Nowadays email is commonly used by citizens to establish communication with their government. On the received emails, governments deal with some common queries and subjects which some handling officers have to manually answer. Automatic email classification of the incoming emails allows to increase the communication efficiency by decreasing the delay between the query and its response. This thesis takes part within the IMAIL project, which aims to provide an automatic answering solution to the Swedish Social Insurance Agency (SSIA) (“Försäkringskassan” in Swedish). The goal of this thesis is to analyze and compare the classification performance of different sets of features extracted from SSIA emails on different automatic classifiers. The features extracted from the emails will depend on the previous preprocessing that is carried out as well. Compound splitting, lemmatization, stop words removal, Part-of-Speech tagging and Ngrams are the processes used in the data set. Moreover, classifications will be performed using Support Vector Machines, k- Nearest Neighbors and Naive Bayes. For the analysis and comparison of different results, precision, recall and F-measure are used. From the results obtained in this thesis, SVM provides the best classification with a F-measure value of 0.787. However, Naive Bayes provides a better classification for most of the email categories than SVM. Thus, it can not be concluded whether SVM classify better than Naive Bayes or not. Furthermore, a comparison to Dalianis et al. (2011) is made. The results obtained in this approach outperformed the results obtained before. SVM provided a F-measure value of 0.858 when using PoS-tagging on original emails. This result improves by almost 3% the 0.83 obtained in Dalianis et al. (2011). In this case, SVM was clearly better than Naive Bayes.

Phishing är en metod som används av angripare på nätet för att lura sitt offer att dela med sig av känslig information som bankuppgifter, lösenord eller användaruppgifter. Författarnas syfte med denna studie är att undersöka ifall det är skillnad på utsattheten för phishing beroende på utbildningsbakgrund. Om de med utbildningsbakgrund inom IT eventuellt presterar bättre än de utan den bakgrunden eller om det går att hitta andra samband varför vissa lättare faller offer för phishing. I takt med att system blir allt säkrare blir den mänskliga faktorn den svaga länken. För är det något som är säkert är det att människor begår misstag och gör fel. Det handlar därför om att minimera dessa risker och ständigt vara i framkant för att bemöta cyberkriminaliteten. Det är viktigt att hitta svaren varför någon faller för phishing och hur det går att stärka människors förmåga att identifiera en phishing attack innan det är försent eftersom det annars kan få negativa konsekvenser. Resultaten togs fram genom en enkät där förmågan att identifiera phishing e-mails undersöktes. Det gjordes med hjälp av ett test där respondenterna fick en verklighetstrogen bild av olika phishing metoder i form av e-mails där det skulle identifiera om e-mailen var phishing eller autentiskt. Undersökningens resultat visar att de med utbildningsbakgrund inom IT hade lättare att dissekera vilka som var phishing och vilka som var autentiska. Denna undersökning replikerade även tidigare studiers resultat att kvinnor som grupp är något mer mottagliga för phishing.

The main purpose of this master's thesis is to create electronic mail room of The BUT. First of all I described problems concerning a digital signature, its use and safety, and as well as sphere of qualified certificates and method of their issuing by certification authority. The next part of the thesis deals with systems enabling electronic submission (so-called "Electronic Mail Room"). I have focused on available applications providing electronic submission service to civil offices, and subsequently analyzed functions that individual applications offer to the Mail Room clients as well as to authority staff. On the basis of gained knowledge and according CVIS requirements I created project of electronic submission for needs of the Brno University of Technology. Result of this thesis is the application of electronic mail room, implemented in BUT portal.

This master's thesis is a grounded theory study of the development of the Internet as a tool for political action in Japan by groups and individuals producing web pages on the issue of history textbook reform. Through the analysis of 14 in-depth interviews, a framework is developed for understanding the role the Internet has taken in political action in Japan. As activists utilize the Internet in political activism, the Internet appears to be developing into an anchor for continuing political activism. For activists, the Internet is a central point of reference for both mass communication and interpersonal communication activities. The model indicates that the political alignment of an activist is an important factor in determining his or her preference for either interpersonal or mass communication on the Internet. Activists on the left tend to use the Internet as a tool for interpersonal communication and coordination, while activists on the right tend to view the Internet as a tool for mass persuasion. The model of Internet activism developed in the thesis is also compared with models of communication derived from theories of technological determinism and social shaping of technologies. Consistent with technological determinist ideas, the Japanese case demonstrates that as activists rely on the Internet, other media show signs of becoming content for the new medium. However, the Japanese case also shows that pre-existing needs and the political framework of an activist have a strong shaping effect on Internet use, indicating the importance of a social shaping of technologies approach.

This thesis aims to understand Wolf-Rehfeldt’s place in the unofficial art world of the GDR by examining her work in light of her status as a clerical worker with social rather than professional ties to the art world. She stands out within the East German Mail Art context, not just for her inventive use of a typewriter to create abstract figurations, but for the way she used it to interject considerations of gender and power into a network of artists overwhelmingly dominated by men with her open-ended Typewritings.” Through historical research and close readings of her work, this study uncovers how Wolf-Rehfeldt's Typewritings indicate that Mail Art was a space to share stylistic experiments, and her sophisticated treatment of feminist and abstract themes. My research reveals that the record of who was involved in the GDR’s experimental art scene is incomplete, with still more to be found. A deeper look at Wolf-Rehfeldt’s background confirmed that she was more enmeshed in Mail Art than the historical record indicates, suggesting the need for further study on the influence and involvement of women in the movement.
