    This paper, seeks to examine the correlation between stock price and public sentiment expressed through social media. Through twitter scraping and pre- processing, sentiment can be extracted from text. The paper will be based on a heuristic approach to natural language processing. Furthermore, the paper will rely on the most common forms of sentiment analysis, using a rule-based and a machine-learning approach as a starting point and weigh these up against each other. Finally, we will continue with the best performing method, and weigh this up against real market data in a pursuit to find a correlation, should one exist. The paper found a sentiment-to-market accuracy 75%. And the accuracy score utilizing the rules-based approach of 72,72%.

    This paper examines how Russian President Vladimir Putin incorporates the use of history in his speeches and articles with regards to how he positions Russia in its relation to Ukraine. The analysis is structured around three central places of remembrance (danish: erindringssteder): The Kyivan Rus which focuses on the close historical relation between Ukraine and Russia; the heritage of the Sovietunion in relation to how the union defined the borders of Soviet-Ukraine; World War II, ukrainian nationalism and its relation to nazism which centers around how Putin relates nazism to the current ukrainian political elite. The analysis concludes that Putin primarily utilizes the three places of remembrance to legitimize Russia's current invasion of Ukraine. Putin finds the distribution of territories during the soviet era to have been theft, and a complete violation of Russia's integrity. Furthermore, he seeks to protect ethnic russians within the borders of Ukraine from a genocide, instigated by ukrainian nationalists and neo-nazis, who continue the tradition of atrocities commited during World War II. Finally, Putin perceives Ukrainians and Russians as a single people, basing his claim on common history, language, and culture. Thus he implies that ukrainians should unite under Russia, as Russia is the more legitimate state.

    This project will deep into the motives and reasons behind cultural destruction. It will underline the will to entirely wipe off a distinctive group of population and its culture. Taking Syria as our main case given the events of the last decade; centring in the civil war where lives and art have been lost forever, together with the morale of its population, which fled to other countries in big numbers throughout the war. As for the perpetrators, ISIS will be the focus of our project, guilty of intentionally destroying many monuments, especially in Syria. Before explaining and answering to the questions of the project regarding culture, it is more than mandatory to analyse Syria’s history, tribes and regions. After reaching the core of our project and describing the possible reasons behind these actions, the third part of our project, which focuses on the emotional sphere of the victims. War brings with itself grief, loss, damage and destruction to a country and its material environment. To focus on the emotional attachment and emotional damage during this war shall be a matter of discussion nevertheless. We will not only analyse and discuss cultural destruction and the loss for humanity whenever perpetrators decide to damage forever something so important as our, as humans, common and singular past.

    This paper revolves around the development of an LSTM multiclass classifier, constructed using Keras as framework and CRISP-DM as project process, with the purpose of classifying natural language into varying degrees of toxicity. The model takes a starting point in an existing toxic comment classification challenge from Kaggle.com, and makes a first iteration, engineered towards the requirements in the challenge. In this first iteration, several measures are taken to avoid common pitfalls of neural networks. The model is then held up against principles of freedom of speech including The Harm Principle and The Offence Principle by John Stuart Mill and Joel Feinberg respectively. After evaluating upon the models performance in the light of these principles, a second iteration is constructed with some design changes. For reasons i.a. related to the dataset, this operation is less successful. The paper concludes that it is possible to make a good multiclassification tool for shallow NLP problem, but gets less efficient in later iterations as we try to apply it to more concrete purposes.

    This project was set out to explore the role of the Turing Test in the development of Artificial Intelligence (AI), with emphasis on the historical perspective. This report contains an introductory presentation of the Turing Test and Artificial Intelligence. Furthermore, it presents two methods for analysis. The first method is a quantitative search in extracting the number of results from Google Scholars for search range between 1950 and 2019. The searched terms are ‘Turing Test’ and ‘Artificial Intelligence’. The second method is the one used for the analysis of two case studies, ELIZA and Google Duplex. In exploring the historical development, ELIZA is an early research topic from 1966 and Google Duplex is a contemporary project from 2018. This report concludes that the Turing Test appears to have played a role in the historical development of AI. Results from the quantitative search show that there is an exponential growth, followed by a short stabilisation, before it begins to decay towards the last decade. Both case studies failed when subjected to a strict Turing Test. Though when subjected to the Total Turing Test, Google Duplex seems to surpass it. Finally, this report also concludes that the Turing Test may no longer be relevant, as mediums for AI have evolved beyond text-based and most developments are no longer concerned with tricking humans.

    The main goal of the project will be to investigate to which extent ‘authentic’ culture isperformed. The main theories used, in order to obtain an understanding of culture andperception, will be Bourdieu’s Habitus, Butler’s Performativity and Goffman’s ImpressionManagement. The analysis will be structured around three different aspects: the object, thephenomenology and the discursive, connected by Brinkmann’s ontological triangle from TheEpistemology of Working with Everyday Life Materials. The theories will be applied in order toanalyze interactions made in Venice, by the group members, in order to determine to whichextent they had performed their culture, and how this can affect the ‘authenticity’ in culture.

    The field of subtitling is certainly one of the underrated and underexplored areas in the academic world. This project intends to outline the lengthy evolution of subtitles as it was being shaped throughout the last century by experimenting with its different forms and uses. The historical perspective sheds light on the field of subtitling and looks at its functions, technology, and usages, tracing its change from the origin to its present-day form. The intention of covering the historical side of the field is to familiarize the reader with the profession and its practices before stepping into a more detailed observation, covering linguistic and semiotic elements of subtitling. As a medium of communication, it is a field that can reach countless viewers. It can be used as a tool for educating the illiterate, deaf and the hard of hearing, students of second language, enriching vocabulary, maintaining language skills for the elderly, not to mention its capability of translating information to a non-native-speaker audience for the purpose of exchanging cultural wealth.

    The subject of this research project is to perform a comparative analysis of a section of the Danish media coverage in three different newspapers of the Israel/Palestine conflict, aiming to highlight an evolution or change, in the discourses used in these papers. The comparative analysis is based upon empirical material of eighteen newspaper editorials, discussing three chosen historical events, during the Israel/Palestine conflict. The historical events which the articles will represent, are the six-day war, the first intifada, and the second intifada. The reasoning behind the selection of these historical events is a necessity, for a broad perspective of the conflict, to make discursive changes more apparent. Additionally the chosen events are all substantial and well documented, and it is through these events that the change of discourse will be presented. To answer the research question thoroughly, a combination of the two distinctive theories relating the study of discourse will be used. The theories are Norman Fairclough’s ‘Critical discourse analysis’ and the ‘Discourse theory’ of Ernesto Laclau and Chantal Mouffe. Both offer an extensive look into the dynamic and complex structures of discourses, and will together provide a set of nuanced methods to complete the analysis. The overall scientific field in which these theories exist, is within the area of social constructivism which also relates to the theory of power by Michael Foucault. The analysis of the various discursive structures of the historical period in question, will focus on describing the more specific types of discourse of the different media outlets, separately and in unison, by shifting incorporations of the theories that have been presented. The precise method for this analytical procedure will be to locate and underline how certain phrases and specific usages of language are in a dynamic relationship with what they aim to represent, and how discourses in general seem to undergo striking, even insidious transformations through their use. Finally, the analysis of this paper attempts to answer the more difficult question, relating the causes behind these discursive transformations, and attributes them to the acknowledgement of discourses in general, as fundamentally transformative properties, where the use of language by its conception, is inevitably changing and dynamic in nature.

    The motivation for this project was based on the newly founded movement DiEM25 (Democracy in Europe Movement 2025) and their manifesto. The movement’s ideas and visions are based on the critique of the European Union’s handling of the economic, refugee and migration crisis’, that has been debated throughout Europe in recent years. With their manifesto, DiEM25 has formulated an idealistic alternative vision for the future Europe. This assignment seeks to find answers to what kind of alternative this is. More specifically; which kind of cosmopolitanism is expressed in the manifesto, and which European concept historical traditions this cosmopolitanism builds upon. The analysis conducted in this project will be a comparative concept historian analysis of the cosmopolitan vision formulated in the DiEM25 Manifesto. The assignment concludes that the manifesto entails a potential utopian cosmopolitan vision of re-democratising Europe, and more specifically the EU in our present modern and globalised world. Furthermore, it concludes that the the cosmopolitanism in the DiEM25 Manifesto builds on a long tradition of cosmopolitan ideas, leading back to Immanuel Kant initial ideas of cosmopolitanism, through post world war and the thoughts of Ulrich Beck up until the 21st century and the notion of New Cosmopolitanism.
