Graph data visualizations with D3.js libraries
Vancák, Vladislav ; Nečaský, Martin (advisor) ; Helmich, Jiří (referee)
Data visualisations help us process large volumes of complex data faster. The goal of this thesis is to implement visualizer plugins into the Linked Pipes Visualization Assistant - a platform for visualising graph data pub- lished in the RDF format. The Assistant automatically analyses data sources and matches them against available visualizers to create interactive views. All visualizers allow configuring the visualisation, saving the configuration and publishing created views. The first group of visualizers works with time- oriented data, viewing instants and intervals on a timeline chart. The second group of visualizers views map-oriented data on the Google Maps. Resources with coordinates are visualised using markers, while resources with coordi- nates and quantifiers are shown as circles (the circle radius corresponds to the quantifier). 1

Cloud database for soil information
Andreeva, Olga ; Nečaský, Martin (advisor) ; Tůma, Petr (referee)
Title: Cloud database for soil information Author: Olga Andreeva Department: Department of Software Engineering Supervisor: doc. Mgr. Martin Nečaský, Ph.D., Department of Software Engi- neering Abstract: The mere presence of scientific data is not enough. Reliable storage and ease of publication critically contribute to the data's usefulness. The Africa Soil Information Service's mission is to describe and understand Africa's soil and landscape resources. To ensure its accomplishment the introduc- tion of modern information technologies is essential - they provide the necessary means to safely store, easily share and analyse the information collected from soil samples and drone imagery. In the presented work we develop a system that will tackle one part of the problem - how to store the information extracted from soil samples. The current method that is employed by scientists consists of making a record on paper by hand in one of the books in the laboratory's storage room. Such system, of course, does not allow to easily share the data, it is prone to damages (e.g. in case of _re) and leaves little room for analysis (especially using methods from machine learning, which require a large set of digital data). By contrast our system, developed in the form of a web application, stores soil information in the...

Presentation layer and interface for a system for information integration and search
Hladík, Tomáš ; Nečaský, Martin (advisor) ; Peška, Ladislav (referee)
The aim of this thesis is to analyse, design and implement a system to present business objects. These objects are accessible through an existing RESTful API of an integration system. The system combines various sources and publishes them together with information how these data are stored. The task of the thesis is to create data views that meet the following requirements - they can react to metadata changes, they support multiple output formats and these views can be customized. The application should be easily modifiable and connectable to already existing web systems.

Web System for Crowdfunding Based on Selling Items with Custom Imprint
Škvařil, Jan ; Parízek, Pavel (advisor) ; Nečaský, Martin (referee)
The aim of this thesis was to design and implement a web system for organization of crowdfunding campaigns that are based on the sale of items with custom imprint. The implemented system automates and facilitates the whole campaign lifecycle from the design of the imprint in an integrated editor through campaign evaluation up to the distribution of final products to customers. Therefore, there is a minimum number of points where the administrator's action is required. Part of the implementation was also seamless integration with external services like on-line payments, printing house, and social networks. Powered by TCPDF (www.tcpdf.org)

Visual knowledge graph management tool
Woska, Aleš ; Nečaský, Martin (advisor) ; Helmich, Jiří (referee)
Linked data are usually visualized as graph structures which are useful for browsing resources but less useful for viewing structured data. This thesis proposes a solution how to visualize linked data in a tabular structure. The goal of the visualization is to make an orientation in data easier for a user. A tabular structure for specific data can be designed and managed in a graphic editor. Visualized data can be checked for errors and can be edited to obtain a script which fixes them.

Education app for kids
Kuklisová, Anikó ; Kofroň, Jan (advisor) ; Nečaský, Martin (referee)
The goal of this thesis was to create an educational application for children in elementary schools which is easy to use both for children and teachers. Nowadays there are lots of similar applications, but most of them support only the English language. Our target users are primarily Czech students. The main advantage of the application is that it does not focus on a single subject. It includes modules in which one we can practice maths, grammar, writing or music education. The most important feature of the application is its extendability, which includes adding modules and examples at the user level. The thesis consists of two applications. The main application has an educational character. The second application manages the database on the FTP server. Powered by TCPDF (www.tcpdf.org)

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)

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.

Mobile application Drug Encyclopedia
Lisý, Marek ; Nečaský, Martin (advisor) ; Kopecký, Michal (referee)
The goal of this work is to design and implement a mobile application for Android operating system allowing simple searching and displaying drug information for common patients. All data comes from publicly available sources. The work includes the development of the mobile client user interface as well as the server side providing data. The primary source of the data for the server side is an integrated drug data from various publicly available sources represented in form of Linked Data and accessible via SPARQL endpoint.
