Using Topic Modeling Methods for Short-Text Data: A Comparative Analysis
2020
With the growth of online social network platforms and applications, large amounts of textual user-generated content are created daily in the form of comments, reviews, and short-text messages. As a result, users often find it challenging to discover useful information or more on the topic being discussed from such content. Machine learning and natural language processing algorithms are used to analyze the massive amount of textual social media data available online, including topic modeling techniques that have gained popularity in recent years. This paper investigates the topic modeling subject and its common application areas, methods, and tools. Also, we examine and compare five frequen…

Discovering Homophily in Online Social Networks
2018
During the last ten years, Online Social Networks (OSNs) have increased their popularity by becoming part of the real life of users. Despite their tremendous widespread, OSNs have introduced several privacy issues as a consequence of the nature of the information involved in these services. Indeed, the huge amount of private information produced by users of current OSNs expose the users to a number of risks. The analysis of the users’ similarity in OSNs is attracting the attention of researchers because of its implications on privacy and social marketing. In particular, the homophily between users could be used to reveal important characteristics that users would like to keep hidden, hence …
Un luogo dell’immagine. Flickr e la visione collettiva on-line.

Con questo apporto si intende effettuare un'analisi generale dei principali aspetti teorico-culturali aperti dalle nuove tecnologie di condivisione delle immagini. In particolare ci si concentra sulle modificazioni antropologiche che discendono da tale innovazione.
Las redes sociales y la innovación educativa. La experiencia del Geoforo. Balance anual de 2012
2012
El aumento de la participación en los foros ha facilitado el intercambio de opiniones y argumentos sobre la innovación educativa. Podemos definir este momento como la creación de una red social con intereses profesionales coincidentes: la mejora del aprendizaje de los hechos sociales, en especial los que tienen una característica geográfica. Los datos que se aportan en este balance anual nos indican que se está asentando el Geoforo allí donde hay grupos locales, lo que nos confirma que este blog es una red de redes.

La eclosión de la opinión del alumnado sobre la enseñanza de la Geografía. El geoforo iberoamericano en 2015
2015
Los datos que se aportan en esta síntesis anual nos indican que existe un crecimiento muy relevante no sólo en las visitas sino, sobre todo, en la participación del Geoforo Iberoamericano a través de las opiniones de alumnos y docentes. La didáctica de la Geografía se transforma en educación ciudadana por medio de las redes sociales, una aspiración que se ha gestado desde el año 2009. La colaboración de las personas de un lado y otro del Océano Atlántico nos permitirá definir con más rigor y precisión los desafíos de la formación docente en los próximos años.
Predicting the availability of users' devices in Decentralized Online Social Networks
2018
The understanding of the user temporal behavior is a crucial aspect for all those systems that rely on user resources for daily operations, such as decentralized online social networks (DOSNs). Indeed, DOSNs exploit the devices of their users to take on and share the tasks needed to provide services such as storing the published data. In the last years, the increasing popularity of DOSN services has changed the way of how people interact with each other by enabling users to connect to these services at any time by using their personal devices (such as notebooks or smartphones). As a result, the availability of data in these systems is strongly affected (or reflected) by the temporal behavio…
Beyond good and evil: The impact of digital environment in family life
2019
Internet has changed the way we interact with others and has become an essential tool for daily activities. Children and adolescents are the main users of new digital technologies and their first contact with a screen happens increasingly earlier in life. Its premature use can be dangerous: technology represents a “supernormal stimulus” that can act on the brain reward circuit and affect neural development. In this article we describe the effects of technology on the brain, well-being, social and family relationships, highlighting both positive and negative ones: rather than defining a priori any type of technology as “good” or “bad”, we should consider how specific applications are used in…
Political Identities Constructed on a Social Network: The Labour Party on Facebook Boards
2019
This paper is concerned with how an (institutional) political identity is constructed on a Social Network (SN) wall, which represents the political identity of the party as designed in digital interactive contexts, and where political image constructions are eventually accepted or negotiated by the digital audience. Like other political parties, the Labour Party resorts to online platforms for official accounts and political message dissemination (Gerbaudo 2014; Boyd 2014) and constructs its (online) identity. Since interaction is seen (Baumann 2000; De Fina 2011) as the most important locus for the production of identities, this study looks at Facebook boards as interactional sites where t…
