    Contextual Factors Affecting Information Sharing Patterns in Technology Mediated Communication

    In this thesis, we investigate how and what contextual factors affect user’s information sharing. We build our work on six individual research projects which cover a variety of systems (search engines, social network sites, teleconferencing systems, monitoring technology, and general purpose conversational agents) in a variety of communication scenarios with diverse relationships and dispositions of users. Alongside detailed findings for particular systems and communication scenarios from each individual project, we provide a consolidated analysis of these results across systems and scenarios, which allows us to identify patterns specific for different system types and aspects shared between systems. In particular, we show that depending on the system’s position between a user and an intended information receiving agent – whether communication happens through, around, or directly with the system – the system should have different patterns of operational adaptation to communication context. Specifically, when communication happens through the system, the system needs to gather communication context unavailable to the user and integrate it into information communication; when communication happens around the system, the system should adapt its operations to provide information in the most contextually suitable format; finally, when a user communicates with the system, the role of the system is to “match” this context in communication with the user. We then argue that despite the differences between system types in patterns of required context-based adaptation, there are contextual factors affecting user’s information sharing intent that should be acknowledged across systems. Grounded in our cumulative findings and analysis of related literature, we identify four such high-level contextual factors. We then present these four factors synthesized into an early design framework, which we call SART according to the included factors of space, addressee, reason, and time. Each factor in SART is presented as a continuum defined through a descriptive dichotomy: perceived breadth of communication space (public to private); perceived specificity of an information addressee (defined to undefined); intended reason for information sharing (instrumental to objective); and perceived time of information relevance and life-span (immediate to indefinite)

    Understanding people through the aggregation of their digital footprints

    Thesis (Ph. D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2011.Cataloged from PDF version of thesis.Includes bibliographical references (p. 160-172).Every day, millions of people encounter strangers online. We read their medical advice, buy their products, and ask them out on dates. Yet our views of them are very limited; we see individual communication acts rather than the person(s) as a whole. This thesis contends that socially-focused machine learning and visualization of archived digital footprints can improve the capacity of social media to help form impressions of online strangers. Four original designs are presented that each examine the social fabric of a different existing online world. The designs address unique perspectives on the problem of and opportunities offered by online impression formation. The first work, Is Britney Spears Span?, examines a way of prototyping strangers on first contact by modeling their past behaviors across a social network. Landscape of Words identifies cultural and topical trends in large online publics. Personas is a data portrait that characterizes individuals by collating heterogenous textual artifacts. The final design, Defuse, navigates and visualizes virtual crowds using metrics grounded in sociology. A reflection on these experimental endeavors is also presented, including a formalization of the problem and considerations for future research. A meta-critique by a panel of domain experts completes the discussion.by Aaron Robert Zinman.Ph.D

    On Making in the Digital Humanities

    Get PDF
    On Making in the Digital Humanities fills a gap in our understanding of digital humanities projects and craft by exploring the processes of making as much as the products that arise from it. The volume draws focus to the interwoven layers of human and technological textures that constitute digital humanities scholarship. To do this, it assembles a group of well-known, experienced and emerging scholars in the digital humanities to reflect on various forms of making (we privilege here the creative and applied side of the digital humanities). The volume honours the work of John Bradley, as it is totemic of a practice of making that is deeply informed by critical perspectives. A special chapter also honours the profound contributions that this volume’s co-editor, Stéfan Sinclair, made to the creative, applied and intellectual praxis of making and the digital humanities. Stéfan Sinclair passed away on 6 August 2020. The chapters gathered here are individually important, but together provide a very human view on what it is to do the digital humanities, in the past, present and future. This book will accordingly be of interest to researchers, teachers and students of the digital humanities; creative humanities, including maker spaces and culture; information studies; the history of computing and technology; and the history of science and the humanities

    Usability analysis of contending electronic health record systems

    In this paper, we report measured usability of two leading EHR systems during procurement. A total of 18 users participated in paired-usability testing of three scenarios: ordering and managing medications by an outpatient physician, medicine administration by an inpatient nurse and scheduling of appointments by nursing staff. Data for audio, screen capture, satisfaction rating, task success and errors made was collected during testing. We found a clear difference between the systems for percentage of successfully completed tasks, two different satisfaction measures and perceived learnability when looking at the results over all scenarios. We conclude that usability should be evaluated during procurement and the difference in usability between systems could be revealed even with fewer measures than were used in our study. © 2019 American Psychological Association Inc.

    Semantic discovery and reuse of business process patterns

    Get PDF
    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

    Augmenting Conversational Dialogue By Means of Latent Semantic Googling

    No full text
    This paper presents Latent Semantic Googling, a variant of Landauer’s Latent Semantic Indexing that uses the Google search engine to judge the semantic closeness of sets of words and phrases. This concept is implemented via Ambient Google, a system for augmenting conversations through the classification of discussed topics. Ambient Google uses a speech recognition engine to generate Google keyphrase queries directly from conversations. These queries are used to analyze the semantics of the conversation, and infer related topics that have been discussed. Conversations are visualized using a spring-model algorithm representing common topics. This allows users to browse their conversation as a contextual relationship between discussed topics, and augment their discussion through the use of related websites discovered by Google. An evaluation of Ambient Google is presented, discussing user reaction to the system

    The Dynamics of Influencer Marketing

    Get PDF
    YouTube, Instagram, Facebook, Vimeo, Twitter, etc. have their own logics, dynamics and different audiences. This book analyses how the users of these social networks, especially those of YouTube and Instagram, become content prescribers, opinion leaders and, by extension, people of influence. What influence capacity do they have? Why are intimate or personal aspects shared with unknown people? Who are the big beneficiaries? How much is vanity and how much altruism? What business is behind these social networks? What dangers do they contain? What volume of business can we estimate they generate? How are they transforming cultural industries? What legislation is applied? How does the legislation affect these communications when they are sponsored? Is the privacy of users violated with the data obtained? Who is the owner of the content? Are they to blame for ""fake news""? In this changing, challenging and intriguing environment, The Dynamics of Influencer Marketing discusses all of these questions and more. Considering this complexity from different perspectives: technological, economic, sociological, psychological and legal, the book combines the visions of several experts from the academic world and provides a structured framework with a wide approach to understand the new era of influencing, including the dark sides of it. It will be of direct interest to marketing scholars and researchers while also relevant to many other areas affected by the phenomenon of social media influence
