La difusión de los nuevos medios que el web 2.0 pone a disposición representa una posibilidad muy importante para los políticos que quieran modificar las reglas de la comunicación con los ciudadanos y trasmitir una propia imagen que no sea mediada por la televisión, los periódicos y otros medios de comunicación tradicionales. A través de un análisis de los perfiles de Twitter de algunos políticos italianos, podemos observar como ellos intenten difundir una "autopresentación" más espontánea y directa, aunque al origen de esta presentación haya una clara estrategia que mira a una propaganda personal. ; The new instruments made available by the web 2.0 represent an important opportunity for politicians who aim to change communication rules with citizens and to transmit a self-image not mediated by television, newspapers and other traditional mass media. Through an analysis of the Twitter profiles of a number of Italian politicians, we can observe their attempt to disseminate a more direct and spontaneous "presentation of self", although behind it there is a clear strategy pursuing a personal propaganda.

With the proliferation of social media, textual emotion analysis is becoming increasingly important. Sentiment Analysis and Emotion Detection can be useful to track several applications. They can be used, for instance, in Customer Relationship Management to track sentiments towards companies and their services, or in Government Intelligence, to collect people's emotions and points of views about government decisions. It is clear that tracking reputation and opinions without appropriate text mining tools is simple infeasible. Most of these tools are based on sentiment and emotion lexicons, in which lemmas are associated with the sentiment and/or emotions they evoke. However, almost all languages but English lack high-coverage inventories of this sort. This thesis presents several sentiment analysis tasks to illustrate challenges and opportunities in this research area. We review different state-of-the-art methods for sentiment analysis and emotion detection and describe how we modeled a framework to build emotive resources, that can be effectively exploited for text affective computing. One of the main outcome of the work presented in this thesis is ItEM, which is a high-coverage Italian EMotive lexicon created by exploiting distributional methods.It has been built with a three stage process including the collection of a set of highly emotive words, their distributional expansion and the validation of the system. Since corpus-based methods reflect the type of the corpus from which they are build, in order to create a reliable lexicon we collected a new Italian corpus, namely FB-NEWS15. This collection has been created by crawling the Facebook pages of the most important Italian newspapers, which typically include a small number of posts written by the journalists and a very high number of comments inspired by long discussions among readers about such news. Finally, we describe some experiments on the sentiment polarity classification of tweets. We started from a system based on supervised learning that was originally developed for the Evalita 2014 SENTIment POLarity Classification task (Basile et al., 2014) and subsequently explored the possibility to enrich this system by exploiting lexical emotive features derived from social media texts.

This corpus-assisted analysis looks at the work of James R. Martin and Peter R.R. White for what concerns the appraisal theory which is the centre of this investigation. The aim of this study is to provide an answer of how news language is impacted by political discourse in the particular scenery of Brexit, that is by the various instruments journalists may adopt to create a piece of news and thus influence the reader. More specifically, to discover if attitudinal language is utilised in news language and which approaches are preferred by journalists. Moreover, the study provides a glossary to better understand Brexit.

This essay proposes an investigation on the forms of contemporary cynicism, combining the interpretation of political drama with reflections of the daily life sociology, particularly referring to Simmel, Goffman and De Certeau. In an expanded historical perspective from the 21st century metropolis to the communication media of the 20th century, it proposes a reconstruction of the political action and of certain moment of its imagination. A moment that shall be studied as from its relations with money, time acceleration and sensory overstimulation, which institute a new image of social relations. Cynicism seems to be, in the conditions created by metropolis and media, the cultural form more suitable for management and organization of daily events in public sphere. ; Esse ensaio propõe uma investigação sobre as formas do cinismo contemporâneo, conjugando a interpretação do drama político com reflexões da sociologia da vida cotidiana, com particular referência a Simmel, Goffman e De Certeau. Numa perspectiva histórica ampliada da metropóle do século XXI aos meios de comunicação do século XX, propõe uma reconstrução da ação política e de determinado momento de seu imaginário. Um momento que será estudado a partir de suas relação com o dinheiro, com a aceleração do tempo e com a superestimulação sensocial, que instituem uma nova imagem das relações sociais. O cinismo parece ser, nas condições criadas pela metrópole e pela mídia, a forma cultural mais adequada para a gestão e organização dos eventos diários na esfera política.

Our project aims to create, implement and deploy a platform based on a decision support system for gathering eyewitness reports to improve the situation-awareness in the aftermath of an emergency, focusing in particular on earthquakes. While doing so, we would like to find out if an approach combining opportunistic and participatory sensing methods is possible. Our system, in fact, focuses on detecting eyewitnesses with an opportunistic approach and then aims to transform these potential eyewitnesses into volunteers willing to share information. The platform retrieves earthquake notifications from an official channel and, immediately after, exploits the messages shared on Twitter for a fixed time-slot. In doing so, we collect messages posted by potential eyewitnesses. Data mining and natural language processing techniques are performed in order to select meaningful and comprehensive sets of tweets. We then concentrate on the filtered tweets in order to try to engage with their authors and enhance situation awareness. Information retrieved by our system can be extremely useful to all the government agencies interested in mitigating the impact of earthquakes, as well as news agencies looking for new information to publish.

Freedom of speech ought to be interpreted as a value linked with different aims of a democratic society. It is not admissible to accept a freedom of speech which conceals harmful intentions against a single person or a social community. The historical defense of freedom of speech is based on the enlargement the debated of ideas, rather than on a subjective exercise of personal extravagance. To respect religious feelings and another personal aspects in an absolute limitation of freedom of speech. Because of that, we do not agree with identification of Muslim religion with terrorism that has been published, through Mahoma's caricatures, in some European newspapers.

In a sociological perspective, this article is focus on the analysis of measuring immigrants integration through Italian statistical administrative system. Afterward focusing shortly on methodological and theoretical approach following in the essay (the sociology of public statistic), in the second paragraph it is analyzed the Italian public statistic system, the fundamental frame in order to develop an analytic framework to study the social and institutional process of measuring immigrants integration (the third paragraph). On this basis, the latest paragraphs show the finding of our analysis: after a promising beginning at the end of XX Century by the input of the Law "Turco-Napolitano", the question has been put aside for a long time. Just in recent years, it has caught by European Union inputs. This process is not only a methodological sequence but the finding of a gradual political and national systemic overlook about the importance of integration in Italian Society.
