Web Interface for a Database of Events
Hanzlík, Tomáš ; Křivka, Zbyněk (referee) ; Burget, Radek (advisor)
This work includes the design and implementation of a web application that serves as an interface between users and data aggregated from social networks. In the web interface, an emphasis is placed on displaying large amounts of data and browsing through filters. It consists of the JavaScript client part written in Vue.js and Nuxt.js and the server part of the Django REST framework that serves as a data source.

RDF Repository in PHP
Raška, Jiří ; Chmelař, Petr (referee) ; Burget, Radek (advisor)
This Bachelor Thesis describes a problem of design and implementation a RDF repository in PHP. This thesis solves storing data model RDF in relational database and solves implementation of subset query language SPARQL. Part of this thesis are performance and functional tests with implemented RDF repository.

Secure Semantically-Based Discovery of Resources in RESTful Architecutre
Koudelka, Jiří ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
This thesis looks into the problematics of secure semantically-based discovery of resources in REST-ful architecture. The subject of this thesis is the implementation and potential extension of the mRDP for secure discovery of resources in REST-ful architecture, including the implementation of a corresponding open-source library compatible with the Android operating system. Another topic of this thesis is the implementation of simple example applications using this library.

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.

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.

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.

Methods of Information Extraction
Adamček, Adam ; Smrž, Pavel (referee) ; Kouřil, Jan (advisor)
The goal of information extraction is to retrieve relational data from texts written in natural human language. Applications of such obtained information is wide - from text summarization, through ontology creation up to answering questions by QA systems. This work describes design and implementation of a system working in computer cluster which transforms a dump of Wikipedia articles to a set of extracted information that is stored in distributed RDF database with a possibility to query it using created user interface.

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.

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.

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.
