    Manifesto of computational social science

    Get PDF
    The increasing integration of technology into our lives has created unprecedented volumes of data on society’s everyday behaviour. Such data opens up exciting new opportunities to work towards a quantitative understanding of our complex social systems, within the realms of a new discipline known as Computational Social Science. Against a background of financial crises, riots and international epidemics, the urgent need for a greater comprehension of the complexity of our interconnected global society and an ability to apply such insights in policy decisions is clear. This manifesto outlines the objectives of this new scientific direction, considering the challenges involved in it, and the extensive impact on science, technology and society that the success of this endeavour is likely to bring about

    A survey on the evolution of the notion of context-awareness

    Get PDF
    The notion of Context has been considered for a long time in different areas of Computer Science. This article considers the use of context-based reasoning from the earlier perspective of AI as well as the newer developments in Ubiquitous Computing. Both communities have been somehow interested in the potential of context-reasoning to support real-time meaningful reactions from systems. We explain how the concept evolved in each of these different approaches. We found initially each of them considered this topic quite independently and separated from each other, however latest developments have started to show signs of cross-fertilization amongst these areas. The aim of our survey is to provide an understanding on the way context and context-reasoning were approached, to show that work in each area is complementary, and to highlight there are positive synergies arising amongst them. The overarching goal of this article is to encourage further and longer-term synergies between those interested in further understanding and using context-based reasoning

    Knowledge Management in Organizations: Gateway to Sustainable Competitive Performance

    Get PDF
    The important role of knowledge management as a strategic resource in a competitive business environment cannot be overemphasized. Today’s business is plagued with turbulence and stringent competition in the world market resulting in paradigmatic paralysis, and significant organizational changes that necessitate salient and innovative operational processes. For survival, organizations must monitor trends and adapt to both the external and internal environments, make changes in the form of innovation, improve operational processes, increase flexibility and adopt sustainable knowledge-creation activities. This study is qualitative. An in-depth review of literature was conducted across multiple online research databases, supported by accrued knowledge obtained from the author’s long work experience in the field of knowledge management. This study has three objectives: The first is to provide an overview of knowledge management; the second is to highlight the role of knowledge management in supporting organizational goals and objectives; the third is to provide strategies and pathways to a successful implementation of knowledge management. The study argues and justifies why knowledge management practices should be adopted by management. Pathways to achieving organizational success have been designed. Major advantages of implementing knowledge management were elaborated. Findings reveal that for an organization to effectively implement knowledge management, and to achieve optimal organizational performance, attention must be paid to three key components: - people, processes, and technology. These components should liaise strategically, with knowledge creation, sharing, and application processes. The paper strongly recommends knowledge management as the key to sustainable organizational performance

    A Systematic Literature Review of User Trust in AI-Enabled Systems: An HCI Perspective

    User trust in Artificial Intelligence (AI) enabled systems has been increasingly recognized and proven as a key element to fostering adoption. It has been suggested that AI-enabled systems must go beyond technical-centric approaches and towards embracing a more human centric approach, a core principle of the human-computer interaction (HCI) field. This review aims to provide an overview of the user trust definitions, influencing factors, and measurement methods from 23 empirical studies to gather insight for future technical and design strategies, research, and initiatives to calibrate the user AI relationship. The findings confirm that there is more than one way to define trust. Selecting the most appropriate trust definition to depict user trust in a specific context should be the focus instead of comparing definitions. User trust in AI-enabled systems is found to be influenced by three main themes, namely socio-ethical considerations, technical and design features, and user characteristics. User characteristics dominate the findings, reinforcing the importance of user involvement from development through to monitoring of AI enabled systems. In conclusion, user trust needs to be addressed directly in every context where AI-enabled systems are being used or discussed. In addition, calibrating the user-AI relationship requires finding the optimal balance that works for not only the user but also the system

    Distilling Privacy Requirements for Mobile Applications

    Get PDF
    As mobile computing applications have become commonplace, it is increasingly important for them to address end-users’ privacy requirements. Privacy requirements depend on a number of contextual socio-cultural factors to which mobility adds another level of contextual variation. However, traditional requirements elicitation methods do not sufficiently account for contextual factors and therefore cannot be used effectively to represent and analyse the privacy requirements of mobile end users. On the other hand, methods that do investigate contextual factors tend to produce data that does not lend itself to the process of requirements extraction. To address this problem we have developed a Privacy Requirements Distillation approach that employs a problem analysis framework to extract and refine privacy requirements for mobile applications from raw data gathered through empirical studies involving end users. Our approach introduces privacy facets that capture patterns of privacy concerns which are matched against the raw data. We demonstrate and evaluate our approach using qualitative data from an empirical study of a mobile social networking application

    Wearables at work:preferences from an employee’s perspective

    Get PDF
    This exploratory study aims to obtain a first impression of the wishes and needs of employees on the use of wearables at work for health promotion. 76 employ-ees with a mean age of 40 years old (SD ±11.7) filled in a survey after trying out a wearable. Most employees see the potential of using wearable devices for workplace health promotion. However, according to employees, some negative aspects should be overcome before wearables can effectively contribute to health promotion. The most mentioned negative aspects were poor visualization and un-pleasantness of wearing. Specifically for the workplace, employees were con-cerned about the privacy of data collection
