources. Alternatively, the application can provide other means of altering the presentation of data or the appearance of the application. Powered by TCPDF (www.tcpdf.org)

SPARQL compiler for Bobox
Čermák, Miroslav
The goal of the work is to design and implement a SPARQL compiler for the Bobox system. In addition to lexical and syntactic analysis corresponding to W3C standard for SPARQL language, it performs semantic analysis and optimization of queries. Compiler will constuct an appropriate model for execution in Bobox, that depends on the physical database schema.
