Online news, microblogs and other media documents all contain valuable insight regarding events and responses to events. Underlying these documents is the concept of framing, a process in which communicators act (consciously or unconsciously) to construct a point of view that encourages facts to be interpreted by others in a particular manner. As media discourse evolves, how topics and documents are...
This paper presents a perspective on Modeling an Adaptive Hypermedia Instructional System, having sound footings on research findings in context of high quality technology enabled learning environment. We propose a framework that is primarily based on the concept of reusable learning objects, media worthiness of components and instructional ergonomics. The goal of the framework is to cater protocols...
Social media has become an important factor in crisis response. From an improved situational awareness to facilitating communications, it supports responders in more effective crisis handling. Social media also enables affected communities to express their needs and others to respond directly. At the same time social media also poses challenges for responders, handling communications or data overload...
Crowdfunding platforms as a new way of financing in the web 2.0 have increased over the last years, but only little is known how users (project initiators and (potential) project backers) behave during a campaign. Using a dataset of 492 projects (including 10'439 donations) published on one of the dominant crowdfunding platforms in Switzerland, we explore the user behavior in crowdfunding. Our results...
As the use of computer-mediated communications has increased, the potential risk of online deception has grown -- as has the importance of better understanding human behavior online to mitigate these risks. Previous research has demonstrated that linguistic features provide crucial cues to detect deception, and that reasonable accuracy in detection of deception can be achieved by applying certain...
New digital technology has opened a broad range of ways in which individuals can engage with social movement organizations (SMOs). Although extant research has highlighted the role of digital action repertoires in political movements, the effects on SMOs' processes and structures still need to be elucidated. This study takes a deeper look into the organizational implications of broadening the set...
This study takes a network analysis perspective to understand communities of dissidents and allegiants formed on Facebook in relation to Sri Lanka's ethnic conflict. Networks representing dissidents and allegiants were formed based on levels of liking and commenting and analyzed across ethnic groups. The results show that the dissident network is more diverse in terms of ethnic composition and has...
Many organizations and individuals in the social sector face challenges in their capacity to deliver social services due to a lack of resources and formal recognition. In this environment, there is limited opportunity to sustain social development. To support this practical need, we espouse the application of information systems to support social development initiatives. In particular, we examine...
Innovation competitions are considered to be an instrument by which companies can inspire customers and employees to generate value-added ideas. However, there is little research on how the quality contributions are made and by whom. In this paper, a case study-based analysis is carried out at a global telecommunications company. Through the analysis of log files, the participating users are categorized...
Deep learning has emerged as a powerful technique to uncover deep structured, nonlinear features for various information processing tasks, such as image processing, speech recognition, and information retrieval. In this paper, we introduce a framework of utilizing a Deep Structured Semantic Model (DSSM) to build similarity features to enhance search engine relevance. To illustrate the effectiveness...
As research on government social media continues to grow in quantity and scope, this area calls for mapping and systematization, in order to stimulate better-informed studies in the future. This paper draws on a comprehensive review of government social media literature in the e-government and Information Systems (IS) fields to identify research foci and gaps. We propose a research-grounded model...
People are connected to their colleagues, customers, family and friends almost all the time and everywhere via virtual communication channels. However, constant social connectivity is a two-edged sword bringing about positive as well as negative effects especially in the professional context. Knowledge workers suffer from pervasive interruptions, escalating engagement, ineffectiveness, but also social...
In recent years, Web 2.0 applications have found their way into organizational practice with increasing demand for corporate social software to support in-ternal (e.g. networking, knowledge transfer) and ex-ternal (e.g. user-interaction, collaboration) processes. Already organizational changes are starting to be-come visible, so our goal is to conduct an exploratory study in order to shed light on...
Social media have become an established feature of the dynamic information space that emerges during crisis events. Both emergency responders and the public use these platforms to search for, disseminate, challenge, and make sense of information during crises. In these situations rumors also proliferate, but just how fast such information can spread is an open question. We address this gap, modeling...
Virtual teams play an important role in the modern economy, and many organizations struggle to overcome the weaknesses inherent in technology-mediated work. Drawing from a strong empirical foundation for identity-related outcomes in non-mediated settings, we propose that perceived virtual identity communication accuracy positively impacts virtual team trust and performance. We further propose that...
Communication technologies and approaches, such as mobile applications and social media enable individuals to share information with others ubiquitously. These voluntarily created data contain geographic information as well as user generated content such as images or text. Researchers and practitioners can gain highly valuable information by analysing and combining those different types of data. Earlier...
This paper considers empirical data gathered on the use of social media and online bystander reports in operative emergency response work. Interviews with 12 emergency response professionals have been conducted in order to understand the role of social media, as we need to look at how professional actors use and make sense of this technology as part of their work. Focus is on the use, interpretation,...
Most information systems (IS) research focuses on the effect of gamification or the impact of emotions on IS adoption. Moreover, no study differentiates between digital natives and digital immigrants, although theoretically there should be differences in their IS adoption. Digital natives are those from the generation that has grown up with digital technology, their characteristics and behavior are...
