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 …
Consentimiento de los menores de edad en las redes sociales: especial referencia Tiktok
2022
RESUMEN. El uso masificado de las redes sociales trae consigo una ingente cantidad de consecuencias jurídicas tanto en el ámbito del derecho de los contratos, como en materia de protección de datos, así como en el ámbito del derecho de los consumidores.

Mobile Search - Social Network Search Using Mobile Devices
2008
During the last years progress in Web search engines has been made to the point that relevant information can be reached easily most of the time. However very little empirical research has been carried to study Web search in highly dynamic social network environments composed of mobile devices. The aim of this work was therefore to investigate novel approaches that took advantage of the social network environment inherent to mobile peer-to-peer paradigm. The work focused mainly on the development of a prototype for mobile search concept. The prototype was built on top of Drupal content site management system. This study suggests that the methods presented can be a complement to traditional …
Mapping the scientific research on wine and health (2001-2011)
2013
[EN] There have been a substantial number of studies suggesting possible health benefits from polyphenols in wine, especially red wine. These hypothetical effects, in addition to those of alcohol, are attributed by many to antioxidant and antiinflammatory effects of the polyphenols. The aim of this paper was to map the scientific research on wine and health by using bibliographic analyses of papers published during the period 2002−2011. Papers were published in 535 different journals and in 106 different subject categories, the most productive journals being the Journal of Agricultural and Food Chemistry, Food Chemistry and Molecular Nutrition, and Food Research, and the most productive sub…
Cross-Social Network Collaborative Recommendation
2015
Online social networks have become an essential part of our daily life, and an increasing number of users are using multiple online social networks simultaneously. We hypothesize that the integration of data from multiple social networks could boost the performance of recommender systems. In our study, we perform cross-social network collaborative recommendation and show that fusing multi-source data enables us to achieve higher recommendation performance as compared to various single-source baselines.
Tracing Potential School Shooters in the Digital Sphere
2010
There are over 300 known school shooting cases in the world and over ten known cases where the perpetrator(s) have been prohibited to perform the attack at the last moment or earlier. Interesting from our point of view is that in many cases the perpetrators have expressed their views in social media or on their web page well in advance, and often also left suicide messages in blogs and other forums before their attack, along the planned date and place. This has become more common towards the end of this decennium. In some cases this has made it possible to prevent the attack. In this paper we will look at the possibilities to find commonalities of the perpetrators, beyond the fact that they…
The Footprints of a “Mastodon”: How a Decentralized Architecture Influences Online Social Relationships
2019
Decentralized online social networks (DOSNs) have recently emerged as a viable solution to preserve the users' privacy and ensure higher users' control over the contents they publish. However, little is known about the backlashes that the decentralized organization and management of these platforms may have on the overlaid social network. This paper fills the gap. Specifically, we investigate how a decentralized architecture based on distributed servers impacts the structure of the users' neighborhood and their ego-networks. Our analysis relies on social data gathered from the decentralized micro-blogging platform Mastodon, the newest and fastest-growing decentralized alternative to Twitter…
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.
The social perspective of the main MOOC platforms through Facebook

Facebook, como red social, ofrece un medio potente de comunicación social a través de la Red, conectando usuarios con intereses comunes. En este estudio se analizan las cuentas de Facebook de 7 de las principales plataformas de MOOC: Coursera, EdX, Future Learn, Harvard Extension, Miríada X, Stanford Online y Udacity, con el fin de describir el modo en que estas emplean sus cuentas de Facebook como espacio digital de comunicación, información e interacción social con sus usuarios. Para ello, se han utilizado herramientas de medición online sobre el crecimiento y la visibilidad de las cuentas, el contenido publicado y la interactividad con los seguidores. Los resultados evidencian que el núm…
