    In epistemic community, people are said to be selected on their knowledge contribution to the project (articles, codes, etc.) However, the socialization process is an important factor for inclusion, sustainability as a contributor, and promotion. Finally, what does matter to be promoted? being a good contributor? being a good animator? knowing the boss? We explore this question looking at the process of election for administrator in the English Wikipedia community. We modeled the candidates according to their revisions and/or social attributes. These attributes are used to construct a predictive model of promotion success, based on the candidates's past behavior, computed thanks to a random forest algorithm. Our model combining knowledge contribution variables and social networking variables successfully explain 78% of the results which is better than the former models. It also helps to refine the criterion for election. If the number of knowledge contributions is the most important element, social interactions come close second to explain the election. But being connected with the future peers (the admins) can make the difference between success and failure, making this epistemic community a very social community too

    Vote Prediction Models for Signed Social Networks

    Voting is an integral part of the decision-making mechanism in many communities. Voting decides which bills become laws in parliament or users become administrators on Wikipedia. Understanding a voter's behaviour and being able to predict how they will vote can help in selecting better and more successful policies or candidates. As votes tend to be for or against a particular agenda, they can be intuitively represented by positive or negative links respectively in a signed network. These signed networks allow us to view voting through the lens of graph theory and network analysis. Predicting a vote translates into predicting the sign of a link in the network. The task of sign prediction in signed networks is well studied and many approaches utilize social theories of balance and status in a network. However, most conventional methods are generic and disregard the iterative nature of voting in communities. Therefore this thesis proposes two new approaches for solving the task of vote prediction in signed networks. The first is a graph combination method that gathers features from multiple auxiliary graphs as well as encoding balance and status theories using triads. Then, it becomes a supervised machine learning problem which can be solved using any general linear model. Second, we propose a novel iterative method to learn relationships between users to predict votes. We quantify a network's adherence to status theory using the concept of agony and hierarchy in directed networks. Analogously, we use the spectral decomposition of the network to measure its balance. These measures are then used to predict the votes that comply the most with the social theories. We implement our approaches to predict votes in the elections of administrators in Wikipedia. Our experiments and results on the Wiki-RfA dataset show that the iterative models perform much better than the graph combination model. We analyse the impact of the voting order on the performance of these models. Furthermore, we find that balance theory represents votes in Wikipedia elections better than status theory

    Revisiting Request for Adminship (RfA) within Wikipedia: How Do User Contributions Instill Community Trust?

    Research into successful Request for Adminship (RfA) within Wikipedia is primarily focused on the impact of the relationship between adminship candidates and voters on RfA success. Very few studies, however, have investigated how candidates’ contributions may predict their success in the RfA process. In this study, we examine the impact of content and social contributions as well as total contributions made by adminship candidates on the community\u27s overall decision as to whether to promote the candidate to administrator. We also assess the influence of clarity of contribution on RfA success. To do so, we collected data on 754 RfA cases and used logistic regression to test four hypotheses. Our results highlight the important role that user contribution behaviors and activity history have on the user’s success in the RfA process. The results also suggest that tenure and number of RfA attempts play a role in the RfA process. Our findings have implications for theory and practice

    Despite the importance of promoting socially responsible citizenship in Internet age with the global massive spread of IT consumption, there is a paucity of research for scrutinizing the impact of ICT tools such as Social Networking Sites on citizens of the Middle East and North Africa region and/or investigating their tendency toward digital transformation. In the information age, Internet and its applications are creating a ‘network state’ due to the continuous interaction of SNS by people on their daily personal and professional lives; which made it a rich data bank for researchers to analyze and predict people’s behavioral, cultural and societal change. This research focused on the digital impact of SNS on various aspects of life in the society of Egypt and the forecast of its subsequent normal progression over time. The research questions were; what are the factors affecting the usage of SNS and its impact on the society of Egypt? In addition to, How SNS usage and IT developments are likely to affect future changes in Egypt’s culture and societal behaviors in the arena of human computer interaction and information communication technology? Hence, the research investigated those questions on recent years where there is still not enough complete specialized analysis nor mature socio-technological researches have been developed about the online society of Egypt. In specific, it concerned with studying the interaction of human practices with information network applications and the latter role in changing human cultures and societal behaviors from personal, governmental and business perspectives. This study is an example of interdisciplinary research, linking cultural theories and social networking phenomena with human-mediated informational technology and communication studies contributing to the emerging field of Internet studies. Therefore, this research’s best matching philosophy is interpretivism, the research approach is inductive and the utilized research strategy was grounded theory and surveys through four employed quantitative and qualitative research methods over two phases. Phase one implemented observational study, survey questionnaire and focus group sessions; while interviews were accomplished in phase two. Outcomes are reached through applying descriptive statistics of structural equation modeling via using SPSS 20.0, AMOS 20.0.0, Tableau 10.4, and MS 2010 Excel; in addition to, qualitative content analysis using NVivo 11. Findings of interweaved data collection methods supported in investigating the research questions and testing the hypotheses of the research proposed SDR model. Consequently, these research findings deduced that the Egyptian online society is affected by SNS forming a pre-digitalization stage. In addition to the research’s major offering of the SDR model, there were four others emerged contributions to knowledge base. One of the main challenges of research in this domain is the dynamic pace of both technological developments and users’ preferences. Hence, this research study impacts the growing knowledge repository with five contributions about the significant role of SNS in transforming people’s daily activities which can shed lights of more novel questions for other neighboring countries as well as regarding other ICT tools for future studies

La investigación llevada a cabo en esta tesis ofrece un marco para los modelos abiertos de apoyo a la decisión, y sugiere que el uso de fuentes internas y externas de conocimiento pueden ser utilizadas más allá de la innovación del producto o servicio para la toma de decisiones con el soporte de tecnologías emergentes. Las contribuciones teóricas de esta tesis sostienen que las organizaciones ya no pueden confiar en la tecnología de apoyo a las decisiones que únicamente se centran en la reducción de la frontera entre los aspectos racionales y no racionales de la conducta social humana, sino por el contrario, deben considerar la red dinámica de la organización para el apoyo a la decisión. Por otra parte, las implicaciones prácticas de esta tesis alienta a las organizaciones a pensar estratégicamente acerca de cómo las tecnologías emergentes pueden ayudar a la toma de decisiones y también cómo los modelos de decisión resultantes pueden ser utilizados para navegar por el entorno complejo existente y, a su vez, forjar vínculos más fuertes con los clientes, proveedores y más amplios de la red de la organización.This thesis presents a framework for open models of decision support through a compendium of papers that links research on the inward and outward flows of knowledge to the organization and decision support technologies. The framework presents underlying factors driving new and more open models of decision support. A typology of decision support models is offered considering types of problems organizations and managers charged with decision-making face. Thesis essay #1 suggests a perspective of the changing landscape for decision support technology and the advancement of new technology for open models of decision support. This study provides insight from an evolutionary perspective of expertise that has shaped the field of decision support technologies. The investigation sets out to reveal the changing landscape of expertise in supporting decision-making using technology and sheds light on the new role that experts will play in organizational decision-making. It suggests that a significant change in how decision-making is being supported which challenge the traditional role of experts and non-experts. Finally, this paper explores opportunities for decision support technology integration and the added benefits artificial intelligence can bring to collective intelligence tools. Thesis essay #2 investigates the ‘aggregate’ typology within the open model decision support framework. A forecasting problem is used to highlight the complexity of demand forecasting in supply-chain management within the film industry and how technology is leveraged for effective supply-chain management decisions. The investigation compares two decision support technologies: expert systems and collective intelligence tools and illustrates how the film industry uses each in forecasting box-office revenue. Finally, this essay explores the combined benefits in integrating each support technology for more accurate forecasting. Thesis essay #3 is a longitudinal study over a 10 year period that uses IBM Innovation Jams as a context for large-scale collaboration within the ‘platform’ typology. This essay investigates the role of innovation jams on organizational change as IBM learned to engage with a new model of organizing innovation. It describes the role innovation jams have played in shaping the practice of open innovation at IBM. This essay uses the musical genre of a “jamband” as a metaphor to describe the emergent development and use of innovation jams as a way to understand organizational change. This longitudinal study brings innovation jam research up-to-date and presents innovation jams as they evolved from a concept, a management tool, and service. The essay concludes with a discussion on the implications of the findings for theorizing about new models of organizing innovation for organizational change. Research conducted in this thesis offers a framework of open models of decision support that suggests that the use of internal and external sources of knowledge can be leveraged beyond product or service innovation, to include decision-making supported by emerging technology. Theoretical contributions of this thesis argues that organizations can no longer rely on decision support technology that solely focus on bridging the boundary between rational and non-rational aspects of human social behavior but instead, must consider the larger dynamic organizational network for decision support. Moreover, practical implications of this thesis encourages organizations to think strategically about how emerging technology can support decision making and the resulting decision support models to navigate the complex environment they work in and in turn, to forge stronger links with customers, suppliers, and the wider organizational network

    Semantic discovery and reuse of business process patterns

    Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

    Social movements as networks of communication episodes

    Social movements (SMs) are common, yet complex phenomenon of study, generating eclectic and even conflicting perspectives on what actually constitutes a SM. This notion points towards the need of an inclusive framework that attempts to talk with rather than past conflicting perspectives. The purpose of this dissertation is to develop a hybrid theoretical framework that incorporates three SM perspectives: (1) SMs as aggregates, (2) SMs as networks, and (3) SMs as symbolic interactions. I argue that a framework of SMs as networks communication episodes (CAMs) is one way to build a successful hybrid approach, arguing that SMs consist of relationships between and within actors and events. In order to put the CAM framework to use, I used multidimensional exponential random graph modeling (MERGM) to analyze four different SMS: (1) 1970s US Energy Policy Domain, (2) 1970s US Health Policy Domain, (3) 1980s Anti-Stalinist mobilization in Poland, and (4) 1980s US Labor Policy Domain. Multidimensional network simulation was used to determine which organizing patterns correlate to instrumental and expressive theories of collective action and MERGM was used to uncover the dominant multidimensional organizing patterns in the empirical data behind each SM. Results revealed that most collective action events were organized by single organizations across all four SMs and that the Polish SM was the only movement out of the four that contain positive estimates of parameters conducive to network theories of collective action. Based on these results, a working model of factors that are theorized to influence the CAM structure is proposed, along with an application to the Anti-Stalinist mobilization in Poland and anti-Three Mile Island nuclear power plant mobilization. Moreover, based on different patterns in the CAM framework, a typology of different modes of organizing for collective action is developed, challenging a recent and common perspective of collective action as either organized or un-organized
