Social Media Data in an Augmented Reality System for Situation Awareness Support in Emergency Control Rooms
2021
AbstractDuring crisis situations, emergency operators require fast information access to achieve situation awareness and make the best possible decisions. Augmented reality could be used to visualize the wealth of user-generated content available on social media and enable context-adaptive functions for emergency operators. Although emergency operators agree that social media analytics will be important for their future work, it poses a challenge to filter and visualize large amounts of social media data. We conducted a goal-directed task analysis to identify the situation awareness requirements of emergency operators. By collecting tweets during two storms in Germany we evaluated the usefu…

Studying micro-communities in Facebook Communities
2018
In the visionary view of the future Internet, named the Next Generation Internet, a current idea is to have a user-centric approach where human behavior models will be used to define the networks or to manage services. During the last years, a great trend in current Social Media platforms is to offer the opportunity to establish and join groups of people online. Despite human behaviour in current Online Social Media have been studied in depth, characteristics of these aggregations of people in content-based communities are still unknown. In this paper, we propose an evaluation of micro-communities of users inside the big network of Facebook groups to understand how and when users are active…
Warm experts for elderly users : who are they and what do they do?
2018
This paper examines “warm experts”—that is, nonprofessional persons who help inexperienced users come to terms with digital devices—and their significance for the use of digital media in everyday life by elderly Swedes. We analyze data from a national survey (N = 1264) and from qualitative, semistructured interviews with 18 elderly Swedes (aged 65+). Our data reveal that the warm expert usually is a closelyrelated person, often a child or grandchild, who is strongly involved in nearly every stage of technology domestication, from appropriation (i.e., identifying the need, buying the item, and installing and adjusting it) to incorporation (i.e., choosing and downloading suitable apps, teachi…
Trading Data for Health
2021
mHealth apps are growing in popularity among smartphone users. Such apps often contain social features that enable users to compare their behavior with others but to function, mHealth apps require users to share health information which is considered a threat to individuals’ privacy. Building on social comparison theory and research on privacy decision-making, we investigate the effects of users’ social comparison orientation and privacy attitudes as well as the potential mediating effect of health information disclosure on users’ intention to use a dietary app. Relying on a PLS-based structural-equation model in a sample of N = 528 participants, our study supports claims of a positive effe…
Cyber-Identities and Social Life in Cyberspace
2011
Information and communication technology gradually transform virtual communities to active meeting places for sharing information and for supporting human actions, feelings and needs. In this chapter the authors examine the conceptual definition of virtual community as found in the traditional cyberliterature and extend it to accommodate latest cybertrends. Similar to the ways that previous social and mass media dissolved social boundaries related to time and space, cyber-communities and social software seem to also dissolve the boundaries of identity. This, in turn, questions the trust, privacy and confidentiality of interaction. The authors present a way of classifying and viewing self-pr…
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…

The interplay between media-for-monitoring and media-for-searching: How news media trigger searches and edits in Wikipedia
2016
This study investigates how traditional news media and Internet services have become entangled in recipients’ habits of gathering information on current topics. Push media enable citizens to scan the issue environment while pull media enable them to seek out in-depth information if information needs have been elicited. Furthermore, content quality in many pull media may increase when more users generate content, removing flaws and adding information. We expected that TV and newspaper coverage of an issue will lead to increases in (a) searches for and (b) user edits in related articles in the online encyclopedia Wikipedia. Our findings reliably support the hypotheses, but the extent to whic…
