Città, memoria e social network: partecipazione e condivisione su un gruppo Facebook
2018
il contributo propone una riflessione su alcune dinamiche dello spazio nei processi di virtualizzazione e sulle modalità di costruzione di una memoria condivisa della città attraverso lo studio di un gruppo sul social network Facebook. Gli autori analizzano alcune parti del gruppo “Palermo di una volta” dedicato alla storia della città siciliana e, con l’ausilio di diverse interviste effettuate ad alcuni membri del gruppo, mostrano il funzionamento di alcune dinamiche d’interazione dei gruppi tematici sui social network.
Viaggio nel mondo virtuale: commento pedagogico ai risultati della ricerca
2017
Quando si affronta da un punto di vista educativo il rapporto che sussiste tra social network, ragazzi e genitori, è importante basare la riflessione su un’analisi di dati empirici, che la orientino e la guidino verso una messa in atto di pratiche educative ben radicate nella realtà. Questo è ciò a cui tende la ricerca condotta dall’As.Pe.I., sezione di Brembate, con i ragazzi e i genitori del comune bergamasco. A partire dai dati raccolti, infatti, sono stati evidenziati temi, problemi e conseguenti prospettive da sviluppare e concretizzare in interventi educativi. In particolare, le proposte che verranno presentate si concentreranno su un approfondimento della relazione genitori-figli e s…
Siamo l'esercito del Selfie e non abbiamo più contatti
2017
Le tecnologie mobili influenzano profondamente il modo di pensare e di organizzare il sapere: tendenze, potenzialità e criticità. Le persone sviluppano un’adeguata concezione dei processi cognitivi implicati dagli strumenti multimediali e sono in grado di controllare tali processi in maniera funzionale. L'utilizzo di social media online, come Facebook, WhatsApp, Twitter, ecc., Sta diventando un fenomeno psicologico e sociale. Oltre il 55 per cento dei "Millennials" hanno preso un selfie e lo hanno condiviso sui social media e oltre 93 milioni di selfies vengono utilizzati ogni giorno con il rischio di condurre all'ossessione. Il Selfie è un'attività non così nuova ma popolare nella cultura …
Assisted labeling for spam account detection on twitter
2019
Online Social Networks (OSNs) have become increasingly popular both because of their ease of use and their availability through almost any smart device. Unfortunately, these characteristics make OSNs also target of users interested in performing malicious activities, such as spreading malware and performing phishing attacks. In this paper we address the problem of spam detection on Twitter providing a novel method to support the creation of large-scale annotated datasets. More specifically, URL inspection and tweet clustering are performed in order to detect some common behaviors of spammers and legitimate users. Finally, the manual annotation effort is further reduced by grouping similar u…
Knowledge Extraction from Biological and Social Graphs
2022
Many problems from real life deal with the generation of enormous, varied, dynamic, and interconnected datasets coming from different and heterogeneous sources. Analysing large volumes of data makes it possible to generate new knowledge useful for making more informed decisions, in business and beyond. From personalising customer communication to streamlining production processes, via flow and emergency management, Big Data Analytics has an impact on all processes. The potential uses of Big Data go much further: two of the largest sources of data are including individual traders’ purchasing history, the use of Biological Networks for disease prediction or the reduction and study of Biologic…

The role of social networking services in eParticipation
2009
Published version of a chapter published in Lecture Notes in Computer Science, 5694, 46-55. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-03781-8_5 A serious problem in eParticipation projects is citizen engagement – citizens do not necessarily become more willing to participate simply because net-services are provided for them. Most forms of eParticipation in democratic contexts are, however, dependent on citizen engagement, interaction and social networking because democratic systems favour the interests of larger groups of citizens – the more voices behind a political proposition, the greater its chances of success. In this context of challenges the study of s…
Factors affecting social integration and transversal skills of college students: a preliminary study
2015
International audience; This research, as a part of a PhD thesis in educational sciences relates to the social network and the transversal skills developed by the Bachelor's degree students ("Licence") in a French college. Overall, this work aims at identifying and estimating origins and effects of student social integration and transversal skills within the college careers. Four areas of student social integration and ten skills stemming from a reference table are measured by an original questionnaire. In this paper, the first preliminary results of this work are presented and reveal the influence of various personal and contextual factors on the integration and skills scores stated by stu…
Social network brand visibility (SNBV) : Conceptualization and empirical evidence
2018
Social media has become a new way of life that allows for real-time interaction among businesses (B2B) and consumers (P2P/C2C) as well as between business firms and consumers (B2C). Customers are increasingly accessing and using social networking sites (SNS), making it imperative for businesses and organizations to have a presence on these platforms to enhance visibility. The main purpose of this chapter is to provoke an agenda on the study of social network brand visibility (SNBV). We developed and proposed a definition of SNBV and report findings from a preliminary study. We further discuss implications for theory, research, and practice as well as the limitations and options for future r…
A privacy-aware framework for decentralized online social networks
2015
Online social networks based on a single service provider suffer several drawbacks, first of all the privacy issues arising from the delegation of user data to a single entity. Distributed online social networks (DOSN) have been recently proposed as an alternative solution allowing users to keep control of their private data. However, the lack of a centralized entity introduces new problems, like the need of defining proper privacy policies for data access and of guaranteeing the availability of user's data when the user disconnects from the social network. This paper introduces a privacy-aware support for DOSN enabling users to define a set of privacy policies which describe who is entitle…
