The popularization of Online Social Networks has changed the dynamics of content creation and consumption. In this setting, society has witnessed an amplification in phenomena such as misinformation and hate speech. This dissertation studies these issues through the lens of users. In three case studies in social networks, we: (i) provide insight on how the perception of what is misinformation is altered by political opinion; (ii) propose a methodology to study hate speech on a user-level, showing that the network structure of users can improve the detection of the phenomenon; (iii) characterize user radicalization in far-right channels on YouTube through time, showing a growing migration towards the consumption of extreme content in the platform.

The Impact

Understanding information propagation in online social networks is important in many practical applications and is of great interest to many researchers. The challenge with the existing propagation models lies in the requirement of complete network structure, topic-dependent model parameters and topic isolated spread assumption, etc. In this paper, we study the characteristics of multi-topic information propagation based on the data collected from Sina Weibo, one of the most popular microblogging services in China. We find that the daily total amount of user resources is finite and users’ attention transfers from one topic to another. This shows evidence on the competitions between multiple dynamical topics. According to these empirical observations, we develop a competition-based multi-topic information propagation model without social network structure. This model is built based on general mechanisms of resource competitions, i.e. attracting and distracting users’ attention, and considers the interactions of multiple topics. Simulation results show that the model can effectively produce topics with temporal popularity similar to the real data. The impact of model parameters is also analysed. It is found that topic arrival rate reflects the strength of competitions, and topic fitness is significant in modelling the small scale topic propagation.

Analysis And Synthesis

The chapter is conceptual, based on analysis and synthesis of social network theory and e-consumer literature. Despite a broad spectrum of disciplines that investigate social networks and the interest of marketing practitioners in the consequences of social networks, there are still areas open for research into networked-consumer behavior in marketing. Based on previous theoretical and empirical research, this study examines and discusses the influence of social network structure and ties in matched dyads, recommendation diffusion, social contagion and co-consumption influence, and individual motivations to spread market information. The chapter proposes a theory of matched dyadic ties in close networks of connections as a proxy for information about the potential market that is difficult and expensive for businesses to measure or access directly.

ResumenLos espacios de la Web 2.0 se han configurado en el panorama digital como una herramienta al servicio de las estrategias empresariales de los anunciantes. Las capacidades de escucha de los clientes (actuales y potenciales) y de creación comunidades en torno a la marca, entre otras, facilitan a la compañía la puesta en marcha de una orientación empresarial hacia el cliente a través de estas herramientas. Los objetivos del presente artículo han sido analizar el empleo que las empresas están haciendo de los espacios de la Web 2.0, en este sentido, y estudiar la aplicación que se está haciendo de los programas de Customer Relationship Management a espacios como las redes sociales online. La metodología se ha centrado en tres técnicas de investigación cualitativas, a saber: la investigación documental, el estudio de 50 case studies y la realización de una encuesta auto-administrada con preguntas abiertas a profesionales del sector de la comunicación publicitaria online. Los resultados destacan la idoneidad de espacios como las redes sociales online, los blogs y las plataformas de video, por este orden, para llevar a cabo una estrategia de orientación empresarial hacia el cliente. Los espacios de la Web 2.0 ofrecen a las empresas la posibilidad de personalizar su mensaje y mantener una comunicación bidireccional con el cliente en aras de conseguir su fidelización.Abstract:Web 2.0 spaces have become a tool at the service of advertisers business strategies in the current digital scenery.
