User and group networks on YouTube: A comparative analysis
2015
International audience; YouTube is the largest video-sharing social network where users (aka channels) can create links to any other users. Moreover, initially, users were allowed to create and join special groups of interest. Therefore, two types of online social networks can be defined. First, a user network where the nodes represent the users and the edges represent the social ties (friendship) between users. Second, a group network where the nodes represent the groups and the edges represent the social ties between groups, due to shared users. As the group network can be apprehended as the ground-truth overlapping community graph (where the nodes are the discovered communities and the l…
User profile matching in social networks
2010
International audience; Inter-social networks operations and functionalities are required in several scenarios (data integration, data enrichment, information retrieval, etc.). To achieve this, matching user profiles is required. Current methods are so restrictive and do not consider all the related problems. Particularly, they assume that two profiles describe the same physical person only if the values of their Inverse Functional Property or IFP (e.g. the email address, homepage, etc.) are the same. However, the observed trend in social networks is not fully compatible with this assumption since users tend to create more than one social network account (for personal use, for work, etc.) w…
Detecting Inference Channels in Private Multimedia Data via Social Networks
2009
International audience; Indirect access to protected information has been one of the key challenges facing the international community for the last decade. Providing techniques to control direct access to sensitive information remain insufficient against inference channels established when legitimate data reveal classified facts hidden from unauthorized users. Several techniques have been proposed in the literature to meet indirect access prevention. However, those addressing the inference problem when involving multimedia objects (images, audio, video, etc.) remain few and hold several drawbacks. In essence, the complex structure of multimedia objects makes the fact of detecting indirect a…
Young generation and accessibility to health dissemination: TikTok as a case study.
2022
Social media interactions represent an accessible way for young people to get health information and provide a form of public discourse about health. It is against this backdrop that experts and other health professionals have turned to digital platforms (e.g., TikTok) to share educational content about timely or touchy topics, and to spread awareness, specifically among younger users. This paper aims to explore these digital platforms where professionals provide health information that is specifically tailored for a young audience and attempts to explore the discursive negotiation of healthcare and health accessibility in digital social settings. In light of a social media critical discour…
Semantically-enhanced advertisement recommender systems in social networks
2017
El objetivo principal de la investigación es estudiar y diseñar un entorno de recomendación publicitaria en las redes sociales que puede ser enriquecido mediante tecnologías semánticas. A pesar de que existen muchas aplicaciones y soluciones para los sistemas de recomendación, en este estudio se diseña un framework robusto con un rendimiento adecuado para poder ser implementado en las redes sociales con el objetivo de ampliar los propósitos de negocio. De este objetivo principal se pueden derivar los siguientes objetivos secundarios: 1. Superar las limitaciones iniciales de los métodos clásicos de recomendación. 2. Aumentar la calidad y precisión de las recomendaciones y el rendimiento del …
Aviokompāniju reklāmu raksturojums sociālo tīklu tīmekļa vietnēs Facebook un Twitter
2018
Reklāma ir profesionālā diskursa žanrs, kas tiek izmantots komunikācijai ar sabiedrību. Mūsdienās internets un sociālo tīklu tīmekļa vietnes tiek bieži izmantotas reklāmas nolūkos. Šī pētījuma mērķis bija analizēt lingvistiskās un paralingvistiskās iezīmes sociālo tīklu tīmekļa vietnēs Facebook un Twitter publicētajās aviokompāniju reklāmās. Pētījums tika balstīts uz Kuka (Cook, 1992) piedāvāto diskursa analīzes modeli, kas ietver teksta un konteksta analīzi. Pētījuma rezultāti parādīja, ka šo reklāmu tekstos izmantotā valoda ir vienkārša un lasītājam draudzīga, kas ir panākts, pārsvarā izmantojot vienkāršus teikumus, kā arī lietojot kontrakcijas un saīsinājumus. Tā arī imitē sarunu ar lasī…
Technostress and social networking services: Explaining users' concentration, sleep, identity, and social relation problems
2018
It is common for users of social networking sites and services (SNS) to suffer from technostress and the various associated strains that hinder their well‐being. Despite prior SNS stress studies having provided valuable knowledge regarding SNS stressors and their use consequences, they have not examined the various strains related to well‐being that those stressors can create nor the underlying SNS characteristics. To address this gap in the research, we used a qualitative approach involving narrative interviews. As a contribution, our findings reveal four types of strains related to well‐being (concentration problems, sleep problems, identity problems, and social relation problems) as well…
Redes, complejidad y Arqueología: otra forma de ver el pasado
2018
La ciencia moderna se ha benefi ciado de los intentos del positivismo y neopositivismo por explicar el mundo sensible, que han generando grandes avances en el mundo de la ciencia, pero que han tenido problemas a la hora de plantear una “Teoría del Todo”. Hay que destacar el hecho de que toda explicación de la realidad es siempre un modelo simplifi cado, que se basa en alguna teoría. Durante los años 90, con el fi n de avanzar en la comprensión de la realidad empírica, comenzaron su andadura lo que se conoce co mo Ciencias de la Complejidad. A través de ellas se pretende explicar una serie de fenómenos comúnes a todos los sistemas formados por elementos interrelacionados, que como un conjunt…
Il digitale nell'educazione: ambienti, dispositivi, apprendimenti
2014
Nel volume si affronta la problematica dell’apporto delle tecnologie per l’apprendimento nell’azione educativa e didattica. I diversi contributi si orientano verso una prospettiva di lavoro che configura le tecnologie come struttura significativa per accogliere i bisogni educativi delle nuove generazioni, in ambienti a loro congeniali che si sviluppano rinnovando precedenti sistemi di conoscenza e di comunicazione. L’essenza della ricerca riguarda il come si modificano i modi di apprendere nei soggetti, dal momento in cui i media digitali occupano uno spazio rilevante nelle loro esperienze. Occorre costruire una progettualità educativa capace di mediare efficacemente tra pratiche sociali e …
