In recent years, we have witnessed an increasing consolidation of different realms where citizens can deliberate and discuss a variety of topics of general interest, including politics. The comments on news posts in online media are a good example. The first theoretical contributions called attention to the potential of those spaces to build a <em>healthy </em>(civic and participatory) public sphere, going much deeper in the process of political dialogue and deliberation (Fung, Gilman, & Shkabatur, 2013; Lilleker & Jackson, 2008; O’Reilly, 2005; Stromer-Galley & Wichowski, 2011). Polarization has been configured as a constant feature of the quality of the mentioned dialogues, particularly in Mediterranean countries (polarized pluralists’ cases). One of the research challenges at the moment has to do with the scrutiny of polarization within the political deliberation provoked by news stories. The goal of this article is the analysis of political dialogue from the perspective of the polarization in the increasingly popular network YouTube, which is presenting very particular characteristics. Using a sample of almost 400,000 posted comments about diverse topics (climate change, the Catalonian crisis, and Political parties’ electoral ads) we propose an automated method in order to measure polarization. Our hypothesis is that the number of comments (quantitative variable) is positively related to their polarization (qualitative variable). We will also include in the examination information about the ideological editorial line of newspapers, the type of topic under discussion, the amount of traceable dialogue, etc. We propose an index to (1) measure the polarization of each comment and use it to show how this value has behaved over time; and (2) verify the hypothesis using the average polarization of comments for each video.
Social media has significantly transformed how political discussions and deliberations occur, mainly by providing a digital realm for the public sphere. This study aims to analyse the extent of polarised opinions across Spain, Italy and the United Kingdom regarding COVID-19 during 2020 within social media. To do this, we examined YouTube comments (n=111,808) using automatic analysis and machine-learning techniques based on algorithms. This methodological strategy denoted an innovative and unique quantitative approach for this field of study. In line with previous research, the hypothesis was that the degree of polarization does not crystallize in the same manner in different countries’ digital spheres. Therefore, it could be said that higher levels of polarization occur amongst Southern European countries like Spain and Italy (both countries adhering to a polarised pluralism model), compared to other countries ascribing to the liberal model (the United Kingdom in our study), which provides evidence supporting previous research studies. The results confirmed the hypothesis that the polarization of digital deliberation between Spain and Italy is higher than in the United Kingdom. But, also, the findings based on more disaggregated analysis suggest that the most polarized attitudes are even rewarded by other users in Mediterranean countries. Las redes sociales han transformado de forma muy significativa la forma en la que se produce el diálogo político, impulsando una configuración digital de la esfera pública. El presente artículo tiene como objetivo el análisis de la deliberación producida en las redes sociales, con un especial énfasis en la polarización. Tomando como referencia los comentarios observados en YouTube sobre la COVID-19 durante 2020 en España, Italia y Reino Unido, lo cual arroja una muestra de 111.808 comentarios, se aplicaron una serie de técnicas automáticas de análisis basadas en algoritmos, lo que supone una metodología cuantitativa novedosa en este ámbito de estudio. En línea con lo señalado por trabajos previos, la hipótesis que se plantea en este artículo es que el grado de polarización no se da con la misma intensidad en las esferas digitales de distintos casos. De esta manera, cabe esperar unos mayores registros de polarización en la esfera digital de los países del sur de Europa, adscritos a un modelo de pluralismo polarizado, que en países de otros modelos como el liberal. Los resultados confirman la hipótesis, verificando que no solo se observa mayor polarización en España e Italia que en Reino Unido, sino que, a nivel desagregado, los hallazgos apuntan a que la actividad más polarizante obtiene mayor aprobación en los países mediterráneos de nuestra muestra.
Conflictos armados y la construcción de narrativas a través de Twitter. El caso de la guerra entre Armenia y Azerbaiyán Armed conflicts and the construction of narratives on Twitter.
The objective of this chapter is to explore the Arab region’s media systems in order to assess the sources of information available to civil society. The chapter is divided into four parts, which provide: first, an account of the political and regulatory environment in which the media have to operate; second, a description of traditional media; third, an overview of satellite television, which is paramount in the region; and fourth, an analysis of internet access in the region. The data analysed in this chapter clearly illustrates that one of the results of the Arab Spring has been the attempt to further control information flows. With the exception of a few countries, especially Tunisia and Algeria, almost all the governments in the region have adopted rules in the hope of controlling information in a more effective way. Of course, this does not mean that citizens are unable to obtain political information through other channels than those accepted by governments. Satellite TV is a first fracture in the closed ecosystem, but events in recent years suggest that it is not entirely free from attempts at regularisation and control. Nonetheless, there are other tools to serve the public that can be treated as sources of information and, therefore, as media: namely the Internet and all its facets.
Las leyes de educación comportan, para todos los partidos políticos, una de las correas transmisoras de su proyecto ideológico. De este modo, cada uno de los diferentes gobiernos españoles, como ocurre en otros países, han llevado a cabo modificaciones legislativas con el fin de implementar políticas de un signo más cercano a sus intereses partidistas. A su vez, el contexto mediático, siguiendo los postulados de los académicos en comunicación política, ha tendido a apoyar u oponerse a dichas reformas, generando una escena polarizada. La presente investigación realiza un análisis del panorama español, durante los últimos cuarenta años, sobre los impactos que las reformas educativas han suscitado en el ámbito mediático. Se emplean para ello nuevas metodologías de aprendizaje de máquina (machine learning), complementadas con el desarrollo de una serie de medidores diseñados para captar fenómenos sociales complejos dentro de escenarios de variabilidad semántica. Los resultados han evidenciado una clara relación entre partidos políticos y medios, así como el posicionamiento que estos últimos, en consonancia con su línea editorial, mostraron con respecto a las reformas educativas que se iban sucediendo a lo largo del periodo de estudio.
