Normalized social distance
Šlerka, Josef ; Souček, Jiří (advisor) ; Petříček, Miroslav (referee) ; Macek, Jakub (referee)
This dissertation thesis deals with the application of the concept of information distance to the social network data analysis. We consider this data as recorded acts of social action. As such, they express certain attitudes, values and intentions. We introduce a formula for calculating the Normalized Social Distance and, based on the series of case studies, we prove the usefulness and validity of this approach. The application of formal mathematical and computer science techniques to massive data records of human action in social network environments is enabled by the change brought by new media and the associated technological advancement. This change is accompanied by a gradual transition of research methods in the humanities, referred to as the onset of digital humanities. This approach is characterized by the application of quantitative methods in the field of humanities and the discovery of new data areas useful for analyses. In case of social media data, the differentiation between quantitative and qualitative methods is no longer valid. A good example is also this thesis, in which information theory specifically combines the methods of a traditional social network analysis and the Goffman's frame analysis of human action. Keywords Information distance, Normalized Social Distance, Kolmogorov...

The right to be forgotten on the internet
Jůzová, Jana ; Papík, Richard (advisor) ; Šlerka, Josef (referee)
Diploma thesis The Right to be Forgotten on the Internet applies to the functions of Internet search engines, search algorithms and the impact of the digital footprint that on the Internet user essentially leaves. With this issue is, on the one hand, inseparably linked the protection of personal data in the online environment, on the other hand the constitutionally enshrined right to information and other fundamental rights. Not ignored should be also the risk of censorship of the Internet. An application of the right to be forgotten adds a whole new dimension to this problems. The right to be forgotten is inferred from the judgment of the European Court of Justice on 13 May 2014 in the case Costeja versus Google Spain, where an Internet user named Mario Costeja Gonzáles first succeeded with a request of removal of unflattering information about himself from results of the search engine Google. Thus a reform precedent will have a big impact on seeking information on the Internet in the future, since the pronouncement of the judgment about the removal of his personal data may ask any European Internet user. The thesis aims to analyze the issue of right to be forgotten in the context of searching for information on the Internet in the European Internet environment - it means not to be searched on the...

DSLR Video and its Impact on the Conventions in Filmmaking
Nuska, Petr ; Získal, Bohuš (advisor) ; Šlerka, Josef (referee)
The thesis deals with the involvement of digital single-lens reflex cameras (DSLR) with video-capturing capacity in documentary and ethnographic film, more particularly, it examines whether and to what extent these genres were influenced by a trend called DSLR revolution. The main contribution of the work is a qualitative analysis of the testimonies of ten filmmakers, who used DSLR cameras while working on their films during the years 2010-2014. The synthesis of this analysis is conceptualised as a reconstruction of the process of decision-making whether to use or not to use a DSLR camera, considering its benefits (affordability, technical and aesthetic qualities, compactness and simplicity) and its limits (ergonomics, visual artifacts, workflow limits). The reconstruction of this decision-making process is considered in the context of specific experiences of the participants and it focuses on the impact of DSLRs on filming workflow and final product. The final chapter deals with the DSLR revolution as a social trend which was stimulated by the influence of online communities of DSLR filmmakers who actively participated in the course of the revolution. Appendix of the thesis contains a brief description of the film projects of all participants and the model of the structured questionnaire used for data...

Glitch in new media art: Technological error as a subject of aesthetic interest
Šašek, Filip ; Souček, Martin (advisor) ; Šlerka, Josef (referee)
This thesis introduces the use of technological failure in visual arts, described as glitch art in the Anglo-American literature, and reveals its specific qualities. The author examines creative exploration of glitch both in image compression formats, and in the user interface of web sites, computer games or operating systems. In addition, the research presents arguments that advocate glitch art in a broader artistic discourse. It does so firstly by analogy, when it compares glitch art manifestations to conceptual and visual qualities of the paradigmatic works of art and artistic movements, and secondly by Dickie's institutional classification, when it analyzes glitch art communities and appreciation by the curatorial, critical and academic public. The central argument of this thesis is that glitch art next to a purely aesthetic experience provides an insight into the heart of technology, which exposes its functionality. Thus it contributes to a deeper understanding of its physical, structural and ideological fundamentals, that have become in everyday life almost invisible due to the logic of immediacy. Given the highly relative nature of the term glitch the thesis does not seek a hard definition of its specifics, but rather asks the cause of this naming (designation) that is why we perceive a...

Ways of using Tor anonymous network
Schamberger, Pavel ; Šisler, Vít (advisor) ; Šlerka, Josef (referee)
This diploma thesis deals with ways of using Tor anonymization network both from the point of view of the use in the positive sense and the use in the negative sense, the abuse. The aim of this work is to identify different ways of using the network and to quantify network abuse based on analyzed abuse reports. First, the basic concepts are defined and the development of the Internet and identification technologies in its environment are briefly described. Then, the concept of Onion routing, based on which the Tor network works, together with more technical details about the functioning of the network, is introduced. Last but not least, the Tor Browser is described as the most common tool for using the Tor network along with the types of users who use it. The last chapter of the theoretical part introduces the problem of network abuse. The practical part is primarily solved in the form of a quantitative analysis of abuse, due to their volume of almost 3 million. Quantitative analysis is done using the statistical language R and basic mining data, text mining and statistical methods. The analyzed data are related to several large nodes of the Tor network and contains several years of history. Although the total number of complaints increases almost exponentially over time, complaints about malicious...

Semiotic interpretation of Kant's aesthetics
Šlerka, Josef ; Petříček, Miroslav (advisor) ; Ševčík, Miloš (referee)
The Semiotic lnterpretation of Kanťs Aesthetics deals with the relations between Peirce's serniotic concepts and some aspects of Kant' s philosophy and aesthetics. The first part, named Peirce And His Philosophy, presents basic terms and concepts of Peirce's philosophy. The second part, named Kanťs aesthetics, identifies some mutual elements of Peirce's and Kanťs approach. Therefore it interprets some basic concepts of Kanťs philosophy and aesthetics as semiotic, namely it tries to define the concept of beauty and sublimity by means of Peirce's distinction of icon and index. In the following analysis the text focuses on the aspect of subjectivation and sensuality in the experience of beauty and sublimity. Finally, the third part, named The Leve/s of Thought, shows that this interpretation belongs to a wider context of human thought levels based on the axes of the irrational/rational and absurdity/active skepticism.
