Supporting industrial processes by monitoring and visualizing collaborations
No full textIn modern dynamic industrial engineering collaboration contexts, professionals such as the facilitators or meeting coordinators, are required to guide participants before, during and after a collaborative process in order to evaluate individual and group performances and the levels of idea generation, discussion, etc. This paper presents a collaboration support system, REGALMINER, that is able to capture, process, monitor and also visualize metadata from collaboration data streams taking advantage of text mining and information retrieval techniques like sentiment analysis (a.k.a. opinion mining) and keyword extraction. The analysis produces a set of scores that represent various meeting indicators that can be used to monitor and evaluate the dynamics of an ongoing collaborative process and to provide automatic interventions to enhance its effectiveness and efficiency. Information visualization techniques are used to present the results of the analysis to the participants of the current collaborative process or to the meeting coordinator, who supervises the meeting at runtime preventing the occurrence of deviations with respect to the meeting agenda and to make necessary interventions. © 2014 IEEE
Supporting elastic collaboration: Integration of collaboration components in dynamic contexts
No full textIn dynamic problem-solving situations, groups and organizations have to become more flexible to adapt collaborative workspaces according to their needs. New paradigms propose to bridge two opposing process and ad-hoc perspectives to achieve such flexibility. However, a key challenge relies on the dynamic integration of groupware tools in the same collaborative workspace. This paper proposes a collaborative workspace (Elgar) that supports the Elastic Collaboration concept, and a standard interface to realize the integration of groupware tools, named Elastic Collaboration Components. The paper illustrates the use of such flexible collaborative workspace and the use of groupware tools in a machine diagnosis scenario that requires collaboration. Copyright 2013 ACM
Engagement in Applied Games
No full textGames have been widely used for purposes other than entertainment due to their engaging nature. However, the concept of game engagement is still not well-defined, which limits its use in analysis and game design. The primary objective of this dissertation is to conceptualize game engagement to guide the analysis and design of applied games.The dissertation first explores the requirements for conceptualizing applied game engagement, identified through an analysis of three applied gaming projects and an empirical study. It then uses these requirements to develop the Applied Games Engagement Model (AGEM). The AGEM posits that engagement is the process of focusing attention on a task and that attention can be purposefully directed through design.The practical use of the AGEM is then explored by analyzing applied games. The theory is extended with relevant game design knowledge and applied to game design practice. This results in the Lens of Engagement for Applied Games, a unique way to view the design of an applied game.Overall, this dissertation provides a comprehensive perspective on applied game engagement, emphasizing the role of attention and its relation to game design. It offers a practical and workable method of considering and discussing game engagement, which can be used by anyone creating or studying applied games
Seamless Transition between Connected and Disconnected Collaborative Interaction
No full textNowadays, more and more users make use of web-based collaborative systems. Users participate in communities or search for and provide information in webbased systems. They access shared resources which they need for their professional life or for learning. One of the major prerequisites of such web-based systems is that users have to be connected to the network. But life has become much more mobile over the last years. While traveling, e.g. to the office or the university, users often are disconnected from the network. This makes it difficult to interact with other users or to access shared resources. An application supporting a seamless transition between connected and disconnected phases would allow users to work at any time and place while maintaining the advantages of a web-based collaborative system once they are online again. In this article, we describe the requirements that a web-based collaborative system has to fulfill to enable a nomadic use. We show how we extended the web-based collaborative system CURE to fulfill these requirements and how our approach can be transferred to other web-based collaborative systems
Evaluating coordination support mechanisms in an industrial engineering scenario
No full textNowadays, industrial engineering collaboration plays a crucial role along product development life cycle, especially for problem-solving and decision-making processes. This paper evaluates the acceptance of two coordination mechanisms for groups when working on a machine diagnosis report collaboratively. The evaluation is organized as a user study and is based on two hypothesis: groups will prefer unstructured over structured coordination, and groups using structured coordination will accomplish their task more efficiently. © 2014 Springer International Publishing
Personalized Personality Virtual Agents: Assessing the impacts of virtual agent’s personality match on user’s trust, personal attachment, perceived risk and purchase intention in e-commerce
No full textThe ever-increasing competition has led firms to higher adoption rate of technology to drive business efficiency and operation. One of the disruptive technologies of this century is Artificial Intelligence (AI), with virtual agents as one of its application. To get the maximum value of virtual agents, businesses attempt to personalize their chatbots by understanding their customers, using big data and machine learning. Aware of the significance of users’ personality, personality has also become the focus in achieving personalization. Meanwhile, personalization through chatbots personality(botsanality) has escaped the attention of researchers. This research investigated the impacts of personality match between human and computer in e-commerce by measuring level of trust, perceived risk and purchase intention. The experiment did not present statistically significant results and therefore rejecting the hypotheses.Management of Technology (MoT
Design Framework for Social Interaction with Location-based Games
No full textLocation-based games invite players to have new forms of meaningful social interactions with others and provide opportunities for players to engage with their own neighbourhood’s public space. Earlier research on user requirements for such games have identified seven different activity types that have proven to initiate social interaction and capture real life exchanges for meaningful play-based social experiences. Yet, current understanding on what makes these games successful in such endeavours is still insufficient. This study furthers current understanding on the effects of location-based games for social interaction in local communities: it studies the forms of social interaction that the previously identified seven types of game activities elicit by analysing the nature and types of the exchanges they trigger. Based on this analysis, a design framework is proposed to 1) analyse existing location-based games and describe the forms of social interaction they trigger, and 2) help practitioners design new game activities that target specific forms of social interaction. This contributes to the enhancement of current understanding on the impact that these games can have in local communities, and on the way they can be better designed and used to promote social exchanges that are desired by players.System Engineerin
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
