Limits of social media monitoring in humaniterian crises
Böhm, Jan ; Šlerka, Josef (advisor) ; Sedláček, Jakub (referee)
Limits of social media monitoring in humanitarian crises This paper explores the use of social network data in humanitarian crises. I introduce three theoretical pillars - the techno-optimist concept of digital humanitarians, which describes how social network data improves the ability of humanitarian organizations to locate people in need of assistance. The second theoretical pillar is an analysis of the use of Facebook and Twitter in the context of the so-called Arab Spring, where I show that each network has specificities that need to be taken into account. I then present the concept of techno- colonialism to show how much of a problem it can be when the use of technology is approached without critical reflection. The theoretical introduction is followed by literature review and my own research. The aim of the literature review is to determine whether the limitations and potential risks of using social network data are perceived by current research. The review shows four main directions that the research addresses - the processing of so- called big crisis data, the analysis of specific tools, the possibilities of crisis management using big data, and critical reflection on the limits of social media monitoring. The literature review concludes by stating that critical reflection on the topic is not...
Conversation design: principles of voicebot design for natural communication with people
Kološová, Štěpánka ; Šlerka, Josef (advisor) ; Sedláček, Jakub (referee)
The thesis Conversation Design: Principles of Voicebot Design for Natural Communication with People addresses the question of how robots can naturally interact with humans and aims to create a model of conversational design rules. This will be developed based on insights from the literature and will also be supported by data from real conversations between humans and voicebots. The methodology of this thesis is qualitative analysis. In the theoretical part of the thesis I discuss how communication between people works. I describe how conversation can be viewed and how conversation analysis approaches it. In the next part I describe how voice assistants work and focus on how they can talk to people. The second part of the thesis is a literature search. Here I explore the approaches and perspectives of authors who are experts in conversation design, UX design, voice technology, linguistics, sociology, psychology and other fields. I summarize the authors' findings into nine competencies and skills that a virtual assistant should have. In the analytical section, I analyze three virtual assistant scenarios and the calls in which people interacted with them. I look at these scenarios from the perspective of those nine skills and analyze them using a set of questions. In the results of the analysis, I...
Personal data as a commodity: how does the data market work, what is data worth and what Czech internet users know about it
Cieslar, Marek ; Šisler, Vít (advisor) ; Šlerka, Josef (referee)
Personal data extraction is an inherent part of today's internet. The intention of this work is to outline the market with personal data; how it functions, which circumstances have formed it and how it is being perceived by the public. The theoretical part relies on existing academic knowledge, media articles and other relevant sources which focus on data market and aggregation. One of the theoretical part's objectives is to present existing principles on how the price of personal data can be determined by users and by the market. Findings from the theoretical part will be enriched by a qualitative research which, by the means of interviews, reveals to what extent are Prague university students aware of online data collection, how they value the data and what is their opinion on that matter. Despite the gravity that online data extraction imposes on society, the qualitative research described in this work is probably one of the first in Czechia that focuses on this topic and that can therefore serve as a starting point for future exploration. Key words: personal data, user data, data extraction imperative, online privacy, internet privacy, data value, data market, data brokers, data aggregators, targeted ads, personalized advertising
Instagram as a business tool
Kabir, Karim ; Šlerka, Josef (advisor) ; Sedláček, Jakub (referee)
Today, the social media have affected all aspects of human life. The most significant change in the behavior of users, after the emergence of the social media, is their way of communication and its extent. Today, Instagram, a social network, has a significant influence on the marketing activities of companies and it presents new ways of communicating with new, as well as established customers. The goal of this Thesis is to critically analyze the sales business activities in the environment of the Instagram social network. In the Thesis, we identify the basic target groups, areas of business used in this environment and types of goods that are sold the most often in them. The Thesis itself will be based on the initial mapping of the marketing and practices in the environment of social networks, especially in the environment of the Czech and Slovak Instagram.
Francophone Hip Hop Lyrics from the Perspective of Digital Humanities
Klimentová, Julie ; Šlerka, Josef (advisor) ; Sedláček, Jakub (referee)
This paper contains an explorative analysis of French rap lyrics. The focus of the work is to answer three questions: What is the vocabulary used in the French rap lyrics? What are the topics present in the French rap lyrics? Are media and technology a significant topic in French rap lyrics? The methods used to obtain the answers to the research questions can be listed as follows: literature research, data collection of French rap lyrics, statistical textual analysis, and algorithmic topic modelling. The findings confirm previous research on the subject by supporting claims that the level of non- standard language in French rap lyrics is not as high as myths suggested. In terms of the topics, the topic modelling confirms that there is a variety of themes present in French rap lyrics, including anti- systemic sentiments, struggle, censorship, and false information presented by the authorities.
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...
