Tool for RDF geodata visualization on a map
Rous, Daniel ; Nečaský, Martin (advisor) ; Škoda, Petr (referee)
The goal of this thesis is to design, implement and test a web application, which will visualize RDF data in a heat map. The heat will be defined by the user's metric data se- lection. The application will simplify user's selection needed for visualization by automatic detection of metric and location data in loaded schema. User will have an opportunity to filter data by some data properties. The application will be tested on two different data sources. One of them will be Central register of grants (IS CEDR III). The other one will be the agenda dataset from Rights and Duties Register (RPP). 1

Searching public transport connections based on transport timetables and individual transport
Matěna, Jakub ; Nečaský, Martin (advisor) ; Kopecký, Michal (referee)
This thesis deals with routing over open data in Prague. Its main purpose is to create server/client based application that makes connection searches combining both public transport and individual car transport. Server provides Protocol buffers \gls{api} that can be used by anyone to create client application for any available platform. Moreover demonstrative client application for Android devices was created as part of this project. All components were tested for usability, functionality and speed. Open data from several sources were used to demonstrate that publishing data can offer new possibilities and that we can achieve complex goals by combining them. It was shown that intermodal planning in Prague is possible and can save time, money and even environment.

Discovering and Creating Relations among CSV Columns Using Linked Data Knowledge Bases
Brodec, Václav ; Nečaský, Martin (advisor) ; Svoboda, Martin (referee)
A large amount of data produced by governmental organizations is accessible in the form of tables encoded as CSV files. Semantic table interpretation (STI) strives to transform them into linked data in order to make them more useful. As significant portion of the tabular data is of statistical nature, and therefore comprises predominantly of numeric values, it is paramount to possess effective means for interpreting relations between the entities and their numeric properties as captured in the tables. As the current general-purpose STI tools infer the annotations of the columns almost exclusively from numeric objects of RDF triples already present in the linked data knowledge bases, they are unable to handle unknown input values. This leaves them with weak evidence for their suggestions. On the other hand, known techniques focusing on the numeric values also have their downsides. Either their background knowledge representation is built in a top-down manner from general knowledge bases, which do not reflect the domain of input and in turn do not contain the values in a recognizable form. Or they do not make use of context provided by the general STI tools. This causes them to mismatch annotations of columns consisting from similar values, but of entirely different meaning. This thesis addresses the...

Sociologická a urbanistická analýza města použitím dat mobilních operátorů, použito na případové studii města Brna
Horáková, Eva
Daily movement patterns of inhabitants derived from mobile phone data are one of very valuable data sources for today’s sociological and urban analyses of modern cities. These data sets are open but – while being of a limited quality – available on a mobile provider’s website. This data enables a number of users in selected areas to be observed through two-hour time slots. It also provides anonymous information about the age and gender of the users. The aim of this paper is to introduce mobile phone data visualisations through a case study of the city of Brno, Czech Republic.

Blend and deblend Linked open data in a Consortium
Pallarès, Jordi
Working in a Consortium give us the perspective to see the benefits of blending ideas to create a applications from a central data/point. In some cases we found the Institution want to deblend or „not blend“ with the consortium and prefer or they see more benefits to made his own aplication. We explain our experience in the Consortium blending and not blending desicions and explain two projects in linked open data to show examples of this two ways. One project We blend all the authorities and in other we not blend in the case of Thesaurus of the University of Barcelona using Skos format.

Potenciál využití otevřených dat v městském plánování
Horáková, Eva
Open data are collected by public institutions and freely distributed online in computer readible format. This enable third parties to further use data for various appllications or participatory processes in the city. Which cities had already joined the open data concept and what kind of information they mostly open? This paper brings an overview to open data situation in Czech and Slovak cities.

Využití otevřených dat při poskytování pomoci v rozvojových zemích při krizových situacích na příkladu Haiti
Krevňáková, Hana
The aim of this thesis is the usage of open data in assisting developing countries in crisis situations based on the example of Haiti. The thesis is based on literal background research of specialized publications, the first section is focused on defining basic theories of open data like conditions, significance, advantages, risks and historical background. After that there are described the best knows licenses without which open data could not be operated and applications, which are very important for organisations and community. There is also an evaluation of the current situation in the world, how the countries access to open data. Significant part is dedicated to the analysis using the open data on the example of Latin American developing country Haiti, where the earthquake occured in 2010. Bachelor thesis examines the usefulness efect of open data.

Creation of a publication plan in the field of science and research
Smetana, Tomáš ; Chlapek, Dušan (advisor) ; Kučera, Jan (referee)
This thesis focuses on the topic of open data, especially in the field of science and research. The work is defined by six sub-targets and characterize the area of science and research in the Czech Republic and abroad, to characterize the issue of open data in the Czech Republic and in the world, describe the method of publication of data on the promotion of science and research in the Czech Republic and in the world, how to propose a procedure and create publications plan for TA CR, prepare a sample dataset, and then evaluate the procedure used. The work is divided into thematic blocks, which are based on these goals. It consists of an introduction, theoretical part, practical part and conclusion. The introductory section defines the objectives of work and research resources devoted to similar topics. The theoretical part describes the problems of science and the problem of open data in the Czech Republic and other countries, and also the process of creating publication plan according to the chosen methodology. The practical part contains according to the targets two parts, one is the analysis of open data of science and research and other preparation publication plan TA CR. The practical part ends with evaluation of procedure used with proposals for improvement. The conclusion contains a summary of the work and evaluate the goals achieved.

Data journalism and its contemporary use
Indra, Jan ; Čermák, Miloš (advisor) ; Jirků, Jan (referee)
The rapid development of technology in the last decades caused an extreme growth in the amount of available information. We live in an era, where information whirls around us almost all the time, thus it is becoming increasingly difficult to have a clear notion about the world and keep track of what is going on. Media realise this development and they are forced to react. One of such reactions is the emergence of a new trend in journalism called data journalism. "Data-driven journalism" is principally based on thorough and critical analysis of various amounts and types of data, and its goal is to reveal new insights. Insights about data which might be key for complex understanding of social phenomena in the 21st century. This paper presents data journalism as a unique field of journalistic work, it defines data journalism and describes some of the processes that lead to creating its output. The practical part of the paper presents its own data journalism project, which attempts for an original analysis and visualisation of the Czech Trade Inspection open data sources.
