This paper proposes a novel service-oriented mobile social networking platform called MS2A for disaster situations. MS2A consists of two layers: service layer and application layer. The service layer is implemented based on the service-oriented architecture (SOA) to ease application developments. By extending and composing the web services at this layer, application developers can efficiently and...
In this paper, we explore changes in both structural and semantic characteristics of a scientific social network. We trace the emergence of knowledge, what we refer to as ideation, through publication data from two conferences in a sub-field of Computer Science. Social network analysis is used to determine structural characteristics of the co-authorship networks, and we perform semantic network analysis...
Exploiting the social network paradigm in the context of online shopping opens a new world of opportunities to sellers and consumers, and constitutes a new theoretically interesting domain for scholars to investigate. The present paper discusses why to study and how to theorize about online social shopping networks (OSSNs), defined as digital arrangements via which individuals connect to each other...
Social media refer to technology artefacts that support various actors in a multiplicity of communication activities for producing user-generated content, developing and maintaining connections and social relationships, or enabling other computer-mediated interactions and collaborations. Despite the growing proliferation of social media articles, the topic of Organization Social Media (OSM) has hitherto...
Perhaps, one of the most recent IT-based solutions nowadays is social media solution. Many organizations have created their own Facebook and Twitter pages, and employ social media tools to monitor their standing in the social networks. However, not all of them have been successful in employing these social solutions. As a matter of fact, we attempted to investigate the most important factors in implementation...
Social Cloud Computing is an emerging online collaboration paradigm which is characteristic of many socially oriented electronic platforms. The operation of such a platform requires computational infrastructure to facilitate the platform itself as well as the services enabling its basic operation. While this infrastructure currently requires capital-intensive investments, we believe it is possible,...
This study aims to understand the mechanisms of disaster response network evolution by quantitatively examining the actors' attachment behaviors in a real disaster collaboration networks. We aim to do this by identifying the characteristic of existing actors and its impact in forming new connection over time. To quantify actors' attachment logics (i.e., preferential attachment), different options...
Due to future markets shifts as well as current market dynamics industries like the automotive industry OEMs have to be able to handle both exploration and exploitation simultaneously, a capability which is called 'organizational ambidexterity'. Using data from German and Austrian premium OEMs as well as leading-edge suppliers of the automotive industry present work sheds light on the questions what...
This work presents an exploratory study of the different types of technology-mediated relationships that are formed in a sociotechnical system. More people each day are connecting with each other through social networks, online communities, and other forms of virtual environments. This study offers a framework for understanding how technology, user interactions, and user relationships are connected...
Today, Big Data is drawing a lot of attention and popularity and is aspiring enterprises to utilise more efficiently their data to help them understand how to better function, grow and manage as a business. Enterprises are aware that to derive real business value from Big Data and seek competitive advantages, they need to have available the right tool to extract, capture and organize a wide variety...
Web 2.0 has provided for a rapid growth of computer mediated social networks. We first discuss how to enrich the domain of social network modeling by introducing ideas from fuzzy sets and related soft computing technologies. One is with the introduction of fuzzy graphs representing the networks. A second is the use of the fuzzy set based paradigm of computing with words to provide a bridge between...
Adoption processes in network effect markets -- like the ICT industry -- often lead to so-called "lock-ins" which means that one single standard or technology gets adopted by almost all market participants. Based on the work of Arthur [1] we present a simulation based model explaining a market's tendency to lock-in by means of two factors: the strength of network effects and the network...
Rapid proliferation of information technologies has generated sheer volume of information which makes scientific research related information searching more challenging. Personalized recommendation is the widely adopted technique to recommend relevant documents to researchers. Current methods are suffering from mismatch problem and match irrelevance problem and fail to generate highly related results...
Many of the 1.5 billion users of social media send or receive messages or post or access new content every day. The personal, social, political and business implications of this volume of activity are profound. Extracting useful information from this activity presents a challenge for scientists, technologists and also scholars in other disciplines. Taking the data deluge from on-line social media,...
