Maximizing the Diversity of Exposure in a Social Network [article]

Cigdem Aslay, Antonis Matakos, Esther Galbrun, Aristides Gionis
2018 arXiv   pre-print
In this paper, we take a step in this direction and propose a novel approach to maximize the diversity of exposure in a social network.  ...  This setting allows us to capture the balance between maximizing the spread of information and ensuring the exposure of users to diverse viewpoints.  ...  This work has been supported by three Academy of Finland projects (286211, 313927, and 317085), and the EC H2020 RIA project "SoBigData" (654024)."  ...

2020 Knowledge and Information Systems  
We formulate the problem of maximizing the diversity of exposure as a quadratic-knapsack problem.  ...  We do so by aiming to maximize the diversity of the information exposed to connected social-media users.  ...  The images or other third party material in this article are included in the article's Creative Commons licence, unless indicated otherwise in a credit line to the material.  ...

Co-exposure Maximization in Online Social Networks

Sijing Tu, Çigdem Aslay, Aristides Gionis
2020 Neural Information Processing Systems  
We experimentally demonstrate the quality of our proposal on real-world social networks.  ...  We show that the problem of maximizing co-exposure is NP-hard and its objective function is neither submodular nor supermodular.  ...  Acknowledgments Part of this work was done while the authors were with Aalto University, in Finland.  ...

The strength-of-weak-ties perspective on creativity: A comprehensive examination and extension

Markus Baer
2010 Journal of Applied Psychology  
In addition, I examined whether the joint effects of network size, strength, and diversity on creativity were further qualified by the openness to experience personality dimension.  ...  I hypothesized that idea networks of optimal size and weak strength were more likely to boost creativity when they afforded actors access to a wide range of different social circles.  ...  provide actors with exposure to different social worlds (e.g., colleagues in different parts of the organization, customers, competitors, suppliers) and considered this type of diversity as a moderator  ...

And yet, it is the position of users, and their exposure to diverse information that is often neglected in the current dialogue.  ...  Social implications -The societal implications of search engines, social networks and app stores for media diversity cannot be overestimated.  ...  Network effects play a role in the platform types: a consumer prefers to use the social network where many other consumers are.  ...

Cumulative Effect in Information Diffusion: Empirical Study on a Microblogging Network

Peng Bao, Hua-Wei Shen, Wei Chen, Xue-Qi Cheng, Yamir Moreno
2013 PLoS ONE  
However, few large-scale empirical studies are conducted to validate the existence of cumulative effect in the information diffusion on social networks.  ...  Cumulative effect in social contagions underlies many studies on the spread of innovation, behaviors, and influence.  ...  Bao et al. predicted the popularity of messages on social networks by leveraging the structural diversity of diffusion network [29] .  ...

The Social Life of Wireless Urban Spaces: Internet Use, Social Networks, and the Public Realm

Keith N. Hampton, Oren Livio, Lauren Sessions Goulet
2010 Journal of Communication  
In recent years, changes to the structure of people's social networks, the mass media, and the form of public spaces may represent a confluence of social trends that constrain exposure to diverse issues  ...  However, the level of social diversity to which wi-fi users are exposed is less than that of most users of these spaces.  ...  ACKNOWLEDGMENTS We extend our deepest appreciation to Fred Kent, Kathy Madden, Steve Davies and the Project for Public Spaces, and to William H. Whyte, who inspired this work.  ...
