Information Retrieval in Text Data
Tkadlčík, Luboš ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
This thesis researches the issue of text data mining and information retrieval. It describes the most common representations of text documents and retrieval strategies. The aim of this thesis is design and implementation of application, which realises information retrieval via vector space model. The application implements three different ways of similarity calculation: cosine measure, the Jaccard coefficient and the Dice coefficient. Achieved results are assessed. Possible continuance of the project is outlined.

Sources of Information Used for Calculating Selected Indicators of Financial Analysis and Their Relevance
Antoš, Milan ; Hejnová, Martina (referee) ; Hanušová, Helena (advisor)
Předmětem diplomové práce je implementace teoretických poznatků s cílem ověřit relevantnost zdrojů informací sloužících pro výpočty ukazatelů finanční analýzy. První část je zaměřena ne teoretické poznatky finanční analýzy zejména u výrobních podniků a služeb. V této části je věnována velká pozornost poměrovým ukazatelům a jejich výpočtům. Teoretická část je zakončena specifiky finanční analýzy pro komernčí pojišťovnu. Výstupem práce je pak ověření relevance dat a poměrových ukazatelů finanční analýzy pro specifické odvětví pojišťoven z hledsika vývoje v čase a faktorů ovlivňujích jejich vývoj.

Multimodal Database Search
Krejčíř, Tomáš ; Stryka, Lukáš (referee) ; Chmelař, Petr (advisor)
The field that deals with storing and effective searching of multimedia documents is called Information retrieval. This paper describes solution of effective searching in collections of shots. Multimedia documents are presented as vectors in high-dimensional space, because in such collection of documents it is easier to define semantics as well as the mechanisms of searching. The work aims at problems of similarity searching based on metric space, which uses distance functions, such as Euclidean, Chebyshev or Mahalanobis, for comparing global features and cosine or binary rating for comparing local features. Experiments on the TRECVid dataset compare implemented distance functions. Best distance function for global features appears to be Mahalanobis and for local features cosine rating.

Activity of winning political parties on Facebook before the European Parliament elections in 2019
Bílá, Anja ; Hájek, Lukáš (advisor) ; Stauber, Jakub (referee)
This bachelor thesis focuses on communication on the social network Facebook in the Czech Republic in the election period of the European Parliament elections in 2019. The aim of the thesis is to analyze and interpret the data from the election campaigns of individual political parties, which obtained the mandate. The theoretical part of the thesis describes selected theories of political communication on social networks. It also presents the demographic structure of users who use social networks in the Czech Republic. He is also engaged in political marketing on the social network Facebook. The practical part analyzes the activity of political parties on the social network Facebook, which was part of the election campaigns. The winning political parties are relevant to this work. This data is selected and analyzed using ZoomSphere software. These are the frequency of published contributions by political actors, the time sequence of messages and their structure. Furthermore, the popularity of individual political entities and the response of potential voters of a particular political party on the social network are evaluated.

Berlin Plus - Relevant or Obsolete Mechanism of EU-NATO relations?
Hložková, Veronika ; Kučera, Tomáš (advisor) ; Karlas, Jan (referee)
This bachelor thesis deals with the verification of the relevance of the Berlin Plus Agreements, which became the official mechanism for the implementation of European Union- led operations using NATO's planning capabilities in 2003. To determine the relevance, I set out three aspects. The first assesses this mechanism by its use in practice in the form of military missions. The following perspective examines it from the perspective of involvement in planning and its occurrence in the key documents of both organizations. The last one looks for his presence in the professional discourse. I use assumptions based on historical institutionalism to determine the causes of the present state of relevance of these agreements. These include, in particular, an emphasis on historical and contextual assessment of the empirical survey, path- dependency, and unintended consequences. With this research set up, I have come to the conclusion that the Berlin Plus Agreement is partially relevant from today's perspective. I came up with the result after the Berlin Plus mechanism was not assessed positively by a single criterion. At the same time, however, it has proved that its existence has helped to maintain communication and a certain level of cooperation between the two organizations at times when there was no...

Participace veřejnosti na procesu EIA záměrů větrných elektráren
Mudra, Petr
Public participation in the EIA process of projects of wind power plants. Brno 2016. Diploma thesis. Mendel University in Brno, Faculty of Regional Development and International studies. The thesis deals with the participation of the public in the EIA process in the context of the construction of wind power plants in selected regions of the Czech republic. The first part of the work focuses on the comparison of individual regions from the point of view of the construction of wind power plants and installed capacity of wind energy. Most of the constructed wind power plants and at the same time, the largest installed capacity is in the Usti region. This region also has got the second greatest potential in the use of wind energy after the Vysocina region, so far is the installed capacity using 23 % of the total potential power in the region. The second part of the thesis describes the participation of the public in the EIA process, evaluates the public involvement in this process and at the same time, compares the region between them. The highest public participation in the EIA process is in the Olomouc region and South-Moravian region, where it is also about less than half approved of the project of wind power, compared to the other evaluated regions. In all examined regions is public opinion on the EIA process mainly reflecting the concern of the negative impact of projects of wind power stations on fauna and flora. The conclusion of the thesis is devoted to consideration of the comments received from the public related to the EIA proces for the projects of wind power plants.

Field tests relevancy (equipollence) of endurance predisposition of professional footballers
Paroulek, Martin ; Bunc, Václav (advisor) ; Česák, Petr (referee)
Title: Field tests relevancy (equipollence) of endurance predisposition of professional footballers. Made by: Bc. Martin Paroulek Supervisor: Prof. Ing. Václav Bunc, Csc. Aims: Contribute to solve problems with defining the level of endurance predisposition of professional footballers. Methods: 10 professional footballers were tested. Their average age was 19,1±0,9 years, average weight was 69,2±2,5 kg and average height was 178±4,2 cm. Data was obtained from three functional load tests. Data was processed by means of correlative analysis. Assumed level of equipollence among load tests was defined 0,7. Results: We haven't found significant relation betweeen measured figures of VO2max laboratory load test and measured figures of field 2 km run test. We even haven't found significant relation between measured figures of VO2max laboratory load test and measured figures of field endurance 20 m shuttle run test. As we can see from the results, field tests cannot be considered as adequate compensation of laboratory tests. More research is needed at this field of survey to be able to confirm it or adjust it. We are aware of limits of our survey and its value of notice, for example number of probands etc. It was confirmed that 2 km run test has higher level of equipollence (0,41) in laboratory load test...
