Elsevier Online Social Networks and Media Journal (OSNEM)

Special issue on
Information and Opinion Diffusion in Online Social Networks and Media

Submission Deadline: August 31st, 2021
Information diffusion in Online Social Networks and Media  (OSNEM) has a major role, among many others, for recommendation systems, advertising, and political campaigns. Moverover, the way information circulates in OSNEM impacts on the formation of opinions and on the social roles of users and their influence on others. The OSNEM role in information and opinion diffusion has dramatically increased since the emergence of the COVID-19 pandemic, with many physical activities being "migrated" to the online world.

OSNEM are extensively used for spreading information, opinions and ideas, but also to propagate fake news and rumors and these threats to trust in information are posing even more serious socio-economic challenges during the pandemic. Therefore, prevention of spam, bots and fake accounts, information leakage,  trustworthiness of information and  trust between users are relevant research issues associated with information diffusion. Investigating ways through which information and opinion spread can be controlled (e.g., by modifying the underlying network structure) is also fundamental. 

This special issue seeks contributions pushing the state of the art in all facets of information and opinion diffusion in Online Social Networks and Media. We solicit manuscripts where quantitative and/or data-driven approach is used to investigate information and opinion diffusion in OSNEM.

Topics include, but are not limited to:
- Dynamics of trends, information and opinion diffusion in OSNEM
- Recommendations and advertising in OSNEM
- Spread of news, topics, and opinions
- Trust, reputation, privacy in OSNEM information and opinion diffusion
- Rumors and fake news spreading in OSNEM
- Information and disinformation diffusion in OSNEM at the time of COVID-19
- Opinion formation, diffusion and polarization related to COVID-19
- Bots and fake users detection
- Influence analysis and social influence
- Identification of diffusion sources and influencers
- Methods to modify/control/maximise information and opinion diffusion

Online Social Networks and Media is a multidisciplinary journal for the wide community of computer and network scientists working on developing OSNEM platforms and services and using OSNEM as a big data source to mine, learn and model the (online) human behaviour.
